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.

The Youth Aliyah Records in the Hadassah Archives document Hadassah's work with multiple international organizations to rescue Jewish children from continental Europe to Palestine from 1933-1945. The collection also documents Hadassah's involvement with Youth Aliyah since 1946 in providing residential, educational, vocational, rehabilitative and therapeutic care for displaced and at-risk youth from around the world.

The material in this record group was culled from Hadassah's Central Files in Israel in the early 1980s to document Hadassah's role in Zionist history. Originally formed from a Zionist women's study group, the first Hadassah chapter in New York had a strong relationship with the Zionist Organization of America (ZOA; then known as the Federation of American Zionists). The material in this record group documents Hadassah's relationship to the ZOA and to other Zionist organizations in the United States, Europe, and Palestine/Israel, particularly in the years leading up to Israeli statehood in 1948. Other subjects addressed in this record group include the founding of Hadassah; World War II, particularly relating to Jewish emigration and refugees; the founding of the United Nations and the debate over recognition of a Jewish state; the partition of Palestine; and Arab-Jewish relations. Included are articles, clippings, convention resolutions, correspondence, diary extracts, memorandums, minutes, press releases, printed ephemera, publications, reports, and speeches.
