A French king whose devastating mental illness plunged his kingdom into decades of civil war and paved the way for English domination.
Charles VI ascended the throne as a minor, inheriting a wealthy and powerful France. His early reign, guided by regents, showed promise. Then, in 1392, while on campaign, he suffered a sudden and violent psychotic break, attacking his own men. This was the first of many 'absences' that would define his 42-year rule. Believing he was made of glass and could shatter, or failing to recognize his own wife and children, Charles became a symbol of instability. His incapacity triggered a vicious power struggle between the royal dukes of Burgundy and Orléans, which spiraled into outright civil war. This internal chaos invited English invasion, leading to the catastrophic French defeat at Agincourt and the near-dismemberment of the kingdom he was too ill to rule.

He suffered from the 'glass delusion,' a medieval belief that one's body was made of glass and could break.
His wife, Isabeau of Bavaria, was effectively regent during his frequent bouts of illness.
The Bal des Ardents, a masquerade ball meant to cheer him, ended in a fatal fire when his costume caught flame.
