The Treaty of Troyes was signed in 1420 during the Hundred Years' War between England and France. This agreement recognized Henry V of England as the heir to the French throne, effectively disinheriting the French Dauphin, Charles VII. The treaty aimed to solidify English control over France and was a significant moment in the conflict. However, the treaty was not widely accepted in France and faced opposition. After Henry V's death in 1422, the situation changed, leading to the eventual rejection of the treaty by the French. This contributed to the ongoing struggle for power between the English and the French, ultimately influencing the course of the war.
