After the Hague Congress (1872), which saw the expulsion of the anarchists Mikhail Bakunin and James Guillaume, it was decided to hold a Congress of the anti-authoritarian Sections and Federations of the International in St. Imier, Switzerland. The Congress was attended by delegates of the International federations in Italy, Spain, Belgium, the United States, France and French-speaking Switzerland. It should be remembered that many sections of the International around this time had membership figures running into the thousands and tens of thousands.
