What best describes Yugoslavia before its breakup? Yugoslavia before its breakup in the 1990s was a federal socialist state composed of six republics: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia. It was created after World War II and was initially led by Josip Broz Tito, who pursued a nonaligned foreign policy and successfully maintained unity among the various ethnic and religious groups within the country for several decades. Yugoslavia had a mixed economy with elements of both state-control and private enterprise, and it was an important player in the global socialist movement. However, nationalist and ethnic tensions simmered beneath the surface, and eventually erupted into violence and conflict in the 1990s, leading to the breakup of the country.
