 In 1455, Frederick I, Elector Palatine claimed in a feud letter – one used to declare a feud – sent to his cousin Louis I, Count Palatine of Zweibrücken that he had been done a disservice "im Riche zu Rade Seelberg" (“in the realm at Rothselberg”).Thus, it is known that at this time, Rothselberg lay in the Electorate of the Palatinate.Rothselberg remained in the Electorate of the Palatinate until feudalism was abolished in the course of the French Revolution.
