First referred to as "the Beloved" and later "the Mad," Charles VI ascended to the throne at the age of eleven and increasingly suffered from psychotic episodes that rendered him an ineffectual ruler. Although Charles signed the Treaty of Troyes shortly after the French defeat at the Battle of Agincourt, making his future son-in-law Henry V heir to the French throne, Henry died shortly before Charles, leading to the French re-entering the Hundred Years' War and earning victory for the French House of Valois.
