Throughout their imprisonment in the ghettos, Jews had found ways to defy and resist Nazi conquerors: they organized mutual aid societies, they continued to practice their religion and educate their children, and they made heroic efforts to document their lives (see reading, Voices from the Warsaw Ghetto in Chapter 8). In more than 100 ghettos, Jews formed underground movements with the goal of escaping the ghetto, joining partisan (armed resistance) groups, or organizing a revolt. Prisoners in several camps, including Auschwitz, Treblinka, and Sobibór, mounted revolts. In Vilna, Bialystock, and several other ghettos, Jews resisted deportations with force. The largest armed resistance by Jews against the Nazis occurred in the Warsaw ghetto.
