During the late 18th century the Radical Pietist movement throughout the Duchy of Württemberg increased again after having diminished over the previous decades. Many Pietists separated from church for religious reasons. In Württemberg, where Rottenacker belonged to, those religious dissenters were generally known as 'separatists'. Since 1785 the linen weaver George Rapp from Iptingen became the most important leader of the Separatists in Württemberg, directing about 2,000 followers. When Rapp emigrated to the United States in 1803, a Separatist group from Rottenacker took over the leading role within the movement. It had been initiated in 1800 by a farmgirl named Barbara Grubenmann from Teufen in the Swiss canton Appenzell-Ausserrhoden south of Lake Constance who had come to Rottenacker. About 70 inhabitants of the village separated from church. From the beginning political ideas played an important role when the separatists insulted the ruler of Württemberg, the Elector Friedrich (1797-1803 Duke Friedrich II, 1806-1816 King of Württemberg) and his officials. In May 1804, the Elector sent military to the villages of Rottenacker, Dettingen unter Teck, Horrheim and Boll. The most prominent Separatists were arrested and led to the Fortrass of Asperg near Ludwigsburg in central Württemberg where many of them remained prisoners for a long time. When some parents refused to send their children to school the pupils were taken away to the orphanage at Stuttgart, the capital of Württemberg.
In 1811, some Separatists from Rottenacker bought the local 'Vogthaus' (today the Protestant ministry) near the church where they lived in a community of goods. Six years later, together with Separatists from other villages, they acquired an estate named Brandenburg near the border to Bavaria where they intended to found a community based on their religious principles. However, King Friedrich of Württemberg refused permission.
Therefore, a group of Separatists from Württemberg led by Joseph Michael Bimeler from Ulm and Stephan Huber from Rottenacker emigrated to the United States in 1817 and went to Ohio where they founded a communal society at Zoar. There, they lived in a community of goods where all private property was abolished. After Joseph Bimeler died in 1853, a younger generation was no more willing to share their property with others, and therefore the Zoar Society was dissolved in 1898.
Today, Zoar Village is a museum where many of the buildings from the Separatist era can still be visited.
- Johannes Breimaier (born January 24, 1776 at Rottenacker, died August 15, 1834 at Zoar, Ohio, separatist. He initiated the community of goods in Zoar in 1819. A newspaper report in English about Zoar and other religious communities in the United States made a strong impression on Friedrich Engels who was busy writing the Communist Manifesto published in 1848.
