The Treaty of Bourges was an agreement between Henry IV, King of England and Charles, Duke of Orléans signed on 18 May 1412.
[1] In November 1407, Louis I, Duke of Orléans was assassinated, starting a civil war in France between the Armagnacs and the Burgundians.
This treaty also stipulated that Poitou and Angoulême, possessions of John of Berry and Charles of Orléans, were to be held by them of the English crown and would be handed over to the King of England upon the death of the two princes.
As part of the agreement, Thomas of Lancaster, Duke of Clarence, devastated western France south of the Loire.
