In the 1870s, he founded in New York the Koreshan Unity, a commune whose rule of conduct was based on his teachings. Other similar communities were established in Chicago and San Francisco. After 1894 the group concentrated itself in the small Florida town of Estero, seeking to build a "New Jerusalem" in that locale, peaking at 250 residents during the first decade of the 20th Century. Following Teed's death late in 1908 the group went into decline, finally disappearing in 1961, leaving the Koreshan State Historic Site behind.
