Hague Congress

The Hague Congress, held from 2 to 7 September 1872, in the eponymous city, was a congress of the International Workingmen's Association (IWA), more commonly known as the First International. It is one of the fundamental events in the history of the workers' movement, marking the split between the Marxists and the anti-authoritarians/anarchists, two political movements that separated during this congress.
