ISABELLA, ISABEAU, or ELIZABETH OF BAVARIA (1370– '435), wife of Charles VI. of France, was the daughter of Stephen II., duke of Bavaria. She was born in 1370, was married to Charles VI. on July 17, 1385, and crowned at Paris on Aug. 22, 1389. She fell under the influence of the dissolute court in which she lived, and the king having become insane (August 1392) she consorted chiefly with Louis of Orleans. After the assassination of the duke of Orleans (Nov. 23, 1407) she attached herself some times to the Armagnacs, sometimes to the Burgundians, and led a scandalous life. Following the murder of John the Fearless
she went over to the side of the English, into whose hands she surrendered France by the treaty of Troyes (May 21, 1420), at the same time giving her daughter Catherine in marriage to the king of England, Henry V. She died in Sept. 1435, and was interred without funeral honours in the abbey of St. Denis.
