World War II: Yugoslav Partisans convene the first meeting of the Anti-Fascist Council for the National Liberation of Yugoslavia at Bihać in northwestern Bosnia.

The Yugoslav Partisans, officially the National Liberation Army and Partisan Detachments of Yugoslavia was the communist-led anti-fascist resistance to the Axis powers 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.
