This book examines the coming of age experiences of young men and women who became active in radical Left circles in 1960s England. Based on a rich collection of oral history interviews, the book follows in depth the stories of approximately twenty individuals to offer a unique perspective of what it meant to be young and on the Left in the post-war landscape. The book will be essential reading for researchers of twentieth-century British social, cultural and political history. However, it will be of interest to a general readership interested in the social protest movements of the long 1960s.
