 At the end of December 1912 Rauze held a dinner at which the constitution of the feminine section of the SFIO was agreed.Madeleine Pelletier refused her invitation to this event, ostensibly because her stomach was very delicate, but probably because the young and beautiful Marianne Rauze was the type of woman that Pelletier detested.In January 1913 Rauze, Saumoneau, Renaud and others founded the Socialist Women's Group ("Groupe des Femmes Socialistes", GDFS) for women within the SFIO.
