Croatian nationalists Alexander I of Yugoslavia Internal Macedonian Revolutionary Organization Yugoslav Partisan Yugoslavia Macedonia Kingdom of Yugoslavia Croatian Ustaše
The platform of the Ustaše movement proclaimed that Croatians had been oppressed by the Serb-dominated Kingdom of Yugoslavia, and that Croatians deserved to have an independent nation after years of domination by foreign empires. The Ustaše perceived Serbs to be racially inferior to Croats and saw them as infiltrators who were occupying Croatian lands. They saw the extermination and expulsion or deportation of Serbs as necessary to racially purify Croatia. While part of Yugoslavia, many Croatian nationalists violently opposed the Serb-dominated Yugoslav monarchy, and assassinated Alexander I of Yugoslavia, together with the Internal Macedonian Revolutionary Organization. Ustashe forces fought against communist Yugoslav Partisan guerrilla throughout the war.
