From Tvrtko I, Dabiša also inherited the hostility of the Hungarian king, who strived to recover the territories lost to Tvrtko. Sigismund's wish to have his war against Bosnia equated to a crusade obtained Pope Boniface IX's approval. Dabiša was Roman Catholic, but a substantial population of his kingdom consisted of adherents of the Bosnian Church and the Serbian Orthodox Church, branded "heretics and schismatics" respectively in Sigismund's letter to Boniface. It is not known what came about this planned offensive. In the spring of 1392, Dabiša's troops defeated an Ottoman Turkish incursion, reminiscing Tvrtko's victory at the Battle of Bileća. Within a year, Dabiša and Sigismund had agreed to a truce.
