The Republic of Serbia (Serbian: Република Србија or Republika Srbija, listen ), is a landlocked country in Central and Southeastern Europe, covering the southern part of the Pannonian Plain and the central part of the Balkan Peninsula. It is bordered by Hungary on the north; Romania and Bulgaria on the east; Albania and Macedonia on the south; and Montenegro, Croatia and Bosnia and Herzegovina on the west. The capital is Belgrade.
Once a powerful medieval Kingdom and an Empire (which at times ruled most of the Balkans), the modern state of Serbia emerged in 1817 following the Second Serbian Uprising. Later, it expanded its territory further south to include Kosovo and Metohija and the regions of Raška and Macedonia (in 1912). Finally, Vojvodina (formerly an autonomous Habsburg crownland named Voivodship of Serbia and Tamiš Banat) proclaimed itself the autonomous region Banat, Bačka and Baranja, and united with Serbia in November 25, 1918, preceded by the Syrmia region a day before. The current borders of the country were established following the end of World War II, when Serbia became a federal unit within the Socialist Federal Republic of Yugoslavia. Serbia became an independent state again in 2006, after Montenegro left the union which was formed after the dissolution of Yugoslavia in 1990s.
