The Banski Grabovac massacre was the mass killing of 1,100-1,200 Serb civilians by the Croatian fascist Ustaše movement on 24-25 July 1941, during World War II.
After the Axis invasion of Yugoslavia, Adolf Hitler set up the Independent State of Croatia (NDH), a puppet state ruled by the fascist Croatian Ustaše regime led by Ante Pavelić.
