This is an exciting new edition of R.W. Connell's groundbreaking text, which has become a classic work on the nature and construction of masculine identity. In its first edition, Masculinities provided one of the most important voices in feminist scholarship by men. Connell argued that there is no such thing as a single concept of masculinity, but, rather, that many different masculinities exist, each associated with different positions of power. In a world in which gender order continues to extend privilege to men over women, but that also raises difficult issues for men and boys, Connell's account is more pertinent than ever. In the new edition's substantial new introduction and conclusion, Connell discusses the development of masculinity studies in the ten years since the book's initial publication. She explores global gender relations, new theories, and practical uses of masculinity research. Looking to the future, her new concluding chapter addresses the politics of masculinities, and the implications of masculinity research as a way of understanding current world issues. Against the backdrop of an increasingly divided world, one that is presently dominated by neo-conservative politics, Connell's account highlights a series of compelling questions about the future of human society. This second edition of Connell's classic book will be essential reading for students taking courses on masculinities and gender studies and will be of interest to students and scholars across the humanities and social sciences.
