When working with the latter group it is also known as CNT-AIT. Historically, the CNT has also been affiliated with the Federación Anarquista Ibérica (Iberian Anarchist Federation – FAI). In this capacity it was referred to as the CNT-FAI. Throughout its history, it has played a major role in the Spanish labor movement. 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 Federación de Trabajadores de la Región Española, the successor organization to the Spanish chapter of the IWA. Despite several decades when the organization was illegal in Spain, today the CNT continues to participate in the Spanish worker's movement, focusing its efforts on the principles of workers' self-management, federalism, and mutual aid."
