Affairs, however, took a very different turn. Mazarin and others, the creatures of and successors to Richelieu, were less arrogant, less ambitious, and less resolute than their master. They were willing to acquire power by allying themselves to the adverse party. Mazarin, in particular, felt that, on the death of Louis XIII., he should not possess influence enough to cope with the persons who, by rank, were destined to the regency; and he perceived, at once, that it was his best policy to become the friend, instead of the rival, of the queen and the duke of Orleans. Anne of Austria saw safety in encouraging him in this conduct. Mazarin grew into a favourite, and supplanted those who had stood by her during her years of adversity. Thus, while the surface of things appeared the same, the spirit was changed. Rochefoucauld saw that the queen entertained new views and new partialities, and was supported by the same party by which she had been hitherto oppressed. As her friend, he perceived the advantages she gained by this line of conduct, and, by prudent concessions, retained her regard. When the king died, and she became regent, Mazarin had made himself necessary to her, for it was by his policy that the other members of the council of the regency were reduced to insignificance; so that the queen, entirely attached to him, anticipated with something of aversion the reappearance of madame de Chevreuse, who, on the death of Louis XIII., hastened 1643 to return to Paris. [Sidenote: 1643. Ætat. 30.] The prince of Marsillac perceived her apprehensions, and asked her permission to meet madame de Chevreuse on her way, which the queen readily granted, hoping that the prince would dispose her former friend to seek the friendship of Mazarin. This was, indeed, Marsillac's purpose: he gave the fallen favourite the best advice that prudence could suggest, and the duchess promised to follow it. In this she failed. She fancied that she could supplant the cardinal in the queen's favour; she acted with arrogance; and her imprudence insured her ruin.
