Confederación Nacional del Trabajo

The Confederación Nacional del Trabajo (CNT; lit. 'National Confederation of Labor') is a Spanish anarcho-syndicalist trade union confederation. Founded in 1910 in Barcelona from groups brought together by the trade union Solidaridad Obrera, it significantly expanded the role of anarchism in Spain, which can be traced to the creation of the Spanish chapter of the IWA in 1870 and its successor organization, the Federation of Workers of the Spanish Region.
