French Workers' Party
Guesde had been in close association with Paul Lafargue, and through him with Karl Marx, whose daughter Lafargue had married. It was in conjunction with Marx and Lafargue that he drew up the programme accepted by the National Congress of the French Workers' Party at Le Havre in 1880, which laid stress on the formation of an international labour party working by revolutionary methods. The following year, at the Reims Congress, the orthodox Marxist programme of Guesde was opposed by the ""possibilists", who rejected the intransigent attitude of Guesde for the reformist policy of Paul Brousse and Benoît Malon.
