Fall of the Serbian DespotateSerbia
Stjepan Tomašević lost two countries to the Ottoman Empire: Serbia in 1459 and Bosnia in 1463. His appointment as new despot was highly unpopular but pushed hard by his father, King Stjepan Tomaš of Bosnia. By this time Serbia was reduced to only a strip of land along the Danube. Sultan Mehmed II decided to conquer Serbia completely and arrived at Smederevo; the new ruler did not even try to defend the city. After negotiations, Bosnians were allowed to leave the city and Serbia was officially conquered by Turks on June 20, 1459.
The Hungarian rulers renewed the legacy of Despots to the House of Branković in exile, later to the noble family of Berislavići Grabarski, who continued to govern most of Syrmia until the Ottoman conquest but territory has been in theory still under administration of the medieval Kingdom of Hungary.
