Editing Jadwiga of Poland (section)

=== Conflict with the Teutonic Knights (1395–99) ===

The relationship between Lithuania and the Teutonic Knights remained tense.{{sfn|Halecki|1991|pp=230–233}} Jadwiga and her Polish advisers invited the Grand Master, Konrad von Jungingen, to Poland to open new negotiations in June 1396.{{sfn|Halecki|1991|p=233}} Conflicts with Vladislaus of Opole and Siemowit of Masovia, who had not given up their claims to parts of Ruthenia and [[Cuyavia]], also intensified.{{sfn|Halecki|1991|pp=234–235}} To demonstrate that the territories were under Jadwiga's direct control, Władysław-Jogaila granted the [[Duchy of Belz]] (in Ruthenia) and [[Cuyavia]] to her in early 1397.{{sfn|Halecki|1991|p=235}} However, Jadwiga and her Polish advisers wanted to avoid a war with the Teutonic Order.{{sfn|Frost|2015|p=89}} In response, Władysław-Jogaila replaced most Polish "starostas" (aldermen) in Ruthenia with local Orthodox noblemen.{{sfn|Frost|2015|p=89}} According to German sources, Władysław-Jogaila and Vytautas jointly asked [[Pope Boniface IX]] to sanction Vytautas' coronation as king of Lithuania and Ruthenia.{{sfn|Frost|2015|p=89}}

Jadwiga and Jungingen met in [[Włocławek]] in the middle of June, but they did not reach a compromise.{{sfn|Halecki|1991|pp=236–237}} The Teutonic Order entrusted Vladislaus of Opole with the task of representing their claims to Dobrzyń against Jadwiga.{{sfn|Halecki|1991|p=237}} Jadwiga and her husband met Sigismund of Hungary, who had returned there after his catastrophic defeat in the [[Battle of Nicopolis]], on 14 July.{{sfn|Halecki|1991|pp=236, 238}} They seem to have reached a compromise because Sigismund offered to mediate between Poland, Lithuania and the Teutonic Knights.{{sfn|Halecki|1991|p=240}} On Jadwiga's request, Wenceslaus of Bohemia granted permission for the establishment of a college for Lithuanian students in Prague on 20 July 1397.{{sfn|Halecki|1991|p=247}} Jadwiga, who had spent "many sleepless nights" thinking of this project, according to herself, issued a charter of establishment for the college on 10 November.{{sfn|Halecki|1991|p=247}}

She opened new negotiations with the Teutonic Knights, but Konrad von Jungingen dispatched a simple knight to meet her in May 1398.{{sfn|Halecki|1991|p=241}} Władysław-Jogaila's cousin Vytautas also entered into negotiations with the Teutonic Knights because he wanted to unite Lithuania and Ruthenia under his rule and to receive a royal crown from the Holy See.{{sfn|Halecki|1991|pp=242–243}} According to the chronicle of [[John of Posilge]], who was an official of the Teutonic Order, Jadwiga sent a letter to Vytautas, reminding him to pay the annual tribute that Władysław-Jogaila had granted her as [[dower]].{{sfn|Frost|2015|p=89}}{{sfn|Halecki|1991|pp=243–244}} Offended by Jadwiga's demand, Vytautas sought the opinion of the Lithuanian and Ruthenian lords who refused Jadwiga's claim to a tribute.{{sfn|Frost|2015|p=89}} On 12 October 1398, he signed a peace treaty with the Teutonic Knights, without referring to Władysław-Jogaila's right to confirm it.{{sfn|Halecki|1991|pp=242–243}} Oscar Halecki says that Posilge's "sensational story" is either an invention based on gossip or a guess by the chronicler.{{sfn|Halecki|1991|p=244}}
