Editing Władysław II Jagiełło (section)

===Baptism and marriage===
{{see also|Jadwiga of Poland}}
Jogaila's Russian mother [[Uliana of Tver]] urged him to marry Sofia, daughter of [[Dmitri Donskoi|Prince Dmitri of Moscow]], who required him first to convert to Orthodoxy.<ref group=nb>The historian [[John Meyendorff]] suggests Jogaila may have already been an Orthodox Christian: "In 1377, Olgerd of Lithuania died, leaving the Grand Principality to his son Jagiello, an Orthodox Christian..." ({{harvnb|Meyendorff|1989|p=205}}). Dmitri, however, made it a condition of the marriage that Jogaila "should be baptized in the Orthodox faith and that he should proclaim his Christianity to all men" ({{harvnb|Dvornik|1992|p=221}}).</ref> That option, however, was unlikely to halt the crusades against Lithuania by the Teutonic Knights, who regarded [[Eastern Orthodox Church|Orthodox Christians]] as schismatics and little better than heathens.<ref name="Bojtar"/><ref name="Jones"/> Jogaila chose therefore to accept a Polish proposal to become a [[Catholic]] and marry the eleven-year-old Queen [[Jadwiga of Poland]].<ref group=nb>Jadwiga had actually been crowned [[king of Poland]] ({{lang|la|rex poloni}}), because the Polish political system made no provision for a [[queen regnant]] ({{harvnb|Stone|2001|p=8}}).</ref> The nobles of [[Lesser Poland]] made this offer to Jogaila for many reasons. They wanted to neutralize the dangers posed by Lithuania itself and to secure the fertile territories of [[Galicia–Volhynia]].<ref name="lukowski"/> The Polish nobles saw the offer as an opportunity for increasing their privileges<ref name="dvornik"/> and avoiding Austrian influence, brought by Jadwiga's previous fiancé [[William, Duke of Austria]].<ref name="lukowski2"/>

On 14 August 1385 in [[Kreva Castle]], Jogaila confirmed his prenuptial promises in the [[Union of Krewo]] (Union of Kreva). The promises included the adoption of Christianity, repatriation of lands "stolen" from Poland by its neighbours, and ''terras suas Lithuaniae et Russiae Coronae Regni Poloniae perpetuo applicare'', a clause interpreted by historians to mean anything from a [[personal union]] between Lithuania and Poland to a complete incorporation of Lithuania into Poland.<ref name="lukowski3"/> The agreement at Kreva has been described both as far-sighted and as a desperate gamble.<ref group=nb>It "reflects the exceptional far-sightedness of the political elites ruling both countries" ({{Harvnb|Kłoczowski|2000|p=55}}). It was "a desperate gamble by Jogaila to avert a seemingly inevitable subjugation" ({{Harvnb|Lukowski|Zawadzki|2001|p=38}})</ref>

Jogaila was duly baptized at the [[Wawel Cathedral]] in [[Kraków]] on 15 February 1386 and from then on formally used the name Władysław or Latin versions of it.<ref name="sruogien"/><ref group=nb>A Slavic name that roughly translates as ''glorious rule'', Władysław is often [[Latinization (literature)|Latinised]] into either Wladislaus or Ladislaus. The choice evoked both [[Władysław I the Elbow-high|Władysław I of Poland, the Elbow-high]], who was Queen Jadwiga's great-grandfather and unified the kingdom in 1320, and Saint [[Ladislaus I of Hungary]], a king who sided with the pope against the emperor [[Henry IV, Holy Roman Emperor|Henry IV]] and Christianised [[Transylvania]] ({{harvnb|Rowell|2000|pp=709–712}}).</ref> The marriage took place three days later, and on 4 March 1386 Jogaila was crowned King Władysław by archbishop [[Bodzanta]]. He was also to be legally adopted by Jadwiga's mother, [[Elizabeth of Bosnia]], so retaining the throne in the event of Jadwiga's death.<ref name="Jones"/> He was the first [[Lithuanians|Lithuanian]] to be crowned as the King of Poland.<ref name="Vle">{{cite web |last1=Gudavičius |first1=Edvardas |last2=Jučas |first2=Mečislovas |last3=Matulevičius |first3=Algirdas |title=Jogaila |url=https://www.vle.lt/straipsnis/jogaila/ |website=[[Visuotinė lietuvių enciklopedija]] |access-date=19 May 2021 |language=lt}}</ref> The royal baptism triggered the conversion of most of Jogaila's court and noblemen, as well as mass baptisms in Lithuanian rivers,<ref name="Kłoczowski">{{Harvnb|Kłoczowski|2000|pp=54–57}}</ref> a beginning of the final [[Christianization of Lithuania]]. Though the ethnic [[Lithuanian nobility]] were the main converts to Catholicism—both paganism and the Orthodox rite remained strong among the peasants—the king's conversion and its political implications created lasting repercussions for the history of both Lithuania and Poland.<ref name="Kłoczowski"/> On 22 February 1387, he banned Catholics from marriages with [[Orthodoxy|Orthodox]] and demanded those Orthodox who previously married with the Catholics to convert to Catholicism.<ref name="Vle"/>
