Answer based on context:

The threat of new religious persecution in Bosnia reappared within a few years of the war. Pope Innocent IV began urging the Hungarians to undertake another crusade in late 1246 and 1247, and they appeared willing. Matthew Ninoslav argued that he only associated with heretics to defend Bosnia against Hungarian invaders. He appears to have convinced Innocent, who suspended the crusade in March 1248. A crusade against Bosnia was preached again in 1337-38 and 1367, by popes Benedict XII and Urban V respectively, but in drastically different political circumstances. Hungary was ruled by a new dynasty, the Capetian Angevins, who supported the Kotromanić rulers of Bosnia. King Charles Robert once declared that any Hungarian who attacked Bosnia, ruled by his friend Stephen II, would be regarded as a traitor. The only significant impact the Bosnian Crusade had was augmenting the anti-Hungarian sentiment among the Bosnians, a major factor in Bosnian politics that contributed to the Ottoman conquest of Bosnia in 1463 and lasted beyond it.

Who supported the crusade against Bosnia?
Benedict XII
