Jewish Military Union
Żydowski Związek Wojskowy (ŻZW, Polish for "Jewish Military Union," ) was an underground resistance organization operating during World War II in the area of the Warsaw Ghetto, which fought during the Warsaw Ghetto Uprising and 1944 Warsaw Uprising. It was formed, primarily of former officers of the Polish Army, in late 1939, soon after the start of the German occupation of Poland.
