 Charles VI's uncle, Philip the Bold, Duke of Burgundy, thought the proposed marriage ideal to build an alliance with the Holy Roman Empire and against the English. Isabeau's father agreed reluctantly and sent her to France with his brother, her uncle, on the pretext of taking a pilgrimage to Amiens. He was adamant that she was not to know she was being sent to France to be examined as a prospective bride for Charles, and refused permission for her to be examined in the nude, customary at the time. According to the contemporary chronicler Jean Froissart, Isabeau was 13 or 14 when the match was proposed and about 16 at the time of the marriage in 1385, suggesting a birth date of around 1370.
