Tours Congress

• The larger one gathered those who had accepted the Third International's 21 Conditions behind Fernand Loriot, Boris Souvarine, Ludovic Frossard, and Marcel Cachin. They did not, however, accept all of Lenin's conditions, and no vote on the matter took place. This left-wing faction, formed by the younger leaders of the party and most of the SFIO's members, obtained three-quarters of the votes and split away to form the French Section of the Communist International. They took with them the party paper L'Humanité, founded by Jean Jaurès in 1904. L'Humanité remained tied to the party until the 1990s.
• The second faction was led by a minority who accepted the adhesion to the Third International, but only under specific conditions. They finally allied themselves to the third faction.
• The third faction led by Léon Blum and most elected socialists, who completely refused Lenin's conditions and preferred staying inside of the Second International. Blum, who would become Prime Minister during the 1936–1938 Popular Front, famously declared: "Someone has to stay and keep the old house."
