The Kingdom of Serbs, Croats, and Slovenes was formed in 1918; its name was changed to Yugoslavia in 1929. Various paramilitary bands resisted Nazi Germany's occupation and division of Yugoslavia from 1941 to 1945, but fought each other and ethnic opponents as much as the invaders. The military and political movement headed by Josip "TITO" Broz (Partisans) took full control of Yugoslavia when German and Croatian separatist forces were defeated in 1945. Although Communist, TITO's new government and his successors (he died in 1980) managed to steer their own path between the Warsaw Pact nations and the West for the next four and a half decades. In 1989, Slobodan MILOSEVIC became president of the Republic of Serbia and his ultranationalist calls for Serbian domination led to the violent breakup of Yugoslavia along ethnic lines. In 1991, Croatia, Slovenia, and Macedonia declared independence, followed by Bosnia in 1992. The remaining republics of Serbia and Montenegro declared a new Federal Republic of Yugoslavia (FRY) in April 1992 and under MILOSEVIC's leadership, Serbia led various military campaigns to unite ethnic Serbs in neighboring republics into a "Greater Serbia." These actions led to Yugoslavia being ousted from the UN in 1992, but Serbia continued its - ultimately unsuccessful - campaign until signing the Dayton Peace Accords in 1995. MILOSEVIC kept tight control over Serbia and eventually became president of the FRY in 1997. In 1998, an ethnic Albanian insurgency in the formerly autonomous Serbian province of Kosovo provoked a Serbian counterinsurgency campaign that resulted in massacres and massive expulsions of ethnic Albanians living in Kosovo. The MILOSEVIC government's rejection of a proposed international settlement led to NATO's bombing of Serbia in the spring of 1999, to the withdrawal of Serbian military and police forces from Kosovo in June 1999, and to the stationing of a NATO-led force in Kosovo to provide a safe and secure environment for the region's ethnic communities. FRY elections in late 2000 led to the ouster of MILOSEVIC and the installation of democratic government. MILOSEVIC was arrested in 2001 and sent to be tried in The Hague for crimes against humanity; he died in March 2006 before the completion of his trial. In 2001, the country's suspension from the UN was lifted. In 2003, the FRY became Serbia and Montenegro, a loose federation of the two republics with a federal level parliament. Widespread violence predominantly targeting ethnic Serbs in Kosovo in March 2004 caused the international community to open negotiations on the future status of Kosovo in January 2006. In May 2006, Montenegro invoked its right to secede from the federation and - following a successful referendum - it declared itself an independent nation on 3 June 2006. Two days later, Serbia declared that it was the successor state to the union of Serbia and Montenegro. A new Serbian constitution was approved in October 2006 and adopted the following month. In February 2008, after nearly two years of inconclusive negotiations, the UN-administered province of Kosovo declared itself independent of Serbia - an action Serbia refuses to recognize. At Serbia's request, the UN General Assembly (UNGA) in October 2008 sought an advisory opinion from the International Court of Justice (ICJ) on whether Kosovo's unilateral declaration of independence was in accordance with international law. In a ruling considered unfavorable to Serbia, the ICJ issued an advisory opinion in July 2010 stating that international law did not prohibit declarations of independence. In late 2010, Serbia agreed to an EU-drafted UNGA Resolution acknowledging the ICJ's decision and calling for a new round of talks between Serbia and Kosovo.
