Over the years, as Amish churches have divided many times over doctrinal disputes, subgroups have developed. The "Old Order Amish", a conservative faction that withdrew in the 1860s from fellowship with the wider body of Amish, are those that have most emphasized traditional practices and beliefs. There are many different subgroups of Amish with most belonging, in ascending order of conservatism, to the Beachy Amish, New Order, Old Order, or Swartzentruber Amish groups.
