Stephen Tomašević of Bosnia

Stephen Tomašević of Bosnia, born in the year one thousand four hundred thirty-eight, was the last sovereign of the Bosnian Kotromanić dynasty. His reign as Despot of Serbia was brief, lasting only two months in one thousand four hundred fifty-nine, before he became King of Bosnia from one thousand four hundred sixty-one until one thousand four hundred sixty-three.

Stephen's father, King Thomas, had grand ambitions for his son, initially seeking to expand into Croatia through a strategic marriage. However, the plan to wed Stephen to a wealthy noblewoman fell through, and negotiations with the Sforzas of Milan were abandoned in favor of a more prestigious alliance with Maria of Serbia. This marriage, celebrated in April one thousand four hundred fifty-nine, positioned Stephen as the ruler of the remnants of Serbia, aiming to unite Bosnia and the Serbian Despotate against the advancing Ottoman Empire.

Despite his noble intentions, Stephen's Catholic faith rendered him unpopular among the Orthodox population of Serbia. After a mere two months of rule, he surrendered Serbia to the Ottoman forces and retreated to his father's court, incurring the disdain of Hungarian King Matthias Corvinus and other Christian monarchs across Europe.

Upon his father's death on July tenth, one thousand four hundred sixty-one, Stephen ascended to the throne and became the first Bosnian king to receive a crown from the Holy See. His reign was marked by the looming threat of the Ottomans, and while he enjoyed the support of his noblemen, the common people were less enthusiastic. Stephen maintained correspondence with Pope Pius II, who forgave him for the loss of Serbia and collaborated with him to preserve Bosnia for Christendom.

Confident in the support of Matthias, Stephen refused to pay the customary tribute to the Ottoman Sultan Mehmed the Conqueror, provoking an invasion. In May one thousand four hundred sixty-three, Mehmed marched into Bosnia, facing little resistance, and captured Stephen, who was subsequently beheaded. This execution signified the fall of the Kingdom of Bosnia to the Ottoman Empire.
