from Wikipedia Serbia:
Serbia (Serbian: Србија, Srbija), officially the Republic of Serbia (Serbian: Република Србија, Republika Srbija, listen (help·info)), 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. Serbia is bordered by Hungary to the north; Romania and Bulgaria to the east; the Republic of Macedonia and Albania to the south; and Croatia, Bosnia and Herzegovina and Montenegro to the west. The capital is Belgrade.
For centuries, shaped at cultural boundaries between East and West, a powerful medieval kingdom – later renamed the Serbian Empire – occupied much of the Balkans. The Serbian Empire collapsed after wars with the Ottomans and Habsburgs beginning in the 16th century which captured its territories. The modern Serbia emerged in 1817 following the Serbian revolution. Within a century it reacquired Kosovo, Raška and Vardar Macedonia from the Ottoman Empire. Likewise, in 1918 the former autonomous Habsburg crownland of Vojvodina proclaimed its secession from Austria-Hungary to unite with Serbia, preceded by the Syrmia region.
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 that formed after the dissolution of Yugoslavia in 1990s.
In February 2008, the parliament of Kosovo unilaterally declared independence from Serbia. Serbia's government, as well as the UN Security Council, have not recognized Kosovo's independence. The response from the international community has been mixed. Serbia is a member of the United Nations, the Organization for Security and Co-operation in Europe, and the Council of Europe, and is an associate member of the European Union.
