The Arbiter Ring, the Growth and Decline of the Socialist Labor Movement in the Pittsburgh Jewish Community 1904-1947
Like most immigrants to the United States in the early part of this century, Jewish immigrants were in the majority members of the working class. They took jobs in the sweated industries of the cities where they lived, and they formed unions and other labor organizations. Many of these Jewish labor organizations had a socialist political agenda. The foremost socialist Jewish organization was the Workmen's Circle National Organization (Arbeiter Ring in Yiddish).
