Yugoslav irredentism

Yugoslav irredentism was a political idea advocating merging of South Slav-populated territories within Yugoslavia with several adjacent territories, including Bulgaria, Western Thrace and Greek Macedonia.

[1] The government of the communist-ruled Yugoslavia under Josip Broz Tito also sought to create an integral Yugoslavia that would incorporate within its borders: Greek Macedonia, Albania, Pirin Macedonia, at least some of Austrian Carinthia, and for a time the entire Italian region of Friuli-Venezia Giulia.

[6] The Zveno movement participated in the Bulgarian coup d'état of 1934, the coup supporters declared their intention to immediately form an alliance with France and to seek the unification of Bulgaria into an Integral Yugoslavia.

[7] Once World War II began, in 1940 General Milan Nedić proposed that Yugoslavia join the Axis Powers and attack Greece to seize Salonika.

Neither the Soviet Union nor the Western Allies supported Yugoslav claims against Austria and Italy.
