Following King Aleksandar’s proclamation of a dictatorship in January 1929, the lawyer Ante Pavelic fled the Kingdom of Yugoslavia and established the Ustasha – Croatian Revolutionary Organisation. It soon became notorious for its terrorist acts, and later for establishing a violent fascist regime during the Second World War. The organisation emerged from the activities of the members of the Croatian Party of Rights and its youth section Croatian Home Guard. During the 1930s the Ustasha organisation went through a process of fascistisation, while simultaneously adapting fascist ideology to suit their concrete political and social context and goals. The representatives of the Croatian nation have on several occasions addressed the League of Nations in an attempt to warn about the situation created in Croatia during the ten years of coexistence with Serbia.
