The Ustaša - Croatian Revolutionary Movement (Croatian: Ustaša - Hrvatski revolucionarni pokret, before 1933 it was called Ustaša - Croatian Revolutionary Organization; Croatian: Ustaša - Hrvatska revolucionarna organizacija; members known collectively as Ustaše, but sometimes anglicised as Ustashe, Ustashas or Ustashi) was a Croatian fascist movement. The ideology of the movement was a blend of Nazism and Croatian nationalism. The Ustaše supported the creation of a Greater Croatia that would span to the River Drina and to the border of Belgrade. The movement emphasized the need for a racially "pure" Croatia and promoted persecution and genocide against Serbs, Jews and Romani people. Fiercely nationalistic, the Ustaše were also fanatically Catholic. In the Yugoslav political context, they identified Catholicism with Croatian nationalism. Following Croatian nationalism, they declared the Catholic and Muslim faiths as religions of the Croatian people. The Ustaše also saw the Islam of Bosniaks as a religion which "keeps true the blood of Croats."
