Louis VII (1120 – 18 September 1180), was King of France from 1137 to 1180. His first marriage was to Duchess Eleanor of Aquitaine, one of the wealthiest and most powerful women in western Europe. The marriage temporarily extended the Capetian lands to the Pyrenees.
Louis was the second son of Louis VI of France and Adelaide of Maurienne, and was initially prepared for a career in the Church. Following the death of his older brother, Philip, in 1131, Louis became heir apparent to the French throne and was crowned as his father's co-ruler. In 1137, he married Eleanor of Aquitaine and shortly thereafter became sole king following his father's death. During his march, as part of the Second Crusade in 1147, Louis stayed at the court of King Géza II of Hungary on the way to Jerusalem. During his stay in the Holy Land, disagreements with Eleanor led to a deterioration in their marriage. She persuaded him to stay in Antioch but Louis instead wanted to fulfil his vows of pilgrimage to Jerusalem. He was later involved in the failed siege of Damascus and eventually returned to France in 1149. Louis' reign saw the founding of the University of Paris. He and his counsellor, Abbot Suger, pushed for greater centralisation of the state and favoured the development of French Gothic architecture, notably the construction of Notre-Dame de Paris.
Louis' marriage to Eleanor was annulled in 1152 after the couple had produced two daughters, but no male heir. Immediately after their annulment, Eleanor married Henry, Duke of Normandy and Count of Anjou, to whom she conveyed Aquitaine. Following Henry's accession as King Henry II of England, these territories formed the Angevin Empire. Later, Louis supported Henry and Eleanor's sons in their rebellion against their father to foment further disunity in the Angevin realms. His second marriage to Constance of Castile also produced two daughters, but his third wife, Adela of Champagne, gave birth to a son, Philip Augustus, in 1165. Louis died in 1180 and was succeeded by his son, Philip II.
Louis was born in 1120, the second son of Louis VI of France and Adelaide of Maurienne. The early education of the young Louis anticipated an ecclesiastical career. As a result, he became well learned and exceptionally devout, but his life course changed decisively after the accidental death of his older brother Philip in 1131, when Louis unexpectedly became the heir to the throne of France. In October 1131, his father had him anointed and crowned by Pope Innocent II in Reims Cathedral. He spent much of his youth in Saint-Denis, where he built a friendship with the abbot Suger, an advisor to his father who also served Louis during his early years as king.
Following the death of Duke William X of Aquitaine, Louis VI moved quickly to have his son married to Eleanor of Aquitaine (who had inherited William's territory) on 25 July 1137. In this way, Louis VI sought to add the large, sprawling territory of the duchy of Aquitaine to his family's holdings in France. On 1 August 1137, shortly after the marriage, Louis VI died, and Louis became king. The pairing of the monkish Louis and the high-spirited Eleanor was doomed to failure; she reportedly once declared that she had thought to marry a king, only to find she had married a monk. There was a marked difference between the frosty, reserved culture of the northern court in the Île-de-France, where Louis had been raised, and the rich, free-wheeling court life of the Aquitaine with which Eleanor was familiar. Louis and Eleanor had two daughters, Marie and Alix.
In the first part of his reign, Louis was vigorous and zealous in the exercise of his prerogatives. His accession was marked by no disturbances other than uprisings by the burgesses of Orléans and Poitiers, who wished to organise communes. He soon came into violent conflict with Pope Innocent II, however, when the archbishopric of Bourges became vacant. The king supported the chancellor Cadurc as a candidate to fill the vacancy against the pope's nominee Pierre de la Chatre, swearing upon relics that so long as he lived, Pierre should never enter Bourges. The pope thus imposed an interdict upon the king.
Louis then became involved in a war with Theobald II of Champagne by permitting Raoul I of Vermandois, the seneschal of France, to repudiate his wife, Theobald II's sister, and to marry Petronilla of Aquitaine, sister of the queen of France. As a result, Champagne decided to side with the pope in the dispute over Bourges. The war lasted two years (1142–1144) and ended with the occupation of Champagne by the royal army. Louis was personally involved in the assault and burning of the town of Vitry-en-Perthois. At least 1,500 people who had sought refuge in the church died in the flames. Condemned by the ecclesiastical authorities, Louis removed his armies from Champagne and returned them to Theobald. He accepted Pierre de la Chatre as archbishop of Bourges and shunned Raoul and Petronilla. Desiring to atone for his sins, he declared his intention of mounting a crusade on Christmas Day 1145 at Bourges. Bernard of Clairvaux assured its popularity by his preaching at Vezelay on Easter 1146.
In the meantime, Geoffrey V, Count of Anjou, completed his conquest of Normandy in 1144. In exchange for being recognised as Duke of Normandy by Louis, Geoffrey surrendered half of the county of Vexin—a region vital to Norman security—to Louis. Considered a clever move by Louis at the time, it would later prove yet another step towards Angevin rule.
In June 1147, in fulfillment of his vow to mount the Second Crusade, Louis and his queen set out from the Basilica of Saint-Denis, first stopping in Metz on the overland route to Syria. Soon they arrived in the Kingdom of Hungary, where they were welcomed by the king Géza II of Hungary, who was already waiting with King Conrad III of Germany. Due to his good relationships with Louis, Géza II asked the French king to be his son Stephen's godfather. Relations between the kingdoms of France and Hungary remained cordial long after this time: decades later, Louis's daughter Margaret was taken as wife by Géza's son Béla III of Hungary.
After receiving provisions from Géza, the army continued its march to Constantinople. After meeting with Manuel and receiving some supplies, the French crusaders moved to join up with Conrad's army. Louis conferred with Conrad and decided to wait for the Germans to reorganize before joining him at Lopadium. Louis set out on what he assumed would be simpler paths into Philadelphia. Concerned about the winter shortage of supplies in hostile, Seljuk-held central Anatolia, Louis and Conrad made the decision to alter their journey by 11 November. After a month of travel Louis' army arrived at Ephesus. He chose, despite warning from Byzantine messengers, to march inland towards the Maender valley. Just beyond Laodicea, at Mount Cadmus, the French army was ambushed by Turks. In the resulting battle, the Turks first bombarded the French with arrows and heavy stones, then swarmed down from the mountains and massacred them. The historian Odo of Deuil gives this account:
During the fighting the King Louis lost his small and famous royal guard, but he remained in good heart and nimbly and courageously scaled the side of the mountain by gripping the tree roots [...] The enemy climbed after him, hoping to capture him, and the enemy in the distance continued to fire arrows at him. But God willed that his cuirass should protect him from the arrows, and to prevent himself from being captured he defended the crag with his bloody sword, cutting off many heads and hands.
After this battle, Louis refused to travel by land any further and boarded ships at Adalia. He finally reached Antioch in March 1148. His queen Eleanor supported her uncle, Raymond of Poitiers, and prevailed upon Louis to help Antioch against Aleppo. But Louis' interest lay in Jerusalem, and so he slipped out of Antioch in secret and went to Jerusalem. He united with King Conrad III of Germany and King Baldwin III of Jerusalem to lay siege to Damascus; this ended in disaster and the campaign was abandoned after just four days. Louis decided to leave the Holy Land, despite the protests of Eleanor, who still wanted to help her doomed uncle Raymond, after Easter of 1149. Departing from Acre, he returned to France via Italy, and after visiting Roger II of Sicily and Pope Eugene III, crossed the Alps and reached Paris in November.
