On 21 May 1535, at his second Consistory for the promotion of cardinals, Pope Paul III created seven new cardinals, among them Jean du Bellay. He was named Cardinal Priest of the "titulus" of Santa Cecilia in Trastevere on 31 May. His cardinal's hat was sent to him in France on 3 April. Beginning on 27 June he made the journey to Rome, stopping in Ferrara for negotiations with the Duke about the war over Milan, and then moving on to Rome, where he appeared personally for his induction ceremonies at the Consistory of 6 August. He had additional reasons, however, for going to Rome. He was sent by King Francis to seek papal assistance against the aggression of the Emperor Charles V in the struggle for the Duchy of Milan. He was again accompanied by François Rabelais.
