Isabeau of Bavaria

Isabeau of Bavaria, born in 1370, was a significant figure in French history as the Queen consort of King Charles VI from 1385 until 1422. The only daughter of Duke Stephen III of Bavaria-Ingolstadt and Taddea Visconti of Milan, Isabeau was sent to France at the tender age of fifteen or sixteen to marry the young king. Their marriage was formalized just three days after their first meeting, and in 1389, she was honored with a grand coronation ceremony in Paris.

As Charles VI's mental health deteriorated, beginning with his first episode in 1392, Isabeau found herself navigating a complex political landscape. Despite the king's desire to distance himself from her during his illness, he permitted her to act on his behalf, which led to her assuming the role of regent for their son, the Dauphin of France. This position granted her unprecedented power for a medieval queen consort, allowing her to influence the regency council significantly.

The power vacuum created by Charles' illness ignited the Armagnac–Burgundian Civil War, as factions vied for control. Isabeau adeptly shifted her allegiances to secure the best outcomes for her son. However, her political maneuvers led to accusations of infidelity with the Duke of Orléans from the Burgundians, and she faced imprisonment when the Armagnacs took control. The assassination of Orléans in 1407 by John the Fearless intensified the conflict, which ultimately concluded with her son's act of vengeance against John in 1419.

In 1420, Isabeau was present at the signing of the Treaty of Troyes, which controversially declared that the English king would inherit the French crown after her husband's death. Following this, she lived in English-occupied Paris until her passing in 1435. Over the centuries, Isabeau has often been portrayed as a spendthrift and irresponsible, yet modern historians have begun to reassess her legacy, suggesting that much of the negative perception stemmed from political propaganda and factional rivalries.
