New Harmony, originally Harmony, was one of the earliest Utopian Experiments in the United States. 
George Rapp started the Harmonist Society in 1814. Their first community was in Pennsylvania and was called Harmony. After deciding to leave Pennsylvania, they settled in Indiana and began another town called Harmony. Around 1824, they sold the land and buildings to Robert Owen and moved back to Pennsylvania to start Economy, now known as Ambridge. Owen changed the name to New Harmony and recruited settlers to join him.
