Abstract: A former Saint-Simonian, but critical of the elitist direction taken by the school with Prosper Enfantin, Pauline Roland (1805-1852) became close to Pierre Leroux and his doctrine of Humanity. She explored possible alternatives to inegalitarian capitalism and reflected on the links between socialism and the Republic. This text details the characteristics of the democratic and social republic that Pauline Roland envisages within workers' associative practices.
