French Queen. Wife of King Charles VI. Born into a prominent Bavarian family related by marriage or blood to many titled royalty throughout Europe. Both her uncle and the uncle of her future husband agreed that Isabeau's marriage to the Charles VI, future King of France would strengthen several alliances and arranged it when she was still 13. After careful coaching in the French manner of dress and speech, she was finally presented to Charles in July of 1385. Charles found her to be attractive and acceptable and they were married three days after their meeting. Charles then departed on a military campaign, she went to live with the Queen Dowager Blanche who continued her French education. By September of 1385, she took up residence in the Chateau de Vincennes. She was crowned queen four years later. In 1392, Charles began to suffer what is believed to be attacks of paranoid schizophrenia. Although their marriage in the beginning was considered a true love match, it rapidly disintegrated when Charles often did not recognize his wife. While others jostled to steal authority during the king's episodes, Isabeau remained loyal and was determined to retain the crown for their heirs. She became a skilled diplomat in navigating court politics and intrigue and successfully negotiated an alliance between France and Florence. In one of his lucid periods, Charles appointed Isabeau to be principal guardian of the Dauphin, which awarded her power on the regency council. He trusted her enough that in 1402, he gave her control of the treasury. Despite her best efforts, the Armagnac-Burgundian Civil War began in 1411. Henry V of England took advantage of this internal strife to invade France, delivering a shocking loss to the French at Agincourt. By 1417, two of Isabeau's sons had died, leaving the last son, Charles, to be disinherited by the King in 1419. Henry V used this to his advantage and at the Treaty of Troyes, allowed Charles VI to remain king, but at his death the crown would revert to Henry. Isabeau would remain living in Paris, but withdrew from public life, spending her remaining days at the Hotel du-Pol. She was an avid art collector and left her estate to Notre Dame, St. Denis and a convent in Poissy.
