As duke of Orleans he had certain claims to Milan through his grandmother Valentina, dap~hter of Gian Galeazzo, the first duke.
By the peace of Chartres (March 9, 1409) the king absolved him from the crime, and Valentina Visconti, the widow of the murdered duke, and her children pledged themselves to a reconciliation; while an edict of the 27th of December 1409 gave John the guardianship of the dauphin.
His foreign policy, which was directed wholly towards Italy, was for the most part unskilful; to his claims on Naples he added those on Milan, which he based on the marriage of his grandfather, Louis of Orleans, with Valentina Visconti.
But he complicated the Naples affair by claiming Milan in consideration of the marriage of his grandfather, Louis of Orleans, to Valentina, daughter of Gian Galeazzo Visconti, duke of Milan.
