Step-by-step explanation:
Yugoslavia: A Historic Overview
The ethnic groups Albanians, Bosnians, Croats, and Serbs once made up the majority of the population in the country of Yugoslavia. After the death of their leader, Marshall Tito, in 1980, the country experienced increasing religious and ethnic tensions, eventually leading to its violent breakup in the early 1990s. The dissolution followed ethnic and religious lines with the Bosniaks inhabiting Bosnia-Herzegovina, Slovenes and Croats occupying Slovenia and Croatia, and Montenegrins, Macedonians, and Serbs located in Montenegro, Macedonia, and Serbia, respectively. The breakup of Yugoslavia created multiple sovereign states from the territories that once were united under a common language and cultural practices, leading to a valuable lesson in political and cultural geography.
Yugoslavia, which existed from 1918 until its dissolution in the 1990s, was nicknamed the 'Land of the South Slavs,' highlighting the shared linguistic bond. Yugoslavia's disintegration was fueled by nationalism and the weakening of Communist power in Europe. The resulting wars, especially in Bosnia, were marked by severe ethnic conflict. Despite being a diplomatic creation, the multi-ethnic composition made the cohesion of Yugoslavia precarious once the unifying factors weakened.
