According to Gregori Maximov (historian of the Russian Revolution) the term anarcho-syndicalism was first used by members of the 'Chicago' or anarchist current of the IWW. This faction of the IWW was libertarian communist.
Anarcho-syndicalism is the fusion of syndicalism and anarchism; especially in relation to the common development of criticism of capitalism, the state, militarism and the causes of bureaucracy. Concerning anarcho-syndicalism today the Statutes of the International Workers Association (IWA-AIT) insist on both the syndicalist demand for workers control of the economy which workers themselves create (revolutionary unionism) and the anarchist demand for a non-coercive stateless society (libertarian communism).
Until the day that members of the IWW start argueing for a Free Confederation of Workers Community and Union Federations, it is not libertarian communist but nothing more than Internationalist General Union, founded in the USA, by Union delegates from the USA, with its headquarters always in the USA.
