Bevanism was a movement on the left wing of the Labour Party in the late 1950s led by Aneurin Bevan which also included Richard Crossman, Michael Foot and Barbara Castle. Bevanism was opposed by the Gaitskellites, moderate social democrats within the party. The Gaitskellites typically won most of the battles inside Parliament, but Bevanism was stronger among local Labour activists. The Bevanites split over the issue of nuclear weapons, and the movement faded away after Bevan died in 1960.
