In 1240, a third of the village came into the ownership of the Hersfeld Monastery. There was a noble family, the Lords of Ohmes, but they died out in the 13th century. The other two thirds of the village belonged to the court district of Katzenberg under the Counts of Ziegenhain, with its seat at Ruhlkirchen. The one constant in Ohmes's history during the Middle Ages was change, and the village saw a whole series of rulers, from various lords who held the Katzenberg, to the Teutonic Knights, to Hans von Dornberg the Landgrave of Hesse, and above all the Archbishopric of Mainz.
