The Industrial Workers of the World (IWW), members of which are commonly termed "Wobblies", is an international labor union that was founded in 1905 in Chicago, Illinois, in the United States. The union combines general unionism with industrial unionism, as it is a general union, subdivided between the various industries which employ its members. The philosophy and tactics of the IWW are described as "revolutionary industrial unionism", with ties to both socialist, syndicalist and anarchist labor movements.
