Following the beginning of the
Wars of the Roses in 1455, England was not in a position to pursue its
claim to the French throne. Edward's position as King had been unstable during his first reign and was troubled by the war's progression in the 1460s. Edward was temporarily removed in 1470 and replaced with
Lancastrian Henry VI. By 1471, Henry VI and his son
Prince Edward had died, allowing Edward IV to reclaim the throne. Now with a more secure domestic situation, Edward IV was preparing to launch a military campaign against France, possibly in the hopes of regaining some of the territories which had been lost in the
Hundred Years War. It is unclear how serious Edward's intentions were to invade France, but his preparations for the war faced resistance from the
English parliament. Additionally, there was a lack of support from allies
Brittany and Burgundy. == Treaty ==
