Committee for the Preservation of the Socialist Party

The Committee for the Preservation of the Socialist Party was a short-lived organized factional grouping in the Socialist Party of America established in 1934 by its New York–based "Old Guard" faction. The Committee was initially organized to fight for the defeat of the Declaration of Principles adopted by the 1934 National Convention in the referendum for its ratification taken by mail vote of party members. After the Declaration of Principles was passed, the Committee served as the organizational core of the Social Democratic Federation of America, a rival social democratic organization to the Socialist Party established in 1936.
