On 4 July, in the wake of the Axis invasion of the Soviet Union, the Communist Party of Yugoslavia (Serbo-Croatian: Komunistička partija Jugoslavije, KPJ) decided to launch a general uprising against the occupying forces across Yugoslavia, in solidarity with the Soviets, and a full-scale rebellion broke out in Bosnia on 27 July.[8] This included local uprisings in the Bosanska Krajina, which spread across the NDH, but the KPJ organisation was initially swept along in the popular uprisings rather than leading the rebellion.[9]
