 After multiple changes in ownership and having been pawned many times (noble families documented in this period include von Sickingen, von Rosenberg, von Menzingen, von Neipberg, von Gemmingen as well as the prince-bishops of Speyer), Dielheim finally came as a whole into the ownership of the prince-bishops of Speyer in 1512.The administrative seat of Dielheim for the prince-bishop was in Rotenberg.In the German Peasants' War in 1525, many farmers from Dielheim fought on the side of the so-called Mob of Malsch ("Malscher Haufens") against the oppression of the rule of the prince-bishops.
