Conference For Progressive Political Action

The Conference for Progressive Political Action was officially established by the convention call of the 16 major railway labor unions in the United States, represented by a committee of six: William H. Johnston of the Machinists' Union, Martin F. Ryan of the Railway Carmen, Warren S. Stone of the Locomotive Engineers, E.J. Manion or the Railroad Telegraphers, Timothy Healy of the Stationary Firemen, and L.E. Sheppard of the Railway Conductors. The idea of joining the "forces of every progressive, liberal, and radical organization of the workers must be mobilized to repel these assaults and to advance the industrial and political power of the working class" seems to have originated with the National Executive Committee of the Socialist Party, which issued an appeal to unions and progressive political organizations for such a group in September 1921.

The CPPA was originally intended to be an umbrella organization uniting various elements of the Farmer-Labor political movement around a common program for joint independent political action. In practice, however, invitations to the group's founding conference were issued to members of a wide variety of "progressive" organizations, including those who did not seek a new political organization. As a result, the body was quite heterogeneous and unable to agree on a program or even a declaration of principles at its initial gathering.
