Greek `baptize again' a member of any of various 16th-century radical Protestant sects. They believed in adult rather than child baptism, and sought to establish utopian communities. Anabaptist groups spread rapidly in N Europe, particularly in Germany, and were widely persecuted. Notable Anabaptists included those in Moravia (the Hutterites) and Thomas Muntzer (1489-1525), a peasant leader who was executed for fomenting an uprising in Muhlhausen (now Mulhouse in E France). In Munster, Germany, Anabaptists controlled the city 1534-35. A number of Anabaptist groups, such as the Mennonites, Amish, and Hutterites, emigrated to N America, where they became known for their simple way of life and pacifism.
