Parti ouvrier français
The Federation of the Socialist Workers of France was termed "possibilist" because it advocated gradual reforms, whereas the French Workers' Party promoted Marxism. In 1905 these two trends merged to form the French Section Française de l'Internationale Ouvrière (SFIO), led by Jean Jaurès and later Léon Blum. In 1906 it won 56 seats in Parliament. The SFIO adhered to Marxist ideas but became, in practice, a reformist party. By 1914 it had more than 100 members in the Chamber of Deputies.
