Under the April 1559 Peace of Cateau-Cambrésis which ended the Italian Wars, France renounced its claims in Italy, but gained certain other territories, including the Pale of Calais and the Three Bishoprics. These acquisitions strengthened French borders while the abdication of Charles V, Holy Roman Emperor in January 1556 and division of his empire between Spain and Austria provided them with greater flexibility in foreign policy. Nostradamus also served King Henry as physician and astrologer.
