This chapter names and surveys a racially attuned subgenre of US historical fiction, the historical novel of whiteness. It studies a variety of authors from the nineteenth, twentieth, and twenty-first centuries, all of whom used the historical novel form to question the coherence and ontological status of “whiteness” as a racial concept. The essay focuses on three historically situated companies of works that epitomize the subgenre: novels of European–Native American contact from the 1820s, “color-line” novels from the Jim Crow era, and African American historical fiction from the post-1945 period. In all the novels under review, whiteness is shown to be a mutable, contingent, surprisingly unstable phenomenon, even as it is also shown to have been a powerful, all but hegemonic force throughout US history.
