The International Workingmen's Association (IWA), commonly known as the First International, was an international association of trade unionist and socialist political activists which attempted to coordinate labor activities across national boundaries. The organization is remembered for the active participation of many pioneer leaders of the modern socialist and anarchist movements, including Karl Marx and Mikhail Bakunin. Membership in the IWA was numerically small, its funding inadequate, and its institutional life short — lasting a mere 8 years from its establishment in 1864 until its termination at the Hague Congress of 1872.
