The Amish (ˈɑːmᵻʃ; Amisch; Amische), formally the Old Order Amish, are a group of traditionalist Anabaptist Christian church fellowships with Swiss German and Alsatian origins. They are closely related to Mennonite churches, a separate Anabaptist denomination. The Amish are known for simple living, plain dress, Christian pacifism, and slowness to adopt many conveniences of modern technology, with a view neither to interrupt family time, nor replace face-to-face conversations whenever possible, and a view to maintain self-sufficiency. The Amish value rural life, manual labor, humility and Gelassenheit (submission to God's will).
The Amish church began with a schism in Switzerland within a group of Swiss and Alsatian Mennonite Anabaptists in 1693 led by Jakob Ammann. Those who followed Ammann became known as Amish. In the second half of the 19th century, the Amish divided into Old Order Amish and Amish Mennonites; the latter do not abstain from using motor cars, whereas the Old Order Amish retained much of their traditional culture. When people refer to the Amish today, they normally refer to the Old Order Amish, though there are other subgroups of Amish. In the early 18th century, many Amish and Mennonites immigrated to Pennsylvania for a variety of reasons. Today, the Old Order Amish, the New Order Amish, and the Old Beachy Amish as well as Old Order Mennonites continue to speak Pennsylvania Dutch, although two different Alemannic dialects are used by Old Order Amish in Adams and Allen counties in Indiana. , over 350,000 Old Order Amish lived in the United States, and about 6,000 lived in Canada: a population that is rapidly growing, even though most Amish clearly seem to use some form of birth control, a fact that generally is not discussed among the Amish, but indicated by the fact that the number of children systematically increases in correlation with the conservatism of a congregation, the more conservative, the more children. Amish church groups seek to maintain a degree of separation from the non-Amish world.
