This Element's contribution explores the historiography of madness in the Modern era, including landmark publications in the overlapping fields of the history of psychiatry and the history of lunatic asylums. As this examination of almost 200 academic works will demonstrate, the field is vast and highly contested, with researchers sometimes disagreeing about the basic terms of analysis. Nevertheless, from Foucault to Fanon, from Goffman to Gilman, these debates about social and medical responses to madness have inspired some of the most influential academic scholarship of the twentieth century.
