King John of England in his first year or two of rule achieved some successes, but his lack of tact and diplomacy, plus poor decision-making lost him many allies in France. The focus of the escalating conflict between the Plantagenets and Capetians became Chateau Gaillard, a magnificent fortress in the key borderlands between Normandy and the French royal demesne around Paris.
