Yugoslavia (1918–1992)

Socialist Federal Republic of Yugoslavia

Born as a kingdom of South Slavs after WWI and reborn as Tito's socialist federation after WWII, Yugoslavia broke apart in the wars of the early 1990s — seven countries now stand on its territory.

The Yugoslav red passport was one of the Cold War's most powerful travel documents — welcome on both sides of the Iron Curtain, a perk of leading the Non-Aligned Movement.
