Oneida (ōnĪˈdə) [key], city (1990 pop. 10,850), Madison co., central N.Y.; inc. 1901. Silverware is its best-known product; factories also manufacture industrial wire and cable, and paper and plastic goods. Nearby was the Oneida Community, a religious society of Perfectionists that was established (1848) by John Humphrey Noyes. Members of the sect held all property in common and practiced complex marriage and common care of the children. The community prospered by making steel traps and silverware. In 1881 it was reorganized as a joint stock company, and the social experiments were abandoned. The community's large Mansion House survives as a apartment residence, museum, and guesthouse.
