Étienne Cabet was a French philosopher and utopian socialist who founded the Icarian movement. Cabet became the most popular socialist advocate of his day, with a special appeal to artisans who were being undercut by factories. Cabet published Voyage en Icarie in French in 1839, in which he proposed replacing capitalist production with workers' cooperatives. Recurrent problems with French officials, led him to emigrate to the United States in 1848. Cabet founded utopian communities in Texas and Illinois, but was again undercut, this time by recurring feuds with his followers.
