The Movimiento Ibérico de Liberación (MIL, sometimes known as 1000) was a Catalan left-wing political and urban guerrilla organisation[1][2][3] between 1971 and 1973, based mainly in Barcelona, Spain, and in Toulouse, France.
It became famous after its dissolving because of the execution by the Francoist State of one of its members, Salvador Puig Antich, in March 1974, and of the shooting of Oriol Solé Sugranyes during his escape in 1976.
The MIL advocated violent direct action against Francoist Spain and capitalism, carrying out bank robberies ("expropriations"), allegedly to support the working class' struggle.
It was formed by members from various origins, Marxists, anarchists, etc., and supported council communism, situationism and other ultra-leftist theories which were opposed by other left-wing organized parties.
The MIL published various books and leaflets prohibited in Spain, such as texts by Camillo Berneri, Antonie Pannekoek and the Situationist International.
