Yugoslavija, or Yugoslavia, was a country in Southeast Europe that existed from 1918 until its dissolution in the early 1990s. It was formed after World War I, uniting several ethnic groups, including Serbs, Croats, and Slovenes. The country was a socialist federation, consisting of six republics: Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, North Macedonia, and Serbia. The breakup of Yugoslavia was marked by a series of conflicts and wars, leading to the independence of its republics. The process was complex and involved significant political and ethnic tensions, resulting in the formation of several new nations. Today, the legacy of Yugoslavia continues to influence the region's politics and culture.
