The horror novel appears in the late twentieth century as a significant genre of popular fiction. Growing out of older traditions of the European Gothic and weird fiction, and their trajectory through American literature, the horror novel has produced some of the most famous names in writing, such as Shirley Jackson and Stephen King. Debates about the literary merits of horror have been frequent, but the genre undoubtedly holds an important place in fiction and in American culture more widely. The politics of the horror novel, then, are crucial. This chapter traces the history of critical commentary on the political position of horror, asking if it upholds or questions the status quo. It also moves beyond this model to examine modern transformations of the genre and self-conscious literary responses to the legacy of racism and misogyny that has been a subject of critique. Covering the horror novel’s response to varied social changes, including immigration, the sexual revolution, and the Civil Rights Movement, this chapter argues that it is capable of both reflecting on and exploiting social fears, and that its politics are as varied as its form, which has far more variety than narrow genre definitions might suggest.
