What best describes Yugoslavia before its breakup?

The answer is Yugoslavia was a Socialist state created after German occupation in World War II and a civil war. A federation of six republics, it brought together Serbs, Croats, Bosnian Muslims, Albanians, Slovenes and others under a comparatively relaxed communist regime. Tensions between these groups were successfully suppressed under the leadership of President Tito. After his death, nationalism tore Yugoslavia apart. Tensions between the republics and nations of Yugoslavia intensified from the 1970s to the 1980s. The causes for the collapse of the country have been associated with nationalism, ethnic conflict, economic difficulty, frustration with government bureaucracy, the influence of important figures in the country, and international politics.
