The Amish, formally the Old Order Amish, are a group of traditionalist Anabaptist Christian church fellowships with Swiss German and Alsatian origins. As they maintain a degree of separation from surrounding populations, and hold their faith in common, the Amish have been described by certain scholars as an ethnoreligious group, combining features of an ethnicity and a Christian denomination. The Amish are closely related to Old Order Mennonites and Conservative Mennonites—denominations that are also a part of Anabaptist Christianity. 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.

Anabaptism is a Christian movement which traces its origins to the Radical Reformation in the 16th century. Anabaptists believe that baptism is valid only when candidates freely confess their faith in Christ and request to be baptized. Commonly referred to as believer's baptism, it is opposed to baptism of infants, who are not able to make a conscious decision to be baptized.
