"Yugoslav" refers to anything related to the former country of Yugoslavia, which existed from 1918 until its dissolution in the early 1990s. The term encompasses the diverse cultures, languages, and ethnic groups that were part of this multi-national state, including Serbs, Croats, Bosniaks, Slovenes, Macedonians, and Montenegrins. Yugoslavia was formed after World War I and was initially a kingdom. It later became a socialist federation under the leadership of Josip Broz Tito. The country experienced significant political and social changes, ultimately leading to conflicts and the breakup into several independent nations during the Yugoslav Wars.
