The Longhouse Religion is the popular name of the religious movement known as The Code of Handsome Lake or Gaihwi:io (Good Message), founded in 1799 by the Seneca prophet Handsome Lake (Sganyodaiyoˀ). This movement combines and reinterprets elements of traditional Iroquois religious beliefs with elements adopted from Christianity, primarily from the Quakers. Gaihwi:io currently has about 5,000 practicing members.
