The settlement was founded in 1852. Among the settlers there was
John D. Lee. It was also the original headquarters of
the Church of Jesus Christ of Latter-day Saints's Southern Indian Mission. Settlers were driven from Fort Harmony when the fort had to be abandoned after most of its adobe walls were washed away after the month long rains during the
Great Flood of 1862.
New Harmony and
Kanarraville, in
Iron County were the settlements created by refugees from this disaster later in 1862. ==See also==
