The Unfinished Revolution compares the post-Second World War histories of the American and British gay and lesbian movements with an eye toward understanding how distinct political institutional environments affect the development, strategies, goals, and outcomes of a social movement. The two case study chapters function as brief historical sketches that provide an introduction to British and American gay and lesbian history. An appendix provides a useful evaluative summary of common social movement theories. The book will be of value to academics and students of sociology, political science, and history.
