The independent countries that once comprised Yugoslavia are Serbia, Montenegro, Kosovo, Bosnia and Herzegovina, Slovenia, Macedonia and Croatia. Yugoslavia, which means "Land of the South Slavs," first formed in 1929.
According to the Encyclopedia Britannica, the country began to split into its constituent parts on June 25, 1991, when Croatia and Slovenia seceded from the union. Five months later, on Dec. 19, 1992, Macedonia also seceded. Bosnian Muslims and Croats in Bosnia and Herzegovina also voted to leave Yugoslavia in February and March of 1992, but the Bosnian Serbs boycotted the vote. To hold onto its territory, the central government unleashed violence on the rebellious provinces. The violence killed many people, but it was not enough to restore the union. Serbia and Montenegro stayed together, creating a new Yugoslavia, but after the war of independence in Kosovo in 1998 and pressure from Montenegrins for independence, the name Yugoslavia was formally retired in 2003.
