Abstract: E. L. Doctorow's Ragtime juxtaposes historical and fictional figures in one text. By rewriting the history of the early 20 years of 20th century to construct the social space, the novel presents USA's historical space reproduction as a nation in the macro scale, and discloses in the micro scale the authority's political violence against Coalhouse Walker, who dares to cater for racial equality and justice and against those lower groups who struggle for class benefits in order to maintain the existing social space order. The novel explores the problems of national, racial and class identities, with which it alludes to the society Doctorow lives in.
