John of Leiden was a Dutch Anabaptist leader. In 1533 he moved to Münster, capital of the Prince-Bishopric of Münster, where he became an influential prophet, turned the city into a millenarian Anabaptist theocracy, and proclaimed himself King of New Jerusalem in September 1534. The insurrection was suppressed in June 1535 after Prince-Bishop Franz von Waldeck besieged the city and captured John. John was tortured to death in the city's central marketplace on 22 January 1536, along with Bernhard Knipperdolling and Bernhard Krechting.

Münster is an independent city in North Rhine-Westphalia, Germany. It is in the northern part of the state and is considered to be the cultural centre of the Westphalia region. It is also a state district capital. Münster was the location of the Anabaptist rebellion during the Protestant Reformation and the site of the signing of the Treaty of Westphalia ending the Thirty Years' War in 1648. Today, it is known as the bicycle capital of Germany.
