An'abap'tists, a name given to a Christian sect because, as they objected to infant baptism, they baptized all those who joined them. In 1520, owing to the influence of Munzer and others, Switzerland became a center for Anabaptists, from which they spread to the Netherlands and Westphalia. In 1534 the town of Munster in Westphalia was their center of action. Bockhold became leader, assuming the name of John of Leyden, king of the New Jerusalem and the city was the scene of cruelty, fanaticism and crime until the Protestant princes put an end to it.
