After the death of Henry IV., Marie de' Medici succeeded in having herself made queen-regent for Louis XIII., who was then but nine years old. A woman of no particular capacity, who had in no way adapted herself to French life and customs, she allowed herself to be governed by an adventurer, an Italian who understood and appreciated French ideals no more than did Marie; these two--the queen and Concini, her minister--immediately began to concoct plans to gain control of the state. The king was kept in virtual captivity until he reached the age of seventeen, when, having asserted his rights, Concini was killed, and Marie's dominant power and influence came to an abrupt end.
Louis XIII. reigned, with his minister, the Prince de Luynes, from 1617 to 1624, when he became reconciled to his mother and appointed her favorite, Richelieu, his minister. From 1610 to about 1640, Marie de' Medici exercised more or less influence, always of a nature disastrous to France.
After the king's death, Anne of Austria, as queen-regent, with Mazarin, directed the destinies of France. During the ministry of the two cardinals, Richelieu and Mazarin, occurred the political intrigues and astute diplomatic movements of Mme. de Chevreuse and the unwise and short-sighted aspirations of Mme. de Longueville. These intimate friends were women of the highest intelligence, most perfect beauty, and uncapitulating devotion, and were working for the same cause, though from different motives.
Mme. de Chevreuse was the daughter of M. de Rohan, Duke of Montbazon. She had married M. de Luynes, the minister of Louis XIII., who overthrew the power of Marie de' Medici, and who, by initiating his wife into his secrets, gave her the schooling and experience which she later used to such advantage. De Luynes presented her at court with instructions to ingratiate herself with the queen--Anne of Austria--and the king. In this design she succeeded so well that she was soon made superintendent of the household of the queen, and became as influential with Anne as was her husband with the king.
In 1621 M. de Luynes died; a year later his widow married Claude of Lorraine, Duke of Chevreuse; but as that was an unhappy union, she soon began her career as an intriguer. On the arrival of Lord Kensington, the English ambassador, she fell in love with him, that escapade being the first of a long series; the two proceeded to inveigle Queen Anne into a liaison with the Duke of Buckingham, which scheme, as history so well records, partly succeeded.
When Mme. de Chevreuse accompanied to England the new queen, Henriette-Marie, wife of Charles I., both Buckingham and Kensington outdid themselves in showing her attention, Richelieu, fearing her influence and intrigues at the court of England, hastened the recall of her husband, but she received through her friends, from the English monarch himself, an invitation to remain; during the time, she gave birth to a child.
Her next famous undertaking, which involved the lives of various persons of high rank, was the scheme to persuade Monsieur the Dauphin to refuse to marry Mlle. de Montpensier; Queen Anne was opposed to this union, and Mme. de Chevreuse gained to their cause a number of influential friends who were all madly in love with her. The ever vigilant Richelieu having discovered the plot, Monsieur confessed. In this conspiracy, M. de Chalais lost his head, other plotters lost their positions, and some were exiled. Mme. de Chevreuse was forced to retire to Lorraine; there she set in movement a vast plan against Richelieu and France, allying England and various princes, but, by the arrest of Montaigu, the plot was discovered, the alliance broken up, and peace restored.
In 1626, by request of England, Mme. de Chevreuse returned to France. For a time she was quiet and seemed to favor Richelieu, but she soon captivated one of his ministers, the Marquis of Châteauneuf. Richelieu discovered the latter's weakness, and, having captured his correspondence, sent him to prison, where he remained for ten years. The fair intriguer was exiled to Dampierre, the cardinal fearing to send her out of France on account of her influence with the Duke of Lorraine. She managed to steal into Paris at night and see the queen; when discovered, she was sent to Touraine where she began the dangerous task of carrying on the correspondence between the Dukes of Savoy and Lorraine and England, and between Spain and Queen Anne. Even when this correspondence was intercepted and the queen confessed all, Richelieu was afraid to banish Mme. de Chevreuse; though he believed her to be at the bottom of all the current intrigues, he knew that out of France she would stir up the rulers of England and Spain as well as the Duke of Lorraine and others hostile to the cardinal.
Violence being out of the question, because of her influence in England and of the prominence of her family, he decided to win her over by kindness; he even sent her money, but she was too shrewd to permit Richelieu to outwit her, always paying him back in his own coin. However, that kind of play was too dangerous for her and she escaped to Spain. As soon as her departure became known, Richelieu set to work every means in his power to bring her back, sending her an urgent invitation to return and promising to pardon her past. When his messages reached her, she was already in Madrid, where she was royally received as the friend of the king's sister, Anne; there, by means of her beauty and wonderful intelligence, she conquered every cavalier. When the war broke out between France and Spain, she left for England where she was welcomed like a visiting queen.
Richelieu, anxious for the support of the Duke of Lorraine in his war against Spain and Austria, needed the coöperation of Mme. de Chevreuse, and with that end in view sent ambassadors to London to arrange for her return; but an agreement was not an easy matter between two such astute politicians, and negotiations went on unsuccessfully for over a year. Her subtleness, apparent docility and invincible precautions were pitted against the artifices and dissimulation of the cardinal; both employed all the astute manoeuvres of diplomacy and exhausted the resources of consummate skill in gaining the point desired by each. The cardinal failed to convince her of her safety.
