Anti-Fascist Struggle Day is a public holiday in Croatia. It is observed on 22 June and commemorates the formation of the First Sisak Partisan Detachment, a Communist-led guerrilla unit during World War II in Yugoslavia on 22 June 1941, and in general the uprising of the anti-fascist Croatian wing of the Yugoslav Partisans against the forces of Nazi Germany, Fascist Italy and their puppet state―Independent State of Croatia.
