December 1641 CE
Richelieu had sent Mazarin in 1640 to Savoy, where the regency of Christine, the Duchess of Savoy, and sister of Louis XIII, is disputed by her brothers-in-law, the princes Maurice and Thomas of Savoy, and he succeeds not only in firmly establishing Christine but in winning over the princes to France.
This great service is rewarded by his promotion to the rank of cardinal on the presentation of the King of France in December 1641.
He returns soon after to Rome.
Nearing the end of his life, Richelieu has alienated many people, including Pope Urban VIII.
Richelieu is displeased by the Pope's refusal to name him the papal legate in France; in turn, the Pope does not approve of the administration of the French church, or of French foreign policy.
However, the conflict is largely healed when the Pope grants a cardinalate to Mazarin.
Despite troubled relations with the Roman Catholic Church, Richelieu does not support the complete repudiation of papal authority in France, as is advocated by the Gallicanists.
