Charles VI of France

Charles VI (3 December 1368 – 21 October 1422), nicknamed the Beloved (French: le Bien-Aimé) and in the 19th century, the Mad (French: le Fol or le Fou), was King of France from 1380 until his death in 1422. He is known for his mental illness and psychotic episodes that plagued him throughout his life, including glass delusion.

Charles ascended the throne at age 11, his father Charles V leaving behind a favorable military situation, marked by the reconquest of most of the English possessions in France. Charles VI was placed under the regency of his uncles: Philip II, Duke of Burgundy; Louis I, Duke of Anjou; John, Duke of Berry; and Louis II, Duke of Bourbon. He decided in 1388, aged 20, to emancipate himself. In 1392, while leading a military expedition against the Duchy of Brittany, the king had his first attack of delirium, during which he attacked his own men in the forest of Le Mans. A few months later, following the Bal des Ardents (January 1393) where he narrowly escaped death from burning, Charles was again placed under the regency of his uncles, the Dukes of Berry and Burgundy.

From then on, and until his death, Charles alternated between periods of mental instability and lucidity. Power was held by his influential uncles and by his wife, Queen Isabeau. His younger brother, Louis I, Duke of Orléans, also aspired to the regency and saw his influence grow. The enmity between the Duke of Orléans and his cousin John the Fearless, successor of Philip the Bold as Duke of Burgundy, plunged France into the Armagnac–Burgundian Civil War of 1407–1435, during which the king found himself successively controlled by one or the other of the two parties.
