Müncheberg is a small town in Märkisch-Oderland, in eastern Germany approximately halfway between Berlin and the border with Poland, within the historic region of Lubusz Land. The settlement was founded between 1225 and 1232 by Cistercian monks who had been given the land by the Piast Duke of Lower Silesia and soon-to-be monarch of Poland, Henry I the Bearded. A citation in a document from June 29, 1232, marks the official date of the founding. This first settlement was called Lubes by the monks in honor of the monastery in Lubiąż in Lower Silesia, Poland, where they originally came from. This name was not kept for long and in February 1233 the settlement was first mentioned as Munichberc in a charter by Pope Gregory IX. The settlement grew quickly and gained town privileges in 1245. The increasing prosperity led to the construction of a 7-metre-high city wall in 1319. After a war broke out over control of the region in 1319, the town came under the control of the Duchy of Pomerania. In 1319, Wartislaw IV granted new privileges to the town. In 1324, the town passed to Brandenburg, and between 1373 and 1415 it was part of the Bohemian Crown.
