Old Order Mennonites (Pennsylvania German: ) form a branch of the Mennonite tradition. Old Order are those Mennonite groups of Swiss German and south German heritage who practice a lifestyle without some elements of modern technology, still drive a horse and buggy rather than cars, wear very conservative and modest dress, and have retained the old forms of worship, baptism and communion. All Old Order Mennonites reject certain technologies (e.g., radio, television, Internet), but the extent of this rejection depends on the individual group. Old Order groups generally place great emphasis on a disciplined community instead of the individual's personal faith beliefs. The Pennsylvania German language is spoken and vigorous among all horse-and-buggy groups except the Virginia Old Order Mennonites, who lost their original language before becoming Old Order. There is no overall church or conference to unite all the different groups of Old Order Mennonites. In 2008–2009, a minority of Old Order Mennonites accepted automobiles, whereas a majority retain horse and buggy transportation. The total population of Old Order Mennonites can be estimated to be between 72,000 and 84,000 in 2021. Very conservative Plautdietsch-speaking Russian Mennonites, who may have a similar belief and lifestyle, are normally not called Old Order Mennonite. Names From the first Old Order division in Indiana in 1872 under bishop Jacob Wisler (1808–1889) until the middle of the 20th century, all Old Order Mennonites were called by many "Wisler Mennonites," "Old Order Mennonites, Wisler," even "Wislerites," or the like. In a few cases this usage has persisted, but today the term "Wisler Mennonites" normally refers to a certain subgroup, the Ohio-Indiana Mennonite Conference. Old Order Mennonites who do not use automobiles are either referred to as "horse and buggy Mennonites" or "team Mennonites" (the word for them in Pennsylvania German is ). Sometimes the term "Old Order Mennonites" is restricted to groups that do not use cars. "Automobile" Old Order Mennonites refer to those who split from horse-and-buggy Old Order groups. It is common to name groups after a bishop, in most cases the leading bishop during the time of division. History 19th century In the second half of the 19th century, the Old Order Movement emerged among Anabaptists of South German and Swiss origin in North America who spoke mostly Pennsylvania German. Most "Old Order" Mennonites emerged through divisions from the main body of Mennonites between 1872 and 1901 in four regions of North
