Georges Sorel
The new political group, called "Cercle Proudhon", was founded on 16 December 1911. It included Berth, Valois, Lagrange, the syndicalist Albert Vincent and the royalists , René de Marans, André Pascalon, and Marius Riquier. As the name "Cercle Proudhon" suggests, the group was inspired by Pierre-Joseph Proudhon. It was also inspired by Georges Sorel and Charles Maurras. In January 1912 the journal of "Cercle Proudhon" was first published, entitled "Cahiers du cercle Proudhon".
