Warsaw Uprising. For other uses, see Warsaw Uprising (disambiguation). The Warsaw Uprising (Polish: Powstanie Warszawskie; German: Warschauer Aufstand) was a major World War II operation by the Polish resistance Home Army (Polish: Armia Krajowa) to liberate Warsaw from German occupation.
The most notable exception was the Warsaw Ghetto Uprising of 1943, when thousands of poorly-armed Jewish fighters held the Waffen-SS at bay for four weeks. An estimated 20,000 to 30,000 Jewish partisans actively fought against the Nazis and their collaborators in Eastern Europe.
