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.

Pennsylvania Dutch, sometimes referred to as Pennsylvania German, is a variation of Palatine German spoken by the Pennsylvania Dutch, including the Amish, Mennonites, Fancy Dutch, and other related groups in the United States and Canada. There are approximately 300,000 native speakers of Pennsylvania Dutch in the United States and Canada.
