After the
German Peasants' War (1524–1525), a forceful attempt to establish theocracy was made at
Münster, in
Westphalia (1532–1535). Here the Anabaptists had gained considerable influence, through the adhesion of
Bernhard Rothmann, the
Lutheran pastor, and several prominent citizens and leaders, including
Jan Matthys (also spelled Matthijs, Mathijsz, Matthyssen, Mathyszoon), a baker from
Haarlem, and
Jan Bockelson (or Beukelszoon), a tailor from
Leiden.
Bernhard Rothmann was a tireless and vitriolic opponent of Catholicism and a writer of pamphlets that were published by his ally, the wealthy wool merchant
Bernhard Knipperdolling. The pamphlets at first denounced Catholicism from a radical Lutheran perspective, but soon started to proclaim that the Bible called for the absolute equality of man in all matters, including the distribution of wealth. The pamphlets, which were distributed throughout northern Germany, called upon the poor of the region to join the citizens of Münster to share the wealth of the town and benefit spiritually from being
the elect of Heaven. With so many Anabaptist adherents in the town, Rothmann and his allies had little difficulty obtaining possession of it at the elections for the magistracy and placing Bernhard Knipperdolling as the mayor, after deposing the mainly Lutheran magistrates, who, until then, had seen him as an ally in their own distrust of, and dislike for, Catholics. Matthys was a follower of
Melchior Hoffman, and after Hoffman's imprisonment at Strasbourg Matthys obtained a considerable following in the
Low Countries, including Bockelson, who became known as
John of Leiden. John of Leiden and Gerrit Boekbinder had visited Münster, and returned with a report that Bernhard Rothmann was in Münster teaching doctrines similar to their own. Matthys identified Münster as the "
New Jerusalem", and on January 5, 1534, a number of his disciples entered the city and introduced
adult baptism. Rothmann apparently accepted "baptism" that day, and well over 1000 adults were soon baptised. Vigorous preparations were made not only to hold what had been gained but to spread their beliefs to other areas. The many Lutherans who left were outnumbered by the arriving Anabaptists. There was a wave of
iconoclasm in cathedrals and monasteries, and rebaptism became compulsory. The property of emigrants was shared out with the poor, and soon a proclamation was issued that all property was to be held in common. ==Siege==
