1941–1945: The partisan war in Yugoslavia
July 1941 – May 1945 · 2 battles
After the partition of Yugoslavia in April 1941 a partisan war, which was also a civil war, broke out on its territory. Josip Broz Tito’s communist Partisans and Dragoljub Mihailović’s royalist Chetniks fought, first together and then against each other, against the German, Italian, Hungarian and Bulgarian occupiers and against the Ustaša Independent State of Croatia. Germany and its allies mounted a series of great offensives against the Partisans – on the Neretva and the Sutjeska in 1943 Tito barely escaped destruction – and the civilian population paid for every act of resistance with mass reprisals. From 1943 the Western Allies backed Tito, and after Italy’s surrender his army grew to hundreds of thousands of men; the war ended in May 1945 with the liberation of the country and the communists’ seizure of power.
