In 1401, King Ruprecht raised Alzenau to town, but the town never exercised its rights (until 1951) and remained a market community. From 1309 comes the first documentary record. The contents of this document deal with the "Freigericht" (“Free Court”) with four court regions, the so-called "Hohe Mark". Since the first half of the 13th century the royal hunting forest had been owned by the Archbishopric of Mainz. In 1395, the whole market community passed to the Archbishopric. This part of Alzenau's history is recalled by the six-spoked wheel – the so-called Wheel of Mainz – which was a charge borne by the Archbishops in their arms. The two twigs refer to the court officials who were chosen from among the townsmen to be on the court.
