The Warsaw Ghetto Uprising of January and April 1943 included the participation of both right- and left-leaning Zionist organizations. Its commander, Mordechai Anielewicz, was a Socialist-Zionist and Zionists of all political spectra played a leading role in the struggle. The uprising's left-leaning survivors eventually made their way to Palestine and founded two Kibbutzim, Lohamei HaGeta'ot and Yad Mordechai.
