King Charles VI was a monarch of France who reigned from 1380 to 1422. He is often referred to as "Charles the Mad" due to his bouts of mental illness, which significantly affected his ability to govern. His reign was marked by the ongoing conflict known as the Hundred Years' War between France and England, which created political instability and division within the country. During his reign, Charles VI struggled to maintain control over his kingdom, leading to power struggles among the nobility. His mental health issues resulted in periods of incapacitation, allowing rival factions, such as the Burgundians and the Armagnacs, to vie for influence. His death in 1422 left France in a state of turmoil, setting the stage for further conflict.
