The final blow to this policy came in 1529, when the French made peace with Charles. Meanwhile, the French also continued to honour the "Auld Alliance" with Scotland, stirring up hostility on England's border. With peace between France and the Emperor, there was no-one to free the Pope from Charles, who had effectively held Pope Clement VII captive since the Sack of Rome (1527). There was thus little hope of securing Henry VIII an annulment from his marriage to Charles's aunt Catherine of Aragon. Since 1527, Wolsey's desire to secure an annulment for his master had dictated his foreign policy, and by 1529 none of his endeavours had succeeded.
