Croatian Partisans
The Croatian Partisans, officially the National Liberation Movement in Croatia (Croatian: Narodnooslobodilački pokret u Hrvatskoj; NOP), were part of the anti-fascist National Liberational Movement in the Axis-occupied Yugoslavia which was "perhaps Europe's most effective anti-Nazi resistance movement". It was led by Yugoslav revolutionary communists during the World War II. NOP was under the leadership of the League of Communists of Yugoslavia (KPJ) and supported by many others, with Croatian Peasant Party members contributing to it significantly.
