Histories of masculinity have generally examined both social ideologies of masculinity and subjective male identities within frameworks that define them against the feminine. Yet historians and sociologists have increasingly argued that men have been and continue to be defined both socially and subjectively as much by their relations to other men as in relation to women. This collection brings together the work of scholars of masculinities working in a variety of fields, including literature, history and art history, to examine some of the forms of ‘otherness’ against which ideas of masculinity have been defined throughout history. The collection reflects the current breadth of scholarship relating to the study of masculine alterity. While the subjects addressed are largely historical, the time span covered is broad and the disciplinary approaches to the subject matter are equally wide-ranging. A huge variety of men, masculine behaviours and definitions of masculinity are considered in an exciting and invigorating collection that showcases both established academics and emerging scholars in the field.
