The Solidarity Federation, also known by the abbreviation SolFed, is a federation of class struggle anarchists active in Britain. The organisation advocates a strategy of anarcho-syndicalism as a method of abolishing capitalism and the state, and describes itself as a "revolutionary union". In 1994 it adopted its current name, having previously been the Direct Action Movement since 1979, and before that the Syndicalist Workers' Federation since 1950. Along with the Anarchist Federation it is one of the two anarchist federations active in the UK.
