Harmony Society in the context of "New Harmony, Indiana"

In Greek mythology, Harmonia (/hɑːrˈmoʊniə/; Ancient Greek: Ἁρμονία /harmoˈnia/, "harmony", "agreement") is the goddess of harmony and concord. Her Greek opposite is Eris and her Roman counterpart is Concordia. Harmonia is most well-known for her marriage to Cadmus and the many misfortunes that haunted her descendants, particularly those related to the fabled Necklace of Harmonia.

Old Economy Village is an historic settlement that is located in Ambridge, Beaver County, Pennsylvania, United States. Administered by the Pennsylvania Historical and Museum Commission, it lies on the banks of the Ohio River and is surrounded by downtown Ambridge.

The village is the last of three settlements established by the Harmony Society in the United States (another in Pennsylvania and one in Indiana). Founded in 1824, it was designated as a National Historic Landmark District in 1966 under the name of "Old Economy."

John George Rapp (German: Johann Georg Rapp; November 1, 1757 – August 7, 1847) was the founder of the religious sect called the Harmony Society and a number of associated communes.

Born in Iptingen, Germany, Rapp became inspired by the philosophies of Jakob Böhme, Philipp Jakob Spener, and Emanuel Swedenborg, among others. In the 1780s, George Rapp began preaching and soon started to gather a group of his own followers. His group officially split with the Lutheran Church in 1785 and was promptly banned from meeting. The persecution that Rapp and his followers experienced caused them to leave Germany and come to the United States in 1803. Rapp was a Pietist, and a number of his beliefs were shared by the Anabaptists, as well as groups such as the Shakers.
