Biography

Contemporaries gave Philip II the name Augustus, and under his rule the territory and authority of the French crown grew more than under any king before him. The only son of Louis VII by his third wife, Adela of Champagne, Philip was crowned at Reims in 1179 during his father's final illness and became sole king in 1180. That year he married Isabella of Hainaut, who brought the county of Artois as her dowry and whose descent from the Carolingians allowed writers of the next generation to present their son, the future Louis VIII, as joining the old royal line to the new.

The central struggle of the reign was with the Plantagenet kings of England, whose continental possessions — Normandy, Anjou, Maine, Touraine and Aquitaine — dwarfed the Capetian domain. Philip intrigued with the sons of Henry II against their father, departed on the Third Crusade in 1190 alongside Richard I, and returned home after the fall of Acre in 1191 to work against Richard's interests. Against Richard he made limited headway, but the accession of John in 1199 gave him his opening: declaring John's French fiefs forfeit in 1202, he conquered Normandy by 1204 and soon afterward took Anjou, Maine and Touraine as well.

In July 1214, at Bouvines in Flanders, Philip defeated a coalition of the emperor Otto IV, the count of Flanders and allies financed by King John, a victory that confirmed his conquests and secured the kingdom. His matrimonial affairs were turbulent. After Isabella's death in 1190 he married Ingeborg, sister of the king of Denmark, in 1193, repudiated her almost immediately, and contracted a disputed marriage with Agnes of Merania, drawing an interdict on France from Pope Innocent III before he finally restored Ingeborg to her position as queen in 1213.

Philip also strengthened royal government, employing salaried officials known as baillis to administer the enlarged domain, walling Paris, paving its principal streets and beginning the fortress of the Louvre. He died at Mantes in July 1223 and was buried at Saint-Denis, succeeded by his son Louis VIII, husband of Blanche of Castile.

    Third Crusade

    1189 – 1192· as Co-leader; departed after the fall of Acre

    The destruction of the Latin army at Hattin and the surrender of Jerusalem in 1187 prompted the largest Western military response since the First Crusade. The papal call was answered by the three leading monarchs of Latin Europe: the emperor Frederick Barbarossa, who drowned crossing a river in Anatolia in June 1190, leaving his great army to disintegrate; Philip II of France; and Richard I of England, who had taken the cross as count of Poitou and inherited the Plantagenet dominions in 1189. Richard's journey east included the conquest of Cyprus from its Byzantine ruler in 1191, an acquisition that anchored Latin power in the eastern Mediterranean for centuries. The two kings joined the long siege of Acre, which had been invested by Guy of Lusignan since 1189 while Saladin's army in turn surrounded the besiegers. The city fell in July 1191. Philip, ill and at odds with Richard, returned to France soon afterward, where his maneuvering against Plantagenet lands shaped the rest of the war. Richard marched south along the coast, defeating Saladin's attack at Arsuf in September 1191 and refortifying Jaffa and Ascalon, but twice advanced toward Jerusalem and twice withdrew, judging that the city could not be held even if taken while Saladin's field army survived. Negotiations ran alongside the fighting, conducted largely through Saladin's brother al-Adil, and included proposals, never realized, for a marriage settlement involving Richard's sister. After Richard's relief of Jaffa in August 1192, both exhausted sides concluded the Treaty of Jaffa in September: a three-year truce confirming Latin control of the coast from Tyre to Jaffa, with Ascalon demolished, and guaranteeing Christian pilgrims access to Jerusalem, which remained under Ayyubid rule. Richard sailed for home and was captured in Austria; Saladin died in Damascus in March 1193.

    Battle of Bouvines

    1214· as commanding victor

    The decisive battle of medieval France. On 27 July 1214 Philip II Augustus crushed a coalition of the Holy Roman Emperor Otto IV, Count Ferdinand of Flanders, and the English under John, ending the Plantagenet attempt to recover the continental holdings John had lost a decade earlier. Bouvines confirmed France as the dominant power of Latin Europe and broke John's standing at home — the Magna Carta crisis followed within a year.
