This article examines the experience of distinct groups within the Socialist Party of America, considering the period from its founding in 1901 to the eve of World War One. The Socialist Party, befitting its membership in the international socialist movement of that era, was committed to representing the workers of the world in the Marxist struggle to achieve political and economic equality within a cooperative commonwealth. Accordingly, variables of gender, ethnicity and race were subsumed within the Social Question. Ideally, workers in every capacity and of all backgrounds would march together under the Red Flag and create a new egalitarian society. While, indeed, many lawyers, ministers and others of the middle-class belonged to the Socialist Party and often held office within it, thereby derisively being likened by critics to an assemblage of dentists, the party was very much working class in composition, as shown by James R. Green and others.
