The First Peace of Thorn of 1411 had ostensibly ended conflicts between the warring powers of the Polish-Lithuanian–Teutonic War, although the border between Samogita and Prussia was not determined. Poland also contested Pomerania, Pomerelia, and Culmerland (Chełmno Land). When numerous attempts at negotiations failed, a brief Hunger War broke out in summer 1414. Since Poles and Lithuanians were unable to capture strongly fortified Ordensburgen of the Knights, parties agreed to mediate their dispute in the Council of Constance. The Council established Samogitian Diocese in Varniai and appointed Matthias of Trakai as its first bishop. However, it did not solve the underlying territorial disputes by the time it ended in 1418.
