The anarchist movement which spread across Spain in the late 18th and early 20th centuries was based on the ideas of Bakunin and propagated by Giuseppi Fanelli. It urged oppressed workers to unite and organize against their oppressors, namely the State, the latifundista landowners, and the Church. It quickly took a hold amongst the long-exploited agricultural workers in Andalusia, who joined the CNT union or the more radical FAI and had some limited success in improving wages and working conditions.
