The Yugoslavian Federation
In 1918, Serbia, which included much of Macedonia, joined in union with Croatia, Slovenia, and Montenegro to form the Kingdom of Serbs, Croats, and Slovenes, which was renamed Yugoslavia in 1929. Bulgaria joined the Axis powers in World War II and occupied parts of Yugoslavia, including Macedonia, in 1941. During the occupation of their country, Macedonian resistance fighters fought a guerrilla war against the invading troops. The Yugoslavian federation was reestablished after the defeat of Germany in 1945, and in 1946, the government removed the Vardar territory of Macedonia from Serbian control and made it an autonomous Yugoslavian republic. Later, when President Tito recognized the Macedonian people as a separate nation, Macedonia's distinct culture and language were able to flourish, no longer suppressed by foreign rule.
