It was originally known as the Kingdom of Jin (震, Zhen) until 713 when its name was changed to Parhae. At its greatest extent it corresponded to what is today [[Northeast China]], the northern half of the [[Korean Peninsula]] and the southeastern [[Russian Far East]].<ref>{{cite journal|author=정석배 JUNG Suk-bae|year=2016|script-title=ko:발해의 북방경계에 대한 일고찰 (Study on northern borders of Balhae) |journal=고구려발해연구 The Koguryo Parhae Yongu |publisher=고구려발해학회 Association of Koguryo Parhae|pages=88|volume=54|language=ko}}</ref>

Parhae's early history involved a rocky relationship with the [[Tang dynasty]] that saw military and political conflict, but by the end of the 8th century the relationship had become cordial and friendly. The Tang dynasty would eventually recognize Parhae as the "Prosperous Country of the East".<ref name="OwenMiller" /><ref name="y-history.net">{{cite web |script-title=ja:渤海／海東の盛国 |url=https://www.y-history.net/appendix/wh0302-088.html |access-date=19 February 2019 |website=www.y-history.net |language=ja}}</ref><ref name=":0">{{Cite book|last=Lee|first=Ki-baik|url=https://www.google.ca/books/edition/A_New_History_of_Korea/z2n9DwAAQBAJhl=en&gbpv=1&dq=parhae%20clothing&pg=PT77&printsec=frontcover&bsq=parhae%20clothing|title=A New History of Korea|date=1988|others=Edward W.

Parhae was conquered by the [[Khitan people|Khitan]]-led [[Liao dynasty]] in 926. Parhae survived as a distinct population group for another three centuries in the Liao and [[Jin dynasty (1115–1234)|Jin]] dynasties before disappearing under [[Mongol Empire|Mongol rule]].

The history surrounding the origin of the state, its ethnic composition, the modern cultural affiliation of the ruling dynasty, the reading of their names, and its borders are the subject of a [[Balhae controversies|historiographical dispute]] between Korea, China and Russia. Historical sources from both China and Korea have described Parhae's founder, Tae Choyŏng, as related to the [[Mohe people]] and [[Goguryeo]].

In 713, the [[Tang dynasty]] bestowed the ruler of Jin with the noble title "Prince of [[Commandery (China)|Commandery]] of [[Bohai Commandery|Bohai]] (Parhae)" (渤海郡王).{{r |OldTangBook2019 |page=§5.1 ¶3 |quote=睿宗先天二年，遣郎將崔訢往冊拜祚榮爲左驍衛員外大將軍、渤海郡王}} In 762, the Tang formally elevated Parhae to the status of a kingdom.<ref name="Dillon2016"/><ref name="Kim2012"/>{{r |OldTangBook2019 |page= §5.1 ¶11 |quote=寶應元年，進封國王}} The kingdom's territories did not overlap with the Bohai Commandery. According to Jin Yufu, the Tang referred to the state as [[Mohe people|Mohe]] (Kr. Malgal, name of the ethnic group) until 713, and "Parhae" was possibly used as a different transcription of the same name.<ref>金毓黻. 东北通史（再版）. 社会科学战线杂志社 (1981). pp. 253–264.</ref> According to the ''[[New Book of Tang]]'', the state was called Mohe before it received investiture from China and assumed the name Bohai.{{sfn|Kim|2015|p=8}} Linguists [[Karl Heinrich Menges]] and [[Roy Andrew Miller]] raised another theory, suggesting that the name Parhae had an underlying native name which was cognate to [[Manchu language|Manchu]] ''butha'' ("hunting").<ref>{{cite journal |last1=Janhunen |first1=Juha |title=Liao: A Manchurian hydronym and its ethnohistorical context |journal=Studia Etymologica Cracoviensia |date=2008 |volume=13 |page=94 |url=http://cejsh.icm.edu.pl/cejsh/element/bwmeta1.element.ojs-nameId-49b94d03-b5da-3b30-b733-c85e11ddfcc0-year-2008-volume-13-issue-1-article-1073/c/1073-1069.pdf}}</ref>

The transcriptions '''Bohai'''{{sfn|Crossley|1997|p=18}} (Chinese [[pinyin]] romanization), '''Po-hai'''{{sfn|Crossley|2016|p=12}} (Chinese [[Wade–Giles]] romanization), and '''Balhae''' ([[Revised Romanization of Korean]]) are also used in modern academia. Most Western-language scholarship have opted for Bohai except in the field of Korean studies; however, some scholars have chosen the Korean romanization to avoid a "Chinese" narrative spread by the usage of ''pinyin'' romanization.{{sfn|Sloane|2014|p=366}} According to [[Pamela Kyle Crossley]], neither Chinese or Korean transliterations can be correct. She chose to use modern Chinese transliteration "to indicate that the only referent we have is Chinese characters".{{sfn|Crossley|2016|p=12}} Jesse D. Sloane chose to use "Parhae" because it was not covered in depth in the state-mandated curriculum of China, but used Chinese romanization for all other terms related to Parhae that appeared in Chinese sources first. Neither Crossley or Sloane meant to depict Parhae as essentially Chinese but used Chinese romanization out of convenience and to acknowledge the transnational origins of Parhae discourse.{{sfn|Sloane|2014a|p=4}}{{sfn|Crossley|2016|p=12}}

===Origin===

{{Kings of Balhae}}
In 696, [[Li Jinzhong]] (Wushang Khan) of the [[Khitan people|Khitans]] along with his brother-in-law [[Sun Wanrong]] rebelled against Tang (Wu Zetian's [[Zhou dynasty (690–705)|Zhou Dynasty]]<ref>{{cite book |last1=Uwitchett |first1=Denis |title=Chen gui and Other Works Attributed to Empress Wu Zetian. |page=20 |url=https://www2.ihp.sinica.edu.tw/file/1471iwFGrCg.pdf |access-date=29 August 2020 |archive-date=25 October 2020 |archive-url=https://web.archive.org/web/20201025104451/https://www2.ihp.sinica.edu.tw/file/1471iwFGrCg.pdf |url-status=live }}</ref>) hegemony, killed an abusive Tang commander, and attacked [[Hebei]]. Li died soon after and Sun succeeded him, only to be defeated by the [[Second Turkic Khaganate]].{{sfn|Wang|2013|p=85}} The population of Yingzhou (營州, modern-day [[Chaoyang, Liaoning|Chaoyang]], [[Liaoning]]) fled eastward toward the [[Liao River]] during the turmoil. The Tang tried to appease [[Tae Chungsang]] (Da Zhongxiang) and [[Kŏlsa Piu]] (Qisi Biyu), two local leaders, by granting them the titles of Duke of Zhen (Jin) and Duke of Xu (Heo) respectively. Geolsa Biu rejected the offer but was soon defeated by a Tang force led by [[Li Kaigu]], while Tae Chungsang fled with his followers but also died around the same time. Tae Chungsang's son, [[Tae Choyŏng]] (Da Zuorong), left the Liao River valley for Mt. Tianmen (in modern [[Jilin Province]]). There, he dealt a heavy defeat to the Tang forces at the [[Battle of Tianmenling]] (Cheonmunnyeong), after which he led his followers to set up a state. In 698, Tae Choyŏng declared himself King of Zhen (Jin).{{sfn|Wang|2013|p=87}}<ref>{{Citation

Another account of the events suggests that there was no rebellion at all, and the leader of the [[Sumo Mohe]] (Songmal Malgal) rendered assistance to the Tang by suppressing Khitan rebels. As a reward the Tang acknowledged the leader as the local hegemon of a semi-independent state.{{sfn|Crossley|1997|p=18}}

In diplomatic communications between [[Silla]] and Jin, Silla attempted to confer investiture to Tae Choyŏng with the title of a fifth rank official: "Dae achan".{{sfn|Kim|2011a|p=348}} Silla conferred this mid-ranking investiture partially out of a sense of superiority, but also because Parhae was a relatively new kingdom whereas Silla had been centuries old. The people of Jin did not know the system of ranks used in Silla and thus accepted the title. After a while, Tae Choyŏng realized the meaning of the title and sought to change Parhae's international status. In 713 or 714, the Tang dynasty recognized Tae Choyŏng as the "Prince of Bohai (Parhae)", the name for the sea surrounding [[Liaodong]] and [[Shandong]].<ref name="Kim2012"/>

According to Alexander Kim, neither the Tang or Silla recognized Parhae as the successor of Goguryeo. The Tang considered it a dukedom while Silla considered it their vassal.<ref name = "Kim2014"/> South Korean historians such as Kim Eng Gug, however, believe that the Tang viewed Parhae as Goguryeo's successor.<ref>{{cite book |last1=Kim |first1=Eun Gug |chapter=An Enduring Window between North and South: Parhae and Silla |title=A New History of Parhae |date=2012 |publisher=Brill |page=76}}</ref> Between 713 and 721, Silla constructed a northern wall to maintain active defences along the border.{{sfn|Kim|2011a|p=349}} The Tang later recognized Parhae as a kingdom in 762 but Silla continued to view Parhae as a rebellious vassal. However, Kim Eun Gug argues that the "bestowal of a fifth-rank position was an expression of Silla's confidence, and such an exchange would have been unimaginable if Silla and Parhae were in a hostile relationship."<ref>{{cite book |last1=Kim |first1=Eun Gug |chapter=An Enduring Window between North and South: Parhae and Silla |title=A New History of Parhae |date=2012 |publisher=Brill |pages=77–78}}</ref> After Tang recognition of Parhae as a kingdom, Parhae diplomatic missions to Japan began to refer to the Parhae ruler as descended from Heaven. Japanese officials criticized these letters, revised them, and limited diplomatic missions from Parhae. A royal epitaph and Buddhist scripture confirm this designation for the ruler of Parhae.<ref name = "Kim2014"/>

===Ethnic identity===
The ethnic identity of Parhae's founder is [[Balhae controversies|controversial]] and disputed. Many Chinese, Korean, Russian, and Japanese scholars of Parhae believe its population was composed of Goguryeo remnants and Mohe tribes.{{sfn|Kim|2011|p=292}} Chinese scholars consider that Mohe people form the ethnic majority of Parhae, and arguments for this opinion are also viewed positively in Russia{{sfn|Kim|2011|p=292}} and in the West.<ref name="vovin_script"/> While modern Korean scholars usually consider Parhae a Korean state and one of the [[Northern and Southern States period|Northern and Southern States]] of Korea, Russian and Chinese scholars reject this notion, echoing the position of historical Korean scholars such as [[Kim Pusik]], author of the ''[[Samguk sagi]]''.{{sfn|Kim|2011|p=292}}

Some historians view this dispute as the polemics reflecting modern politics rather than historical evidence.{{sfn|Kim|2011|p=299}}

{{blockquote|The problem about Parhae history is that many questions are beyond a simple answer. Different, nearly contemporary, sources represent fundamental questions in very different ways with different possible interpretations.{{sfn|Reckel|2015|p=481-482}}|Johannes Reckel}}

{{blockquote|The question of the ethnic composition of the Bohai state has become a political problem in the East Asian region. Chinese and Korean historians alternatively regard Bohai as a Chinese provincial power or as an independent Korean country, based on intrinsically subjective positions. Certainly, all Korean specialists believe that the Koguryŏ population was dominant in Bohai. But Chinese historians tend to disagree, believing that Bohai was a Chinese province with some political autonomy, with the Mohe people as its main population.{{sfn|Kim|2015|p=7-8}}|Alexander Kim and Min Kyounghyoun}}

According to [[Ch'oe Ch'iwŏn]] (b. 857), the people of Parhae were Mohe.{{sfn|Kim|2011|p=293}} In the conflict between the joint Tang-Silla forces against Parhae, Silla described Parhae as "rebellious barbarians."{{sfn|Kim|2011a|p=351}} Sillan aristocracy tended to view the Parhae population as consisting of solely Mohe people, but this could be due to the antagonistic relations between the two states causing the Sillan nobility to ignore Goguryeo elements of Parhae ethnic composition.{{sfn|Kim|2015|p=8}} The ''[[Ruijū Kokushi]]'', a 9th-century Japanese text, says that when Parhae was founded, it spanned 2,000 ''li'' and was filled with villages, each of which were Mohe tribes.<ref><類聚国史>卷一九三记载:天皇二年(698年),大祚荣始建渤海国,其国延袤二千里,无州县馆驿,处处有村里,皆靺鞨部落。其百姓者 靺鞨多,土人少,皆以土人为村长.</ref>{{sfn|Kim|2011|p=292}} Japanese diplomatic communications with Parhae recognized it as a "state of Go[gu]ryeo."<ref name="Kim2012"/> In the early 12th century, the [[Jurchens|Jurchen]] leader [[Emperor Taizu of Jin|Aguda]] sent ambassadors to the Liao dynasty to call on the Parhae people there to rebel against the Liao by appealing to a common origin between the Jurchens and Parhae. According to the appeal, both the Jurchens and Parhae people descended from the seven Wuji tribes. However, according to Alexander Kim, this only applied to the Mohe portion of Parhae's population and not the Goguryeo people, who were not included in the seven Wuji tribes.{{sfn|Kim|2011b|p=173}} The ''[[Samguk sagi]]'', written in the 12th century by [[Kim Pusik]], did not consider Parhae a Korean state.{{sfn|Kim|2011|p=292}} The ''[[Samguk yusa]]'', a 13th-century collection of Korean history and legends, describes Tae as a Sumo Mohe leader. However, it gives another account of Tae being a former Goguryeo general, citing a now-lost Sillan record.<ref>''Samguk yusa'', Chapter 1, Section Mohe Bohai. 通典云，渤海，本栗未靺鞨。至其酋柞榮立國，自號震旦。 [...] 又新羅古記云，高麗舊將柞榮，姓大氏。</ref> Kim considers this unlikely since Goguryeo fell in 668 while Tae died in 719, and young men could not receive the rank of general.{{sfn|Kim|2011|p=297}}

{{blockquote|As we know in relation to the origin of the Bohai people, when Gouli (Koguryŏ) was not yet destroyed, they [the Bohai people] were the useless tribe of Mohe.

Russian scholars argue that the ethnic composition of Parhae cannot be determined with great precision because no materials exist that can confirm either the Chinese or Korean claims. Some Russian scholars claim Parhae as part of Manchurian history while others believe Parhae was neither a Korean state or Chinese province and there is no direct link between Parhae and either modern China or Korea.{{sfn|Kim|2011|p=299}} E. V. Shakunov believes that Parhae's population also consisted of elements from [[Central Asia]] such as [[Sogdians]] and [[Tocharians]].

===War with the Tang dynasty===
[[Tae Choyŏng]] died in 719 and was succeeded by his son, [[Tae Muye]] (Da Wuyi, r. 719–737). While Muye accepted Tang gifts and title upon his succession, he showed his independence by giving his father a posthumous [[temple name]], Gowang/Gaowang (high king). Muye adopted his own reign title in 720.{{sfn|Wang|2013|p=88}} In 721, the Tang asked Parhae for military support against the [[Khitan people|Khitans]] but they refused.{{sfn|Kim|2011a|p=350}} To check Parhae's influence, the Tang appointed a chieftain of the [[Heishui Mohe]] (Heuksu Malgal) as prefect of Bozhou (in modern [[Khabarovsk]]) in 722. In 725, the [[Andong Protectorate]] suggested stationing an army in the region. In response, Tang officials dispatched an administration staffed by the leaders of smaller tribes under the command of the [[Youzhou]] governor-general. Muye was convinced that the Heishui Mohe and the Tang were plotting to attack him and required a preemptive strike. He ordered his brother, {{ill|Tae Munye|ko|대문예|zh|大门艺}} (Da Wenyi), to attack the Heishui Mohe. Munye, who had stayed at the Tang capital as a hostage since the start of peaceful relations in 705, and understood the implications of attacking a Tang ally, was reluctant to carry out the order. He advised Muye to abandon the plan twice.{{sfn|Wang|2013|p=89}}{{sfn|Kim|2011a|p=349}}

{{blockquote|When Goguryeo was at its peak, the country had 300,000 elite soldiers. It resisted the Tang court and refused to submit itself to China. As soon as the Tang troops reached the country, however, Goguryeo was swept into the dust. Now the population of Balhae is several times less than that of Goguryeo. Yet you want to betray the Tang court. We must not do it.{{sfn|Wang|2013|p=89}}|{{ill|Tae Munye|ko|대문예|zh|大门艺}}}}

Muye paid his brother no heed and used his reluctance as pretext to remove Munye from command. Munye fled to the Tang dynasty. A Parhae envoy arrived at the Tang court in 732 requesting the execution of Munye. In response, the Tang secretly sent Munye to [[Central Asia]] while informing Muye that his brother had been banished to [[South China]]. The reality of events, however, leaked out, enraging Muye. A Parhae naval force led by [[Chang Munhyu]] (Zhang Wenxiu) attacked Dengzhou on the north shore of the [[Shandong Peninsula]] and killed its prefect.{{sfn|Wang|2013|p=89-90}}<ref>{{cite web |script-title=ru:История государства Бохай |url=http://www.rezerv.narod.ru/history/ussur-bohaihist.htm |access-date=25 February 2019 |website=www.rezerv.narod.ru |language=ru}}</ref> Additionally, Dengzhou was the center of maritime trade routes in East Asia, and was the locale where both Silla and Parhae envoys stayed when coming to pay tribute to the Tang Emperor. As a result, Parhae's attack on Dengzhou was not merely motivated by geopolitical retaliation against the Tang but also out a of a desire to assert its newfound maritime prowess as well as prevent the Heishui Mohe from establishing trade relations with the Tang, which would have weakened Parhae's dominace of the northern trade routes. Parhae's successful attack on Dengzhou also demonstrates a surprising maritime prowess for a thirty-year old state, which had military naval vessels that could cross the sea as well as merchant vessels that could carry out trade activities.<ref>{{cite book |last1=Kim |first1=Eun Gug |chapter=An Enduring Window between North and South: Parhae and Silla |title=A New History of Parhae |date=2012 |publisher=Brill |pages=80–81}}</ref>

In response to the attacks, the Tang ordered Kim Chungsin, the nephew of [[Seongdeok of Silla]] and courtier in the Tang court, to return to [[Silla]] and organize an attack on Parhae. Chungsin excused himself from the request by asking to remain in China as the emperor's bodyguard. In his place, the Tang sent Kim Saran, a low ranking Sillan diplomat, and a Tang eunuch. Munye was also recalled to recruit soldiers in Youzhou. In the meantime, Parhae struck again, sacking the town of Mt. Matou (northwest of modern [[Shanhaiguan]]), and killing 10,000 Tang soldiers. The Parhae force raided and pillaged along the Liao River and the coast of the [[Liaodong Peninsula]]. In 733, Tang and Sillan forces attempted a joint attack on Parhae but were accosted by a blizzard that blocked all roads and killed half of the 100,000 Tang-Silla army, forcing them to abort the invasion.{{sfn|Wang|2013|p=90-91}} Muye continued to try to kill his brother. He sent an agent to [[Luoyang]] to plot the assassination of his brother. Munye was attacked in broad daylight near the Tianjin Bridge outside the imperial palace but escaped unharmed.{{sfn|Wang|2013|p=91}}

===Reconciliation with the Tang===
In 734, Silla attacked Parhae with no success. In an effort to curb Parhae's ambitions, the Tang granted Silla's request to place troops in the [[Daedong River|Paegang]] [[Hwanghae Province|region]] in 735.{{sfn|Wang|2013|p=91}}

The strategic landscape began to turn on Parhae in 734–735, when the [[Khitan people|Khitan]] chieftain, Ketuyu, and his Turkic allies were defeated by Tang forces. In addition a force of 5,000 [[Kumo Xi]] cavalrymen surrendered to the Tang. The defeat of the Khitans and [[Turkic peoples|Turks]], and the submission of the Kumo Xi removed the buffer zone that had formed between Parhae and the Tang. Sensing the change in strategic developments, Muye decided to reconcile with the Tang. In 737, Tang sailors and civilians detained in Parhae were repatriated. In 738, an envoy from Parhae requested Tang ritual codes and dynastic histories in a symbolic gesture towards peace. Muye died soon after.{{sfn|Wang|2013|p=92}}

===Relations with Japan===
Japanese records indicate that Parhae and Japan enjoyed very amicable relations. When King Mu sent Parhae's first envoy delegation to Japan in 727, the mission was made up of 24 men, which included high-ranking generals such as 
Ko Inŭi and Ko Chedŏk. King Mu had 300 sable furs sent by the Parhae delegation to Japan as both a show of goodwill and a desire to foster friendly relations with Japan.<ref>{{cite book |last1=Kim |first1=Eun Gug |chapter=An Enduring Window between North and South: Parhae and Silla |title=A New History of Parhae |date=2012 |publisher=Brill |page=78}}</ref>

Muye's son and successor, [[Tae Hŭmmu]] (Da Qinmao, r. 737–793), continued the course of reconciliation with the Tang. At the same time, trouble with the [[Tibetan Empire]] to the west forced the Tang to withdraw all military forces from [[Korea]] and adopt a defensive stance. Hŭmmu cemented the geopolitical balance by sending an envoy to the Japanese court, which his father had done as well in 728 to threaten Silla with an ally from the southeast. Parhae kept diplomatic and commercial contacts with Japan until the end of the kingdom. Parhae dispatched envoys to Japan 34 times, while Japan sent envoys to Parhae 13 times.<ref>[http://english.historyfoundation.or.kr/his/acij.asp?pgcode=040201 9 Balhae and Japan] {{webarchive|url=https://web.archive.org/web/20150626104047/http://english.historyfoundation.or.kr/his/acij.asp?pgcode=040201 |date=26 June 2015 }} Northeast Asian History Foundation</ref>

Parhae planned a joint attack on Silla with Japan. [[Gyeongdeok of Silla]] offended Japan twice. In 753  he treated Japanese ambassadors with arrogance and in 758 he refused to meet them. After 758, Japan asked Parhae to attack Silla with them. Parhae and Japan exchanged ambassadors several times in the 750s and 760s to plan for the attack. Silla likely knew of these plans and prepared by building six castles along the border with Parhae in 762. The border region changed hands many times but the losses are not described in Silla's official history, only the dates when an army was sent north. Japan prepared a fleet to invade southern Silla; however the plan never came to fruition.{{sfn|Kim|2011a|p=352}}

In 755, the [[An Lushan Rebellion]] broke out, causing the Tang to lose control of the northeast, and even after the rebellion's end in 763, warlords known as [[jiedushi]] controlled the former northeastern part of the Tang empire. In 762, [[Emperor Daizong of Tang]] formally recognized Parhae as a state and Hŭmmu as its king.{{sfn|Wang|2013|p=93}} Although China recognized him as a king, Parhae itself referred to him as the son of heaven (emperor) and a king. The consort of the ruler was also called empress.{{sfn|Sloane|2014a|p=15}}<ref>{{cite web|author=ŔĚżĎąŮ |url=http://www.seelotus.com/gojeon/gojeon/hanmun/ya-cheong-do.htm |script-title=ko:야청도의성(夜聽擣衣聲) |publisher=Seelotus.com |access-date=12 September 2012|language=ko}}</ref> A record in 834 says that Parhae had both kings and great kings. The epitath of Princess Chŏnghyo (Zhenxiao), daughter of Hŭmmu, states that her father was a "great king."<ref name = "Kim2014"/>

===Internal development===
During Hŭmmu's reign, a trade route with Silla, called "Sillado" ({{Korean|hangul=신라도|hanja=新羅道|labels=no}}), was established. The Silla trade route began at the Eastern Capital located at the center of  Parhae's Yongwon Province, came down along the coast past what is now Hamgyong Province. This route, which also passed through Parhae's Southern Capital, was established for the purpose of conducting trade with Silla. Since the 1980s large numbers of archaeological sites related to Parhae have been excavated in North Korea; among those sites, the fortress at Bukcheong and the monastery site at Omae-ri in the city of Sinpo were locales engaged in the trade between Parhae and Silla. The route led from Pukchong, which was Parhae's Southern Capital, down along the coast to the Yonghung River; across the river was Silla's Chonjong (Jeonjeong) Prefecture.<ref>{{cite book |last1=Kim |first1=Eun Gug |chapter=An Enduring Window between North and South: Parhae and Silla |title=A New History of Parhae |date=2012 |publisher=Brill |page=79}}</ref> Hŭmmu moved the capital of Parhae several times. He also established [[Shangjing Longquanfu|Shangjing]]/Sanggyeong, the permanent capital near [[Lake Jingpo]] in the south of today's [[Heilongjiang]] province around 756,{{sfn|Shin|2014|p=66}} stabilizing and strengthening central rule over various ethnic tribes in his realm, which was expanded temporarily. He also authorized the creation of the ''Jujagam''/''Zhouzijian'' ({{Korean|hangul=주자감|hanja=胄子監|labels=no}}), the national academy, based on the [[Guozijian|national academy of Tang]].

===Conflict with Mohe tribes and Silla===
The bilateral relationship between the Tang and Parhae grew friendlier. From 766 to 779, 25 missions from Parhae paid respect to Daizong. By the end of Hŭmmu's reign in 793, princes from Parhae's royal family were serving as guards at the court of [[Emperor Dezong of Tang]] of their own volition. Peace with the Tang allowed Parhae to further expand its territory. After the death of Hŭmmu, who was [[posthumous name|posthumously known]] as [[Mun of Balhae|Mun]] (Wen, r. 737–793), Parhae experienced a succession crisis. As a result, Parhae lost territory and bordering Mohe tribes rebelled. Both the reigns of [[Sŏn of Balhae|Sŏn]] (Xuan, r. 818–830) and [[Tae Ijin]] (Da Yizhen, r. 830–857) saw intrusions by Mohe tribes.{{sfn|Kim|2011|p=286}} Sŏn annexed the Yuexi Mohe and other tribes along the Amur valley in the north.{{sfn|Wang|2013|p=94}} In 818-820, he also invaded Liaodong and parts of Silla on Parhae's southern border.{{sfn|Shin|2014|p=66}} In 826, Silla mobilized tens of thousands of people to fortify the border with Parhae.{{sfn|Kim|2011a|p=354}} In the middle of the 9th century, Parhae completed its local administrative system, which was composed of five capitals, 15 prefectures and 62 counties.{{sfn|Kim|2011|p=286}}

===Fall===
In 907, Parhae came into conflict with the Khitan [[Liao dynasty]] because of the decision of the [[Khitan people|Khitans]] near modern [[Chifeng]] and [[Tongliao]],<ref>[https://cyberleninka.ru/article/n/o-dzasak-hanah-perednego-znameni-levogo-kryla-horchinov-pri-dinastii-tsin/viewer About Zusak-khan front banner of the left wing of korchenov of the Qing dynasty]</ref> who recognized the supremacy of Parhae, to become part of the Liao dynasty. The Liao ruler [[Abaoji]] took possession of the [[Liao River]] basin, which led to a long conflict.<ref name="Crossley 2016"/> In 911, Silla allied with Parhae against the Khitans.{{sfn|Kim|2011a|p=354}} In 924, Parhae attacked the Khitans. The next year, a Parhae general, Sindeok, surrendered to [[Goryeo]]. In 925, Silla allied with the Khitans and helped them in their war against Parhae. Afterwards, warriors from Silla were rewarded by the Khitan ruler.{{sfn|Kim|2011a|p=353}} In 926, the Khitans laid siege to the Parhae capital [[Shangjing Longquanfu|Shangjing]]/Sanggyeong and forced their surrender.{{sfn|Shin|2014|p=66}} 

In Parhae's place, the Khitans established the autonomous kingdom of [[Dongdan Kingdom|Dongdan]] (''Dan gur'' in Khitan), which means Eastern ''Dan'' Kingdom, ruled by the Liao crown prince [[Yelü Bei]].{{sfn|Twitchett|1994|p=69}} For a time the Parhae royal family continued to administer their former territory as Liao appointees in conjunction with Yelü aristocrats from Abaoji's Diela federation.{{sfn|Crossley|2016|p=16-17}} Its independence ended in 929 when a new Liao ruler ordered the relocation of its population.{{sfn|Twitchett|1994|p=69}} It was soon absorbed into the Liao in 936.<ref name="Dillon2016" /> The name of Parhae was officially removed in 982.{{sfn|Dillon|2016|p=55-56}} Meanwhile, a series of nobilities and elites led by key figures such as crown prince [[Tae Kwanghyŏn]], were absorbed into [[Goryeo]].<ref>{{Cite journal|title=North and South States Period: Unified Silla and Balhae|url=http://www.korea.net/AboutKorea/History/Unified-Silla-Balhae|journal=Korea}}</ref> Some Parhae aristocrats were forced to move to Liaoyang, but the eastern territory was recaptured by the Parhae nobles as [[Later Parhae]], which was later renamed to [[Chŏngan]] (Ding'an).

Some scholars considered [[946 eruption of Paektu Mountain|the eruption of Mount Paektu]] in the 930–940s to have dealt a final blow to the surviving forces of Parhae based on records of massive population displacement of Parhae people to the Liaodong peninsula of the Khitan empire and the Korean peninsula of Goryeo.<ref>{{cite web |script-title=ko:발해멸망과 백두산 화산폭발 |trans-title=The Fall of Bohai and the Mt. |url=http://m.khan.co.kr/view.html?art_id=201205300951451 |website=Khan.co|date=30 May 2012 |language=ko}}</ref><ref>{{cite news |title=Eruption of Mt.

[[Pamela Kyle Crossley|Crossley]] believes that according to Goryeo records, Parhae refugees only arrived in groups of a few hundred to a few thousand. She suggests that the total number could not be more than 100,000, while millions remained in Liao-controlled territories. According to Crossley, it is also unclear whether they stayed, went back to Parhae, or moved on elsewhere like China or Japan.<ref name="Crossley 2016"/> According to Kim, between the 10th and 11th centuries, 30,000 Parhae families (more than 100,000 people) immigrated to Goryeo, 94,000 local families (470,000 inhabitants) were deported by the Liao, and only 20,000 Parhae families lived in the former territories of Parhae, a significantly smaller figure than those that immigrated to Goryeo.{{sfn|Kim|2019|p=108, 110}} Korean historians generally estimate that approximately 100,000 to 200,000 fled from Parhae to Goryeo.<ref>{{cite book |last1=김 |first1=위현 |title=渤海遺民의 再建運動 : 後渤海와 大渤海}}</ref><ref>{{cite book |last1=나 |first1=영남 |title=《요·금시대 이민족 지배와 발해인》. 외대 역사문화 연구총서 |date=2017 |publisher=History and Culture Research Series at the University of Foreign Studies}}</ref> Historian Professor Park Jong-gi estimated that 120,600 people fled from Parhae to Goryeo, and by themselves comprised approximately 6.3% of early Goryeo's roughly 2 million inhabitants.<ref>{{cite web |last1=Lee |first1=Sang-Do |script-title=ko:[평화칼럼] 발해 유민(遺民)과 꼬마 난민(難民) '쿠르디' |url=http://m.cpbc.co.kr/paper/view.php?cid=598022&path=201510 |website=Catholic Peace Newspaper |access-date=8 February 2023}}</ref>

According to Kim, many Parhae refugees fled to Goryeo due to pro-Parhae policies during the mid 9th century. In the first few decades after Parhae's fall, Parhae refugees were welcomed by Goryeo. However, it seems few Parhae refugees retained high positions in Goryeo as service in the Khitan administration offered more benefits. Goryeo annals contain only six names of high-ranking officials who were of Parhae origin. From 1029 to 1030, the Khitan Administration was rocked by a rebellion by Parhae people after the government tried raising taxes on them. The leader of the rebellion was the Liao general [[Da Yanlin]], a 7th generation descendant of the founder of Parhae. He arrested and killed Khitan leaders and proclaimed the establishment of a new dynasty, [[Xingliao|Xing Liao]]. He sent an ambassador to Goryeo requesting military support. Goryeo sent some military troops against the Liao but the Khitans repelled them and expelled the Goryeo army. Some of Goryeo's officers sought further confrontation with the Liao, but the Goryeo diplomatic corps and nobility asked the Goryeo king to exercise caution. The Goryeo king decided to abandon military activities against the Liao. Despite this, Parhae people continued to send missions to Goryeo requesting assistance. The last mission, led by Lee Kwang Rok, arrived after the destruction of the state, and Kim considers this group as refugees, not members of an ambassadorial mission. Kim believes that in the 11th century, Parhae people under the Liao started viewing Goryeo as a hostile state in which the Parhae people lacked support.{{sfn|Kim|2019|p=109-1010}}

====Liao dynasty====
The Parhae people played a pivotal role in the politics, literature, and society of northern China under the Liao and Jin dynasties. After the dissolution of Parhae by the Khitan empire, the term "Bohai" was used through the fourteenth century to denote a subset of the populations of the Liao, Jin, and [[Mongol Empire|Mongol empire]]s.<ref>{{cite journal |last1=Jesse D |first1=Sloane |title=Mapping a Stateless Nation: "Bohai" Identity in the Twelfth to Fourteenth Centuries |url=https://muse.jhu.edu/article/611400 |journal=Journal of Song-Yuan Studies|year=2014 |volume=44 |pages=365–403 |doi=10.1353/sys.2014.0003 |s2cid=164130734 |url-access=subscription }}</ref> The Liao Eastern Capital (Dongjing, modern-day [[Liaoyang]], [[Liaoning]]) served as a base for monitoring the former Parhae territories. The city's residents, over 40,000 in early tenth century, were primarily Parhae, according to a figure cited by Pamela Crossley. [[Tae Insŏn]] (Da Yinzhuan), the last Parhae king, and other members of the former royal lineage still held considerable authority in [[Dongdan Kingdom|Dongdan]] and the Eastern Capital after Parhae's fall. Some Parhae elites, on the other hand, were integrated into the Liao aristocracy and often changed their personal identities dramatically.<ref name="Crossley 2016">{{cite journal |last1=Crossley |first1=Pamela Kyle |title=Bohai/Parhae Identity and the Coherence of Dan gur under the Kitan/Liao Empire |journal=International Journal of Korean History |date=2016 |volume=21 |issue=1 |pages=11–44 |doi=10.22372/ijkh.2016.21.1.11|doi-access=free }}</ref>

According to Wittfogel and Feng, an undated Liao census puts the number of Parhae households in Liaoyang at around 100,000, which would be around half a million individuals.<ref>{{cite book |last1=Wittfogel |first1=Karl August |last2=Feng |first2=Chia-Sheng |title=History of Chinese Society: Liao |page=56 }}</ref>{{sfn|Sloane|2014|p=390}}

After the semi-autonomous kingdom of [[Dongdan Kingdom|Dongdan]] that had been set up in former Parhae territory was abolished in 929 and its ruler, [[Yelü Bei]], fled in 930, Parhae's territory started to be integrated into the Liao dynasty. A large part of Parhae's administrative structure was dismantled and the Liao sent Han and Khitan settlers, most of whom were soldiers, to colonize former Parhae territory. However, the region was treated as a tributary state for tax purposes. An annual payment of 1,000 horses and 150,000 bolts of cloth was levied on the region, but monopoly taxes on salt and wine did not exist, and there were only minimal taxes on commerce. In the 1020s, the Southern Establishment which administered the settled areas of the Liao dynasty tried to extend its taxation system to the Parhae people of the defunct Dongdan kingdom who previously only had to pay the reduced tribute payment. The Parhae people were ordered to build boats to transport grain to the [[Nanjing (Liao dynasty)|Southern Capital]]. The journey was dangerous and many boats were lost, leading to resentment.{{sfn|Twitchett|1994|p=113-114}}

In the summer of 1029, a distant descendant of Parhae royalty, [[Da Yanlin]], rebelled at the Eastern Capital. He imprisoned minister Xiao Xiaoxian and his wife, killed the tax commissioners and chief military commander, and declared his own Xing Liao dynasty (興遼國/흥료국). He requested aid from Goryeo, who sent forces against Liao only to be repelled. Further ambassadors were sent by Xing Liao to Goryeo seeking aid but Goryeo refused to help them owing to the advice of nobles and scholars to the Goryeo king. Four groups of ambassadors were sent but the last group remained in Goryeo rather than return. Other Parhae people serving in the Liao military also refused to join Xing Liao. Instead only a handful of [[Jurchens]] joined his regime. Many participants of the rebellion probably realized the weakness of the new dynasty and fled to Goryeo before its collapse.{{sfn|Kim|2019|p=110}} A year later, one of Da Yanlin's officers betrayed him and opened the Eastern Capital's gates to the Khitans. His short lived dynasty came to an end. The old Parhae nobility were resettled near the Supreme Capital while others fled to Goryeo.{{sfn|Twitchett|1994|p=113-114}} 

In 1114, Parhae descendants took advantage of the Jurchen-Khitan war and rebelled under the leadership of Gu Yu, who commanded 30,000 soldiers. They defeated Khitan armies twice before they were destroyed.{{sfn|Kim|2011|p=287}} In 1116 another rebellion occurred at the Eastern Capital when a Parhae officer named Gao Yongchang declared himself emperor of the Yuan dynasty and requested aid from the Jin. Liao troops sent to quash the rebellion were themselves led by those of Parhae descent.{{sfn|Sloane|2014|p=370}} The Jin relief troops to Yuan easily repulsed the Liao troops but then turned on the Parhae rebels and killed Gao Yongchang.{{sfn|Twitchett|1994|p=143-144}}

The distinction between Parhae and Jurchen rebellions was not always clear to the Liao. In the 1117 epitaph of an officer who died while fighting against Jurchens in 1114, the Parhae and Jurchens were mentioned in connection to each other and placed within a similar category.{{sfn|Sloane|2014|p=372}}

====Jin dynasty====
The Khitans themselves eventually succumbed to the [[Jurchen people]], the descendants of the Mohe, who founded the [[Jin dynasty (1115–1234)|Jin dynasty]]. Jurchen proclamations emphasized the common descent of the Parhae and Jurchens from the seven Wuji (勿吉) tribes. The Jin sent two Parhae representatives to recruit "people from their home area" while bearing a message that "The Jurchen and Bohai are originally of the same family; as we rise in arms to smite the wicked, [harm] will not unjustly reach the innocent."{{sfn|Sloane|2014|p=373}} The fourth, fifth and seventh emperors of Jin were mothered by Parhae consorts.{{sfn|Sloane|2014|p=381}} Nevertheless, the 13th century census of Northern China by the Mongols distinguished Parhae people who belonged to the Khitan Empire from other ethnic groups such as Goryeo, Khitans and Jurchens.<ref name="Hong Won-tak page 80-110">Hong Won-tak. "''Liao and Jin: After Khitan and Xianbei in West Manchuria, Jurchen in Eastern Manchuria appeared''" East Asian History: Distortion and Correcting, page 80-110. Seoul: Gudara, 2012.</ref>

A Song observer notes that during the Liao era, Parhae people were not employed in the government, as a result they were the first to defect to the Jin.{{sfn|Sloane|2014|p=376}} The call for Parhae defectors was met with significant success. Aguda was advised by a Parhae man named Yang Pu who aided him in establishing an imperial court. Another Parhae man named Gao Qinyi became the advisor of [[Wanyan Zonghan]], a Jurchen general and close friend of Aguda. An 1125 embassy noted that Jin protocol officers included Khitans, Jurchens, as well as Parhae. They all spoke Chinese.{{sfn|Sloane|2014|p=373}}<ref name="Kim2014"/> A descendant of the Parhae royal family, Da Gao (1086–1153), served in the Jin army and was given command of eight Parhae battalions in the war against the [[Song dynasty]]. One Parhae commander, Guo Yaoshi (active 1116–1132) fought in the Liao, Jin, and Song armies at one point or another.{{sfn|Sloane|2014|p=375}} The Parhae played a critical role in supporting [[Emperor Shizong of Jin]]'s accession to the throne.{{sfn|Sloane|2014|p=383}}

Families of Parhae descent were able to rise high in the Jin hierarchy, including Zhang Rulin (d. 1190) and Zhang Rubi (d. 1187), who were key advisers of Emperor Shizong, and Li Yin (''jinshi'' 1194, d. 1214), who died fighting against the [[Mongols]]. Parhae descendants also participated with success in the Jin imperial examinations. Many Parhae literati-officials such as Gao Kan (d. 1167), Gao Xian (''jinshi'' 1203), Zhang Rulin, Zhang Runeng, Zhang Ruwei (fl. 1150), Zhang Rufang, and Wang Tingyun (1151–1202) were entrusted as arbiters of culture and cultivated taste.{{sfn|Sloane|2014|p=384-385}} Wang Tingyun's family received literary distinctions. His eldest daughter became a [[Daoist]] priestess, named Congqing, and was a poet at the imperial court. Intermarriage between Parhae civil elites in the Jin dynasty was common. In 1190, Wang Ji identified two families he encountered in Liaodong as Parhae. Writing after the fall of the Jin dynasty in 1234, Liu Qi identified the military commander Li Ying as a "Bohai man of Liaodong."{{sfn|Sloane|2014|p=386}}

There were still limitations on Parhae people in the Jin dynasty. In 1136, the Jurchen official Wanyan Puluhu revoked the pardon of a man when his origin was determined to be Parhae. Policies to restrain and weaken Parhae were increased over time. In 1140, an edict abolished Han Chinese and Parhae hereditary military garrisons but not [[Kumo Xi]] and Khitan garrisons. The Jin government also targeted the Parhae population for relocation. Over the years, groups of Parhae who were once moved outside to areas near the Liao supreme or central capital regions were resettled east of the [[Taihang Mountains]], which was completed by 1141. Another relocation south of [[Zhongdu]] was planned in 1149, but the Parhae court attendant Gao Shouxing protested to [[Empress Daoping]], who told the emperor, resulting in the beating and death of the two officials planning the relocation.{{sfn|Sloane|2014|p=381}} A substantial Jin military presence was bought to Liaodong in which as many as thirty Jurchen meng'an units (''meng'an'' literally means ''one thousand'' or units composed of one thousand soldiers) and the families of the retinues were moved to garrisons in the Eastern Capital Circuit. The southward migration of Jurchens, especially Jurchen aristocrats, may have contributed to a decline of people who identified as Parhae.{{sfn|Sloane|2014|p=389-390}} In 1177, a decree was passed to abolish the "old Bohai custom" of marriage through mock abduction. Although the Parhae experienced less restrictions under the Jin, there was also less emphasis on Parhae as a distinct group. During the later Jin era, the strong association between Parhae and Liaodong declined as Liaodong became dominated by other identities.{{sfn|Sloane|2014|p=388-389}}

As Parhae descendants became firmly incorporated into the apparatus of the Jurchen-led state, many individual Parhae-descended officials willingly chose to self-identify as Chinese. In 1135, Nansali was chosen as an emissary to Goryeo, for which he changed his name to the Sinitic Wang Zheng. Wang Tingyun also invented a genealogy record on his epitaph tracing his lineage to [[Taiyuan]] rather than Liaodong. The epitaph acknowledges that his most recent ancestors were in the employ of Parhae but added that they only "lived dispersed among the eastern barbarians", rejecting his Parhae identity. The practice of inventing fictitious genealogies to hide ancestry outside of the "Central Territories" was widespread from Song times onward.{{sfn|Sloane|2014|p=390-391}}

====Mongol Empire====
The term "Parhae" became noticeably less prevalent under the rule of the [[Mongol Empire]]. There is no trace of Parhae descendants from the defunct Jin dynasty and no epitaphs from the Mongol era claim a Parhae identity.{{sfn|Sloane|2014|p=396-397}} Parhae was only used as a toponym in the early 14th century and Parhae disappeared entirely from historical sources by the late 14th century.{{sfn|Sloane|2014|p=396-398}} Near the end of Mongol rule, Tao Zongyi (c. 1316–1402) put Parhae alongside Khitan and Jurchen under a subcategory within [[Hanren]], which is not surprising given that most of them at the time of the Mongol conquest were literati, officials, or attachments to the Jin bureaucracy. Many chose to use Chinese style names, similar to Jurchens, probably for inclusion in the Hanren (Northern Chinese) category under the Mongol hierarchy, rather than the inferior fourth category, ''Nanren'' (Southern Chinese).{{sfn|Sloane|2014|p=392-394}} Aside from legal references to the ''Taihe Code'' of the Jin dynasty, the term "Parhae" is absent from the Yuan legal compendium.{{sfn|Sloane|2014|p=396-397}} The referenced passages have to do with limitations on levirate marriage for Han and Parhae and restrictions on marriage during mourning.{{sfn|Sloane|2014|p=397}}

Some Parhae adopted Mongol or [[Tatars|Tatar]] culture rather than Chinese. The biography of You Xingge (d. 1227) identifies him as Parhae. As the Jin dynasty was collapsing from the Mongol invasions, You established an independent fort near Gaozhou (modern [[Chifeng]]). They fought off several military detachments until they were besieged by [[Muqali]]. After You surrendered, Muqali praised him to [[Genghis Khan]], who bestowed on him the Mongol name Halabadu. He later fought for the Mongols at Taiyuan in 1227. You Xingge's son is only referred to by the name Mangqutai, which denotes him as part of the Mangqutai tribe.{{sfn|Sloane|2014|p=394-395}}

The decline of Parhae identity was not a gradual and steady process. According to Toyama Gunji, "the Bohai remained alive and well for three hundred years of history" after the state was destroyed.{{sfn|Sloane|2014|p=403}}

==Culture==
Parhae's population was composed of former Goguryeo people and Tungusic [[Mohe people|Mohe]] people in Manchuria. Within sixty sites identified as Parhae settlements, many had dwellings with heating stoves, ceramic roof tiles, and vessels. Iron agricultural implements suggest that sophisticated agriculture was practised in parts of Parhae. These finds indicate that much of the population even outside the capitals were sedentary.{{sfn|Sloane|2014|p=367}}

Parhae's culture is as complex as its ethnic makeup. Archaeological findings have demonstrated that Parhae culture contained elements from Mohe, Goguryeo, Turkic, as well as Tang Chinese cultures. However, scholars from Japan, China, Russia and Korea emphasize some components over the others because of their national backgrounds.<ref>Song, Ki-ho. 'Several Questions in Studies of the History of Palhae.' Korea Journal 30:6 (June 1990): 12.</ref> 

Han Ciu-cheol believes that many of Goguryeo's tradition were continued by Parhae, such as the use of [[Ondol]] heating systems in Parhae's royal palaces as well as the use of stone lined tombs, stone chambers and stone coffins used by Goguryeo's ruling class.<ref>{{cite book |last1=Han |first1= Ciu-cheol |chapter=The Ethnic Composition of Parhae’s Population|title=A New History of Parhae |date=2012 |publisher=Brill |page=22}}</ref> According to Japanese historian Shiratori Kurakichi, 26 of the 85 emissaries dispatched to Japan by Parhae bore the typical Goguryeo surname of Ko (Go), which is still commonly used in Korea, indicating a substantial Goguryeo presence in Parhae culture.<ref>{{cite book |last1=Duncan |first1=John |title=A New History of Parhae |date=2012 |publisher=Brill |page=16}}</ref>

A record of the journey of Hong Hao (1088–1155) in Jin territory describes the Parhae people as primarily martial and not adherent to Confucian norms. Parhae women were described as "fiercely jealous"{{sfn|Sloane|2014|p=378}} and prevented the men from deviating from martial fidelity. Parhae men were described as "full of cunning, surpassing other nations in courage, such that there exists a saying 'Three Bohai are a match for a tiger.'" Some Parhae people practiced Buddhism.{{sfn|Sloane|2014|p=378}} However Parhae cultural markers evidently did not deviate to the point of preventing assimilation into neighboring societies. There was widespread usage of "Chinese" style surnames in Parhae and no distinct cultural marker prevented them from integrating into Chinese literati society. There is no evidence of any friction in this process. Other cultural markers such as martial traditions may have also facilitated the adoption of Mongol, Tatar, and Jurchen backgrounds.{{sfn|Sloane|2014|p=402}}

==Society==
According to Korean scholars and other historians, Mohe made up the working class which served the Goguryeo ruling class.<ref name="Lee Ki-baik page 88–89" /><ref name="OwenMiller">{{cite book|last1=Injae|first1=Lee|last2=Miller|first2=Owen|last3=Jinhoon|first3=Park|last4=Hyun-Hae|first4=Yi|title=Korean History in Maps|publisher=Cambridge University Press|isbn=9781107098466|pages=64–65|url=https://books.google.com/books?id=46OTBQAAQBAJ&pg=PA64|access-date=24 February 2017|language=en|date=15 December 2014}}</ref> Some historians believe that ethnic conflicts between the ruling [[Goguryeo]]s and underclass Mohe weakened the state.<ref name="Lee Ki-baik page 88–89">Lee Ki-baik.

Han Ciu-cheol agreed that Mohe people were the majority of Parhae's population but disagreed that they were any different from Goguryeo or Parhae. According to Han, the origins of "Malgal" and "Mulgil" lie in the Goguryeo language, and "the Malgal language and customs were the same as those of Goguryeo and Balhae."{{sfn|Reckel|2015|p=482}}

On the other hand, the Russian historian Polutov believes that Goguryeo descendants did not have political dominance, and the ruling system was open to all people equally.<ref>{{cite web|url=https://cyberleninka.ru/article/n/gosudarstvennyy-apparat-korolevstva-bohay|title=Государственный аппарат королевства Бохай |trans-title=State apparatus of the kingdom of Bohai|author1=Polutov, Andrey Vadimovich |work= Siberian historical research|date=2014 |access-date=7 February 2019 }}</ref> Its ruling structure was based on the military leader-priestly management structure of the Mohe tribes and also partly adapted elements from the Chinese system.

The class system of Parhae society is controversial. Some studies suggest there was a stratified and rigid class system similar to those of the related Korean kingdoms and pre-[[Qin dynasty|Qin]] northern China. Elites tended to belong to large extended aristocratic family lines designated by surnames. The commoners in comparison had no surnames at all, and upward social mobility was virtually impossible as class and status were codified into a caste system.{{sfn|Crossley|1997|p=19}} Other studies have shown there was a clan system but no clear division of classes existed, whereas the position of the clan leader depended on the strength of the clan. Any member of the clan could become the clan leader if he had sufficient authority. There were also religiously privileged shaman clans. The clan struggles were also partly due to growing Tang influence and different attitudes toward further Sinicization. The main part of society in Parhae was free in a personal capacity and consisted of clans.<ref>{{cite web|url=https://cyberleninka.ru/article/n/k-voprosu-o-politicheskoy-situatsii-v-bohae-v-720-e-gg|title=К ВОПРОСУ О ПОЛИТИЧЕСКОЙ СИТУАЦИИ В БОХАЕ В 720-Е ГГ |trans-title=On the issue of the political situation in Bohai in the 720s|author=Kim, Alexander Alekseevich |work= BHumanitarian research in Eastern Siberia and the Far East |date=2013 |access-date=5 February 2019 }}</ref>

By the time of the state's demise, the Parhae mode of living had come to resemble that of the northern Chinese. The Liao dynasty classified the Parhae population as Han in legal and taxation contexts, the same as those whose ancestry was traced to the Tang empire. Some Mohe groups did not adopt this manner of life and were excluded from the Liao's designation of Parhae. Instead, they remained as Mohe, and would become an important source of the [[Jurchen people]] in the future.<ref name="Crossley 2016"/>

==Military==
Parhae's military organization consisted of a central army divided into ten guard units (wi, 衛) responsible for protecting the royal palace and the capital. Local militias were organized in the 15 local provinces (bu) for other regions according to the regional administrative structures, with local officials commanding them.<ref name="MSB">Military System of Balhae, [[War Memorial of Korea]]</ref> Independent troops were stationed at key border points for defense.

The development of Parhae's military system can be broadly divided into three phases. The first phase involved establishing administrative systems for the newly expanded territories during the early stages of the kingdom's founding. The second phase saw the establishment of the ten guards as recorded in the ''[[Xin Tangshu]]'' (New Book of Tang). In contrast, the third phase occurred after the envoy Wang Zhongwu reported on Parhae's military situation following his visit.

Parhae expanded its territory by conquering the [[Mohe people|Mohe]] (Malgal) tribes in Manchuria, Primorsky Krai, the Amur River region, and along the coast of the Sea of Japan, during which many fortresses were built. Some of these include the Palryeonseong, Mariyanovka Fortress, Cheonghaeto Fortress, Koksharovka Fortress Site, Kraskino Fortress Site, Nikolayevka Fortress Site in Partizansk, Suchanluha Fortress Site, Bittik Mountain Fortress Site, Ryuzanka Fortress Site, Usti-Chornaya Fortress Site, Namusurisk Fortress Site, Korsakovka Fortress Site, and Novgorodeyev Fortress Site.

=== First phase ===
The first phase was a period during which the overall system was established, and this period firmly retained the legacy of Goguryeo, with military and administrative functions often overlapping. Volume 193 of ''[[Ruijū Kokushi]]'' records that "Parhae spans 2,000 li in all directions, and no prefectures or counties exist. Villages are scattered throughout, mostly Malgal settlements. The people are mostly Malgal, and few are native. All the natives are made village chiefs, with large villages appointing a Dudu/Dudok (都督, Governor) and smaller ones appointing a Cishi/Jasa (刺史, Prefect), while the rest of the leaders are called Shouling/Suryong (首領, Chiefs)." The Dudok or Jasa were likely regional administrative officials of Parhae, such as the Yakheolju Dudok, Mokjeoju Jasa, and Hyeontoju Jasa. Since this was an early period when the system was still being established, remnants of the former Goguryeo dynasty's institutions were still present in many areas, and the division of the entire country was still incomplete. Therefore, in military terms, troops were dispatched mainly to tense situations.

Through the continued territorial expansion during the reigns of King Go and King Mu, Parhae's territorial boundaries were secured, and the government structure was reorganized and completed by acquiring territory, population, and tax revenues. Considering that the initial military force at the time of Parhae's founding was only a few thousand, Parhae likely needed to make overall adjustments to the expanded territory and population. Parhae, which had borders with powerful neighboring states like the Tang Dynasty, the Turks, the Khitans, the Heishui Mohe, and Silla, faced deteriorated relations with its neighbors due to its early aggressive conquests. Moreover, having witnessed the fall of Goguryeo, the dominant power in the previous era, Parhae needed to strengthen and reorganize its military. Therefore, this period can be seen as when Parhae laid the foundation for establishing a new system based on Goguryeo's legacy over the expanded territory.

=== Second phase ===
The second phase saw the establishment of central departments and the ten guards, as recorded in the ''New Book of Tang''. The Zhengtangsheng/Jeongdangseong (政堂省), one of the [[Three Departments and Six Ministries|three central departments]], managed the military, recruitment, maps, war chariots, and weapons through the subordinate department known as the Zhibu/Jibu (智部). Subordinate to the Jibu were practical departments such as the Rongbu/Yongbu (戎部) and Shuibu/Subu (水部). For example, Yang Seung-gyeong, who was sent as an envoy to Japan in 758, held the central position of Boguk Daejanggun and Janggun (輔國大將軍兼將軍) and the regional position of Mokjeoju Jasa (木底州刺史), and he was also involved in managing national defense. However, the origins of these titles are difficult to trace, as they do not appear in the central official system. This indicates that Parhae organized its military by establishing the Jibu as the central department responsible for military affairs and its subordinate departments like the Yongbu or the Byeongseo (兵書).

Parhae had ten guards, including the "Left and Right Mengbenwei/Mangbunwi (猛賁衛), Left and Right Xiongwei/Ungwi (熊衛), Left and Right Piwei/Biwi (羆衛), Left and Right Nanwei/Namwi (南衛), and Left and Right Beiwei/Bukwi (北衛)."<ref name="MSB"/> Each guard had a Da Jiangjun/Daejanggun (大將軍) and a Jiangjun/Janggun (將軍). This system was likely modeled after the Tang Dynasty's 16 or 12 guards. Each guard had one Daejanggun and one Janggun, equivalent to the Tang Dynasty's Shang Jiangjun (上將軍) and Jiangjun (將軍). The ten guards protected the royal family and oversaw the local militia. In 1960, a seal inscribed with "Tianmenjun/Cheonmungun's Seal" (天門軍之印), belonging to one of Parhae's military units, was discovered southwest of the royal city of Sanggyeong Yongcheonbu. The discovery of this seal suggests that the army under each guard was responsible for guarding the gates of the royal city.

Meanwhile, the ''[[Shoku Nihongi]]'' records that in 728, among the envoys sent to Japan, there were officials such as You Jiangjun/Yujanggun (游將軍) and Guoyi Duwei/Gwaidowi (果毅都尉) Dezhou/Deokju (徳周). The title Guoyi Duwei was adopted from the Tang Dynasty's military system. In the Tang Dynasty, the Weibu (衛部) and the Zhechongfu (折衝府) were part of the military system. The Zhechongfu was further divided into upper, middle, and lower levels, with each level having one Zhechong Duwei (折衝都尉) and two Guoyi Duwei (果毅都尉). The Guoyi Duwei of the upper level was equivalent to the 5th rank, the middle level to the 6th rank, and the lower level to the 6th rank. In Parhae, the existence of the Guoyi Duwei/Gwaidowi indicates that Parhae likely adopted the Tang Dynasty's military system and established local militias in the provinces.

In particular, the military titles of envoys sent to Japan during the early period of Parhae, such as Janggun (將軍) or Boguk Daejanggun (輔國大將軍), suggest that the military system was already being organized at that time. The Jasa was a local administrative official overseeing the province, and the Daejanggun and Janggun were the highest military positions. The presence of various military titles among these envoys indicates that the system was already in the process of being organized.

=== Third phase ===
The third phase occurred after the envoy Wang Zhongwu reported on Parhae's military situation following his visit. In 832, after returning from Parhae, Wang Zhongwu reported to [[Emperor Wenzong of Tang]] that "Parhae has Left and Right Shencejun/Shinchaekgun (神策軍), Left and Right Sanjun/Samgun (三軍), and 120 departments." This indicates that the military system had evolved from the early generals' system to the Left and Right ten guards, and by the time Wang Zhongwu returned from his mission, it had already been expanded and reorganized into the Left and Right Shinchaekgun, Left and Right Samgun, and 120 departments. The Sanjun in the Tang Dynasty referred to the Left Longwu (龍武), Left Shenwu (神武), and Left Yulin (羽林) armies, while the Right Sanjun referred to the Right Longwu, Right Shenwu, and Right Yulin. These six armies were all part of the Weijun (衛軍).

Based on Wang Zhongwu's report, it can be inferred that Parhae's military system also adopted the Tang Dynasty's model, with both Weijun and local militias (Fubing). The Tang Dynasty system had separate Weijun and Fubing units, numbering over 600 nationwide. Each unit had a Langjiang (郞將) and was placed under the control of the Zhuwei (諸衛). This strict and extensive military organization greatly influenced Parhae, establishing the ten guards and units like the Shencejun/Shinchaekgun.

No historical records explicitly state that Parhae adopted the Tang Dynasty's [[Fubing system]]. However, considering Parhae's long-term territorial expansion and the presence of military officials such as Jasa, Rangjang, Gwaidowi, and Byeoljang, it is likely that Parhae implemented a Fubing system. Additionally, the ''New Book of Tang'' mentions that "Parhae's Buyeo Province is located on the border with the Khitans, and strong troops are always stationed there to defend against the Khitans," suggesting that Parhae had local militias similar to the Tang Dynasty's Fubing system, which played a crucial role in securing the borders. Military titles such as Langjiang/Rangjang and Biejiang/Byeoljang (别將) emerged during King Tae Muye's reign, indicating that Parhae had already implemented an army system modeled after the Tang Dynasty with central and local forces.

The size of the military grew from a few thousand soldiers in the early days to tens of thousands in later periods. It is known that in its early years, during the reign of King Mu, Parhae held 100,000 troops, which is one-third of Goguryeo's 300,000-strong army.<ref name="MSB"/>  Naturally, during periods of military control combined with production and conquest, even the elderly, children, and all men in a household might have been conscripted to meet the demands of external wars.

==Economy and trade==
Under Parhae, the region's agriculture became much more widespread and well-developed than in previous centuries, especially in the north. [[Millet]], [[barley]], [[soy bean]]s and [[rice]] were the main type of crops cultivated in Parhae. Some of its specialized regional produce, such as rice, fermented beans, plums and pears, were much sought after. Fishing and hunting also remained important among Parhae people. Parhae also produced fine iron and copper wares, silk and linen textiles, and ceramics, including [[Sancai]] pottery developed under the influence of that of the [[Tang dynasty|Tang]].<ref>{{cite book |author1=战继发 |title=黑龙江屯垦史（第1卷） |date=2017 |publisher=[[Social Sciences Literature Press]] |location=北京 |isbn=9787520113977 |pages=51–55|url=https://books.google.com/books?id=jUxsEAAAQBAJ&pg=PA51}}</ref> Whaling was also done, albeit this was mostly done as tribute to the Tang.<ref name="日本"/>
