Amish Mennonites came into existence through reform movements among North-American Amish mainly between 1862 and 1878. These Amish moved away from the old Amish traditions and drew near to the Mennonites to become Mennonites of Amish origin. Over the decades most Amish Mennonites groups removed the word "Amish" from the name of their congregations or merged with Mennonite groups.
In the last decades the term "Amish Mennonite" is sometimes erroneously used to designate horse and buggy Old Order Mennonites, whose lifestyle is more or less similar to the Old Order Amish. Sometimes the term "Amish Mennonite" is used to designate all groups of Amish, both the Old Order Amish and the Amish Mennonites and also the Amish before this split in the late 19th century. The Global Anabaptist Mennonite Encyclopedia Online uses the term "Amish Mennonite" in this sense.
From 1862 to 1878, annual conferences were held among the Amish. The conferences produced a number of polarized groups, with two primary divisions: the Old Order Amish and the Amish Mennonites. The Amish Mennonites formed regional conferences in the late 1880s after the division. During the early 20th century, most of these original Amish Mennonite groups merged with regional Mennonite conferences and lost their Amish identity.
- The Indiana-Michigan Amish Mennonite Conference, began in 1888 and merged with the Indiana-Michigan Mennonite Conference in 1916.
- The Western District Amish Mennonite Conference, began in 1890 and merged with the Western Mennonite Conferences in 1920-1921.
- The Eastern Amish Mennonite Conference, began in 1893 and merged with the Ohio Mennonite Conference in 1927.
- The Stuckey Amish (Mennonites) of Illinois, began in 1899 and joined the General Conference Mennonite Church as a district conference in 1945. In 1957 it merged with the Middle District Conference to form the Central District of the General Conference Mennonite Church. 
- The Leatherville Amish Mennonites of Missouri
- The Egli Amish also known as the Égly Amish (Amish Mennonites) were organized as the Defenseless Mennonite Church in 1865–1866. They adopted the name Evangelical Mennonite Church in 1949 and became mainstream. While Evangelical Mennonite Churches currently exist, in 2003, a broader group of Mennonites became the Fellowship of Evangelical Churches.
The "Conservative Amish Mennonite Conference" was born several decades after the original Amish Mennonite movement. In 1910, leaders from three unaffiliated Amish Mennonite congregations met in Michigan to discuss the formation of a conference that allowed for congregational autonomy yet would be able to assist individual churches with problems. This conference was to be more conservative than the aforementioned Amish Mennonite conferences. Nonetheless it moved closer to mainstream Mennonite groups, eventually losing its Amish identity. In 1954, a majority vote called for the removal of the "Amish" part of the Conservative Amish Mennonite Conference (CMC) name, which was implemented in the 1957 constitution revision. Proponents suggested that "Amish Mennonite" conferences were obsolete. During the 1960s, concern rose among some about the lax practice on issues such as the women’s head veiling and cut hair, television, and clothing items. Individual churches began to differ greatly in practice. Since the concerns in the 1960s, conference has abandoned a stand on the aforementioned practices
Leading the process of assimilation further the "Ohio Mennonite and Eastern Amish Mennonite Joint Conference" became the "Ohio and Eastern Mennonite Conference" in 1955 and the "Ontario Amish Mennonite Conference" became the "Western Ontario Mennonite Conference" in 1963.
Kauffman Amish Mennonite
The Kauffman Amish Mennonites, also called Sleeping Preacher Churches or Tampico Amish Mennonite Churches, are a Plain branch of the Amish Mennonites whose tradition goes back to John D. Kauffman (1847-1913) who preached while being in trance. In 2017 they had some 2,000 baptized members and lived mainly in Missouri and Arkansas. In contrast to other Amish Mennonites they have largely retained the Pennsylvania German language and other traditions from the late 1800s. They allow some modern conveniences, such as electricity and cars. The Kauffman Amish Mennonite congregations are one of a few groups that clearly identifies itself as an Amish Mennonite constituency.
Beachy Amish Mennonites
The largest and most dominant contemporary Amish Mennonite group are the Beachy Amish Mennonites. The Beachy Amish received their name from Moses M. Beachy, a former Old Order Amish bishop in Somerset County, PA. Beachy refused to administer a strict form of shunning against members whose only offense was transferring membership to the nearby Conservative Amish Mennonite congregation. Half of the congregation sided with Beachy, and the other half sided with co-ministers Yoder and Yoder. Beachy's congregation affiliated with a similar Amish Mennonite congregation in Lancaster County, today known as the Weavertown Amish Mennonite Church. During the 1940s, a number of other factions emerged in Ohio, Indiana, Illinois, Iowa, Kansas, Oklahoma, and Virginia from Old Order Amish groups. The congregations sought affiliation with the Beachy constituency.
Today, the Beachy Amish vary widely in practice, as the constituency is a fellowship with congregational autonomy separate of a governing conference. Most have retained conservative, plain practices, but this is becoming increasingly questioned, especially in more mainstream churches in predominantly Old Order Amish areas, though not exclusively confined to these regions. New standard allowances in the more mainstream congregations include the radio and DVD or video watching. Clothing is also less distinct in these congregations, especially among the men; however, women's dress has become less distinguishable with a tighter fit and the wearing of sweaters or jackets, and coverings undergone abbreviation. However, the most conservative of Beachy congregations use German in services, refuse to have their photograph taken, and dress similar to the New Order Amish. Between these two range points is a wide variety of practice.
Mennonite Christian Fellowship
The Mennonite Christian Fellowship churches, also known as the "Fellowship churches", originated from several congregations separating from the Old Order Amish in the 1950s and 1960s. The congregations resembled the more conservative end of the Beachy Amish Mennonite constituency at that time. The two groups shared fellowship to the extent that these churches were incorporated into the Beachy affiliation. In 1977, however, some of the ordained men in these churches expressed concern about perceived worldly trends among the Beachy Amish. They met with other ordained Beachy Amish men. Some concerns included members baptized without a true Christian conversion, worldly fads in clothing and lifestyle, and churches conglomerating in communities instead of spreading out. After this meeting, the concerned men decided to withdraw from the Beachy Amish church fellowship, and organize the Mennonite Christian Fellowship. In 1978, these churches started holding their own annual Minister’s Meetings. They operate their own Christian day schools and use Sunday School materials printed by Rod and Staff Publishers of Crockett, Kentucky. They have sponsored missions in Nicaragua, Costa Rica, Honduras, and Paraguay. In 2006, the Fellowship churches had 1,518 members in 34 congregations.
A number of other Amish Mennonite congregations exist in an independent, unaffiliated setting. Most identify themselves in name as Conservative Mennonites or conservative Amish Mennonite and may hold fellowship with various Beachy or conservative Mennonite congregations.
Two newer affiliated groups include Berea Amish Mennonite Churches and Ambassador Amish Mennonite Churches. There is also a small group of Old Beachy Amish congregations which still use the German Language.
Membership and congregations
Around the year 2000 there were 13 Amish Mennonite congregations in five states of the USA. Membership of these congregations was 1,222. There were also 16 unaffiliated Amish Mennonite congregations in nine states with 737 members.
The Amish Mennonite Directory, published by Abana Books, lists Amish Mennonite congregations within Beachy, Fellowship, and unaffiliated constituencies. The directory includes detailed information, including household demographic and occupational data. The directory was published in 1993, 1996, 2000, 2005, 2008, and 2011.
