The Shift in Franco-English Relations After Henry…

The Shift in Franco-English Relations After Henry II’s Death (1189)

The death of Henry II on July 6, 1189, combined with the fall of Jerusalem to Saladin in 1187, temporarily diverted attention from the ongoing war between France and England. However, while Philip II of France had once allied himself with Henry’s sons to undermine their father, he would soon turn against both Richard and John once they took the throne.

Philip viewed the Angevin kings of England—who also ruled Normandy, Aquitaine, and Anjou—as his most powerful and dangerous vassals. Determined to destroy Angevin power in France, Philip made it his life’s work to weaken and dismantle their territories, laying the groundwork for Capetian dominance in the 13th century.

Philip’s Manipulation of Henry II’s Sons

• Philip had befriended Henry II’s rebellious sons, using them to foment uprisings against their father.
• He had particularly maintained close ties with Henry the Young King and Geoffrey, Duke of Brittany, until their deaths in 1183 and 1186, respectively.
• Philip’s grief over Geoffrey’s death was notable—at Geoffrey’s funeral, he was reportedly so overcome with sorrow that he had to be forcibly restrained from throwing himself into the grave.

Philip’s New Strategy Against the Angevins

• With Richard I now on the throne, Philip shifted from being a manipulator of rebellious sons to becoming their direct adversary.
• Philip would soon turn against Richard, exploiting his absence during the Third Crusade (1189–1192) to undermine his control in France.
• After Richard’s death in 1199, Philip would manipulate John’s weaknesses, eventually seizing Normandy in 1204 and dismantling much of the Angevin Empire.

While Philip had once played the role of an ally and instigator, he would become the greatest enemy of the Plantagenets, initiating a struggle that would reshape the balance of power in medieval France and England.
