The "free love" Oneida Community, founded in New York state during the turbulent decades before the Civil War, practiced an extraordinary system of "complex marriage" as part of its sustained experiment in creating the kingdom of heaven on earth. For more than thirty years, two hundred adult members considered themselves heterosexually married to the entire community rather than to a single monogamous partner.  Free Love in Utopia provides the first in-depth account of how complex marriage was introduced among previously monogamous or single Oneida Community members. Bringing together vivid, firsthand writings by members of the community--including personal correspondence, memoranda on spiritual and material concerns, and official pronouncements--this volume portrays daily life in Oneida and the deep religious commitment that permeated every aspect of it. It also presents a complex portrait of the community's founder, John Humphrey Noyes, who demanded not only complete religious loyalty from his followers but also minute control over their sexual lives. It recounts the formidable legal suits faced by the community--one of which almost forced it to disband in 1852--and the critical behind-the-scenes work of Noyes's second-in-command, John L. Miller. Most important, Free Love in Utopia describes in detail how Oneida's "enlarged family" was created and how its unorthodox practices affected its members.   Key selections from a large collection of primary documents detailing Oneida's early years were compiled by George Wallingford Noyes, nephew of the founder. The present volume, astutely edited and introduced by noted communitarian scholar Lawrence Foster, marks the first publication of G. W. Noyes's remarkable manuscript, excerpted from the irreplaceable original documents that were deliberately burned after his death. The volume also reproduces Oneida's First Annual Report, which contains the sexual manifesto that underlay the community.
