Jean-Guillaume de Neubourg-Wittelsbach
Louis George was aged five and as such, Sibylle was created the Regent of Baden-Baden in the name of her son. Sibylle's has been credited with the reconstruction of Baden-Baden, a state which had been ravaged greatly by the French during their various wars prior to Louis George's birth. Sibylle held a tight rein on the states finances and by the time of Louis George's majority in 1727, the state was once again flourishing and she had considerably augmented his own personal fortune. Whenever she could, she made pilgrimages to the next secular advisors, such as Leopold, Duke of Lorraine and the Elector Johann Wilhelm, Elector Palatine. She also sought spiritual support too.
