Parti ouvrier français
Also featured in the review, Georges Sorel was a senior syndicalist with Marxist leanings, not affiliated with either Guesde's French Workers' Party (POF) or Millerand's smaller socialist circle. Diamandy and Lafargue encouraged him to extend his forays into critical social history. According to Sorel's own claim, his presence there was only made possible when non-revolutionary French socialists like Millerand had decided to boycott "L'Ère Nouvelle".
