Syndicalism is a radical current in the labor movement and was most active in the early 20th century. According to the Marxist historian Eric Hobsbawm, it predominated the revolutionary left in the decade preceding World War I as Marxism was mostly reformist at that time.[1] Major syndicalist organizations included the General Confederation of Labor in France, the National Confederation of Labor in Spain, the Italian Syndicalist Union, the Free Workers' Union of Germany, and the Argentine Regional Workers' Federation. The Industrial Workers of the World, the Irish Transport and General Workers' Union and the Canadian One Big Union, though they did not regard themselves as syndicalists, are considered by most historians to belong to this current. A number of syndicalist organizations were and still are to this day linked in the International Workers' Association.
