Dror was founded in Poland in 1915 out of a wing of the Tze'irei Tziyon (Zion Youth) study circle. It is a Jewish Socialist-Zionist cultural youth movement to educate and bring Jewish culture to its members. Members of Dror participated in the Warsaw Ghetto uprising. Mordechaj Tenenbaum and other Dror members organised two underground factions in the Bialystok Ghetto.
