In 1411, the
First Peace of Thorn ended the
Polish–Lithuanian–Teutonic War, in which the
Teutonic Knights fought the
Kingdom of Poland and
Grand Duchy of Lithuania. However, the peace was not stable and further conflicts arose regarding demarcation of the
Samogitian borders. The tensions erupted into the brief
Hunger War in summer 1414. It was concluded that the disputes would be mediated by the Council of Constance. The Polish-Lithuanian position was defended by
Paulus Vladimiri, rector of the
Jagiellonian University, who challenged legality of the Teutonic
crusade against Lithuania. He argued that a forced conversion was incompatible with free will, which was an essential component of a genuine conversion. Therefore, the Knights could only wage a defensive war if pagans violated
natural rights of the Christians. Vladimiri further stipulated that infidels had rights which had to be respected, and neither the Pope nor the
Holy Roman Emperor had the authority to violate them. Lithuanians also brought a group of Samogitian representatives to testify to atrocities committed by the Knights. The Dominican theologian
John of Falkenberg proved to be the fiercest opponent of the Poles. In his
Liber de doctrina, Falkenberg argued thatthe Emperor has the right to slay even peaceful infidels simply because they are pagans. ... The Poles deserve death for defending infidels, and should be exterminated even more than the infidels; they should be deprived of their sovereignty and reduced to slavery. In
Satira, he attacked Polish-Lithuanian King
Jogaila, calling him a "mad dog" unworthy to be king. Falkenberg was condemned and imprisoned for such libel. Other opponents included
Grand Master's proctor Peter Wormditt, Dominic of San Gimignano, John Urbach, Ardecino de Porta of Novara, and
Bishop of Ciudad Rodrigo Andrew Escobar. They argued that the Knights were perfectly justified in their crusade as it was a sacred duty of Christians to spread the true faith. Cardinal
Pierre d'Ailly published an independent opinion that attempted to somewhat balance both Polish and Teutonic positions. The council established the
Diocese of Samogitia, with its seat in
Medininkai and subordinated to Lithuanian dioceses, and appointed
Matthias of Trakai as the first bishop. Pope Martin V appointed the Lithuanians
Jogaila and
Vytautas, who were respectively King of Poland and Grand Duke of Lithuania, as
vicars general in
Pskov and
Veliky Novgorod in recognition of their Catholicism. After another round of futile negotiations, the
Gollub War broke out in 1422. It ended with the
Treaty of Melno. Polish-Lithuanian-Teutonic wars continued for another hundred years. ==Later status==
