If he had had progeny, they would have had a strong claim upon the throne of Sweden after the line of his brother, Charles X Gustav of Sweden, ended with Ulrika Eleonora. Since he had no progeny, the throne was claimed by the heirs of his eldest sister Christina Magdalena of the Palatinate-Zweibrücken.
