intervention against Yugoslavia in April 1941 Albanian Croatian Macedonian separatists Yugoslavia National Assembly of Yugoslavia Stjepan Radić Ante Pavelić Ustaše Italy
Italy justified its intervention against Yugoslavia in April 1941 by appealing to both Italian irredentist claims and the fact of Albanian, Croatian, and Macedonian separatists not wishing to be part of Yugoslavia. Croatian separatism soared after the assassination of Croatian political leaders in the National Assembly of Yugoslavia in 1928 including the death of Stjepan Radić, and Italy endorsed Croatian separatist Ante Pavelić and his fascist Ustaše movement that was based and trained in Italy with the Fascist regime's support prior to intervention against Yugoslavia.
