Yugoslav Partisans

The Yugoslav Partisans, officially the National Liberation Army and Partisan Detachments of Yugoslavia (often shortened as the National Liberation Army) was the communist-led anti-fascist resistance to the Axis powers (chiefly Nazi Germany) in occupied Yugoslavia during World War II. Led by Josip Broz Tito, the Partisans were Europe's most effective anti-Axis resistance movement during World War II.

Primarily a guerrilla force at its inception, the Partisans developed into a large fighting force engaging in conventional warfare later in the war, numbering around 650,000 in late 1944 and organized in four field armies and 52 divisions. The main stated objectives of the Partisans were the liberation of Yugoslav lands from occupying forces and the establishment of a communist-ruled Yugoslav state.
