The United States of Mestizo is a powerful manifesto attesting to the fundamental changes the nation has undergone in the last half-century. Writer Ilan Stavans meditates on how the cross-fertilizing process that defined the Americas during the colonial period—the racial melding of Europeans and indigenous peoples—foretells the miscegenation that is the most salient profile of America today. If, as W.E.B. DuBois once argued, the twentieth century was defined by a color fracture at its core, Stavans believes the twenty-first will be shaped by a multi-color line that will make us all a sum of parts.
