This chapter examines and compares the social and political history of the communist youth movement in Britain and the Netherlands between 1969 and 1991. It looks primarily at the histories of the British Young Communist League (YCL) and its Dutch equivalent, the Algemeen Nederlands Jeugdverbond (ANJV; ‘General Dutch Youth League’). It explores these organisations’ roles in the feminist, anti-racist, and gay rights movements in the final two decades of their existence, and details their changing relationship with their respective communist parties as the Cold War came to an end.
