In her thirteenth year, after being sought by many powerful princes, Clement VII. (her greatuncle), in order to secure himself against the powerful Charles V., married her to Henry, Duke of Orleans, the second son of Francis I. Even at that early age she was fully aware of all the dreariness and danger attached to positions of power, and knew that the art of governing was not an easy one. She had studied Machiavelli's famous work, The Prince, which had been dedicated to her father, and it was from it, as well as from her ancestors, that she derived her wisdom and astuteness. Her childhood had prepared her for the work of the future, and she went at it with caution and reserve until she was sure of her ground.
She first proceeded to study the king, Francis I., watching his actions, extracting his secrets; a fine huntress and at his side constantly, she pleased him and gained his favor. Brantôme says she was subtle and diplomatic, quickly learning the craft of her profession; she sought friends among all classes and ranks, directing her overtures specially toward the ladies of the court, whom she soon won and gathered about her.
In 1536 the dauphin died, and Catherine's husband became heir to the throne of France. Though they had been married three years, no offspring had resulted, which unfortunate circumstance made her position a most uncertain one, especially as Diana of Poitiers was then at the height of her power, controlling Henry absolutely. A furious rivalry sprang up between the Duchesse d'Etampes, mistress of Francis I., and Diana and Catherine; the two mistresses formed two parties, and a war of slanders, calumnies, and unpleasant epigrams ensued. Queen Eleanor, the second wife of Francis I., took no active part, thus leaving all power in the hands of the mistress of her husband. (It was at this time that the Emperor Charles V. gained the Duchesse d'Etampes over to his cause.) Poets and artists, politicians and men of genius took sides, extolling the beauty of the one they championed. Catherine, although befriended and treated with apparent respect by Diana, remained a good friend to both women, thus evincing her tact. By keeping her own personality in the background, she won the esteem of both her husband and the king.
Brantôme leaves a picture of Catherine at this time: "She was a fine and ample figure; very majestic, yet agreeable and very gentle when necessary; beautiful and gracious in appearance, her face fair and her throat white and full, very white in body likewise.... Moreover, she dressed superbly, always having some pretty innovation. In brief, she had beauties fitted to inspire love. She laughed readily, her disposition was jovial, and she liked to jest." M. Saint-Amand continues: "The artistic elegance that surrounded her whole person, the tranquil and benevolent expression of her countenance, the good taste of her dress, the exquisite distinction of her manners, all contributed to her charm. And then she was so humble in the presence of her husband! She so carefully avoided whatever might have the semblance of reproach! She closed her eyes with such complaisance! Henry told himself that it would be difficult to find another woman so well-disposed, another wife so faithful to her duties, another princess so accomplished in point of instruction and intelligence. The ménage à trois (household of three) was continued, therefore, and if the dauphin loved his mistress, he certainly had a friendship for his wife. And, on her part, whenever she felt an inclination to complain of her lot, Catherine bethought herself that if she quitted her position she would probably find no refuge but the cloister, and that--taking it all around--the court of France (in spite of the humiliations and vexations one might experience there) was an abode more desirable than a convent;" this, then, is the secret of her submission. In spite of her beauty, mildness, and distinction of manner, she could not overcome the prestige of Diana.
After nine years, Catherine was still without children and began to fear the fate in store for her; but when she gave birth to a son in 1543, she felt assured that divorce no longer threatened her and she resolved that as soon as she came into power she would be revenged upon her enemies and Diana of Poitiers. When, in 1547, her husband succeeded his father as King of France, she did not feel that the time had yet arrived to interfere in any social or domestic arrangements or affairs of state; not until ten years later did she show the first sign of remarkable statesmanship or ability as a politician.
After the battle and capture of Saint-Quentin, France was in a most deplorable state; the enemy was believed to be beneath the walls of Paris; everybody was fleeing; the king had gone to Compiègne to muster a new army. Catherine was alone in Paris "and of her own free will went to the Parliament in full state, accompanied by the cardinals, princes, and princesses; and there, in the most impressive language, she set forth the urgent state of affairs at the moment.... With so much sentiment and eloquence that she touched the heart of everybody, the queen then explained to the Parliament that the king had need of three hundred thousand livres, twenty-five thousand to be paid every two months; and she added that she would retire from the place of session, so as not to interfere with the liberty of discussion; accordingly, she retired to another room. A resolution to comply with the wishes of her majesty was voted, and the queen, having resumed her place, received a promise to that effect. A hundred nobles of the city offered to give at once three thousand francs apiece. The queen thanked them in the sweetest form of words, and thus terminated this session of Parliament--with so much applause for her majesty and such lively marks of satisfaction at her behavior, that no idea can be given of them. Throughout the city, nothing was spoken of but the queen's prudence and the happy manner in which she proceeded in this enterprise" (Guizot). From this act dates Catherine's entrance into political consideration.
During the reign of Francis II., Catherine de' Medici exercised no influence at court, the king being completely under the dominion of his wife and the Duke of Guise, who was not favorable to the queen-mother's schemes and policies. Catherine, however, was plotting; caring little about religion so long as it did not further her plans, she connected herself with the Huguenots; her scheme was to bring the Guises to destruction and to form a council of regency which, while composed of the Huguenot leaders, was to be under her guidance. As this plan failed, bringing ruin to many princes, she deserted the Huguenots and allied herself with the Catholics.
She is next found attempting the assassination of the Duke of Condé, but she failed to accomplish that crime because her son, the king, refused his consent. Soon after, Francis II. died, it is said from the effect of poison dropped into his ear while he was sleeping; it is probable that this crime was committed at the instigation of the mother, since by his death and the accession of Charles IX. she became regent (1560). She was then all-powerful and in a position to exercise her long dormant talents.
Her first plan was to incapacitate all her children by plunging them "into such licentious pleasure and voluptuous dissipation that they were speedily unfitted for mental activity or exertion." Most unprejudiced historians credit her with the Massacre of Saint Bartholomew; she is said to have boasted about it to Catholic governments and excused it to Protestant powers. For a number of years, she had been planning the destruction of the Huguenot princes, and as early as 1565 she and Charles IX. had an interview with the Duke of Alva (representative of Philip II), to consult as to the means of delivering France from heretics. It was decided that "this great blessing could not have accomplishment save by the deaths of all the leaders of the Huguenots."
That fearful crime, the bloody Massacre of Saint Bartholomew, is familiar to everyone. The only excuse offered for this most heinous of Catherine's many offences is her intense sentiment of national unity; the actual reason for it is to be sought in the fact that as long as the Protestants retained their prestige and influence, Catherine and her Catholic party could not do as they pleased, could not gain absolute control over the government. History holds her more responsible than it does her weak son. The climax came on the occasion of the wedding of Marguerite of Valois with the Prince of Navarre, which meant the union of the branches--the Catholic and the Protestant. This resulted in the first breach between the king and Catherine; the latter at that time perpetrated one of her dastardly deeds by poisoning the mother of the Prince of Navarre--Jeanne d'Albret, her bitter enemy.
