Syndicalism is a labor movement within society that, through industrial unionism, seeks to unionize workers according to industry and advance their demands through strikes and other forms of direct action, with the eventual goal of gaining control over the means of production and the economy at large through social ownership.
Syndicalist unions first emerged in Spain and North America in the 1870s, before rising to prominence in France and later emerging on other continents. Syndicalist movements were most predominant amongst the socialist movement during the interwar period that preceded the outbreak of World War II. Major syndicalist organizations included the General Confederation of Labor (CGT) in France, the Confederacion Nacional del Trabajo (CNT) in Spain, the Italian Syndicalist Union (USI), the Free Workers' Union of Germany (FAUD), and the Argentine Regional Workers' Federation (FORA). Although they did not regard themselves as syndicalists, the Industrial Workers of the World (IWW) (nicknamed "Wobblies") in the United States, the Irish Transport and General Workers' Union (ITGWU), and the Canadian One Big Union (OBU) are considered by most historians to belong to this movement.
