The Icarians were a French-based utopian socialist movement, established by the followers of politician, journalist, and author Étienne Cabet. In an attempt to put his economic and social theories into practice, Cabet led his followers to the United States of America in 1848, where the Icarians established a series of egalitarian communes in the states of Texas, Illinois, Iowa, Missouri, and California. The movement split several times due to factional disagreements.

The last community of Icarians, located a few miles outside Corning, Iowa, disbanded voluntarily in 1898. The 46 years of tenure at this location made the Corning Icarian Colony one of the longest-lived non-religious communal living experiments in US history.
