The Amish (; Pennsylvania Dutch: Amisch, ) are a group of traditionalist Christian church fellowships, closely related to but distinct from Mennonite churches, with whom they share Swiss Anabaptist origins. The Amish are known for simple living, plain dress, and reluctance to adopt many conveniences of modern technology. The history of the Amish church began with a schism in Switzerland within a group of Swiss and Alsatian Anabaptists in 1693 led by Jakob Ammann. Those who followed Ammann became known as Amish.
