Jean-Guillaume de Neubourg-Wittelsbach
Charles Philip succeeded his brother Johann Wilhelm, Elector Palatine on his death in 1716. He moved the Palatinate's capital from Heidelberg to the new city of Mannheim in 1720, but not before promoting his favorite court jester, Perkeo of Heidelberg, to be in charge of the castle's wine stocks. To strengthen the union of all lines of the Wittelsbach dynasty Charles Philip organized a wedding on 17 January 1742 when his granddaughter Elizabeth Auguste was married to Charles Theodore of Palatinate-Sulzbach and her sister Maria Anna to the Bavarian prince Clement. In the imperial election a few days later Charles III Philip voted for his Bavarian cousin Prince-Elector Charles Albert.
