New Left, a broad range of left-wing activist movements and intellectual currents that arose in western Europe and North America in the late 1950s and early ’60s. Often regarded as synonymous with the student radicalism of the 1960s, which culminated in the mass protests of 1968 (most notably the events of May 1968 in France), it may also refer more narrowly to particular segments within or alongside those movements.
