Both claimants, both Charles of Austria and Philip, had a legal right to the Spanish throne because Philip's grandfather, King Louis XIV of France and Charles's father, Leopold I, Holy Roman Emperor, were sons of Charles II's aunts, Anne and Maria Anna. Philip claimed primogeniture because Anne was older than Maria Anna. However, Philip IV had stipulated in his will the succession should pass to the Austrian Habsburg line, and the Austrian branch also claimed that Maria Theresa, Philip's grandmother, had renounced the Spanish throne for herself and her descendants as part of her marriage contract. This was countered by the French claim that it was on the basis of a dowry that had never been paid.Durant, Will. "The Age of Louis XIV", p.699. Simon and Schuster, New York 1963.
