This is the first complete account of the epic tale of the Icarians and their dream of creating a perfect society without money or property. Robert P. Sutton analyzes the origins of Icarianism in the milieu of French politics in the 1840s, discusses its founder Etienne Cabet, and traces the eventual creation of six communal societies in Illinois, Iowa, and California between 1848 and 1898. Les Icariens is a fascinating amalgam of biography, a history of French Socialism, and the story of one of the longest-lived secular communal experiments in America.
