Policies
Count Philipp Ludwig II's policies are notable for their drive of modernisation for his tiny state. With his marriage, he came of age, although the regency continued for his younger brother Albrecht. By using his rights under the Cuius regio, eius religio rule, he changed the confession of his county to Calvinism. He succeeded with this nearly everywhere in his sphere of influence, except in a few villages in the district Bornheimerberg, which surrounded Frankfurt and the condominiums shared with the Roman Catholic archbishop-elector of Mainz. The villages in the vicinity of Frankfurt had strong ties to this Lutheran city and a majority of the villagers just went to Lutheran services in “foreign” Frankfurt territory. Also in the condominiums Philipp Ludwig II shared with the Archbishopric of Mainz he couldn’t change anything — whether they had become Lutheran during the reformation or had remained Roman Catholic. The introduction of Calvinism and its location, at only half a day’s journey away from Frankfurt with its trade fair, made Hanau an attractive place to settle for Calvinist refugees from France and later from the Southern Netherlands. They were often wealthy traders and were attractive subjects for a ruler in need of tax revenues. In 1597 and 1604, the count and the refugees entered into two treaties which gave them a large degree of self-government and founded the “New Town” of Hanau, south to the historic mediaeval settlement. This proved to be a big success and initiated an economic growth for Hanau which lasted even into the 19th century. Philipp Ludwig II also reinstated a Jewish community in Hanau. Space was allocated for the Jews on the southern fortifications of the historic town, which was no longer needed, due to the new town which protected this side of the old town. This Ghetto was not part of one either town, but placed directly under the administrative control of the county. Count Philipp Ludwig II also tried to found a university. He founded the “Hohe Landesschule” in Hanau. It was modeled on the Herborn Academy, where he had studied himself. Even so, it did not develop into a university and it still exists until today as a secondary school.
