During the Cold War, Ellis Island no longer served as the largest port of entry for immigrants, but as a prison for holding aliens the state wished to deport. The government criminalized those it considered un-assimilable (from left-wing intellectuals and black radicals to racialized migrant laborers) through the denial, annulment, and curtailment of citizenship and its rights. The island, ceasing to represent the iconic ideal of immigrant America, came to symbolize its very limits. Unbecoming Americans sets out to recover the shadow narratives of un-American writers forged out of the racial and political limits of citizenship. In this collection of Afro-Caribbean, Filipino, and African American writers—C.L.R. James, Carlos Bulosan, Claudia Jones, and Richard Wright—Joseph Keith examines how they used their exclusion from the nation, a condition he terms “alienage,” as a standpoint from which to imagine alternative global solidarities and to interrogate the contradictions of the United States as a country, a republic, and an empire at the dawn of the "American Century.” Building on scholarship linking the forms of the novel to those of the nation, the book explores how these writers employed alternative aesthetic forms, including memoir, cultural criticism, and travel narrative, to contest prevailing notions of race, nation, and citizenship. Ultimately they produced a vital counter-discourse of freedom in opposition to the new formations of empire emerging in the years after World War II, forms that continue to shape our world today.
