Formed in 1900 by Yiddish-speaking Jewish immigrants from Eastern Europe, The Workmen's Circle at first acted as a mutual aid society, helping its members to adapt to their new life in America. It provided life insurance, unemployment relief, healthcare, social interaction, burial assistance and general education through its branches throughout the US as well as through its national office. Soon, the organization was joined by more politically focused socialist Bundists who advocated the anti-assimilationist idea of Yiddish cultural autonomy, led by education in Yiddish and socialist ideals. The Circle formed the Folksbiene Yiddish theatre troupe and promoted Jewish arts and music, Yiddish school programs for children and Yiddish summer camps. It became influential in the American labor movement and grew to serve more than 84,000 members through hundreds of branches around North America. It also became involved with the Yiddish newspaper "The Forward" and operated old-age homes, medical clinics and other services.
