'''Mu'awiya I'''{{efn|{{langx|ar|معاوية بن أبي سفيان|Muʿāwiya ibn Abī Sufyān}}}} ({{circa|597, 603 or 605}}–April 680) was the founder and first [[caliph]] of the [[Umayyad Caliphate]], ruling from 661 until his death. He became caliph less than thirty years after the death of the Islamic prophet [[Muhammad]] and immediately after the four [[Rashidun Caliphate|Rashidun]] ('rightly-guided') caliphs. Unlike his predecessors, who had been close, early [[companions of Muhammad]], Mu'awiya was a relatively late follower of Muhammad.

Mu'awiya and his father [[Abu Sufyan]] had opposed Muhammad, their distant [[Quraysh]]ite kinsman and later Mu'awiya's brother-in-law, until Muhammad [[conquest of Mecca|captured Mecca]] in 630. Afterward, Mu'awiya became one of Muhammad's [[katib|scribe]]s. He was appointed by Caliph [[Abu Bakr]] ({{reign|632|634}}) as a deputy commander in the [[Muslim conquest of the Levant|conquest of Syria]]. He moved up the ranks through [[Umar]]'s caliphate ({{reign|634|644}}) until becoming governor of [[Bilad al-Sham|Syria]] during the reign of his [[Umayyad dynasty#Empowerment by Caliph Uthman|Umayyad kinsman]], Caliph [[Uthman]] ({{reign|644|656}}). He allied with the province's powerful [[Banu Kalb]] tribe, developed the defenses of its coastal cities, and directed the [[Arab–Byzantine wars|war effort]] against the [[Byzantine Empire]], including the first Muslim naval campaigns. In response to [[Siege of Uthman|Uthman's assassination]] in 656, Mu'awiya took up the cause of avenging the murdered caliph and opposed the election of [[Ali]]. During the [[First Muslim Civil War]], the two led their armies to a stalemate at the [[Battle of Siffin]] in 657, prompting an abortive series of arbitration talks to settle the dispute. Afterward, Mu'awiya gained recognition as caliph by his Syrian supporters and his ally [[Amr ibn al-As]], who conquered [[Egypt in the Middle Ages|Egypt]] from Ali's governor in 658. Following the [[assassination of Ali]] in 661, Mu'awiya compelled Ali's son and successor [[Hasan ibn Ali|Hasan]] to abdicate and Mu'awiya's [[suzerainty]] was acknowledged throughout the Caliphate.

Domestically, Mu'awiya relied on loyalist Syrian Arab tribes and Syria's Christian-dominated bureaucracy. He is credited with establishing [[divan|government departments]] responsible for the [[barid|postal route]], correspondence, and chancellery. He was the first caliph whose name appeared on coins, inscriptions, or documents of the nascent Islamic empire. Externally, he engaged his troops in almost yearly land and sea raids against the Byzantines, including a [[Siege of Constantinople (674–678)|failed siege of Constantinople]]. In [[Lower Mesopotamia|Iraq]] and the eastern provinces, he delegated authority to the powerful governors [[al-Mughira]] and [[Ziyad ibn Abi Sufyan]], the latter of whom he controversially adopted as his brother. Under Mu'awiya's direction, the Muslim conquest of [[Ifriqiya]] (central North Africa) was launched by the commander [[Uqba ibn Nafi]] in 670, while the conquests in [[Greater Khorasan|Khurasan]] and [[Sistan|Sijistan]] on the eastern frontier were resumed.

Although Mu'awiya confined the influence of his [[Umayyad dynasty|Umayyad clan]] to the governorship of [[Medina]], he nominated his own son, [[Yazid I]], as his successor. It was an unprecedented move in Islamic politics and opposition to it by prominent Muslim leaders, including Ali's son [[Husayn ibn Ali|Husayn]], and [[Abd Allah ibn al-Zubayr]], persisted after Mu'awiya's death, culminating with the outbreak of the [[Second Muslim Civil War]]. While there is considerable admiration for Mu'awiya in the contemporary sources, he has been criticized for lacking the justice and piety of the Rashidun and transforming the office of the caliphate into a kingship. Besides these criticisms, [[Sunni Muslim]] tradition honors him as a companion of Muhammad and a scribe of [[Qur'an]]ic revelation. In [[Shia Islam]], Mu'awiya is reviled for opposing Ali, accused of poisoning his son Hasan, and held to have accepted Islam without conviction.

==Origins and early life==
[[File:Age of the Caliphs-recolored (transparent).svg|thumb|upright=1|The Caliphate's growth. By the time Muhammad died in 632, Islam had spread throughout [[Arabia]] (green)]]

Mu'awiya's year of birth is uncertain, with 597, 603 or 605 cited by early Islamic sources.{{sfn|Hinds|1993|p=264}} His father [[Abu Sufyan ibn Harb]] was a prominent [[Mecca]]n merchant who led trade caravans to [[Syria (region)|Syria]], then part of the [[Byzantine Empire]].{{sfn|Watt|1960a|p=151}} He emerged as the leader of the [[Banu Abd Shams]] clan of the [[Religion in pre-Islamic Arabia|polytheistic]] [[Quraysh]], the dominant tribe of Mecca, during the early stages of the Quraysh's conflict with the [[Islam]]ic prophet [[Muhammad]].{{sfn|Hinds|1993|p=264}} The latter also hailed from the Quraysh and was distantly related to Mu'awiya via their common paternal ancestor, [[Abd Manaf ibn Qusayy]].{{sfn|Hawting|2000|pp=21–22}} Mu'awiya's mother, [[Hind bint Utba]], was also a member of the Banu Abd Shams.{{sfn|Hinds|1993|p=264}}

In 624, Muhammad and his followers attempted to intercept a Meccan caravan led by Mu'awiya's father on its return from Syria, prompting Abu Sufyan to call for reinforcements.{{sfn|Watt|1960b|p=868}} The Qurayshite relief army was routed in the ensuing [[Battle of Badr]], in which Mu'awiya's elder brother Hanzala and their maternal grandfather, [[Utbah ibn Rabi'ah]], were killed.{{sfn|Watt|1960a|p=151}} Abu Sufyan replaced the slain leader of the Meccan army, [[Abu Jahl]], and led the Meccans to victory against the [[Muslims]] at the [[Battle of Uhud]] in 625. After his abortive siege of Muhammad in [[Medina]] at the [[Battle of the Trench]] in 627, Abu Sufyan lost his leadership position among the Quraysh.{{sfn|Hinds|1993|p=264}}

Mu'awiya's father was not a participant in the [[Treaty of Hudaybiyya|truce negotiations at Hudaybiyya]] between the Quraysh and Muhammad in 628. The following year, Muhammad married Mu'awiya's widowed sister [[Umm Habiba]], who had embraced Islam fifteen years earlier. The marriage may have reduced Abu Sufyan's hostility toward Muhammad and Abu Sufyan negotiated with him in Medina in 630 after confederates of the Quraysh violated the Hudaybiyya truce.{{sfn|Watt|1960a|p=151}} When Muhammad [[conquest of Mecca|captured Mecca]] in 630, Mu'awiya, his father, and his elder brother [[Yazid ibn Abi Sufyan|Yazid]] embraced Islam. According to accounts cited by the early Muslim historians [[al-Baladhuri]] and [[Ibn Hajar al-Asqalani|Ibn Hajar]], Mu'awiya had secretly become a Muslim from the time of the Hudaybiyya negotiations.{{sfn|Hinds|1993|p=264}} By 632 Muslim authority extended across [[Arabia]] with Medina as the seat of the Muslim government.{{sfn|Wellhausen|1927|pp=22–23}} As part of Muhammad's efforts to reconcile with the Quraysh, Mu'awiya was made one of his {{transliteration|ar|[[kātib]]s}} (scribes), being one of seventeen literate members of the Quraysh at that time.{{sfn|Hinds|1993|p=264}} Abu Sufyan moved to Medina to maintain his newfound influence in the [[ummah|nascent Muslim community]].{{sfn|Wellhausen|1927|pp=20–21}}

==Governorship of Syria==
===Early military career and administrative promotions===
[[File:Early Islamic Syria, ca. 640s.png|thumb|upright=1.75|alt=A map with shaded areas showing the expansion of the Islamic empire on overlay showing the borders of modern countries|Map of the region of [[Bilad al-Sham|Syria]] in the first decades of Islamic rule]]

After Muhammad died in 632, [[Abu Bakr]] became [[caliph]] (leader of the Muslim community).{{sfn|Lewis|2002|p=49}} He and his successors [[Umar]], [[Uthman]], and [[Ali]] are often known as the {{transliteration|ar|[[Rashidun Caliphate|Rashidun]]}} ('rightly-guided') caliphs to distinguish them from Mu'awiya and his [[Umayyad Caliphate|Umayyad]] dynastic successors.{{sfn|Kennedy|2004|p=52}} Having to contend with challenges to his leadership from the [[Ansar (Islam)|Ansar]], the natives of Medina who had provided Muhammad safe haven from his erstwhile Meccan opponents, and the mass defections of several [[Arab]] tribes, Abu Bakr reached out to the Quraysh, particularly its two strongest clans, the [[Banu Makhzum]] and Banu Abd Shams, to shore up support for the Caliphate.{{sfn|Kennedy|2004|p=54}} Among those Qurayshites whom he appointed to suppress the rebel Arab tribes during the [[Ridda wars]] (632–633) was Mu'awiya's brother Yazid. After that war, Yazid was dispatched as one of four commanders in charge of the [[Muslim conquest of the Levant|Muslim conquest of Byzantine Syria]] in {{circa|634}}.{{sfn|Madelung|1997|p=45}} The caliph appointed Mu'awiya commander of Yazid's vanguard.{{sfn|Hinds|1993|p=264}} Through these appointments Abu Bakr gave the family of Abu Sufyan a stake in the conquest of Syria, where Abu Sufyan already owned property in the vicinity of [[Damascus]].{{sfn|Madelung|1997|p=45}}{{efn|According to [[al-Baladhuri]], Abu Sufyan owned a village in the [[Balqa (region)|Balqa]] region, which formed part of the [[Jund Dimashq|Damascus district]]. The 13th-century Syrian geographer [[Yaqut al-Hamawi]] identified it as a village called Biqinis.{{sfn|Fowden|2004|p=151, note 54}}}}

Abu Bakr's successor Umar ({{reign|634|644}}) appointed a leading companion of Muhammad, [[Abu Ubayda ibn al-Jarrah]], as the general commander of the Muslim army in Syria in 636 after the rout of the Byzantines at the [[Battle of Yarmouk]],{{sfn|Athamina|1994|p=259}} which paved the way for the conquest of the rest of Syria.{{sfn|Donner|2014|pp=133–134}} Mu'awiya was among the Arab troops who [[Siege of Jerusalem (636–637)|entered Jerusalem]] with Caliph Umar in 637.{{sfn|Hinds|1993|p=264}}{{efn|Mu'awiya is probably the 'Mu'awiya' mentioned as the 'writer' in an Arabic inscription, apparently dated to 652, excavated at the southwestern section of the [[Temple Mount]] in 1968. The inscription consists of nine lines, only few of which are legible, that the historian [[Moshe Sharon]] tentatively concludes relate to the [[siege of Jerusalem (637)|capitulation of Jerusalem]] to the Muslims {{circa|637}}. [[Abu Ubayda ibn al-Jarrah]] and [[Abd al-Rahman ibn Awf]], two other [[companions of Muhammad]] who reports in the early Islamic sources connect to the city's conquest, are mentioned as witnesses. The date of the inscription is several years after Abu Ubayda's death and roughly corresponds with the death of Abd al-Rahman, but coincides with the governorship of Mu'awiya, who was a [[katib|scribe]]. Sharon thus surmises the inscription was a legal document written by Mu'awiya to commemorate the surrender.{{sfn|Sharon|2018|pp=100–101, 108–109}}}} Afterward, Mu'awiya and Yazid were dispatched by Abu Ubayda to conquer the coastal towns of [[Sidon]], [[Beirut]] and [[Byblos]].{{sfn|Donner|2014|p=154}} Following the death of Abu Ubayda in the [[plague of Amwas]] in 639, Umar split the command of Syria, appointing Yazid as governor of the [[jund|military district]]s of [[Jund Dimashq|Damascus]], [[Jund al-Urdunn|Jordan]] and [[Jund Filastin|Palestine]], and the veteran commander [[Iyad ibn Ghanm]] governor of [[Jund Hims|Homs]] and the [[Al-Jazira (caliphal province)|Jazira]] (Upper [[Mesopotamia]]).{{sfn|Hinds|1993|p=264}}{{sfn|Madelung|1997|pp=60–61}} When Yazid succumbed to the plague later that year, Umar appointed Mu'awiya the military and fiscal governor of Damascus, and possibly Jordan as well.{{sfn|Hinds|1993|p=264}}{{sfn|Madelung|1997|p=61}} In 640 or 641, Mu'awiya captured [[Caesarea Maritima|Caesarea]], the district capital of [[Palaestina Prima|Byzantine Palestine]], and then captured [[Ashkelon|Ascalon]], completing the Muslim conquest of Palestine.{{sfn|Hinds|1993|p=264}}{{sfn|Donner|2014|p=153}}{{sfn|Sourdel|1965|p=911}} As early as 640 or 641, Mu'awiya may have led a campaign against [[Cilicia]] and proceeded to [[Euchaita]], deep in Byzantine [[Anatolia]].{{sfn|Kaegi|1995|pp=67, 246}} In 644, he led a foray against the Anatolian city of [[Amorium]].{{sfn|Kaegi|1995|p=245}}

The successive promotions of Abu Sufyan's sons contradicted Umar's efforts to otherwise curtail the influence of the Qurayshite aristocracy in the Muslim state in favor of the earliest Muslim converts (i.e. the [[Muhajirun]] and [[Ansar (Islam)|Ansar]] groups).{{sfn|Madelung|1997|pp=60–61}} According to the historian [[Leone Caetani]], this exceptional treatment stemmed from Umar's personal respect for the [[Umayyad dynasty|Umayyads]], the branch of the Banu Abd Shams to which Mu'awiya belonged.{{sfn|Madelung|1997|p=61}} This is doubted by the historian [[Wilferd Madelung]], who surmises that Umar had little choice, due to the lack of a suitable alternative to Mu'awiya in Syria and the ongoing plague in the region, which precluded the deployment of commanders more preferable to Umar from Medina.{{sfn|Madelung|1997|p=61}}

Upon the accession of Caliph Uthman ({{reign|644|656}}), Mu'awiya's governorship was enlarged to include Palestine, while a companion of Muhammad, [[Umayr ibn Sa'd al-Ansari]], was confirmed as governor of the Homs-Jazira district. In late 646 or early 647, Uthman attached the Homs-Jazira district to Mu'awiya's Syrian governorship,{{sfn|Hinds|1993|p=264}} greatly increasing the military manpower at his disposal.{{sfn|Donner|2012|p=152}}

===Consolidation of local power===
During the reign of Uthman, Mu'awiya allied with the [[Banu Kalb]],{{sfn|Dixon|1978|p=493}} the predominant tribe in the [[Syrian steppe]] extending from the oasis of [[Dumat al-Jandal]] in the south to the approaches of [[Palmyra]]. The Kalb was also the chief component of the [[Quda'a]] confederation, which was present throughout Syria.{{sfn|Lammens|1960|p=920}}{{sfn|Donner|2014|p=106}}{{sfn|Marsham|2013|p=104}} Medina consistently courted the Kalb, which had remained mostly neutral during the Arab–Byzantine wars, particularly after the central government's entreaties to the Byzantines' principal Arab allies, the Christian [[Ghassanids]], were rebuffed.{{sfn|Athamina|1994|p=263}}{{efn|According to the historian Khalil Athamina, Caliph [[Umar]]'s efforts to make the native Syrian Arab tribes the foundation of [[Bilad al-Sham|Syria]]'s defense from a [[Byzantine Empire|Byzantine]] counterattack was the main cause of [[Khalid ibn al-Walid]]'s dismissal from the general command in Syria and the subsequent recall to Iraq of the numerous tribesmen in Khalid's army, who were likely perceived as a threat by the [[Banu Kalb]] and its allies, in 636.{{sfn|Athamina|1994|pp=262, 265–268}} The [[Quraysh]] and the early Muslim elite sought to secure Syria, with which they had long been acquainted, for themselves and encouraged the nomadic Arab late converts among the Muslim troops to immigrate to Iraq.{{sfn|Kennedy|2007|p=95}} According to Madelung, Umar may have promoted [[Yazid ibn Abi Sufyan|Yazid]] and Mu'awiya as guarantors of the Caliphate's authority in Syria against the growing "strength and high ambitions" of the [[South Arabia]]n, aristocratic [[Himyarite Kingdom#Tribal presence in Syria and Egypt (7th–8th centuries)|Himyarite]]s, who had played a prominent role in the Muslim conquest.{{sfn|Madelung|1997|p=61}}}} Before the advent of Islam in Syria, the Kalb and the Quda'a, long under the influence of [[History of Syria#Classical antiquity|Greco-Aramaic culture]] and the [[Monophysite]] church,{{sfn|Hinds|1993|p=267}}{{sfn|Wellhausen|1927|pp=55, 132}} had served Byzantium as subordinates of its Ghassanid [[phylarch|client king]]s to guard the [[limes Arabicus|Syrian frontier]] against invasions by the [[Sasanian Empire|Sasanian Persian]]s and the latter's Arab clients, the [[Lakhmids]].{{sfn|Hinds|1993|p=267}} By the time the Muslims entered Syria, the Kalb and the Quda'a had accumulated significant military experience and were accustomed to hierarchical order and military obedience.{{sfn|Wellhausen|1927|pp=55, 132}} To harness their strength and thereby secure his foothold in Syria, Mu'awiya consolidated ties to the Kalb's ruling house, the clan of [[Bahdal ibn Unayf]], by wedding the latter's daughter [[Maysun bint Bahdal|Maysun]] in {{circa|650}}.{{sfn|Dixon|1978|p=493}}{{sfn|Marsham|2013|p=104}}{{sfn|Humphreys|2006|p=61}} He also married Maysun's paternal cousin, Na'ila bint Umara, for a short period.{{sfn|Morony|1987|p=215}}{{efn|After Mu'awiya divorced Na'ila bint Umara al-Kalbiyya, she was wed to Mu'awiya's close aide [[Habib ibn Maslama al-Fihri]] and after the latter's death, to another of Mu'awiya's close aides, [[Nu'man ibn Bashir al-Ansari]].{{sfn|Morony|1987|pp=215–216}}}}

Mu'awiya's reliance on the native Syrian Arab tribes was compounded by the heavy toll inflicted on the Muslim troops in Syria by the plague of Amwas,{{sfn|Jandora|1986|p=111}} which caused troop numbers to dwindle from 24,000 in 637 to 4,000 in 639.{{sfn|Donner|2014|p=245}} Moreover, the focus of Arabian tribal migration was toward the [[Muslim conquest of Persia|Sasanian front in Iraq]].{{sfn|Jandora|1986|p=111}} Mu'awiya oversaw a liberal recruitment policy that resulted in considerable numbers of Christian tribesmen and frontier peasants filling the ranks of his regular and auxiliary forces.{{sfn|Jandora|1986|p=112}} Indeed, the Christian [[Tanukhids]] and the mixed Muslim–Christian [[Banu Tayy]] formed part of Mu'awiya's army in northern Syria.{{sfn|Shahid|2000a|p=191}}{{sfn|Shahid|2000b|p=403}} To help pay for his troops, Mu'awiya requested and was granted ownership by Uthman of the abundant, income-producing, Byzantine crown lands in Syria, which were previously designated by Umar as communal property for the Muslim army.{{sfn|Madelung|1997|p=82}}

Although Syria's rural, [[Aramaic]]-speaking Christian population remained largely intact,{{sfn|Donner|2014|pp=248–249}} the Muslim conquest had caused a mass flight of [[Rum (endonym)|Greek Christian]] urbanites from Damascus, [[Aleppo]], [[Latakia]] and [[Tripoli, Lebanon|Tripoli]] to Byzantine territory,{{sfn|Donner|2014|p=245}} while those who remained held pro-Byzantine sympathies.{{sfn|Jandora|1986|p=111}} In contrast to the other conquered regions of the Caliphate, where new [[amsar|garrison cities]] were established to house Muslim troops and their administration, in Syria the troops settled in existing cities, including Damascus, Homs, Jerusalem, [[Tiberias]],{{sfn|Donner|2014|p=245}} Aleppo and [[Qinnasrin]].{{sfn|Kennedy|2007|p=95}} Mu'awiya restored, repopulated and garrisoned the coastal cities of [[Antioch]], [[Arab al-Mulk|Balda]], [[Tartus]], [[Maraclea]] and [[Baniyas]].{{sfn|Jandora|1986|p=111}} In Tripoli he settled significant numbers of [[Jew]]s,{{sfn|Jandora|1986|p=111}} while sending to Homs, Antioch and [[Baalbek]] [[Persian people|Persian]] holdovers from the [[Byzantine–Sasanian War of 602–628|Sasanian occupation of Byzantine Syria]] in the early 7th century.{{sfn|Kennedy|2001|p=12}} Upon Uthman's direction, Mu'awiya settled groups of the nomadic [[Banu Tamim|Tamim]], [[Banu Asad|Asad]] and [[Qays]] tribes to areas north of the [[Euphrates]] in the vicinity of [[Raqqa]].{{sfn|Jandora|1986|p=111}}{{sfn|Donner|2014|p=248}}

===Naval campaigns against Byzantium and conquest of Armenia===
Mu'awiya initiated the Arab naval campaigns against the Byzantines in the eastern Mediterranean,{{sfn|Hinds|1993|p=264}} requisitioning the harbors of Tripoli, Beirut, [[Tyre, Lebanon|Tyre]], [[Acre, Israel|Acre]], and [[Jaffa]].{{sfn|Jandora|1986|p=112}}{{sfn|Bosworth|1996|p=157}} Umar had rejected Mu'awiya's request to launch a naval invasion of [[Cyprus]], citing concerns about the Muslim forces' safety at sea, but Uthman allowed him to commence the campaign in 647, after refusing an earlier entreaty.{{sfn|Lynch|2016|p=539}} Mu'awiya's rationale was that the Byzantine-held island posed a threat to Arab positions along the Syrian coast, and that it could be easily neutralized.{{sfn|Lynch|2016|p=539}} The exact year of the raid is unclear, with the early Arabic sources providing a range between 647 and 650, while two [[Greek language|Greek]] inscriptions in the Cypriot village of [[Soli, Cyprus|Solois]] cite two raids launched between 648 and 650.{{sfn|Lynch|2016|p=539}}

According to the 9th-century historians al-Baladhuri and [[Khalifa ibn Khayyat]], Mu'awiya led the raid in person accompanied by his wife, Katwa bint Qaraza ibn Abd Amr of the Qurayshite [[Banu Nawfal]], alongside the commander [[Ubada ibn as-Samit|Ubada ibn al-Samit]].{{sfn|Morony|1987|pp=215–216}}{{sfn|Lynch|2016|p=539}} Katwa died on the island and at some point Mu'awiya married her sister Fakhita.{{sfn|Morony|1987|pp=215–216}} In a different narrative by the early Muslim sources, the raid was instead conducted by Mu'awiya's admiral [[Abdallah ibn Qais]], who landed at [[Salamis, Cyprus|Salamis]] before occupying the island.{{sfn|Bosworth|1996|p=157}} In either case, the Cypriots were forced to pay a tribute equal to that which they had paid the Byzantines.{{sfn|Bosworth|1996|p=157}}{{sfn|Lynch|2016|p=540}} Mu'awiya established a garrison and a mosque to maintain the Caliphate's influence on the island, which became a staging ground for the Arabs and the Byzantines to launch raids against each other's territories.{{sfn|Lynch|2016|p=540}} The inhabitants of Cyprus were largely left to their own devices and archaeological evidence indicates uninterrupted prosperity during this period.{{sfn|Lynch|2016|pp=541–542}}

Dominance of the eastern Mediterranean enabled Mu'awiya's naval forces to raid [[Crete]] and [[Rhodes]] in 653. From the raid on Rhodes, Mu'awiya remitted significant war spoils to Uthman.{{sfn|Bosworth|1996|p=158}} In 654 or 655, a joint naval expedition launched from [[Alexandria]], Egypt and the harbors of Syria routed a Byzantine fleet commanded by the Byzantine Emperor [[Constans II]] ({{reign|641|668}}) off the [[Lycia]]n coast at the [[Battle of the Masts]]. Constans II was forced to sail to [[Sicily]], opening the way for an ultimately unsuccessful [[Battle of the Masts#Siege of Constantinople of 654|Arab naval attack on Constantinople]].{{sfn|Bosworth|1996|pp=157–158}} The Arabs were commanded by either the governor of Egypt, [[Abdallah ibn Sa'd|Abd Allah ibn Abi Sarh]], or Mu'awiya's lieutenant [[Abu'l-A'war]].{{sfn|Bosworth|1996|pp=157–158}}

Meanwhile, after two previous attempts by the Arabs to conquer [[Arminiya|Armenia]], the third attempt in 650 ended with a three-year truce reached between Mu'awiya and the Byzantine envoy Procopios in Damascus.{{sfn|Kaegi|1995|pp=184–185}} In 653, Mu'awiya received the submission of the Armenian leader [[Theodore Rshtuni]], which the Byzantine emperor practically conceded when he withdrew from Armenia that year.{{sfn|Kaegi|1995|p=185}} In 655, Mu'awiya's lieutenant commander [[Habib ibn Maslama al-Fihri]] captured [[Erzerum|Theodosiopolis]] and deported Rshtuni to Syria, solidifying Arab rule over Armenia.{{sfn|Kaegi|1995|p=185}}

==First Fitna==

Mu'awiya's domain was generally immune to the growing discontent prevailing in Medina, Egypt and [[Kufa]] against Uthman's policies in the 650s. The exception was [[Abu Dharr al-Ghifari]],{{sfn|Hinds|1993|p=264}} who had been sent to Damascus for openly condemning Uthman's enrichment of his kinsmen.{{sfn|Madelung|1997|p=84}} He criticized the lavish sums that Mu'awiya invested in building his Damascus residence, the [[Khadra Palace]], prompting Mu'awiya to expel him.{{sfn|Madelung|1997|p=84}} Uthman's confiscation of crown lands in Iraq and his alleged nepotism{{efn|Uthman's efforts to maintain Qurayshite control over the Caliphate and assert control over the loose financial system of Umar,{{sfn|Kennedy|2004|p=70}}{{sfn|Donner|2012|pp=152–153}} saw the appointment of his close relatives from the [[Umayyad dynasty|Banu Umayya]] and its parent clan the [[Banu Abd Shams]] to all of the Caliphate's major governorships. These provincial appointments included Syria and the [[Al-Jazira (caliphal province)|Jazira]] under his Umayyad cousin Mu'awiya, [[Kufa]] successively under the Umayyads [[al-Walid ibn Uqba]] and [[Sa'id ibn al-As]], Basra with [[Eastern Arabia|Bahrayn]] and [[History of Oman|Oman]] under Uthman's maternal cousin [[Abd Allah ibn Amir]] of the Banu Abd Shams, [[Mecca]] under Ali ibn Adi ibn Rabi'a of the Banu Abd Shams, and [[Egypt in the Middle Ages|Egypt]] under Uthman's foster brother [[Abd Allah ibn Abi Sarh]]. He also relied on his Umayyad cousin [[Marwan ibn al-Hakam]] in his internal decision-making.{{sfn|Madelung|1997|pp=86–87}} Uthman demanded that the surplus revenue from the conquered lands, which had been declared state property by Umar but remained under the control of the conquering tribesmen, be forwarded to Medina.

Uthman sent for assistance from Mu'awiya when rebels from Egypt [[siege of Uthman|besieged his home]] in June 656. Mu'awiya dispatched a relief army toward Medina, but it withdrew at [[Wadi al-Qura]] when word reached them of Uthman's killing.{{sfn|Hinds|1993|p=265}} Ali, Muhammad's cousin and son-in-law, was recognized as caliph in Medina.{{sfn|Lewis|2002|p=62}} Mu'awiya withheld allegiance to Ali{{sfn|Humphreys|2006|p=74}} and, according to some reports, the latter deposed him by sending his own governor to Syria, who was denied entry into the province by Mu'awiya.{{sfn|Lewis|2002|p=62}} This is rejected by Madelung, according to whom no formal relations existed between the caliph and the governor of Syria for seven months from the date of Ali's election.{{sfn|Madelung|1997|p=184}}

Soon after becoming caliph, Ali was opposed by much of the Quraysh led by [[al-Zubayr ibn al-Awwam|al-Zubayr]] and [[Talha ibn Ubayd Allah|Talha]], both prominent companions of Muhammad, and Muhammad's wife [[A'isha]], who feared the loss of their own influence under Ali.{{sfn|Hawting|2000|p=27}} The ensuing civil war became known as the [[First Fitna]].{{efn|Historically, the term {{transliteration|ar|[[fitna (word)|fitna]]}} came to mean a civil war or rebellion which causes rifts in the unified Muslim community and endangers believers' faith.{{sfn|Gardet|1965|p=930}}}} Ali defeated the triumvirate near [[Basra]] at the [[Battle of the Camel]], which ended in the deaths of al-Zubayr and Talha, both potential contenders for the caliphate, and the retirement of A'isha to Medina.{{sfn|Hawting|2000|p=27}} With his position in Iraq, Egypt and Arabia secure, Ali turned his attention toward Mu'awiya. Unlike the other provincial governors, Mu'awiya had a strong and loyal power base, demanded revenge for the slaying of his Umayyad kinsman Uthman, and could not be easily replaced.{{sfn|Wellhausen|1927|p=55–56, 76}}{{sfn|Kennedy|2004|p=76}} At this point, Mu'awiya did not yet claim the caliphate and his principal aim was keeping power in Syria.{{sfn|Humphreys|2006|p=77}}{{sfn|Hawting|2000|p=28}}

===Preparations for war===
{{See also|Umayyad invasions of Egypt}}

Ali's victory in Basra left Mu'awiya vulnerable, his territory wedged between Ali's forces in Iraq and Egypt, while the war with the Byzantines was ongoing in the north.{{sfn|Wellhausen|1927|p=76}} In 657 or 658 Mu'awiya secured his northern frontier with Byzantium by making a truce with the emperor, enabling him to focus the bulk of his troops on the impending battle with the caliph.{{sfn|Shaban|1976|p=74}} After failing to gain the defection of Egypt's governor, [[Qays ibn Sa'd]], he resolved to end the Umayyad family's hostility to Amr ibn al-As, the conqueror and former governor of Egypt, whom they accused of involvement in Uthman's death.{{sfn|Madelung|1997|pp=191, 196}} Mu'awiya and Amr, who was popular with the Arab troops of Egypt, made a pact whereby the latter joined the coalition against Ali and Mu'awiya publicly agreed to install Amr as Egypt's lifetime governor should they oust Ali's appointee.{{sfn|Madelung|1997|pp=196–197}}

Although he had the firm backing of the Kalb, to shore up the rest of his base in Syria, Mu'awiya was advised by his kinsman [[al-Walid ibn Uqba]] to secure an alliance with the [[Tribes of Yemen|Yemenite tribes]] of [[Himyarites#Himyarite dynasties after the coming of Islam|Himyar]], [[Kinda (tribe)|Kinda]] and [[Banu Hamdan|Hamdan]], who collectively dominated the Homs garrison. He employed the veteran commander and Kindite nobleman [[Shurahbil ibn Simt]], who was widely respected in Syria, to rally the Yemenites to his side.{{sfn|Madelung|1997|pp=199–200}} He then enlisted support from the dominant tribal leader of Palestine, the [[Judham]] chief [[Natil ibn Qays]], by allowing the latter's confiscation of the district's treasury to go unpunished.{{sfn|Madelung|1997|p=224}} The efforts bore fruit and demands for war against Ali grew throughout Mu'awiya's domain.{{sfn|Madelung|1997|p=203}} When Ali sent his envoy, the veteran commander and chieftain of the [[Bajila]], [[Jarir al-Bajali|Jarir ibn Abd Allah]], to Mu'awiya, the latter responded with a letter that amounted to a declaration of war against the caliph, whose legitimacy he refused to recognize.{{sfn|Madelung|1997|pp=204–205}}

===Battle of Siffin and arbitration===
{{Main|Battle of Siffin}}

In the first week of June 657, the armies of Mu'awiya and Ali [[Battle of Siffin|met at Siffin]] near Raqqa and engaged in days of skirmishes interrupted by a month-long truce on 19 June.{{sfn|Madelung|1997|pp=225–226, 229}} During the truce, Mu'awiya dispatched an embassy led by Habib ibn Maslama, who presented Ali with an ultimatum to hand over Uthman's alleged killers, abdicate and allow a {{transliteration|ar|[[shura]]}} (consultative council) to decide the caliphate. Ali rebuffed Mu'awiya's envoys and on 18 July declared that the Syrians remained obstinate in their refusal to recognize his sovereignty. On the following day, a week of duels between Ali's and Mu'awiya's top commanders ensued.{{sfn|Madelung|1997|pp=230–231}} The main battle between the two armies commenced on 26 July.{{sfn|Lewis|2002|p=63}} As Ali's troops advanced toward Mu'awiya's tent, Mu'awiya ordered his elite troops forward and they bested the Iraqis before the tide turned against the Syrians the next day with the deaths of two of Mu'awiya's leading commanders, [[Ubayd Allah ibn Umar|Ubayd Allah]], a son of Caliph Umar, and [[Dhu'l-Kala Samayfa]], the so-called 'king of Himyar'.{{sfn|Madelung|1997|pp=232–233}}

[[File:Muawiya Liwa' (3).png|thumb|upright=0.8|alt=a representation of a flag standard, with separated red and yellow banners|The standard ({{transliteration|ar|[[Liwa (Arabic)|liwa]]}}) of Mu'awiya at the [[Battle of Siffin]]]]

Mu'awiya rejected suggestions from his advisers to engage Ali in a duel and definitively end hostilities.{{sfn|Madelung|1997|p=235}} The battle climaxed on the so-called 'Night of Clamor' on 28 July, which saw Ali's forces take the advantage in a [[melée]] as the death toll mounted on both sides.{{sfn|Vaglieri|1960|p=383}}{{efn|The consensus in the early Muslim sources holds that Caliph [[Ali]]'s Iraqi forces gained the advantage during the battle prompting the Syrians to appeal for a settlement by arbitration. This is contrasted by a number of early non-Muslim sources, including [[Theophanes the Confessor]], according to whom the Syrians were victorious, an assertion supported by [[Umayyad Caliphate|Umayyad]] court poetry.{{sfn|Hinds|1993|p=265}}{{sfn|Crone|2003|p=203, note 30}}}} According to the account of the scholar [[Ibn Shihab al-Zuhri|al-Zuhri]] (d. 742), this prompted Amr ibn al-As to counsel Mu'awiya the following morning to have a number of his men tie leaves of the Qur'an on their lances in an appeal to the Iraqis to settle the conflict through consultation. According to the scholar [[Amir al-Sha'bi|al-Sha'bi]] (d. 723), [[al-Ash'ath ibn Qays]], who was in Ali's army, expressed his fears of Byzantine and Persian attacks were the Muslims to exhaust themselves in the civil war. Upon receiving intelligence of this, Mu'awiya ordered the raising of the Qur'an leaves.{{sfn|Hinds|1972|pp=93–94}} Though this act represented a surrender of sorts as Mu'awiya abandoned, at least temporarily, his previous insistence on settling the dispute with Ali militarily and pursuing Uthman's killers into Iraq, it had the effect of sowing discord and uncertainty in Ali's ranks.{{sfn|Madelung|1997|p=238}}

The caliph adhered to the will of the majority in his army and accepted the proposal to arbitrate.{{sfn|Hinds|1972|p=98}} Moreover, Ali agreed to Amr's, or Mu'awiya's, demand to omit his formal title, {{transliteration|ar|[[amir al-mu'minin]]}} (commander of the faithful, the traditional title of a caliph), from the initial arbitration document.{{sfn|Hinds|1972|p=100}} According to the historian [[Hugh N. Kennedy]], the agreement forced Ali "to deal with Mu'awiya on equal terms and abandon his unchallenged right to lead the community".{{sfn|Kennedy|2004|p=79}} Madelung asserts it "handed Mu'awiya a moral victory" before inducing a "disastrous split in the ranks of Ali's men".{{sfn|Madelung|1997|p=245}} Indeed, upon Ali's return to his capital Kufa in September 658, a large segment of his troops who had opposed the arbitration defected, inaugurating the [[Kharijite]] movement.{{sfn|Donner|2012|p=162}}

The initial agreement postponed the arbitration to a later date.{{sfn|Vaglieri|1960|p=383}}{{sfn|Hinds|1972|p=101}} Information in the early Muslim sources about the time, place and outcome of the arbitration is contradictory, but there were likely two meetings between Mu'awiya's and Ali's respective representatives, Amr and [[Abu Musa al-Ash'ari]], the first in Dumat al-Jandal and the last in [[Adhruh]].{{sfn|Madelung|1997|pp=254–255}} Ali abandoned the arbitration after the first meeting in which Abu Musa—who, unlike Amr, was not particularly attached to his principal's cause—{{sfn|Hinds|1972|p=99}} accepted the Syrian side's claim that Uthman was wrongfully killed, a verdict that Ali opposed.{{sfn|Donner|2012|pp=162–163}} The final meeting in Adhruh, which had been convened at Mu'awiya's request, collapsed, but by then Mu'awiya had emerged as a major contender for the caliphate.{{sfn|Donner|2012|p=165}}

Following the breakdown of the arbitration talks, Amr and the Syrian delegates returned to Damascus, where they greeted Mu'awiya as {{transliteration|ar|amir al-mu'minin}}, signaling their recognition of him as caliph.{{sfn|Madelung|1997|p=257}} In April or May 658, Mu'awiya received a general [[bay'ah|pledge of allegiance]] from the Syrians.{{sfn|Hinds|1993|p=265}} In response, Ali broke off communications with Mu'awiya, mobilized for war and invoked a curse against Mu'awiya and his close retinue as a ritual in the morning prayers.{{sfn|Madelung|1997|p=257}} Mu'awiya reciprocated in kind against Ali and his closest supporters in his own domain.{{sfn|Madelung|1997|p=258}}

In July, Mu'awiya dispatched an army under Amr to Egypt after a request for intervention from pro-Uthman mutineers in the province who were being suppressed by the governor, Caliph Abu Bakr's son and Ali's stepson, [[Muhammad ibn Abi Bakr|Muhammad]].{{sfn|Kennedy|1998|p=69}} The latter's troops were defeated by Amr's forces, the provincial capital [[Fustat]] was captured and Muhammad was executed on the orders of [[Mu'awiya ibn Hudayj]], leader of the pro-Uthman rebels.{{sfn|Kennedy|1998|p=69}} The loss of Egypt was a major blow to the authority of Ali, who was bogged down [[Battle of Nahrawan|battling Kharijite defectors]] in Iraq and whose grip in Basra and Iraq's eastern and southern dependencies was eroding.{{sfn|Hinds|1993|p=265}}{{sfn|Wellhausen|1927|p=99}} Though his hand was strengthened, Mu'awiya refrained from launching a direct assault against Ali.{{sfn|Wellhausen|1927|p=99}} Instead, his strategy was to bribe the tribal chieftains in Ali's army to his side and harry the inhabitants along Iraq's western frontier.{{sfn|Wellhausen|1927|p=99}} The first raid was conducted by [[al-Dahhak ibn Qays al-Fihri]] against nomads and Muslim pilgrims in the desert west of Kufa.{{sfn|Madelung|1997|pp=262–263, 287}} This was followed by [[Nu'man ibn Bashir al-Ansari]]'s abortive attack on [[Ayn al-Tamr]] then, in the summer of 660, [[Sufyan ibn Awf]]'s successful raids against [[Hīt|Hit]] and [[Anbar (town)|Anbar]].{{sfn|Wellhausen|1927|p=100}}

In 659 or 660, Mu'awiya expanded the operations to the [[Hejaz]] (western Arabia, where Mecca and Medina are located), sending [[Abd Allah ibn Mas'ada al-Fazari]] to collect the [[sadaqat|alms tax]] and oaths of allegiance to Mu'awiya from the inhabitants of the [[Tayma]] oasis. This initial foray was defeated by the Kufans,{{sfn|Madelung|1997|p=289}} while an attempt to extract oaths of allegiance from the Quraysh of Mecca in April 660 also failed.{{sfn|Madelung|1997|pp=290–292}}

In the summer, Mu'awiya dispatched a large army under [[Busr ibn Abi Artat]] to conquer the Hejaz and Yemen. He directed Busr to intimidate Medina's inhabitants without harming them, spare the Meccans and kill anyone in Yemen who refused to pledge their allegiance.{{sfn|Madelung|1997|pp=299–300}} Busr advanced through Medina, Mecca and [[Ta'if]], encountering no resistance and gaining those cities' recognition of Mu'awiya.{{sfn|Madelung|1997|pp=301–303}} In Yemen, Busr executed several notables in [[Najran]] and its vicinity on account of past criticism of Uthman or ties to Ali, massacred numerous tribesmen of the Hamdan and townspeople from [[Sana'a]] and [[Ma'rib]]. Before he could continue his campaign in [[Hadhramawt]], he withdrew upon the approach of a Kufan relief force.{{sfn|Madelung|1997|pp=304–305}} News of Busr's actions in Arabia spurred Ali's troops to rally behind his planned campaign against Mu'awiya,{{sfn|Madelung|1997|p=307}} but the expedition was aborted as a result of [[Assassination of Ali|Ali's assassination]] by a Kharijite in January 661.{{sfn|Wellhausen|1927|pp=102–103}}

==Caliphate==
===Accession===
After Ali was killed, Mu'awiya left al-Dahhak ibn Qays in charge of Syria and led his army toward Kufa, where Ali's son [[Hasan ibn Ali|Hasan]] had been nominated as his successor.{{sfn|Donner|2012|p=166}}{{sfn|Madelung|1997|p=317}} He successfully bribed [[Ubayd Allah ibn Abbas]], the commander of Hasan's vanguard, to desert his post and sent envoys to negotiate with Hasan.{{sfn|Madelung|1997|pp=320, 322}} In return for a financial settlement, [[Hasan ibn Ali#Conflict with Mu'awiya|Hasan abdicated]] and Mu'awiya entered Kufa in July or September 661 and was recognized as caliph. This year is considered by a number of the early Muslim sources as 'the year of unity' and is generally regarded as the start of Mu'awiya's caliphate.{{sfn|Hinds|1993|p=265}}{{sfn|Marsham|2013|p=93}}

Before and/or after Ali's death, Mu'awiya received oaths of allegiance in one or two formal ceremonies in Jerusalem, the first in late 660 or early 661 and the second in July 661.{{sfn|Marsham|2013|p=96}} The 10th-century Jerusalemite geographer [[al-Maqdisi]] holds that Mu'awiya had further developed a mosque originally built by Caliph Umar on the [[Temple Mount]], the precursor of the [[Qibli Mosque|Jami Al-Aqsa]], and received his formal oaths of allegiance there.{{sfn|Marsham|2013|pp=97, 100}} According to the earliest extant source about Mu'awiya's accession in Jerusalem, the near-contemporaneous [[Maronite Chronicles]], composed by an anonymous [[Syriac Christianity|Syriac]] author, Mu'awiya received the pledges of the tribal chieftains and then prayed at [[Golgotha]] and the [[Tomb of the Virgin Mary]] in [[Gethsemane]], both adjacent to the Temple Mount.{{sfn|Marsham|2013|pp=87, 89, 101}} The Maronite Chronicles also maintain that Mu'awiya "did not wear a crown like other kings in the world".{{sfn|Marsham|2013|pp=94, 106}}

===Domestic rule and administration===

There is little information in the early Muslim sources about Mu'awiya's rule in Syria, the center of his caliphate.{{sfn|Wellhausen|1927|p=131}}{{sfn|Kennedy|2004|p=86}} He established his court in Damascus and moved the caliphal treasury there from Kufa.{{sfn|Wellhausen|1927|pp=59–60, 131}} He relied on his Syrian tribal soldiery,{{sfn|Wellhausen|1927|p=131}} numbering about 100,000 men,{{sfn|Kennedy|2001|p=20}} increasing their pay at the expense of the Iraqi garrisons,{{sfn|Wellhausen|1927|p=131}} also about 100,000 soldiers combined.{{sfn|Kennedy|2001|p=20}} The highest stipends were paid on an inheritable basis to 2,000 nobles of the Quda'a and Kinda tribes, the core components of his support base, who were further awarded the privilege of consultation for all major decisions and the rights to veto or propose measures.{{sfn|Hinds|1993|p=267}}{{sfn|Crone|1994|p=44}} The respective leaders of the Quda'a and the Kinda, the Kalbite chief [[Ibn Bahdal]] and the Homs-based Shurahbil, formed part of his Syrian inner circle along with the Qurayshites [[Abd al-Rahman ibn Khalid]], son of the distinguished commander [[Khalid ibn al-Walid]], and [[Al-Dahhak ibn Qays al-Fihri|al-Dahhak ibn Qays]].{{sfn|Kennedy|2004|pp=86–87}}

Mu'awiya is credited by the early Muslim sources for establishing {{transliteration|ar|[[divan|diwan]]s}} (government departments) for correspondences ({{transliteration|ar|rasa'il}}), chancellery ({{transliteration|ar|khatam}}) and the postal route ({{transliteration|ar|barid}}).{{sfn|Hinds|1993|p=267}} According to al-Tabari, following an assassination attempt by the Kharijite al-Burak ibn Abd Allah on Mu'awiya while he was praying in the mosque of Damascus in 661, Mu'awiya established a caliphal {{transliteration|ar|[[haras (unit)|haras]]}} (personal guard) and {{transliteration|ar|[[shurta]]}} (select troops) and the {{transliteration|ar|[[maqsura]]}} (reserved area) within mosques.{{sfn|Hawting|1996|p=223}}{{sfn|Kennedy|2001|p=13}} The caliph's treasury was largely dependent on the tax revenues of Syria and income from the crown lands that he confiscated in Iraq and Arabia. He also received the customary fifth of the war booty acquired by his commanders during expeditions.{{sfn|Hinds|1993|p=267}} In the Jazira, Mu'awiya coped with the tribal influx, which spanned previously established groups such as the [[Banu Sulaym|Sulaym]], newcomers from the [[Mudar]] and [[Rabi'a ibn Nizar|Rabi'a]] confederations and civil war refugees from Kufa and Basra, by administratively detaching the military district of [[Jund Qinnasrin|Qinnasrin–Jazira]] from Homs, according to the 8th-century historian [[Sayf ibn Umar]].{{sfn|Hinds|1993|p=266}}{{sfn|Crone|1994|p=45, note 239}} However, al-Baladhuri attributes this change to Mu'awiya's successor [[Yazid I]] ({{reign|680|683}}).{{sfn|Hinds|1993|p=266}}

Syria retained its Byzantine-era bureaucracy, which was staffed by Christians including the head of the tax administration, [[Sarjun ibn Mansur]].{{sfn|Kennedy|2004|p=87}} The latter had served Mu'awiya in the same capacity before his attainment of the caliphate,{{sfn|Sprengling|1939|p=182}} and Sarjun's father was the likely holder of the office under Emperor [[Heraclius]] ({{reign|610|641}}).{{sfn|Kennedy|2004|p=87}} Mu'awiya was tolerant toward Syria's native Christian majority.{{sfn|Humphreys|2006|pp=102–103}} In turn, the community was generally satisfied with his rule, under which their conditions were at least as favorable as under the Byzantines.{{sfn|Wellhausen|1927|p=134}} Mu'awiya attempted to mint his own coins, but the new currency was rejected by the Syrians as it omitted the symbol of the cross.{{sfn|Hawting|2000|p=842}} The sole epigraphic attestation to Mu'awiya's rule in Syria, a Greek inscription dated to 663 discovered at the hot springs of [[Hamat Gader]] near the [[Sea of Galilee]],{{sfn|Foss|2016|p=83}} refers to the caliph as ''Abd Allah Mu'awiya, amir al-mu'minin'' ("God's Servant Mu'awiya, commander of the faithful"; the caliph's name is preceded by a cross) and credits him for restoring Roman-era [[thermae|bath facilities]] for the benefit of the sick. According to the historian [[Yizhar Hirschfeld]], "by this deed, the new caliph sought to please" his Christian subjects.{{sfn|Hirschfeld|1987|p=107}} The caliph often spent his winters at his [[Sinnabra]] palace near the Sea of Galilee.{{sfn|Hasson|1982|p=99}} Mu'awiya was also credited with ordering the restoration of [[Edessa]]'s church after it was ruined in an earthquake in 679.{{sfn|Hoyland|1999|p=159}} He demonstrated a keen interest in Jerusalem.{{sfn|Elad|1999|p=23}} Although archaeological evidence is lacking, there are indications in medieval literary sources that a rudimentary mosque on the Temple Mount existed as early as Mu'awiya's time or was built by him.{{sfn|Elad|1999|p=33}}{{efn|The Christian pilgrim [[Arculf]] visited [[Jerusalem]] between 679 and 681 and noted that a makeshift Muslim prayer house built of beams and clay with a capacity for 3,000 worshipers had been erected on the Temple Mount, while a Jewish {{transliteration|he|[[midrash]]}} holds that Mu'awiya rebuilt the Temple Mount's walls. The mid-10th-century Arabic chronicler [[Ibn Tahir]] explicitly states that Mu'awiya built a mosque on the site.{{sfn|Elad|1999|pp=23–24, 33}}}}

===Governance in the provinces===
Mu'awiya's primary internal challenge was overseeing a Syria-based government that could reunite the politically and socially fractured Caliphate and assert authority over the tribes which formed its armies.{{sfn|Hinds|1993|p=266}} He applied indirect rule to the Caliphate's provinces, appointing governors with full civil and military authority.{{sfn|Hinds|1993|pp=266–267}} Although in principle governors were obliged to forward surplus tax revenues to the caliph,{{sfn|Hinds|1993|p=266}} in practice most of the surplus was distributed among the provincial garrisons and Damascus received a negligible share.{{sfn|Hinds|1993|p=267}}{{sfn|Kennedy|2004|p=83}} During Mu'awiya's caliphate, the governors relied on the {{transliteration|ar|ashraf}} (tribal chieftains), who served as intermediaries between the authorities and the tribesmen in the garrisons.{{sfn|Hinds|1993|p=266}} Mu'awiya's statecraft was likely inspired by his father, who utilized his wealth to establish political alliances.{{sfn|Kennedy|2004|p=83}} The caliph generally preferred bribing his opponents over direct confrontation. In the summation of Kennedy, Mu'awiya ruled by "making agreements with those who held power in the provinces, by building up the power of those who were prepared to co-operate with him and by attaching as many important and influential figures to his cause as possible".{{sfn|Kennedy|2004|p=83}}

====Iraq and the east====
Challenges to central authority in general, and to Mu'awiya's rule in particular, were most acute in Iraq, where divisions were rife between the {{transliteration|ar|ashraf}} upstarts and the nascent Muslim elite, the latter of which was further divided between Ali's partisans and the Kharijites.{{sfn|Kennedy|2004|pp=83–84}} Mu'awiya's ascent signaled the rise of the Kufan {{transliteration|ar|ashraf}} represented by Ali's erstwhile backers al-Ash'ath ibn Qays and Jarir ibn Abd Allah, at the expense of Ali's old guard represented by [[Hujr ibn Adi]] and [[Ibrahim ibn al-Ashtar|Ibrahim]], the son of Ali's leading aide [[Malik al-Ashtar]]. Mu'awiya's initial choice to govern Kufa in 661 was [[al-Mughira ibn Shu'ba]], who possessed considerable administrative and military experience in Iraq and was highly familiar with the region's inhabitants and issues. Under his nearly decade-long administration, al-Mughira maintained peace in the city, overlooked transgressions that did not threaten his rule, allowed the Kufans to keep possession of the lucrative Sasanian crown lands in the [[Jibal]] district and, unlike under past administrations, consistently and timely paid the garrison's stipends.{{sfn|Kennedy|2004|p=84}}

In Basra, Mu'awiya reappointed his Abd Shams kinsman [[Abd Allah ibn Amir]], who had served in the office under Uthman.{{sfn|Kennedy|2004|pp=84–85}} During Mu'awiya's reign, Ibn Amir recommenced expeditions into [[Sistan]], reaching as far as [[Kabul]]. He was unable to maintain order in Basra, where there was growing resentment toward the distant campaigns. Consequently, Mu'awiya replaced Ibn Amir with [[Ziyad ibn Abihi]] in 664 or 665.{{sfn|Kennedy|2004|p=85}} The latter had been the longest of Ali's loyalists to withhold recognition of Mu'awiya's caliphate and had barricaded himself in the [[Istakhr]] fortress in [[Fars province|Fars]].{{sfn|Wellhausen|1927|p=120}} Busr had threatened to execute three of Ziyad's young sons in Basra to force his surrender, but Ziyad was ultimately persuaded by al-Mughira, his mentor, to submit to Mu'awiya's authority in 663.{{sfn|Wellhausen|1927|p=121}} In a controversial step that secured the loyalty of the fatherless Ziyad, whom the caliph viewed as the most capable candidate to govern Basra,{{sfn|Kennedy|2004|p=85}} Mu'awiya adopted him as his paternal half-brother, to the protests of his own son Yazid, Ibn Amir and his Umayyad kinsmen in the Hejaz.{{sfn|Wellhausen|1927|p=121}}{{sfn|Hasson|2002|p=520}}

Following al-Mughira's death in 670, Mu'awiya attached Kufa and its dependencies to Ziyad's Basran governorship, making him the caliph's virtual viceroy over the eastern half of the Caliphate.{{sfn|Kennedy|2004|p=85}} Ziyad tackled Iraq's core economic problem of overpopulation in the garrison cities and the consequent scarcity of resources by reducing the number of troops on the payrolls and dispatching 50,000 Iraqi soldiers and their families to settle [[Greater Khorasan|Khurasan]]. This also consolidated the previously weak and unstable Arab position in the Caliphate's easternmost province and enabled conquests toward [[Transoxiana]].{{sfn|Hinds|1993|p=266}} As part of his reorganization efforts in Kufa, Ziyad confiscated its garrison's crown lands, which thenceforth became the possession of the caliph.{{sfn|Hinds|1993|pp=266–267}} Opposition to the confiscations raised by Hujr ibn Adi,{{sfn|Hinds|1993|p=266}} whose pro-Alid advocacy had been tolerated by al-Mughira,{{sfn|Wellhausen|1927|p=124}} was violently suppressed by Ziyad.{{sfn|Hinds|1993|p=266}} Hujr and his retinue were sent to Mu'awiya for punishment and were executed on the caliph's orders, marking the first political execution in Islamic history and serving as a harbinger for future pro-Alid uprisings in Kufa.{{sfn|Hasson|2002|p=520}}{{sfn|Hawting|2000|p=41}} Ziyad died in 673 and his son [[Ubayd Allah ibn Ziyad|Ubayd Allah]] was appointed gradually by Mu'awiya to all of his father's former offices. In effect, by relying on al-Mughira and Ziyad and his sons, Mu'awiya franchised the administration of Iraq and the eastern Caliphate to members of the elite [[Thaqif]] clan, which had long-established ties to the Quraysh and were instrumental in the conquest of Iraq.{{sfn|Kennedy|2004|p=86}}

====Egypt====
In Egypt, Amr governed more as a partner of Mu'awiya than a subordinate until his death in 664.{{sfn|Kennedy|2004|p=87}} He was permitted to retain the surplus revenues of the province.{{sfn|Kennedy|1998|p=69}} The caliph ordered the resumption of Egyptian grain and oil shipments to Medina, ending the hiatus caused by the First Fitna.{{sfn|Foss|2009|p=268}} After Amr's death, Mu'awiya's brother [[Utba ibn Abi Sufyan|Utba]] ({{reign|664|665}}) and an early companion of Muhammad, [[Uqba ibn Amir]] ({{reign|665|667}}), successively served as governors before Mu'awiya appointed [[Maslama ibn Mukhallad al-Ansari]] in 667.{{sfn|Kennedy|1998|p=69}}{{sfn|Kennedy|2004|p=87}} Maslama remained governor for the duration of Mu'awiya's reign,{{sfn|Kennedy|2004|p=87}} significantly expanding Fustat and its mosque and boosting the city's importance in 674 by relocating Egypt's main shipyard to the nearby [[Roda Island]] from Alexandria due to the latter's vulnerability to Byzantine naval raids.{{sfn|Foss|2009|p=269}}

The Arab presence in Egypt was mostly limited to the central garrison at Fustat and the smaller garrison at Alexandria.{{sfn|Foss|2009|p=268}} The influx of Syrian troops brought by Amr in 658 and the Basran troops sent by Ziyad in 673 swelled Fustat's 15,000-strong garrison to 40,000 during Mu'awiya's reign.{{sfn|Foss|2009|p=268}} Utba increased the Alexandria garrison to 12,000 men and built a governor's residence in the city, whose Greek Christian population was generally hostile to Arab rule. When Utba's deputy in Alexandria complained that his troops were unable to control the city, Mu'awiya deployed a further 15,000 soldiers from Syria and Medina.{{sfn|Foss|2009|p=272}} The troops in Egypt were far less rebellious than their Iraqi counterparts, though elements in the Fustat garrison occasionally raised opposition to Mu'awiya's policies, culminating during Maslama's term with the widespread protest at Mu'awiya's seizure and allotment of crown lands in [[Fayyum]] to his son Yazid, which compelled the caliph to reverse his order.{{sfn|Foss|2009|pp=269–270}}

====Arabia====
Although revenge for Uthman's assassination had been the basis upon which Mu'awiya claimed the right to the caliphate, he neither emulated Uthman's empowerment of the Umayyad clan nor used them to assert his own power.{{sfn|Kennedy|2004|p=83}}{{sfn|Wellhausen|1927|p=135}} With minor exceptions, members of the clan were not appointed to the wealthy provinces nor the caliph's court, Mu'awiya largely limiting their influence to Medina, the old capital of the Caliphate where most of the Umayyads and the wider Qurayshite former aristocracy remained headquartered.{{sfn|Kennedy|2004|p=83}}{{sfn|Wellhausen|1927|pp=135–136}} The loss of political power left the Umayyads of Medina resentful toward Mu'awiya, who may have become wary of the political ambitions of the much larger Abu al-As branch of the clan—to which Uthman had belonged—under the leadership of [[Marwan ibn al-Hakam]].{{sfn|Bosworth|1991|pp=621–622}} The caliph attempted to weaken the clan by provoking internal divisions.{{sfn|Wellhausen|1927|p=136}} Among the measures taken was the replacement of Marwan from the governorship of Medina in 668 with another leading Umayyad, [[Sa'id ibn al-As]]. The latter was instructed to demolish Marwan's house, but refused and when Marwan was restored in 674, he also refused Mu'awiya's order to demolish Sa'id's house.{{sfn|Madelung|1997|p=345, note 90}} Mu'awiya dismissed Marwan once more in 678, replacing him with his own nephew, [[al-Walid ibn Utba ibn Abi Sufyan|al-Walid ibn Utba]].{{sfn|Madelung|1997|p=346}} Besides his own clan, Mu'awiya's relations with the [[Banu Hashim]] (the clan of Muhammad and Caliph Ali), the families of Muhammad's closest companions, the once-prominent Banu Makhzum, and the Ansar was generally characterized by suspicion or outright hostility.{{sfn|Wellhausen|1927|pp=136–137}}

Despite his relocation to Damascus, Mu'awiya remained fond of his original homeland and made known his longing for "the spring in [[Juddah]] ''[sic]'', the summer in Ta'if, [and] the winter in Mecca".{{sfn|Miles|1948|p=236}} He purchased several large tracts throughout Arabia and invested considerable sums to develop the lands for agricultural use. According to the Muslim literary tradition, in the plain of [[Mount Arafat|Arafat]] and the barren valley of Mecca he dug numerous wells and canals, constructed dams and dikes to protect the soil from seasonal floods, and built fountains and reservoirs. His efforts saw extensive grain fields and date palm groves spring up across Mecca's suburbs, which remained in this state until deteriorating during the [[Abbasid Caliphate|Abbasid]] era, which began in 750.{{sfn|Miles|1948|p=236}} In the [[al-Yamama|Yamama]] region in central Arabia, Mu'awiya confiscated from the [[Banu Hanifa]] the lands of Hadarim, where he employed 4,000 slaves, likely to cultivate its fields.{{sfn|Dixon|1971|p=170}} The caliph gained possession of estates in and near Ta'if which, together with the lands of his brothers Anbasa and Utba, formed a considerable cluster of properties.{{sfn|Miles|1948|p=238}}

One of the earliest known Arabic inscriptions from Mu'awiya's reign was found at a soil-conservation dam called Sayisad {{convert|32|km|sp=us}} east of Ta'if, which credits Mu'awiya for the dam's construction in 677 or 678 and asks God to give him victory and strength.{{sfn|Miles|1948|p=237}} Mu'awiya is also credited as the patron of a second dam called al-Khanaq {{convert|15|km|sp=us}} east of Medina, according to an inscription found at the site.{{sfn|Al-Rashid|2008|p=270}} This is possibly the dam between Medina and the gold mines of the Banu Sulaym tribe attributed to Mu'awiya by the historians al-Harbi (d. 898) and [[al-Samhudi]] (d. 1533).{{sfn|Al-Rashid|2008|pp=271, 273}}

===War with Byzantium===
[[File:Arab-Byzantine Wars during Muawiya's governorship and caliphate.png|upright=1.5|thumb|Map showing the raids, battles and naval engagements between the Arab Caliphate and [[Byzantine Empire under the Heraclian dynasty|Byzantine]] during Mu'awiya's governorship of Syria (640–661) and Mu'awiya's [[caliphate]] (661–680).]]
Mu'awiya possessed more personal experience than any other caliph fighting the Byzantines,{{sfn|Kaegi|1995|p=247}} the principal external threat to the Caliphate,{{sfn|Hinds|1993|p=265}} and pursued the war against the Empire more energetically and continuously than his successors.{{sfn|Wellhausen|1927|p=115}} The First Fitna caused the Arabs to lose control over Armenia to native, pro-Byzantine princes, but in 661 Habib ibn Maslama re-invaded the region.{{sfn|Kaegi|1995|p=185}} The following year, Armenia became a tributary of the Caliphate and Mu'awiya recognized the Armenian prince [[Grigor Mamikonian]] as its commander.{{sfn|Kaegi|1995|p=185}} Not long after the civil war, Mu'awiya broke the truce with Byzantium,{{sfn|Jankowiak|2013|p=273}} and on a near-annual or bi-annual basis the caliph engaged his Syrian troops in raids across the [[Al-Awasim|mountainous Anatolian frontier]],{{sfn|Kennedy|2004|p=87}} the buffer zone between the Empire and the Caliphate.{{sfn|Kaegi|1995|pp=244–245, 247}} At least until Abd al-Rahman ibn Khalid's death in 666, Homs served as the principal marshaling point for the offensives, and afterward Antioch served this purpose as well.{{sfn|Kaegi|1995|pp=245, 247}} The bulk of the troops fighting on the Anatolian and Armenian fronts hailed from the tribal groups that arrived from Arabia during and after the conquest.{{sfn|Humphreys|2006|p=61}} During his caliphate, Mu'awiya continued his past efforts to resettle and fortify the Syrian port cities.{{sfn|Hinds|1993|p=265}} Due to the reticence of Arab tribesmen to inhabit the coastlands, in 663 Mu'awiya moved Persian civilians and personnel that he had previously settled in the Syrian interior into Acre and Tyre, and transferred [[Asawira]], elite Persian soldiers, from Kufa and Basra to the garrison at Antioch.{{sfn|Jandora|1986|p=111}}{{sfn|Kennedy|2001|p=12}} A few years later, Mu'awiya settled [[Apamea, Syria|Apamea]] with 5,000 [[Slavs]] who had defected from the Byzantines during one of his forces' Anatolian campaigns.{{sfn|Jandora|1986|p=111}}

Based on the histories of [[al-Tabari]] (d. 923) and [[Agapius of Hierapolis]] (d. 941), the first raid of Mu'awiya's caliphate occurred in 662 or 663, during which his forces inflicted a heavy defeat on a Byzantine army with numerous [[Patrician (ancient Rome)#Late Roman and Byzantine period|patrician]]s slain. In the next year a raid led by Busr reached Constantinople and in 664 or 665, Abd al-Rahman ibn Khalid raided [[Şebinkarahisar|Koloneia]] in northeastern Anatolia. In the late 660s, Mu'awiya's forces attacked [[Antioch of Pisidia]] or [[Antiochia ad Cragum|Antioch of Isauria]].{{sfn|Jankowiak|2013|p=273}} Following the death of Constans II in July 668, Mu'awiya oversaw an increasingly aggressive policy of naval warfare against the Byzantines.{{sfn|Hinds|1993|p=265}} According to the early Muslim sources, raids against the Byzantines peaked between 668 and 669.{{sfn|Jankowiak|2013|p=273}} In each of those years there occurred six ground campaigns and a major naval campaign, the first by an Egyptian and Medinese fleet and the second by an Egyptian and Syrian fleet.{{sfn|Jankowiak|2013|pp=273–274}} The culmination of the campaigns was an assault on Constantinople, but the chronologies of the Arabic, Syriac, and Byzantine sources are contradictory. The traditional view by modern historians is of a [[Siege of Constantinople (674–678)|great series of naval-borne assaults]] against Constantinople in {{circa|674–678}}, based on the history of the Byzantine chronicler [[Theophanes the Confessor]] (d. 818).{{sfn|Jankowiak|2013|pp=303–304}}

However, the dating and the very historicity of this view has been challenged; the Oxford scholar [[James Howard-Johnston]] considers that no siege of Constantinople took place, and that the story was inspired by the [[Siege of Constantinople (717–718)|actual siege]] a generation later.{{sfn|Howard-Johnston|2010|pp=303–304}} The historian Marek Jankowiak on the other hand, in a revisionist reconstruction of the events reliant on the Arabic and Syriac sources, asserts that the assault came earlier than what is reported by Theophanes, and that the multitude of campaigns that were reported during 668–669 represented the coordinated efforts by Mu'awiya to conquer the Byzantine capital.{{sfn|Jankowiak|2013|p=290}} Al-Tabari reports that Mu'awiya's son Yazid led a campaign against Constantinople in 669 and [[Ibn Abd al-Hakam]] reports that the Egyptian and Syrian navies joined the assault, led by Uqba ibn Amir and [[Fadala ibn Ubayd]] respectively.{{sfn|Jankowiak|2013|pp=267, 274}} According to Jankowiak, Mu'awiya likely ordered the invasion during an opportunity presented by the rebellion of the Byzantine Armenian general [[Saborios]], who formed a pact with the caliph, in spring 667. The caliph dispatched an army under Fadala, but before it could be joined by the Armenians, Saborios died. Mu'awiya then sent reinforcements led by Yazid who led the Arab army's invasion in the summer.{{sfn|Jankowiak|2013|pp=303–304}} An Arab fleet reached the [[Sea of Marmara]] by autumn, while Yazid and Fadala, having raided [[Chalcedon]] through the winter, besieged Constantinople in spring 668, but due to famine and disease, lifted the siege in late June. The Arabs continued their campaigns in Constantinople's vicinity before withdrawing to Syria most likely in late 669.{{sfn|Jankowiak|2013|pp=304, 316}}

In 669, Mu'awiya's navy raided as far as Sicily. The following year, the wide-scale fortification of Alexandria was completed.{{sfn|Hinds|1993|p=265}} While the histories of al-Tabari and al-Baladhuri report that Mu'awiya's forces captured Rhodes in 672–674 and colonized the island for seven years before withdrawing during the reign of Yazid I, the modern historian [[Clifford Edmund Bosworth]] casts doubt on these events and holds that the island was only raided by Mu'awiya's lieutenant [[Junada ibn Abi Umayya al-Azdi]] in 679 or 680.{{sfn|Bosworth|1996|pp=159–160}} Under Emperor [[Constantine IV]] ({{reign|668|685}}), the Byzantines began a counteroffensive against the Caliphate, first raiding Egypt in 672 or 673,{{sfn|Jankowiak|2013|p=316}} while in winter 673, Mu'awiya's admiral Abd Allah ibn Qays led a large fleet that raided [[Smyrna]] and the coasts of Cilicia and Lycia.{{sfn|Jankowiak|2013|p=318}} The Byzantines landed a major victory against an Arab army and fleet led by Sufyan ibn Awf, possibly at [[Sillyon]], in 673 or 674.{{sfn|Jankowiak|2013|pp=278–279, 316}} The next year, Abd Allah ibn Qays and Fadala landed in Crete and in 675 or 676, a Byzantine fleet assaulted Maraclea, killing the governor of Homs.{{sfn|Jankowiak|2013|p=316}}

In 677, 678 or 679, according to Theophanes, Mu'awiya sued for peace with Constantine IV, possibly as a result of the destruction of his fleet or the Byzantines' deployment of the [[Mardaites]] in the Syrian littoral during that time.{{sfn|Stratos|1978|p=46}} A thirty-year treaty was concluded, obliging the Caliphate to pay an annual tribute of 3,000 gold coins, 50 horses and 30 slaves, and withdraw their troops from the forward bases they had occupied on the Byzantine coast.{{sfn|Lilie|1976|pp=81–82}} But other Byzantine and Islamic sources make no mention of this treaty.{{sfn|Jankowiak|2013|p=254}} Although the Muslims did not achieve any permanent territorial gains in Anatolia during Mu'awiya's career, the frequent raids provided Mu'awiya's Syrian troops with war spoils and tribute, which helped ensure their continued allegiance, and sharpened their combat skills.{{sfn|Kennedy|2004|p=88}} Moreover, Mu'awiya's prestige was boosted and the Byzantines were precluded from any concerted campaigns against Syria.{{sfn|Kaegi|1995|pp=247–248}}

====Conquest of central North Africa====
[[File:Arabische Eroberung 2.jpg|thumb|upright=1.75|alt=A map of northern Africa, southern Europe and western and central Asia with different color shades denoting the stages of expansion of the caliphate|A map depicting growth of the Caliphate. During the reign of Mu'awiya, the Muslims conquered the region of [[Ifriqiya]] (central [[North Africa]]; shaded in purple)]]

Although the Arabs had not advanced beyond [[Cyrenaica]] since the 640s other than periodic raids, the expeditions against [[Exarchate of Africa|Byzantine North Africa]] were renewed during Mu'awiya's reign.{{sfn|Kennedy|2007|pp=207–208}} In 665 or 666 Ibn Hudayj led an army which raided [[Byzacena]] (southern district of [[Byzantine Africa]]) and [[Gabes]] and temporarily captured [[Bizerte]] before withdrawing to Egypt. The following year Mu'awiya dispatched Fadala and [[Ruwayfi ibn Thabit]] to raid the commercially valuable island of [[Djerba]].{{sfn|Kaegi|2010|p=12}} Meanwhile, in 662 or 667, [[Uqba ibn Nafi]], a Qurayshite commander who had played a key role in the Arabs' capture of Cyrenaica in 641, reasserted Muslim influence in the [[Fezzan]] region, capturing the [[Zawila]] oasis and the [[Garamantes]] capital of [[Germa]].{{sfn|Christides|2000|p=789}} He may have raided as far south as [[Kaouar|Kawar]] in modern-day Niger.{{sfn|Christides|2000|p=789}}

Uqba served as Mu'awiya's lieutenant governor over North Africa until the caliph dismissed him in 673.]]

The struggle over the succession of Constantine IV drew Byzantine focus away from the African front.{{sfn|Kaegi|2010|p=13}} In 670, Mu'awiya appointed Uqba as Egypt's deputy governor over the North African lands under Arab control west of Egypt. At the head of a 10,000-strong force, Uqba commenced his expedition against the territories west of Cyrenaica.{{sfn|Kennedy|2007|p=209}} As he advanced, his army was joined by Islamized [[Laguatan|Luwata Berbers]] and their combined forces conquered [[Ghadamis]], [[Gafsa]] and the [[Djerid|Jarid]].{{sfn|Christides|2000|p=789}}{{sfn|Kennedy|2007|p=209}} In the last region he established a permanent Arab garrison town called [[Kairouan]], at a relatively safe distance from [[Carthage]] and the coastal areas, which had remained under Byzantine control, to serve as a base for further expeditions. It also aided Muslim conversion efforts among the [[Berbers|Berber]] tribes that dominated the surrounding countryside.{{sfn|Christides|2000|p=790}}

Mu'awiya dismissed Uqba in 673, probably out of concern that he would form an independent power base in the lucrative regions that he had conquered. The new Arab province, [[Ifriqiya]] (modern-day Tunisia), remained subordinate to the governor of Egypt, who sent his {{transliteration|ar|[[mawla]]}} (non-Arab, Muslim freedman) [[Abu al-Muhajir Dinar]] to replace Uqba, who was arrested and transferred to Mu'awiya's custody in Damascus. Abu al-Muhajir continued the westward campaigns as far as [[Tlemcen]] and defeated the Awraba Berber chief [[Kusaila|Kasila]], who subsequently embraced Islam and joined his forces.{{sfn|Christides|2000|p=790}} In 678, a treaty between the Arabs and the Byzantines ceded Byzacena to the Caliphate, while forcing the Arabs to withdraw from the northern parts of the province.{{sfn|Kaegi|2010|p=13}} After Mu'awiya's death, his successor Yazid reappointed Uqba, Kasila defected and a Byzantine–Berber alliance ended Arab control over Ifriqiya,{{sfn|Christides|2000|p=790}} which was not reestablished until the reign of Caliph [[Abd al-Malik ibn Marwan]] ({{reign|685|705}}).{{sfn|Kennedy|2007|p=217}}

===Nomination of Yazid as successor===
In a move unprecedented in Islamic politics, Mu'awiya nominated his own son, Yazid, as his successor.{{sfn|Lewis|2002|p=67}} The caliph likely held ambitions for his son's succession over a considerable period.{{sfn|Wellhausen|1927|p=146}} In 666, he allegedly had his governor in Homs, Abd al-Rahman ibn Khalid, poisoned to remove him as a potential rival to Yazid.{{sfn|Hinds|1991|pp=139–140}} The Syrian Arabs, with whom Abd al-Rahman ibn Khalid was popular, had viewed the governor as the caliph's most suitable successor by dint of his military record and descent from Khalid ibn al-Walid.{{sfn|Madelung|1997|pp=339–340}}{{efn|The claim that Mu'awiya had [[Abd al-Rahman ibn Khalid]] poisoned by his Christian doctor Ibn Uthal is found in the medieval Islamic histories of [[al-Mada'ini]], [[al-Tabari]], al-Baladhuri and [[Mus'ab ibn al-Zubayr]], among others{{sfn|Madelung|1997|pp=340–342}}{{sfn|Hinds|1991|p=139}} and is accepted by historian [[Wilferd Madelung]],{{sfn|Madelung|1997|pp=340–342}} while historians [[Martin Hinds]] and [[Julius Wellhausen]] consider Mu'awiya's role in the affair as an allegation of the early Muslim sources.{{sfn|Hinds|1991|p=139}}{{sfn|Wellhausen|1927|p=137}} The Orientalists [[Michael Jan de Goeje]] and [[Henri Lammens]] dismiss the claim;{{sfn|de Goeje|1911|p=28}}{{sfn|Gibb|1960|p=85}} the former called it an "absurdity" and "incredible" that Mu'awiya "would have deprived himself of one of his best men" and the more likely scenario was that Abd al-Rahman ibn Khalid had been ill and Mu'awiya attempted to have him treated by Ibn Uthal, who was unsuccessful. De Goeje further doubts the credibility of the reports as they originated in [[Medina]], the home of his [[Banu Makhzum]] clan, rather than [[Homs]] where Abd al-Rahman ibn Khalid had died.{{sfn|de Goeje|1911|p=28}}}}

It was not until the latter half of his reign that Mu'awiya publicly declared Yazid heir apparent, though the early Muslim sources offer divergent details about the timing and location of the events relating to the decision.{{sfn|Marsham|2013|p=90}} The accounts of [[al-Mada'ini]] (752–843) and [[Ibn al-Athir]] (1160–1232) agree that al-Mughira was the first to suggest that Yazid be acknowledged as Mu'awiya's successor and that Ziyad supported the nomination with the caveat that Yazid abandon impious activities which could arouse opposition from the Muslim polity.{{sfn|Wellhausen|1927|pp=141, 143}} According to al-Tabari, Mu'awiya publicly announced his decision in 675 or 676 and demanded oaths of allegiance be given to Yazid.{{sfn|Morony|1987|p=183}} Ibn al-Athir alone relates that delegations from all the provinces were summoned to Damascus where Mu'awiya lectured them on his rights as ruler, their duties as subjects and Yazid's worthy qualities, which was followed by the calls of al-Dahhak ibn Qays and other courtiers that Yazid be recognized as the caliph's successor. The delegates lent their support, with the exception of the senior Basran nobleman [[al-Ahnaf ibn Qays]], who was ultimately bribed into compliance.{{sfn|Wellhausen|1927|p=142}} [[Al-Mas'udi]] (896–956) and al-Tabari do not mention provincial delegations other than a Basran embassy led by Ubayd Allah ibn Ziyad in 678–679 or 679–680, respectively, which recognized Yazid.{{sfn|Wellhausen|1927|pp=143–144}}

According to Hinds, in addition to Yazid's nobility, age and sound judgement, "most important of all" was his connection to the Kalb. The Kalb-led Quda'a confederation was the foundation of Sufyanid rule and Yazid's succession signaled the continuation of this alliance.{{sfn|Hinds|1993|p=267}} In nominating Yazid, the son of the Kalbite Maysun, Mu'awiya bypassed his older son Abd Allah from his Qurayshite wife Fakhita.{{sfn|Hawting|2002|p=309}} Although support from the Kalb and the Quda'a was guaranteed, Mu'awiya exhorted Yazid to widen his tribal support base in Syria. As the Qaysites were the predominant element in the northern frontier armies, Mu'awiya's appointment of Yazid to lead the war efforts with Byzantium may have served to foster Qaysite support for his nomination.{{sfn|Marsham|2013|pp=90–91}} Mu'awiya's efforts to that end were not entirely successful as reflected in a line by a Qaysite poet: "we will never pay allegiance to the son of a Kalbi woman [i.e. Yazid]".{{sfn|Marsham|2013|p=91}}{{sfn|Crone|1994|p=45}}

In Medina, Mu'awiya's distant kinsmen Marwan ibn al-Hakam, Sa'id ibn al-As and Ibn Amir accepted Mu'awiya's succession order, albeit disapprovingly.{{sfn|Madelung|1997|pp=342–343}} Most opponents of Mu'awiya's order in Iraq and among the Umayyads and Quraysh of the Hejaz were ultimately threatened or bribed into acceptance.{{sfn|Kennedy|2004|p=88}} The remaining principle opposition emanated from [[Husayn ibn Ali]], [[Abd Allah ibn al-Zubayr]], [[Abd Allah ibn Umar ibn al-Khattab|Abd Allah ibn Umar]] and [[Abd al-Rahman ibn Abi Bakr]], all prominent Medina-based sons of earlier caliphs or close companions of Muhammad.{{sfn|Donner|2012|p=177}} As they possessed the nearest claims to the caliphate, Mu'awiya was determined to obtain their recognition.{{sfn|Wellhausen|1927|pp=145–146}}{{sfn|Hawting|2000|p=43}} According to the historian [[Awana ibn al-Hakam]] (d. 764), before his death, Mu'awiya ordered certain measures to be taken against them, entrusting these tasks to his loyalists al-Dahhak ibn Qays and [[Muslim ibn Uqba]].{{sfn|Wellhausen|1927|p=144–145}}

Mu'awiya died from an illness in Damascus in Rajab 60 [[Anno Hegirae|AH]] (April or May 680 CE), at around the age of 80.{{sfn|Hinds|1993|p=264}}{{sfn|Morony|1987|p=210, 212–213}} The medieval accounts vary regarding the specific date of his death, with [[Hisham ibn al-Kalbi]] (d. 819) placing it on 7 April, al-Waqidi on 21 April and al-Mada'ini on 29 April.{{sfn|Morony|1987|p=210}} Yazid, who was away from Damascus at the time of his father's death,{{sfn|Morony|1987|pp=209, 213–214}} is held by [[Abu Mikhnaf]] (d. 774) to have succeeded him on 7 April, while the [[Nestorian]] chronicler [[Elijah of Nisibis|Elias of Nisibis]] (d. 1046) says it occurred on 21 April.{{sfn|Wellhausen|1927|p=139}} In his last testament, Mu'awiya told his family "Fear God, Almighty and Great, for God, praise Him, protects whoever fears Him, and there is no protector for one who does not fear God".{{sfn|Morony|1987|p=213}} He was buried next to the [[Bab al-Saghir]] gate of the city and the funeral prayers were led by al-Dahhak ibn Qays, who mourned Mu'awiya as the "stick of the Arabs and the blade of the Arabs, by means of whom God, Almighty and Great, cut off strife, whom He made sovereign over mankind, by means of whom he conquered countries, but now he has died".{{sfn|Morony|1987|pp=213–214}}

Mu'awiya's grave was a visitation site as late as the 10th century. Al-Mas'udi holds that a mausoleum was built over the grave and was open to visitors on Mondays and Thursdays. [[Ibn Taghribirdi]] asserts that [[Ahmad ibn Tulun]], the autonomous 9th-century ruler of Egypt and Syria, erected a structure on the grave in 883 or 884 and employed members of the public to regularly recite the Qur'an and light candles around the tomb.{{sfn|Grabar|1966|p=18}}

==Assessment and legacy==
Like Uthman, Mu'awiya adopted the title {{transliteration|ar|khalifat Allah}} ('deputy of God'), instead of {{transliteration|ar|khalifat rasul Allah}} ('deputy of the messenger of God'), the title used by the other caliphs who preceded him.{{sfn|Crone|Hinds|2003|pp=6–7}} The title may have implied political as well as religious authority and divine sanctioning.{{sfn|Hinds|1993|p=267}} He is reported by al-Baladhuri to have said "The earth belongs to God and I am the deputy of God".{{sfn|Crone|Hinds|2003|p=6}} Nevertheless, whatever the absolutist connotations the title may have had, Mu'awiya evidently did not impose this religious authority. Instead, he governed indirectly like a supra-tribal chief using alliances with provincial {{transliteration|ar|ashraf}}, his personal skills, persuasive power, and wit.{{sfn|Hinds|1993|p=267}}{{sfn|Humphreys|2006|p=93}}

Apart from his war with Ali, he did not deploy his Syrian troops domestically, and often used monetary gifts as a tool to avoid conflict.{{sfn|Kennedy|2004|p=83}} In [[Julius Wellhausen]]'s assessment, Mu'awiya was an accomplished diplomat "allowing matters to ripen of themselves, and only now and then assisting their progress".{{sfn|Wellhausen|1927|pp=137–138}} He further states that Mu'awiya had the ability to identify and employ the most talented men at his service and made even those whom he distrusted work for him.{{sfn|Wellhausen|1927|pp=137–138}}

In the view of the historian [[Patricia Crone]], Mu'awiya's successful rule was facilitated by the tribal composition of Syria. There, the Arabs who formed his support base were distributed throughout the countryside and were dominated by a single confederation, the Quda'a. This was in contrast to Iraq and Egypt, where the diverse tribal composition of the garrison towns meant that the government had no cohesive support base and had to create a delicate balance between the opposing tribal groups. As evidenced by the disintegration of Ali's Iraqi alliance, maintaining this balance was untenable. In her view, Mu'awiya's taking advantage of the tribal circumstances in Syria prevented the dissolution of the Caliphate in the civil war.{{sfn|Crone|2003|p=30}} In the words of the orientalist [[Martin Hinds]], the success of Mu'awiya's style of governance is "attested by the fact that he managed to hold his kingdom together without ever having to resort to using his Syrian troops".{{sfn|Hinds|1993|p=267}}

In the long-term, Mu'awiya's system proved precarious and unviable.{{sfn|Hinds|1993|p=267}} Reliance on personal relations meant his government was dependent on paying and pleasing its agents instead of commanding them. This created a "system of indulgence", according to Crone.{{sfn|Crone|2003|p=33}} The governors became increasingly unaccountable and amassed personal wealth. The tribal balance on which he relied was insecure and a slight fluctuation would lead to factionalism and infighting.{{sfn|Crone|2003|p=33}} When Yazid became caliph, he continued his father's model. Controversial as his nomination had been, he had to face the rebellions of Husayn and Ibn al-Zubayr. Although he was able to defeat them with the help of his governors and the Syrian army, the system fractured as soon as he died in November 683. The provincial {{transliteration|ar|ashraf}} defected to Ibn al-Zubayr, as did the Qaysite tribes, who had migrated to Syria during Mu'awiya's reign and were opposed to the Quda'a confederation on whom Sufyanid power rested. Within a matter of months the authority of Yazid's successor, [[Mu'awiya II]], had become restricted to Damascus and its environs. Although the Umayyads, backed by the Quda'a, were able to reconquer the Caliphate after the [[Second Fitna|decade-long second civil war]], it was under the leadership of Marwan, founder of the new ruling Umayyad house, the Marwanids, and his son Abd al-Malik.{{sfn|Hawting|2002|p=310}} Having realized the weakness of Mu'awiya's model and lacking in his political skill, the Marwanids abandoned his system in favor of a more traditional form of governance where the caliph was the central authority.{{sfn|Kennedy|2004|p=98}} Nonetheless, the hereditary succession introduced by Mu'awiya became a permanent feature of many of the Muslim governments that followed.{{sfn|Kennedy|2016|p=34}}

Kennedy views the preservation of the Caliphate's unity as Mu'awiya's greatest achievement.{{sfn|Kennedy|2004|p=82}} Expressing a similar viewpoint, Mu'awiya's biographer [[R. Stephen Humphreys]] states that although maintaining the integrity of the Caliphate would have been an achievement on its own, Mu'awiya was intent on vigorously continuing the conquests that had been initiated by Abu Bakr and Umar. By creating a formidable navy, he made the Caliphate the dominant force in the eastern Mediterranean and the Aegean. Control of northeastern Iran was secured and the Caliphate's frontier was expanded in North Africa.{{sfn|Humphreys|2006|pp=112–113}} Madelung deems Mu'awiya a corruptor of the caliphal office, under whom the precedence in Islam ({{transliteration|ar|sabiqa}}), which was the determining factor in the choice of earlier caliphs, gave way to the might of the sword, the people became his subjects and he became the "absolute lord over their life and death".{{sfn|Madelung|1997|pp=326–327}} He strangled the communal spirit of Islam and used the religion as a tool of "social control, exploitation and military terrorization".{{sfn|Madelung|1997|pp=326–327}}

Mu'awiya was the first caliph whose name appeared on coins, inscriptions, or documents of the nascent Islamic empire.{{sfn|Hoyland|2015|p=98}} The inscriptions from his reign lacked any explicit reference to Islam or Muhammad and the only titles that appear are 'servant of God' and 'commander of the faithful'. This has led some modern historians to question Mu'awiya's commitment to Islam.{{efn|These include [[Fred M. Donner]], [[Yehuda D. Nevo]], [[Karl-Heinz Ohlig]], and [[Gerd R. Puin]].{{sfn|Hoyland|2015|p=266 n. 30}}}} They have proposed that he adhered to a non-confessional or indeterminate form of monotheism, or may have been a Christian. Asserting that the earliest Muslims did not see their faith as different from other monotheistic faiths, these historians see the earlier Medina-based caliphs in the same vein, but no public proclamations from their period exist. On the other hand, the historian [[Robert Hoyland]] notes that Mu'awiya gave a very Islamic challenge to the Byzantine emperor Constans to "deny [the divinity of] Jesus and turn to the Great God whom I worship, the God of our father Abraham" and speculates that Mu'awiya's tour of Christian sites in Jerusalem was done to demonstrate "the fact that he, and not the Byzantine emperor, was now God's representative on earth".{{sfn|Hoyland|2015|pp=135–136, 266 n. 30}}

===Early historical tradition===
The surviving Muslim histories originated in Abbasid-era Iraq.{{sfn|Hoyland|2015|p=233}} The compilers, the narrators from whom the stories were collected, and the overall public sentiment in Iraq were hostile to the Syria-based Umayyads,{{sfn|Hawting|2000|pp=16–17}} under whom Syria was a privileged province and Iraq was locally perceived as a Syrian colony.{{sfn|Kennedy|2016|p=34}} Moreover, the Abbasids, having overthrown the Umayyads in 750, saw them as illegitimate rulers and further tarnished their memory to enhance their own legitimacy. Abbasid caliphs like [[al-Saffah]], [[al-Ma'mun]], and [[al-Mu'tadid]] publicly condemned Mu'awiya and other Umayyad caliphs.{{sfn|Humphreys|2006|pp=3–6}} As such, the Muslim historical tradition is by and large anti-Umayyad.{{sfn|Hoyland|2015|p=233}} Nonetheless, in the case of Mu'awiya it portrays him in a relatively balanced manner.{{sfn|Hawting|2000|p=42}}

On the one hand, it portrays him as a successful ruler who implemented his will with persuasion instead of force.{{sfn|Hawting|2000|p=42}} It stresses his quality of {{transliteration|ar|hilm}}, which in his case meant mildness, slowness to anger, subtlety, and management of people by perceiving their needs and desires.{{sfn|Hinds|1993|p=267}}{{sfn|Humphreys|2006|p=119}} The historical tradition is rife with anecdotes of his political acumen and self-control. In one such anecdote, when inquired about allowing one of his courtiers to address him with arrogance, he remarked:{{sfn|Humphreys|2006|p=121}}
{{blockquote|I do not insert myself between the people and their tongue, so long as they do not insert themselves between us and our sovereignty.{{sfn|Humphreys|2006|p=121}}}}

The tradition presents him operating in the way of a traditional tribal sheikh who lacks absolute authority; summoning delegations ({{transliteration|ar|wufud}}) of tribal chiefs, and persuading them with flattery, arguments, and presents. This is exemplified in a saying attributed to him: "I never use my voice if I can use my money, never my whip if I can use my voice, never my sword if I can use my whip; but, if I have to use my sword, I will."{{sfn|Hawting|2000|p=42}}

On the other hand, the tradition also portrays him as a despot who perverted the caliphate into kingship. In the words of [[al-Ya'qubi]] (d. 898):{{sfn|Hawting|2000|p=42}}
{{blockquote|[Mu'awiya] was the first to have a bodyguard, police-force and chamberlains ... He had somebody walk in front of him with a spear, took alms out of the stipends and sat on a throne with the people below him ... He used forced labour for his building projects ... He was the first to turn this matter [the caliphate] into mere kingship.{{sfn|Hoyland|2015|p=134}}}}

Al-Baladhuri calls him the '[[Khosrow (word)|Khosrow]] of the Arabs' ({{transliteration|ar|Kisra al-Arab}}).{{sfn|Crone|Hinds|2003|p=115}} 'Khosrow' was used by the Arabs as a reference to Sasanian Persian monarchs in general, who the Arabs associated with worldly splendor and [[authoritarianism]], as opposed to the humility of Muhammad.{{sfn|Morony|1986|pp=184–185}} Mu'awiya was compared to these monarchs mainly because he appointed his son Yazid as the next caliph, which was viewed as a violation of the Islamic principle of {{transliteration|ar|shura}} and an introduction of dynastic rule on par with the Byzantines and Sasanians.{{sfn|Hawting|2000|p=42}}{{sfn|Crone|Hinds|2003|p=115}} The civil war that erupted after Mu'awiya's death is asserted to have been the direct consequence of Yazid's nomination.{{sfn|Hawting|2000|p=42}} In the Islamic tradition, Mu'awiya and the Umayyads are given the title of {{transliteration|ar|malik}} (king) instead of {{transliteration|ar|khalifa}} (caliph), though the succeeding Abbasids are recognized as caliphs.{{sfn|Lewis|2002|p=65}}

The contemporary non-Muslim sources generally present a benign image of Mu'awiya.{{sfn|Humphreys|2006|pp=102–103}}{{sfn|Hawting|2000|p=42}} The Greek historian Theophanes calls him a {{transliteration|el|protosymboulos}}, 'first among equals'.{{sfn|Hawting|2000|p=42}} According to Kennedy, the Nestorian Christian chronicler [[John bar Penkaye]] writing in the 690s "has nothing but praise for the first Umayyad caliph ... of whose reign he says 'the peace throughout the world was such that we have never heard, either from our fathers or from our grandparents, or seen that there had ever been any like it'".{{sfn|Kennedy|2007|p=349}}

===Muslim view===
In contrast to the four earlier caliphs, who are considered as models of piety and having governed with justice, Mu'awiya is not recognized as a rightly-guided caliph ({{transliteration|ar|khalifa rashid}}) by the Sunnis.{{sfn|Hoyland|2015|p=134}} He is seen as transforming the caliphate into a worldly and despotic kingship. His acquisition of the caliphate through the civil war and his institution of the hereditary succession by appointing his son Yazid as heir apparent are the principal charges made against him.{{sfn|Humphreys|2006|p=115}} Although Uthman and Ali had been highly controversial during the early period, religious scholars in the 8th and 9th centuries compromised in order to appease and absorb the [[Uthmaniyya|Uthmanid]] and pro-Alid factions. Uthman and Ali were thus regarded along with the first two caliphs as divinely guided, whereas Mu'awiya and those who came after him were viewed as oppressive tyrants.{{sfn|Hoyland|2015|p=134}} Nevertheless, the Sunnis accord him the status of a companion of Muhammad and consider him a scribe of the [[Qur'an]]ic revelation ({{transliteration|ar|katib al-wahi}}). On these accounts, he is also respected.{{sfn|Ende|1977|p=14}}{{sfn|Kohlberg|2020|p=105}} Some Sunnis defend his war against Ali holding that although he was in error, he acted according to his best judgment and had no evil intentions.{{sfn|Kohlberg|2020|p=105, note 136}}

Mu'awiya's war with Ali, whom the Shia hold as the true [[Succession to Muhammad|successor of Muhammad]], has made him a reviled figure in Shia Islam. According to the Shia, based on this alone Mu'awiya qualifies as an unbeliever, if he was a believer to begin with.{{sfn|Kohlberg|2020|p=105}} In addition, he is held responsible for the killing of a number of Muhammad's companions at Siffin, having ordered the cursing of Ali from the pulpit, appointing Yazid as his successor, who went on to kill Husayn at Karbala, executing the pro-Alid Kufan nobleman Hujr ibn Adi,{{sfn|Kohlberg|2020|pp=105–106}} and assassinating Hasan by poisoning.{{sfn|Pierce|2016|pp=83–85}} As such, he has been a particular target of Shia traditions. Some traditions hold him to have been born of an illegitimate relationship between Abu Sufyan's wife Hind and Muhammad's uncle [[Abbas ibn Abd al-Muttalib|Abbas]].{{sfn|Kohlberg|2020|p=103}} His conversion to Islam is held to be devoid of any conviction and to have been motivated by convenience after Muhammad conquered Mecca. On this basis he is given the title of {{transliteration|ar|taliq}} (freed slave of Muhammad). A number of hadiths are ascribed to Muhammad condemning Mu'awiya and his father Abu Sufyan in which he is called "an accursed man ({{transliteration|ar|la'in}}) son of an accursed man" and prophesying that he will die as an unbeliever.{{sfn|Kohlberg|2020|p=104}} Unlike the Sunnis, the Shia deny him the status of a companion{{sfn|Kohlberg|2020|p=104}} and also refute the Sunni claims that he was a scribe of the Qur'anic revelation.{{sfn|Kohlberg|2020|p=105}} Like other opponents of Ali, Mu'awiya is cursed in a ritual called {{transliteration|ar|[[tabarra]]}}, which is held by many Shia to be an obligation.{{sfn|Hyder|2006|p=82}}

Amid rising [[religious sectarianism]] among Muslims in the 10th century, while the Abbasid Caliphate was dominated by the [[Twelver Shia]] emirs of the [[Buyid dynasty]], the figure of Mu'awiya became a propaganda tool used by the Shia and the Sunnis opposed to them. Strong pro-Mu'awiya sentiments were voiced by Sunnis in several Abbasid cities, including [[Baghdad]], [[Wasit]], [[Raqqa]] and [[Isfahan]]. At about the same time, the Shia were permitted by the Buyids and the Sunni Abbasid caliphs to perform the ritual cursing of Mu'awiya in mosques.{{sfn|Kraemer|1992|pp=64–65}} In 10th–11th-century Egypt, the figure of Mu'awiya occasionally played a similar role, with the [[Isma'ili Shia]] [[Fatimid Caliphate|Fatimid]] caliphs introducing measures opposed to Mu'awiya's memory and opponents of the government using him as a tool to berate the Shia.{{sfn|Halm|2003|pp=90, 192}}
