The Ustase rejected liberalism, and was convinced that Ustase objectives could be attained only through the use of violence and terror (Palmer, 1970, p. 193). In the 1930s, the Croatian Ustase were encouraged and supported by the fascists in Italy (Palmer, 1970, p. 209).The creation of the Yugoslav federation was an anathema to Croatian nationalists and fascists. In the aftermath of the Russian Revolution, Marxist agitation was rife throughout many parts of the world. It was, however, strongest in Europe, especially so in the Baltic states of the northeast, and the Balkan states of the southeast (Hyams, 1973, p. 14).
