Gush Etzion (Hebrew: גּוּשׁ עֶצְיוֹן‎, lit. Etzion Bloc) refers to a group of Jewish villages established from the 1920s south of Jerusalem on the northern part of Mount Hebron in the southern West Bank, and destroyed during the 1948 Arab–Israeli War: Kfar Etzion, Massu'ot Yitzhak, Ein Tzurim and Revadim. The first three were aligned with the religious orthodox, and Revadim was aligned with Hashomer Hatzair (Young guards). It also refers to the four Israeli settlements re-established following the 1967 Six-Day War, and those settlements that have expanded the area of the Etzion Bloc.
