During World War II, the Ustaša, a movement of radical Croatian nationalists and fascists, which ruled the Axis puppet state Independent State of Croatia (1941-5), created after the Invasion of Yugoslavia, and conducted genocidal campaigns against Serbs, Jews and Romani people. The salute ""Za Dom – spremni!"" was immediately instituted as a new, revolutionary salute to be used in official correspondence and everyday life. On 10 April 1941, Slavko Kvaternik, designated commander-in-chief of the State's Armed Forces, and deputy of state leader ("Poglavnik") Ante Pavelić proclaimed the establishment of the state on Radio Zagreb, and ended the statement with "Bog i Hrvati! Za dom spremni!" (English, "God and the Croats! For the homeland prepared!")
