(Hebrew for “the young guard”) A Jewish youth movement founded in 1913 and based on the principles of Zionism and socialism. Today, the movement operates in nineteen different countries and focuses on youth-led experiential Jewish education as a way for Jews to explore their Jewish identity and “to introduce youth to progressive values of equality, peace and social justice.” See the movement’s United States-based website at http://www.campshomria.com.  http://www.justvision.org/glossary/hashomer-hatzair
