Amish

Refers to the conservative Anabaptist sect led by Jakob Amman that separated from the Mennonites in Switzerland around 1693. The development of more liberal sects occurred after many Amish migrated to the United States, particularly in the 1870s. Only the Old Order Amish (founded 1720-1740) still maintain Amman's strict dress codes, customs, and policy of non-cooperation with the state. Today, the Amish exist mainly in southeastern Pennsylvania.
