And if he joined the Protestant leader Gustavus Adolphus in a religious crusade, it was with this end in view.
The marriage of Louis with the Infanta of Spain, known as Anne of Austria, was doubtless a part of the same line of policy, and was the beginning of many attempts to draw the Spanish peninsula under the control of France.
When the end of all these schemings arrived, on the 4th day of December, 1642, Richelieu calmly laid down to die in his princely residence known at that time as the Palais Cardinal.

But as it was his dying gift to the king, the name was changed to the Palais Royal.

Upon the death of Louis XIII., which occurred in 1643, only a few months after that of his minister, the widowed Queen Anne, with her infant son, Louis XIV., removed from the Louvre to the Palais Royal, which continued to be the residence of the Grand Monarch for some time after his majority.
Anne was appointed regent for her son, not yet five years old, and, to the surprise of everyone, immediately called to her aid as her adviser not a Frenchman, as was expected, but an Italian, Cardinal Mazarin.

So the fate of the kingdom was in the hands of two foreigners, a Spanish queen-regent and an Italian minister.
Richelieu's and Mazarin's methods were the opposite of each other.

One was direct, the other tortuous and indirect.
