Editing Communist Party USA (section)

===Formation===
In 1919, the [[Communist International (1919–1943)|Comintern]] urged the formation of a Statesian communist party composed of left elements of [[Socialism|socialist]] groups that supported the [[dictatorship of the proletariat]]. On July 28, many members of the Socialist Party of America, including [[C. E. Ruthenberg]], [[Louis Fraina]], and [[Bertram D. Wolfe]], decided to split and form a new party.<ref>{{Citation|author=Jacob A.

After being expelled from the Socialist Party of America's convention, the Michigan group of the Socialist Party formed the Communist Party of America on September 1, 1919. The Communist Party soon had a membership of 58,000. Another smaller party was formed from this split, the [[Communist Labor Party of America|Communist Labor Party]]. The CPA decided not to cooperate with non-revolutionary parties.<ref name=":0">{{Citation|author=[[William Z.
