Most "Old Order" Mennonites emerged through divisions from the main body of Mennonites between 1872 and 1901 in four regions of North America: Indiana in 1872, Ontario in 1889, Pennsylvania in 1893 and Virginia in 1901. Conflicts over the introduction of such modern practices as Sunday Schools, revival meetings, and English-language preaching drove the formation of Old Order Mennonite churches. These modernizing trends that changed the form of religious practice were pushed among the Mennonites especially by two men: John F. Funk and John S. Coffman. The traditionally minded people left the old conferences to form new ones, but not the modernizers.
