'''Louis I''', also known as '''Louis the Great''' ({{langx|hu|Nagy Lajos}}; {{langx|hr|Ludovik Veliki}}; {{langx|sk|Ľudovít Veľký}}) or '''Louis the Hungarian''' ({{langx|pl|Ludwik Węgierski}}; 5 March 1326{{spaced ndash}}10 September 1382), was [[King of Hungary]] and [[King of Croatia|Croatia]] from 1342 and [[King of Poland]] from 1370 until his death in 1382. He was the first child of [[Charles I of Hungary]] and his wife, [[Elizabeth of Poland, Queen of Hungary|Elizabeth of Poland]], to survive infancy. A 1338 treaty between his father and [[Casimir III of Poland]], Louis's maternal uncle, confirmed Louis's right to inherit the [[Kingdom of Poland (1025–1385)|Kingdom of Poland]] if his uncle died without a son. In exchange, Louis was obliged to assist his uncle to reoccupy the lands that Poland had lost in previous decades. He bore the title [[Duke of Transylvania]] between 1339 and 1342 but did not administer the province.

Louis was of age when he succeeded his father in 1342, but his deeply religious mother exerted a powerful influence on him. He inherited a centralized kingdom and a rich treasury from his father. During the first years of his reign, Louis launched a [[Lithuanian Crusade|crusade]] against the [[Lithuanians]] and restored royal power in [[Kingdom of Croatia (1102–1526)|Croatia]]; his troops defeated a [[Tatars|Tatar]] army, expanding his authority towards the [[Black Sea]]. When his brother, [[Andrew, Duke of Calabria]], husband of Queen [[Joanna I of Naples]], was assassinated in 1345, Louis accused the queen of his murder and punishing her became the principal goal of his foreign policy. He launched two campaigns to the [[Kingdom of Naples]] between 1347 and 1350. His troops occupied large territories on both occasions, and Louis adopted the styles of [[King of Naples|Neapolitan sovereigns]] (including the title of King of Sicily and [[King of Jerusalem#Claimant kings of Jerusalem (1291 until today)|Jerusalem]]), but the [[Holy See]] never recognized his claim. Louis's arbitrary acts and atrocities committed by his mercenaries made his rule unpopular in [[Southern Italy]]. He withdrew all his troops from the Kingdom of Naples in 1351.

Like his father, Louis administered Hungary with absolute power and used [[royal prerogative]]s to grant privileges to his courtiers. However, he also confirmed the liberties of the [[Hungarian nobility]] at the [[Diet of Hungary|Diet]] of 1351, emphasizing the equal status of all noblemen. At the same Diet, he introduced an [[Fee tail|entail]] system and a uniform rent payable by the peasants to the landowners, and confirmed the right to free movement for all peasants. He waged wars against the Lithuanians, [[Serbian Empire|Serbia]], and the [[Golden Horde]] in the 1350s, restoring the authority of Hungarian monarchs over territories along frontiers that had been lost during previous decades. He forced the [[Republic of Venice]] to renounce the [[Dalmatia]]n towns in 1358. He also made several attempts to expand his suzerainty over the rulers of [[Banate of Bosnia|Bosnia]], [[Principality of Moldavia|Moldavia]], [[Principality of Wallachia|Wallachia]], and parts of [[Second Bulgarian Empire|Bulgaria]] and Serbia. These rulers were sometimes willing to yield to him, either under duress or in the hope of support against their internal opponents, but Louis's rule in these regions was only nominal during most of his reign. His attempts to convert his pagan or Orthodox subjects to Catholicism made him unpopular in the Balkan states. Louis established a university in [[Pécs]] in 1367, but it was closed within two decades because he did not arrange for sufficient revenues to maintain it.

Louis inherited Poland after his uncle's death in 1370. Since he had no sons, he wanted his subjects to acknowledge the right of his daughters to succeed him in both Hungary and Poland. For this purpose, he issued the [[Privilege of Koszyce]] (now [[Košice]] in Slovakia) in 1374 spelling out the liberties of [[Polish noblemen]]. However, his rule remained unpopular in Poland. In Hungary, he authorized the [[royal free cities]] to delegate jurors to the high court hearing their cases and set up a new high court. Suffering from a [[skin disease]], Louis became even more religious during the last years of his life. At the beginning of the [[Western Schism]], he acknowledged [[Urban VI]] as the legitimate [[pope]]. After Urban deposed Joanna and put Louis's relative [[Charles III of Naples|Charles of Durazzo]] on the throne of Naples, Louis helped Charles occupy the kingdom. In Hungarian historiography, Louis was regarded for centuries as the most powerful Hungarian monarch who ruled over an empire "whose shores were washed by three seas".

[[File:Ludvik1Uhersko.jpg|thumb|alt=A crowned woman lying in a bed and stretches her hands towards a crowned baby held by a woman |Louis's birth depicted in the ''[[Chronicon Pictum|Illuminated Chronicle]]'']]

Born on 5 March 1326,{{sfn|Csukovits|2012|p=116}} Louis was the third son of [[Charles I of Hungary]] and his wife, [[Elizabeth of Poland, Queen of Hungary|Elizabeth of Poland]].{{sfn|Kristó|2003|p=45}} He was named for his father's uncle, [[Louis of Toulouse|Louis]], [[Bishop of Toulouse]], [[canonized]] in 1317.{{sfn|Kristó|2003|pp=45–46}} The first-born son of his parents, Charles, died before Louis was born.{{sfn|Kristó|2003|p=45}} Louis became his father's heir after the death of his brother Ladislaus in 1329.{{sfn|Kristó|2003|pp=45, 47}}

He had a liberal education by the standards of his age and learned French, German and Latin.{{sfn|Cartledge|2011|p=36}} He showed a special interest in history and [[astrology]].{{sfn|Csukovits|2012|p=116}}{{sfn|Engel|2001|p=158}} A cleric from [[Wrocław]], [[Nicholas Neszmélyi|Nicholas]], taught him the basic principles of Christian faith.{{sfn|Bertényi|1989|p=48}} However, Louis's religious zeal was due to his mother's influence.{{sfn|Engel|2001|p=170}} In a royal charter, Louis remembered that in his childhood, a knight of the royal court, Peter Poháros, often carried him on his shoulders.{{sfn|Bertényi|1989|p=48}}{{sfn|Kristó|2003|p=47}} His two tutors, [[Nicholas I Drugeth|Nicholas Drugeth]] and Nicholas Tapolcsányi, saved the lives of both Louis and his younger brother, [[Andrew, Duke of Calabria|Andrew]], when [[Felician Záh]] attempted to assassinate the royal family in [[Visegrád]] on 17 April 1330.{{sfn|Bertényi|1989|p=48}}{{sfn|Solymosi|Körmendi|1981|p=201}}

Louis was only nine when he stamped a treaty of alliance between his father and [[John of Bohemia]].{{sfn|Kristó|2003|p=47}}{{sfn|Knoll|1972|p=74}} A year later, Louis accompanied his father in invading [[Duchy of Austria|Austria]].{{sfn|Kristó|2003|p=48}}{{sfn|Bertényi|1989|p=50}} On 1 March 1338, John of Bohemia's son and heir, [[Charles IV, Holy Roman Emperor|Charles]], [[Margrave of Moravia]], signed a new treaty with Charles I of Hungary and Louis in [[Visegrád]].{{sfn|Bertényi|1989|p=50}}{{sfn|Knoll|1972|p=95}} According to the treaty, Charles of Moravia acknowledged the right of Charles I's sons to succeed their maternal uncle, [[Casimir III of Poland]], if Casimir died without a male issue.{{sfn|Bertényi|1989|p=51}} Louis also pledged that he would marry the margrave's three-year-old daughter, [[Margaret of Bohemia, Queen of Hungary|Margaret]].{{sfn|Bertényi|1989|p=51}}

Casimir III's first wife, [[Aldona of Lithuania]], died on 26 May 1339.{{sfn|Knoll|1972|p=97}} Two leading [[Szlachta|Polish noblemen]]{{spaced ndash}}Zbigniew, chancellor of Kraków, and [[Spycimir Leliwita]]{{spaced ndash}}persuaded Casimir, who had not fathered a son, to make his sister, Elizabeth, and her offspring his heirs.{{sfn|Knoll|1972|pp=97–98}} According to the 15th-century [[Jan Długosz]], Casimir held a [[general sejm]] in [[Kraków]] where "the assembled prelates and nobles"<ref name="Długosz_1339_p289">''The Annals of Jan Długosz'' (A.D. 1339), p. 289.</ref> proclaimed Louis as Casimir's heir, but the reference to the sejm is anachronistic.{{sfn|Knoll|1972|p=98}} Historian Paul W. Knoll writes that Casimir preferred his sister's family to his own daughters or a member of a [[cadet branch]] of the [[Piast dynasty]], because he wanted to ensure the king of Hungary's support against the [[Teutonic Knights]].{{sfn|Knoll|1972|p=98}} Louis's father and uncle signed a treaty in [[Visegrád]] in July whereby Casimir III made Louis his heir if he died without a son.{{sfn|Solymosi|Körmendi|1981|p=206}} In exchange, Charles I pledged that Louis would reoccupy [[Pomerania]] and other Polish lands lost to the [[Teutonic Order]] without Polish funds and would only employ Poles in the royal administration in Poland.{{sfn|Knoll|1972|p=98}}

Louis received the title of [[Duke of Transylvania]] from his father in 1339, but he did not administer the province.{{sfn|Kristó|2003|p=48}}{{sfn|Engel|2001|p=157}} According to a royal charter from the same year, Louis's bride, [[Margaret of Bohemia, Queen of Hungary|Margaret of Bohemia]], lived in the Hungarian royal court.{{sfn|Kristó|2003|p=48}} Louis's separate ducal court was first mentioned in a royal charter of 1340.{{sfn|Kristó|2003|p=48}}

=== First years (1342–1345)===
[[File:The Secretum Secretorum (The Secret of Secrets) - Louis the Great of Hungary.jpg|alt=King Louis I of Hungary, crown, shield, Anjou coat of arms, secpter, Hungarian, medieval, book, illumination, illustration, history|left|thumb|King Louis I as depicted in the ''Secretum Secretorum'' (Secret of Secrets)]]
[[File:Karolus Moravius.jpg|thumb |upright |alt=A young man wearing a ducal crown with a flag in his hand |[[Charles IV, Holy Roman Emperor|Charles, Margrave of Moravia]] (the future Charles IV, Holy Roman Emperor), the father of Louis's first wife, [[Margaret of Bohemia, Queen of Hungary|Margaret of Bohemia]] (from the ''[[Gelnhausen Codex]]'')]]
Charles I died on 16 July 1342.{{sfn|Engel|2001|p=138}} Five days later, [[Csanád Telegdi]], Archbishop of [[Archdiocese of Esztergom|Esztergom]], crowned Louis king with the [[Holy Crown of Hungary]] in [[Székesfehérvár]].{{sfn|Bertényi|1989|p=52}} Although Louis had attained the age of majority, his mother Elizabeth "acted as a sort of co-regent" for decades, because she exerted a powerful influence on him.{{sfn|Engel|2001|p=171}} Louis inherited a rich treasury from his father, who had strengthened royal authority and ruled without holding [[Diet of Hungary|Diets]] during the last decades of his reign.{{sfn|Engel|2001|pp=140, 157}}

Louis introduced a new system of land grants, excluding the grantee's brothers and other kinsmen from the donation in contrast with customary law: such estates [[escheat]]ed to the Crown if the grantee's last male descendants died.{{sfn|Engel|2001|p=178}} On the other hand, Louis often "[[Prefection|promoted a daughter to a son]]", that is authorized a daughter to inherit her father's estates, although customary law prescribed that the landed property of a deceased nobleman who had no sons was to be inherited by his kinsmen.{{sfn|Engel|2001|pp=178–179}} Louis often granted this privilege to the wives of his favorites.{{sfn|Engel|2001|p=179}} Louis also frequently [[jus gladii|authorized landowners to apply capital punishment]] in their estates, limiting the authority of the magistrates of the [[County (Kingdom of Hungary)|counties]].{{sfn|Engel|2001|p=180}}

[[William Drugeth]], an influential advisor of Louis's late father, died in September 1342.{{sfn|Solymosi|Körmendi|1981|p=207}} He bequeathed his landed property to his brother, Nicholas, but Louis confiscated those estates.{{sfn|Engel|2001|p=182}}{{sfn|Bertényi|1989|p=54}} In late autumn, Louis dismissed his father's [[Voivode of Transylvania]], [[Thomas Szécsényi]], although Szécsényi's wife was a distant cousin of the [[queen mother]].{{sfn|Bertényi|1989|p=54}}{{sfn|Kristó|2003|p=49}} Louis especially favored the [[Lackfi]]s: eight members of the family held high offices during his reign.{{sfn|Engel|2001|p=182}}{{sfn|Bertényi|1989|p=54}} [[Andrew Lackfi]] was the commander of the royal army during the first war of Louis's reign.{{sfn|Kristó|1988|p=91}} In late 1342 or early 1343, he invaded [[Serbian Empire|Serbia]] and restored the [[Banate of Macsó]], which had been lost during his father's reign.{{sfn|Bertényi|1989|p=56}}{{sfn|Kristó|1988|pp=91–92}}

[[Robert the Wise]], [[King of Naples]], died on 20 January 1343.{{sfn|Goldstone|2009|p=182}} In his [[Will and testament|testament]], he declared his granddaughter, [[Joanna I of Naples|Joanna I]], his sole heir, excluding Louis's younger brother, Andrew, Joanna's husband, from becoming co-ruler.{{sfn|Goldstone|2009|p=182}} Louis and his mother regarded this as an infringement of a previous agreement between the late kings of Naples and Hungary.{{sfn|Bertényi|1989|p=55}} He visited his bride's father, [[Charles IV, Holy Roman Emperor|Charles of Moravia]], in [[Prague]] to persuade him to intervene on Andrew's behalf with Charles's former tutor, [[Pope Clement VI]], the overlord of the [[Kingdom of Naples]].{{sfn|Bertényi|1989|p=55}}{{sfn|Kristó|2003|pp=49–50}} Louis also sent envoys to his Neapolitan relatives and the high officials of the kingdom, urging them to promote his brother's interests.{{sfn|Bertényi|1989|p=55}} Their mother, Elizabeth, left for Naples in the summer, taking with her almost the whole royal treasure, including more than {{convert|6628|kg|lb}} of silver and {{convert|5150|kg|lb}} of gold.{{sfn|Goldstone|2009|pp=76–77}}{{sfn|Engel|2001|pp=156, 159}} During her seven-month-long stay in Italy, she was only able to persuade her daughter-in-law and the pope to promise that Andrew would be crowned as Joanna's husband.{{sfn|Bertényi|1989|p=57}}

According to the nearly contemporaneous chronicle of [[John of Küküllő]], Louis launched his first campaign against a group of [[Transylvanian Saxons]], who had refused to pay taxes, and forced them to yield in the summer of 1344.{{sfn|Kristó|1988|pp=91, 94}} During his stay in Transylvania, [[Nicholas Alexander of Wallachia|Nicholas Alexander]]{{spaced ndash}}who was the son of [[Basarab I of Wallachia|Basarab]], the ruling [[prince of Wallachia]]{{spaced ndash}}swore loyalty to Louis on his father's behalf in [[Brașov|Brassó]] (now Brașov in [[Romania]]); thus the suzerainty of the Hungarian monarchs over [[Wallachia]] was, at least outwardly, restored.{{sfn|Solymosi|Körmendi|1981|p=208}}{{sfn|Sălăgean|2006|p=195}}{{sfn|Kristó|1988|pp=93–94}}

Louis joined a [[Northern crusades|crusade]] against the pagan [[Lithuanians]] in December 1344.{{sfn|Solymosi|Körmendi|1981|p=208}}{{sfn|Housley|1984|p=194}} The crusaders{{spaced ndash}}including [[John of Bohemia]], Charles of Moravia, [[Peter I, Duke of Bourbon|Peter of Bourbon]], and [[William II, Count of Hainaut|William of Hainaut and Holland]]{{spaced ndash}} laid siege to [[Vilnius]].{{sfn|Solymosi|Körmendi|1981|p=208}}{{sfn|Housley|1984|p=194}} However, a Lithuanian invasion of the lands of the Teutonic Knights forced them to lift the siege.{{sfn|Bertényi|1989|p=57}} Louis returned to Hungary in late February 1345.{{sfn|Solymosi|Körmendi|1981|p=208}} He dispatched [[Andrew Lackfi]], [[Count of the Székelys]], to invade the lands of the [[Golden Horde]] in retaliation for the [[Tatars]]' earlier plundering raids against [[Transylvania]] and the [[Szepesség]] (now Spiš in Slovakia).{{sfn|Kristó|1988|pp=96–97}}{{sfn|Bertényi|1989|p=58}} [[Andrew Lackfi|Lackfi]] and his army of mainly [[Székelys|Székely]] warriors inflicted a defeat on a large [[Tatars|Tatar]] army on 2 February 1345.{{sfn|Kristó|1988|pp=96–97}}{{sfn|Sălăgean|2006|p=199}} Hungarian warriors were victorious in their campaign, decapitating the local [[Tatars|Tatar]] leader, the brother-in-law of the Khan, Atlamïş, and making the [[Tatars]] flee toward the coastal area. The [[Golden Horde]] was pushed back behind the [[Dniester|Dniester River]], thereafter the [[Golden Horde|Golden Horde's]] control of the lands between the [[Eastern Carpathians]] and the [[Black Sea]] weakened.{{sfn|Kristó|1988|pp=96–97}}{{sfn|Sălăgean|2006|p=199}} A conflict between Louis's uncle and father-in-law (Casimir III of Poland and Charles of Moravia) led to a war between Poland and Bohemia in April.{{sfn|Kristó|1988|pp=95–96}} In this war Louis supported his uncle with reinforcements in accordance with the agreement of 1339.{{sfn|Kristó|1988|pp=95–96}}

While Louis's armies were fighting in Poland and against the Tatars, Louis marched to [[Kingdom of Croatia (1102–1526)|Croatia]] in June 1345{{sfn|Kristó|1988|p=98}} and besieged [[Knin]], the former seat of the late [[Ivan I Nelipac|Ivan Nelipac]], who had successfully resisted Louis's father, forcing [[Vladislava Kurjaković|his widow]] and son to surrender.{{sfn|Fine|1994|p=339}} The [[Kurjaković family|counts of Corbavia]] and other Croatian noblemen also yielded to him during his stay in Croatia.{{sfn|Kristó|1988|p=100}}{{sfn|Engel|2001|p=162}} The citizens of [[Zadar]] rebelled against the [[Republic of Venice]] and accepted his suzerainty.{{sfn|Fine|1994|p=339}}{{sfn|Magaš|2007|p=60}} Louis meanwhile returned to [[Visegrád]]. He dispatched [[Stephen II, Ban of Bosnia]], to assist the burghers of Zadar, but the ban did not fight against the Venetians.{{sfn|Kristó|1988|pp=103–104}}

Louis's brother Andrew was murdered in [[Aversa]] on 18 September 1345.{{sfn|Engel|2001|p=159}} Louis and his mother accused Queen Joanna I, [[Robert, Prince of Taranto|Prince Robert of Taranto]], [[Charles, Duke of Durazzo|Duke Charles of Durazzo]], and other members of the Neapolitan branches of the [[Capetian House of Anjou]] of plotting against Andrew.{{sfn|Engel|2001|p=159}}{{sfn|Goldstone|2009|pp=120–121}} In his letter of 15 January 1346 to [[Pope Clement VI]], Louis demanded that the pope dethrone the "husband-killer" queen in favor of [[Charles Martel, Duke of Calabria#Son of Joanna I of Naples|Charles Martel]], her infant son by Andrew.{{sfn|Goldstone|2009|pp=120–121}} Louis also laid claim to the regency of the kingdom during the minority of his nephew, referring to his patrilinear descent from the [[Charles Martel of Anjou|first-born son]] of Robert the Wise's father, [[Charles II of Naples]].{{sfn|Goldstone|2009|p=121}} He even promised to increase the amount of yearly tribute that the kings of Naples would pay to the [[Holy See]].{{sfn|Goldstone|2009|p=121}} After the pope failed to fully investigate Andrew's murder, Louis decided to invade southern Italy.{{sfn|Kontler|1999|p=93}} In preparation for the invasion, he sent his envoys to [[Ancona]] and other Italian towns before summer 1346.{{sfn|Kristó|1988|pp=109–110}}

While his envoys negotiated in Italy, Louis marched to Dalmatia to relieve Zadar, but the Venetians bribed his commanders.{{sfn|Kristó|1988|pp=104–105}}{{sfn|Bertényi|1989|p=61}} When the citizens broke out and attacked the besiegers on 1 July, the royal army failed to intervene, and the Venetians overcame the defenders outside the walls of the town.{{sfn|Bertényi|1989|p=61}}{{sfn|Kristó|1988|p=105}} Louis withdrew but refused to renounce Dalmatia, although the Venetians offered to pay 320,000 golden florins as compensation.{{sfn|Bertényi|1989|p=61}} Lacking military support from Louis, however, Zadar surrendered to the Venetians on 21 December 1346.{{sfn|Solymosi|Körmendi|1981|p=209}}

According to the {{ill|Chronicle of Parthénope|it|Cronaca di Partenope|italic=yes}}, the Neapolitan princes whom Louis had imprisoned during his first campaign in Southern Italy proposed that he marry Queen Joanna I's younger sister and heir, [[Maria of Calabria|Mary]].{{sfn|Goldstone|2009|p=171}} She was the widow of Charles of Durazzo, who had been executed on Louis's orders.{{sfn|Goldstone|2009|p=171}} During the siege of Aversa in the summer of 1350, Louis met her envoy in the nearby [[Trentola-Ducenta]] and the terms of their marriage were accepted.{{sfn|Goldstone|2009|p=171}} However, Mary was forced to marry Robet of Baux after Louis left Southern Italy.{{sfn|Goldstone|2009|pp=171, 175}}

Louis married his second wife, [[Elizabeth of Bosnia|Elizabeth]], around 20 June 1353.{{sfn|Solymosi|Körmendi|1981|p=213}} Elizabeth was the daughter of [[Stephen II, Ban of Bosnia]], and Stephen's wife, [[Elizabeth of Kuyavia]].{{sfn|Halecki|1991|p=365}}{{sfn|Bertényi|1989|p=89}} Louis and his new wife were within the [[prohibited degree of kinship]], because Louis's mother and his wife's grandmother were cousins,{{sfn|Halecki|1991|pp=365–366}} but they applied for a [[Dispensation (canon law)|papal dispensation]] only about four months after their marriage.{{sfn|Bertényi|1989|p=89}} Historian Iván Bertényi says that this haste suggests that Elizabeth, who had been living in the court of Louis's mother, was pregnant at the time of the marriage.{{sfn|Bertényi|1989|p=89}} If this theory is valid, Louis's and his wife's first child was [[Stillbirth|stillborn]].{{sfn|Bertényi|1989|p=89}} Their next child, [[Catherine of Hungary (1370–1378)|Catherine]], was born in 1370 and died in 1378.{{sfn|Engel|2001|p=169}}{{sfn|Bertényi|1989|p=89}} The next daughter, [[Mary, Queen of Hungary|Mary]], who would succeed Louis in Hungary, was born in 1371.{{sfn|Engel|2001|pp=169, 195}} Louis's youngest daughter, [[Jadwiga of Poland|Jadwiga]], who was born in 1373, became queen regnant of Poland.{{sfn|Kristó|2003|p=205}}

== Legacy ==

Louis was the only Hungarian monarch to receive the epithet "[[Greatness|Great]]".{{sfn|Cartledge|2011|p=36}} He was mentioned under this byname not only in Hungarian chronicles in the 14th and 15th centuries, but also in a 17th-century genealogy of the [[Capetians]].{{sfn|Bertényi|1989|p=154}} Both his chivalrous personality and his successful military campaigns contributed to the development of his fame as a "great king".{{sfn|Cartledge|2011|p=36}} Louis waged wars in almost each year during his reign.{{sfn|Engel|2001|p=158}} Louis "always desired peace at home and war abroad for neither can be made without the other", according to [[Antonio Bonfini]]'s late 15th-century chronicle.{{sfn|Csukovits|2012|p=116}} Historian Enikő Csukovits writes that Louis's military actions show that he continued and accomplished his father's policy through recovering Croatia and Dalmatia and waging wars in Southern Italy, in Lithuania and in the Balkan Peninsula.{{sfn|Csukovits|2012|p=117}} On the other hand, Pál Engel says that Louis's "expeditions often lacked a realistic goal and sometimes even a reasonable {{nobr|pretext ...}} it was war itself that gave him pleasure".{{sfn|Engel|2001|p=158}}

In the age of [[Romantic nationalism]], Hungary during Louis's reign was described as an empire "whose shores were washed by three seas" in reference to the [[Adriatic Sea|Adriatic]], [[Baltic Sea|Baltic]] and [[Black Sea]]s.{{sfn|Kontler|1999|p=93}}{{sfn|Cartledge|2011|p=41}} For instance, in 1845 the poet [[Sándor Petőfi]] referred to Louis's reign as a period when "the falling stars of the north, the east and the south were all extinguished in Hungarian seas".{{sfn|Engel|2001|p=167}} Poland remained an independent country during Louis's reign and its borders did not extend to the Baltic Sea, and Louis's suzerainty along the northwestern shores of the Black Sea was also uncertain.{{sfn|Kontler|1999|p=93}}

In Polish historiography, two contrasting evaluations of Louis's reign in Poland coexisted.{{sfn|Kłoczowski|1986|p=138}} The "pessimistic" tradition can be traced back to the views of the late 14th-century [[Jan of Czarnków]], who was banished from Poland during Louis's reign.{{sfn|Kłoczowski|1986|pp=132, 138}} Czarnków emphasized that "there was no stability in the Kingdom of Poland" and the royal officials "continually pillaged the property of the poor people" during Louis's reign.{{sfn|Kłoczowski|1986|p=135}} According to the "optimistic" historiographic tradition, Louis continued Casimir the Great's policy of preserving the unity of Poland against the separatist magnates of [[Greater Poland]] with the assistance of lords from [[Lesser Poland]].{{sfn|Kłoczowski|1986|p=139}}

John of Küküllő emphasized that Louis "ruled neither with passion, nor with arbitrariness, but rather as the guardian of righteousness".{{sfn|Cartledge|2011|p=41}} Antonio Bonfini also described Louis as a just king wandering among his subjects in disguise to protect them the royal officials' arbitrary acts.{{sfn|Csukovits|2012|pp=116–117}} Even Jan of Czarnków underlined that Louis "did not rule in an absolute manner; on the contrary, the foundations ... of [the Poles'] freedom were laid by him".{{sfn|Kłoczowski|1986|p=129}}

New palaces and castles built at [[Zólyom]], [[Diósgyőr]] and Louis's other favorite hunting places were "masterpieces of the highest European standards" of his age, according to historian László Kontler.{{sfn|Kontler|1999|p=99}} Louis initiated the compellation of the ''[[Illuminated Chronicle]]'', which preserved the text of earlier chronicles.{{sfn|Engel|2001|pp=158–159}} The 147 miniatures decorating the ''Illuminated Chronicle'' testify the mastery of Hungarian workshops during Louis's reign.{{sfn|Engel|2001|p=159}}{{sfn|Kontler|1999|p=100}}
