International Workers' Association
From Peter Gelderloos, Anarchy Works:
The anarcho-syndicalist movement originating in Europe has a history of creating international federations to share information and coordinate struggles against capitalism. These federations could be a direct precedent to global structures that facilitate living in peace and preventing warfare. The International Workers Association (IWA, or AIT in Spanish) contains anarcho-syndicalist unions from about 15 countries on 4 continents, and it periodically holds international congresses, each time in a different country. The IWA was formed in 1922, and initially contained millions of members. Although nearly all of its member unions were forced underground or into exile during World War II, it has since regenerated and continues to meet.
The IWA's website is http://www.iwa-ait.org/.
