Münster

In 793, Charlemagne sent out Ludger as a missionary to evangelise the Münsterland. In 797, Ludger founded a school that later became the Cathedral School. Gymnasium Paulinum traces its history back to the school. Ludger was ordained as the first bishop of Münster. The first cathedral was completed by 850. The combination of ford and crossroad, market place, episcopal administrative centre, library and school, established Münster as an important centre. In 1040, Heinrich III became the first king of Germany to visit Münster.
Middle Ages and early modern period

In the Middle Ages, the Prince-Bishopric of Münster was a leading member of the Hanseatic League.

Part of the signing of the Peace of Westphalia of 1648 was held in Münster. This ended the Thirty Years' War and the Eighty Years' War. It also guaranteed the future of the prince-bishop and the diocese; the area was to be exclusively Roman Catholic.
