William IX, Duke of Aquitaine

William was born in Poitiers on October 22, 1071, the son of Duke William VIII of Aquitaine and his third wife, Hildegarde of Burgundy ^[1]. His father had worked hard to secure this heir. The duke's earlier marriages had produced no surviving son, and because Hildegarde was related to him within the degrees forbidden by canon law, William VIII traveled to Rome to obtain papal recognition that the boy was legitimate ^[2]. The child grew up as the long awaited successor to a dynasty, the Ramnulfids, that had governed Poitou and Aquitaine since the ninth century.

The inheritance waiting for him was enormous. The duchy of Aquitaine, joined with Gascony and the county of Poitou, stretched from the Loire valley toward the Pyrenees, a territory larger than the lands controlled directly by the king of France ^[1]. Its courts at Poitiers and Bordeaux drew clerics, jurists, and singers, and the region's churches, including the abbey of Saint-Hilaire in Poitiers, were centers of Latin learning. Nothing certain is known about the boy's formal education, but his later verse shows easy command of rhythm, rhyme, and scriptural allusion, which points to careful schooling in his father's household ^[3].

William VIII died in 1086, leaving his son the duchy at the age of fifteen ^[2]. The teenager took power as William IX of Aquitaine and William VII of Poitou, a doubled numbering that has confused readers ever since. Neighboring lords tested the young ruler almost at once, and the early years of his rule were spent holding together a patchwork of vassals who obeyed the duke only when it suited them.

Marriage shaped the first phase of his adult career. Around 1088 or 1089 William wed Ermengarde, daughter of Count Fulk IV of Anjou, but the union quickly failed and was set aside without children ^[4]. In 1094 he married Philippa of Toulouse, daughter and heiress of Count William IV of Toulouse. Through her he claimed the county of Toulouse, and he pressed that claim with armies in 1098 and again in 1113, occupying the city for years at a stretch before local resistance and the rival house of Saint-Gilles pushed the Poitevins out ^[1]. The Toulouse question would trouble his descendants for generations, most famously when his granddaughter Eleanor revived the claim.

In 1101 William took the cross. Inspired by the success of the First Crusade, he mortgaged lands, gathered a large force, and marched east in the wave of expeditions now called the Crusade of 1101 ^[5]. The campaign ended in catastrophe. Turkish forces destroyed his army in Anatolia, at Heraclea, and the duke escaped with only a handful of companions before reaching Antioch and eventually Jerusalem as little more than a pilgrim ^[5]. The chronicler Orderic Vitalis reported that after his return William entertained audiences with witty, rhythmic accounts of his miseries in captivity and defeat, an early glimpse of the performer behind the prince ^[6].

Defeat abroad did not end his ambitions. Anyone asking who was William IX, Duke of Aquitaine in the years after 1102 would have met a ruler still determined to enlarge his power: he fought the counts of Toulouse, sparred with his own bishops, and kept a wary eye on the Capetian kings to the north. He was excommunicated around 1114 in a dispute over church rights and taxation, one of two such sentences he collected during his life ^[2].

William's lasting fame rests on eleven songs, preserved in later manuscripts, that make him the earliest troubadour whose work survives ^[3]. He wrote not in Latin but in Occitan, the spoken language of southern France, and he treated secular subjects: desire, boasting, friendship, loss, and the game of love. Scholars debate whether he invented this art or simply stands at the head of a tradition whose earlier practitioners left no trace, but no older vernacular lyric of this kind has come down from medieval Europe ^[7].

The surviving poems fall into distinct registers. Several are frankly obscene comic pieces addressed to male companions, full of swagger and sexual jokes. Others are tender songs about a distant lady, and these contain the seeds of fin'amor, the refined love ethic that later troubadours, and after them poets across Europe, developed into the conventions of courtly love ^[3]. One remarkable piece, sometimes read as a farewell composed when he feared death or departure on campaign, mourns the son he must leave behind and renounces the pride of his youth ^[7]. The range is startling: the same man wrote some of the dirtiest and some of the most delicate verse of his century.

Contemporaries noticed the novelty. William of Malmesbury, writing in England within a decade of the duke's death, described him as a reckless jester who carried his buffoonery to excess, while Orderic Vitalis called him bold, brave, and overly fond of amusement ^[6]. A later Occitan vida summed him up as one of the most courtly men in the world and one of the greatest deceivers of women, and added that he knew well how to sing and make verses ^[8]. Among William IX, Duke of Aquitaine achievements, this literary invention outweighs everything he did with an army.

His marriages and liaisons scandalized churchmen. With Philippa of Toulouse he had at least two children who shaped the future: a son, the future William X, born in 1099, and a daughter, Agnes, who later married King Ramiro II of Aragon ^[4]. The ducal couple were early patrons of Robert of Arbrissel, whose new foundation at Fontevraud attracted Philippa's devotion, but the marriage collapsed spectacularly.

Around 1115 William took as his mistress Amauberge, called Dangereuse, the wife of his own vassal Aimery I, viscount of Châtellerault ^[4]. He installed her in a tower of his palace at Poitiers, the Maubergeon, and according to tradition had her image painted on his shield, joking that he would bear her in battle as she had borne him in bed ^[6]. The affair earned him a second excommunication. The papal legate Giraud, who was bald, ordered him to give the woman up, and William was said to have answered that curls would grow on the legate's bare head before he parted from the viscountess ^[8]. Philippa withdrew to Fontevraud, where she died in 1118.

The scandal produced an unexpected dynastic knot. William's son married Aenor of Châtellerault, a daughter of Dangereuse and her lawful husband, and from that marriage came Eleanor of Aquitaine, born around 1122 ^[1]. The duke who sang of love thus became grandfather to the most celebrated heiress of the Middle Ages, the future queen of both France and England, and through her an ancestor of the Plantagenet kings.

War filled much of his final decade. After losing his second grip on Toulouse, William turned south and joined his brother in law Alfonso I of Aragon, called the Battler, in campaigns against the Almoravids in Spain. In June 1120 he fought at the battle of Cutanda, near Daroca, where the Christian coalition won a crushing victory, and he took part in operations that consolidated the recent conquest of Zaragoza ^[2]. These Spanish expeditions restored some of the military reputation he had lost in Anatolia in 1101.

At home he faced a rebellion of his son. The younger William, resentful of his mother's treatment and allied with disaffected barons, rose against his father in the early 1120s before the two were reconciled ^[4]. The aging duke also mended some fences with the Church, and the sentence of excommunication was eventually lifted. His last datable song, the penitential piece beginning Pos de chantar, in which the poet says he will give up joy and entrust his lands and his young son to God, may belong to this period of retrenchment, though scholars have proposed earlier occasions for it ^[7].

William died on February 10, 1126, in Poitiers, aged fifty four, and was succeeded without dispute by William X ^[1]. He had ruled Aquitaine for forty years, longer than most kings of his era reigned, and he left the duchy intact despite crusade, rebellion, and two papal censures.

Any William IX, Duke of Aquitaine biography must reckon with a double inheritance, political and poetic. Politically, he kept a sprawling and fractious duchy together and passed it whole to his son. Within three decades of his death that inheritance, carried by Eleanor, would join first the French crown and then the Angevin empire of Henry II, making Aquitaine the hinge of western European politics for centuries ^[1].

The poetic legacy proved even larger. The troubadour art that begins, for us, with his eleven songs spread through the courts of southern France, into Spain and Italy, and northward through the trouvères of France and the Minnesänger of Germany ^[3]. The vocabulary of courtly love, the idea that desire could be examined, refined, and sung in the poet's own language, descends in a direct line from the Poitevin court. Dante and Petrarch inherited the tradition he opened, and modern lyric poetry in European languages still carries its imprint ^[7].

Historians continue to argue over the man himself. Was he a cynical libertine, as monastic chroniclers claimed, or a shrewd ruler whose irreverence masked calculation? Ruth Harvey and other scholars have shown how much of the colorful anecdote around him rests on hostile or late testimony, and they urge caution in separating the poet's comic persona from the duke's actual conduct ^[4]. Among the durable William IX, Duke of Aquitaine facts, this much is secure: he was the first named poet of a new European art, and his voice, boastful, funny, tender, and rueful by turns, is the oldest we can still hear from the troubadour world ^[8].
