Jakob Ammann
Jacob Amman (Jakob Ammann) was born circa 1644 in Erlenbach im Simmental, Switzerland, but later moved to Alsace as part of a wave of Anabaptist emigration from out of the Canton of Berne. His exact date of birth is unknown. Some believe he is the Jakob Ammann who was born on Feb. 12, 1644, to Michael and Anna Rupp Ammann of Erlenbach. Ammann lived in the region of Ste. Marie-aux-Mines, Upper Alsace, in 1696. On February 27 of that year, he signed a petition against compulsory military service. He was probably leader of that congregation until his death. Ammann's date of death is also unknown, though records indicate it occurred after 1708 and before 1730. Ammann's name is found on a 1708 list that Mennonites were required to sign by Alsace authorities. An Erlenbach record of his daughter's baptism in 1730 mentions that he had died prior to the event.
In 1693, Jakob Ammann took issue from out of Alsace with Swiss Mennonite leaders Hans Reist and Benedict Schneider in regards to what he saw as a lack of overall discipline in the Mennonite congregations. This lack of discipline, he believed, was exemplified with the shying away from the implementation of the ban against those who left the church after being baptised in the church. In 1693 disagreements over the implementation of the ban would come to a head between Hans Reist and Jakob Ammann and this would result in the Jakob Ammann faction splitting from the Mennonites. Amman was highly influenced by the Dutch Mennonite beliefs, and instituted the practice of feet washing in connection with communion, which was not practiced by the Swiss Mennonites. He also increased holding communion to twice a year, differing from the Swiss practice of annual communion services. Later in life, Jakob Ammann would regret his actions and would make attempts for Amish reunification with the Mennonites, even apparently offering to ban himself from his own congregation in order to show his regret for the disunity that he believed he had helped cause. Despite admissions of being rash and overzealous, the Amish would not give up the belief of practicing the ban (or Meidung). Because of this, the main body of Amish and the Swiss Mennonites were never able to reconcile. Most of the Amish left in Europe after the American migration reunited with the Mennonites. Some joined other bodies. Amish no longer exist as a European body.
