Young Judaea is the oldest Zionist youth organization in the United States, established as a national organization in 1909 by the Federation of American Zionists. It was supported by Hadassah, including direct financial sponsorship from 1967-2011. The major aims of Young Judaea throughout its history have been to advance the cause of Zionism, to further the mental, moral, and physical development of Jewish youth, and to promote Jewish culture and ideals in accordance with Jewish traditions. Young Judaea has remained non-partisan and non-denominational, embracing and recruiting Jewish youth from all backgrounds.
