On 6 April 1941, Yugoslavia was invaded by the Axis powers led by Nazi Germany; by 17 April 1941, the country was fully occupied and was soon carved up by the Axis. Yugoslav resistance was soon established in two forms, the Royal Yugoslav Army in the Homeland and the Communist Yugoslav Partisans. The Partisan supreme commander was Josip Broz Tito, and under his command the movement soon began establishing "liberated territories" which attracted the attention of occupying forces. Unlike the various nationalist militias operating in occupied Yugoslavia, the Partisans were a pan-Yugoslav movement promoting the "brotherhood and unity" of Yugoslav nations, and representing the republican, left-wing, and socialist elements of the Yugoslav political spectrum. The coalition of political parties, factions, and prominent individuals behind the movement was the People's Liberation Front ("Jedinstveni narodnooslobodilački front", JNOF), led by the Communist Party of Yugoslavia (KPJ).
