This was a prolonged conflict lasting from 1337 to 1453 between two royal houses for the French throne, which was vacant with the extinction of the senior Capetian line of French kings. The two primary contenders were the House of Valois and the House of Plantagenet, also known as the House of Anjou.
The House of Valois claimed the title of King of France, while the Plantagenets from England claimed to be Kings of France and England. The Plantagenet Kings in England had their roots in the French regions of Anjou and Normandy. French soldiers fought on both sides, with Burgundy and Aquitaine providing notable support for the Plantagenet side.The conflict lasted 116 years but was punctuated by several brief periods of peace, and two lengthy periods of peace, before it finally ended in the expulsion of the Plantagenets
from France (except the Pale of Calais). The war was a victory for the house of Valois, who succeeded in recovering the Plantagenet gains made initially and expelling them from the majority of France by the 1450s
