This book's four main aims are to examine: firstly, why movements happened in the socio-historical context of sixties' radicalism, secondly, its distinctive legacy of crucial, cultural, societal and political interconnections, thirdly, continuing links between seminal ideas and movements and socio-political activism today, fourthly little-discussed national instances and divergent impacts of sixties radicalism, in relation to contemporary 'global' social movements. A conclusion traces all these dimensions from current social movements back to sixties radicalism's pioneering upheavals.
