list the countries that made up the former yugoslavia
Breakup of Yugoslavia After the Allied victory in World War II, Yugoslavia was set up as a federation of six republics, with borders drawn along ethnic and historical lines: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia and Slovenia. In addition, two autonomous provinces were established within Serbia: Vojvodina and Kosovo. Each of the republics had its own branch of the League of Communists of Yugoslavia party and a ruling elite, and any tensions were solved on the federal level. The Yugoslav model of state organization, as well as a "middle way" between planned and liberal economy, had been a relative success, and the country experienced a period of strong economic growth and relative political stability up to the 1980s, under the rule of president-for-life Josip Broz Tito. After his death in 1980, the weakened system of federal government was left unable to cope with rising economic and political challenges.
World War II In September 1944, Soviet troops advanced into Yugoslavia and forced the rapid withdrawal of German Army Groups E and F in Greece, Albania and Yugoslavia to rescue them from being cut off.[256] By this point, the Communist-led Partisans under Marshal Josip Broz Tito, who had led an increasingly successful guerrilla campaign against the occupation since 1941, controlled much of the territory of Yugoslavia and engaged in delaying efforts against German forces further south. In northern Serbia, the Red Army, with limited support from Bulgarian forces, assisted the Partisans in a joint liberation of the capital city of Belgrade on 20 October. A few days later, the Soviets launched a massive assault against German-occupied Hungary that lasted until the fall of Budapest in February 1945.[257] Unlike impressive Soviet victories in the Balkans, bitter Finnish resistance to the Soviet offensive in the Karelian Isthmus denied the Soviets occupation of Finland and led to a Soviet-Finnish armistice on relatively mild conditions,[258][259] although Finland was forced to fight their former allies.
