In the time of the pledging to the counts palatine of the Rhine from 1461 to 1650, Bensheim experienced a boom, but as a Palatinate town, however, it was embroiled in the Bavarian-Palatine war of succession in 1504, and for eleven days was unsuccessfully besieged by the Landgrave of Hesse, who was charged with the execution of the ban of the Empire, and his confederates, the Dukes Henry of Brunswick and Henry of Mecklenburg. From this year, two yearly markets and one weekly can be established; a third yearly market came in 1619.
