塞尔维亚王国
Although, Serbo-Croatian speaking South Slavs settled in Serbian Podunavlje in the 6th century, Serbian state did not reached the river Danube before 13th century. Kingdom of Syrmia ruled by Serb king Stefan Dragutin (1284–1316) included southern Podunavlje and had its capitals in Debrc and Belgrade. The southern Podunavlje was subsequently included into other medieval Serbian states, notably the Serbian Empire, the Moravian Serbia and the Serbian Despotate. The Serbian Despotate had its capitals in Podunavlje, notably in Belgrade and Smederevo. After the Ottoman conquest of Serbian Despotate in 1459, Serbian statehood was temporarily restored in northern Podunavlje (in present-day Vojvodina) between 1526 and 1530, during the reigns of emperor Jovan Nenad and duke Radoslav Čelnik.
