Jugoslavija, 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 Jugoslavija 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 creation of several new nations. Today, the former territories of Jugoslavija are independent countries, each with its own unique culture and history.
