International Workers Congresses of Paris, 1889
Two congresses were held in Paris, beginning on July 14, 1889. They had been called for by the London International Trades Union Congress, meeting in London in November 1888, and the French Syndicalist Congress, meeting at the same time. Internecine conflicts within the French socialist movement, however, prompted the "possibilist" faction to hold its own congress at the same time. The larger assembly, the International Socialist Workers Congress of Paris, dubbed the "Marxist" congress resolved to arrange a second meeting at Zurich, and the Possibility one at Brussels. However the Marxist organizing committee decided to relent and the next congress met in Brussels in 1891.
