Her marriage, previously mentioned, to Henry of Navarre was a mere political match, there being absolutely no love, no affection, no sympathy. This union was looked upon as the surest covenant of peace between Catholicism and Protestantism and put an end to the disastrous religious wars that had been carried on uninterruptedly for years; both the parties to this contract lived at court, leading an existence of pleasure and immorality. Remarkably intelligent, Marguerite was a scholar of no mean ability; she displayed much wit and talent, but no judgment or discretion; though conveying the impression of being rather haughty and proud, she lacked both self respect and true dignity. Her beauty was marvellous, but "calculated, to ruin and damn men rather than to save them." Henry, the husband of Marguerite, was constantly sneered at and taunted by the Catholics; although Catholic in name he was Protestant at heart and keenly felt his false position. During Catherine's short term as queen-regent, he was held in captivity until the arrival of Henry III., when he escaped to his own Béarn people; for this, Marguerite was held responsible and kept under guard. Although hating his religion, his wife went to live with him, tolerating his infidelities while he refused to tolerate her religion. The unhappiness of this marriage was not due to Marguerite alone; the first trouble arose when she discovered his love for his mistress, Gabrielle d'Estrées, and, thinking herself equally privileged, she began to indulge in the same excesses. The result of so many annoyances and debaucheries, so much vexation, was an illness; as soon as she became convalescent, she returned to her mother at court where she speedily gained the ill will of the king by her profligate habits, her quarrels with both Catholics and Protestants, her intimacy with the Duke of Guise, her plottings with her younger brother, her cutting satires on court favorites. She was sent back to Henry, upon the way meeting with the mishap of being insulted by archers and, with her maids, led away prisoner. Her husband was with difficulty persuaded to receive her, and, finding him all attentive to his mistress, Marguerite fled to Agen, where she made war upon him as a heretic; unable to hold her position there on account of her licentious manner of living and the exorbitant taxes imposed upon the inhabitants, she fled again and continued moving from one place to another, causing mischief everywhere, "consuming the remainder of her youth in adventures more worthy of a woman who had abandoned her husband than of a daughter of France." At last, she was seized and imprisoned in the fortress of Usson; here she was supported mainly by Elizabeth of Austria, widow of Charles IX.
