Yugoslavia is a country in Europe.
During Second World War Yugoslavia was liberated by the Soviet Union. Later in 1955 it expanded to include Bulgaria.
During the Cold War, Yugoslavia was originally allied to the USSR early on, until 1961 when it shifted to neutrality.
Yugoslavia managed to hold itself together, even after the fall of the USSR. Yugoslavia peacefully transitioned into a democracy in 1990. They soon joined the European Union in 1992, and became part of the Eurozone in 2004.
