This book traces W.E.B. Du Bois's fictionalization of history in his five major works of fiction and in his debut short story The Souls of Black Folk through a thematic framework of cosmopolitanism. In texts like The Negro and Black Folk: Then and Now, Du Bois argues that the human race originated from a single source, a claim authenticated by anthropologists and the Human Genome Project. This book breaks new ground by demonstrating the fashion in which the variants of cosmopolitanism become a profound theme in Du Bois's contribution to fiction. In general, cosmopolitanism claims that people belong to a single community informed by common moral values, function through a shared economic nomenclature, and are part of political systems grounded in mutual respect. This book addresses Du Bois's works as important additions to the academy and makes a significant contribution to literature by first demonstrating the way in which fiction could be utilized in discussing historical accounts in order to reach a global audience. ';The Coming of John', The Quest of the Silver Fleece, Dark Princess: A Romance, and The Black Flame, an important trilogy published sequentially as The Ordeal of Mansart, Mansart Builds a School, and Worlds of Color are grounded in historical occurrences and administer as social histories providing commentary on Reconstruction, Jim Crow segregation, African American leadership, school desegregation, the Pan-African movement, imperialism, and colonialism in Africa, Asia, and the Caribbean.
