From Wikipedia:
The Oneida Community was a utopian commune founded by John Humphrey Noyes in 1848 in Oneida, New York. The community believed that Jesus Christ had already returned in the year 70, making it possible for them to bring about Christ's millennial kingdom themselves, and be free of sin and perfect in this world, not just Heaven (a belief called Perfectionism).
The Oneida Community practiced Communalism (in the sense of communal property and possessions), Complex Marriage, Male Continence, Mutual Criticism and Ascending Fellowship. There were smaller Noyesian communities in Wallingford, Connecticut; Newark, New Jersey; Putney, Vermont; and Cambridge, Vermont. In Putney, the authorities attempted to have Noyes arrested for his unorthodox sexual practices. The community's original 87 members grew to 172 by February 1850, 208 by 1852 and 306 by 1878. The branches were closed in 1854, except for the Wallingford branch, which operated until devastated by a tornado in 1878.
The Oneida Community dissolved in 1881, and eventually became the giant silverware company Oneida Limited.
