Upon his father's death in 1461, Stephen Tomašević succeeded to the throne of Bosnia, a kingdom whose existence was being increasingly threatened by the Ottomans. In same year, Stephen Tomašević made an alliance with the Hungarians and asked Pope Pius II for help in the face of an impending Ottoman invasion. In 1463, after a dispute over the tribute paid annually by the Bosnian Kingdom to the Ottomans, he sent for help from the Venetians. However, no help ever arrived to Bosnia from Christendom; King Matthias Corvinus of Hungary, Skenderbeg of Albania and the Ragusans all failed to carry out their promises, while the Venetians flatly refused the king's pleas. In 1463, Sultan Mehmed the Conqueror led an army into the country. The royal city of Bobovac soon fell, leaving Stephen Tomašević to retreat to Jajce and later to Ključ. Mehmed invaded Bosnia and conquered it very quickly, executing the last Bosnian king Stephen Tomašević and his uncle Radivoj. Bosnia officially fell in 1463 and became the westernmost province of the Ottoman Empire.
