Greatness of soul, real moral force, strict virtue, are not attributes of the sixteenth-century woman—they are isolated and rare exceptions; these Catherine did not possess. Nor was she influenced deeply by her environments; the latter but encouraged and developed those qualities which were hers inherently,—will, intelligence, inflexible perseverance, tenacity of purpose, unscrupulousness, cruelty; hence, to say "She is the victim rather than the inspiration of the corruption of her time" is misleading, to say the least. If, upon her arrival at court, "she at once pleased every one by her grace and affability, modest air, and, above all, by her extreme gentleness," she could not have changed, say her defenders, into the perfidious, wicked, and cruel creature she is said to have become as soon as she stepped into power. "During the reign of Henry II., she wisely avoided all danger; faithful to her wifely duties, she gave no cause for scandal, and, realizing that she was not strong enough to overcome her all-powerful rival, she bided her time. She was loved and respected by everyone for her personal qualities and her benevolence." But why may it not be true that all this was but part of her politics, the politics in which she had been educated? Wise from experience, she foresaw the future and what was in store for her if she remained prudent and made the best of the surroundings until the time should come when she could strike suddenly and boldly.

Brought up from infancy amidst snares, intrigues, the clash of arms, the furious shouts of popular insurrections, tempests, and storms, she could not escape the influence of her early environment. Her talent for studying and penetrating the designs of her enemies, for facing or avoiding dangers with such sublime calmness and prudence, was partly inherited, partly acquired. That spirit she took with her to France, where her experience was widened and her opportunities for the study of human nature were increased.

It is not generally known that her mother was a French woman—a Madeleine de La Tour d'Auvergne, daughter of Jean, Count of Boulogne, and Catherine of Bourbon, daughter of the Count of Vendôme; thus, her gentler nature was a French product. Her mother and father both died when she was but twenty-two days old, and from that time until her marriage she was cast about from place to place. But from the very first she showed that talent of adapting herself to her surroundings, living amidst intrigues and discords and yet making friends. She has been called "the precocious heiress of the craftiness of her progenitors."

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.
