John of Leiden

Dutch religious reformer
Also known as: Jan Beuckelson

Quick Summary

John of Leiden, born Jan Beuckelson, was a Dutch religious reformer and a prominent leader of the radical Anabaptist movement. He became known for his role in the Münster Rebellion of 1534–35, where he, along with other Anabaptist leaders, established a theocratic kingdom in Münster, Germany.1

The Anabaptists, a fringe group of the Protestant Reformation, advocated for adult baptism, believing that infant baptism was invalid. They also called for a separation of church and state and were often pacifists.1

In Münster, under the influence of figures like Jan Mathijs and John of Leiden, the Anabaptists expelled non-Anabaptists and implemented practices such as communal ownership of goods and polygamy. This radical experiment ended when the city was besieged and recaptured by an army of Catholics and Protestants in 1535. John of Leiden and other leaders were subsequently tortured and executed. The Münster Rebellion is often viewed as an aberration within the broader Anabaptist movement, which largely continued as a pacifist tradition, notably through the Mennonites led by Menno Simons.1
