Headquarters of the youth organization Hashomer Hatzair and editorial office of the newspaper Oyf der vakh

Hashomer Hatzair (Heb. the Young Guard) is a left-Zionist youth movement founded in Galicia in 1913 which significantly influenced the kibbutz movement and sent young men and women to Palestine as chaluzim (Heb. pioneers) shortly after World War II. Members of the association participated as partisans and ghetto fighters in the resistance against the Nazi regime. After 1945, Hashomer Hazair smuggled thousands of Jewish children and youths from Eastern Europe to DP camps. From fall 1947 until January 1949, the movement published the Yiddish-language newspaper Oyf der vakh (Yid. on Guard).
