Progressive ("automobile") Old Order Mennonites, like the Weaverland Conference Mennonites (USA), Wisler Mennonites (USA), and Markham-Waterloo Mennonite Conference (Canada), largely evolved from the same series of Old Order schisms from 1872 to 1901. Nowadays, they often share the same meeting houses with and adhere to almost identical forms of Old Order worship as their horse-and-buggy Old Order brethren with whom they parted ways in the early 20th century. Although Weaverland Old Orders began using cars in 1927, the cars were required to be plain and painted black. The form of the ban among progressive groups in general is less severe, which means an ex-communicant is not always shunned and is, therefore, not excluded from the family table, shunned by their spouse and/or cut off from business dealings. All progressive Old Orders have either already shifted from Pennsylvania German to English or are in the process to do so. In recent decades, however, family sizes and growth rates of the progressive groups have diminished compared to the horse-and-buggy groups.
