The duke of Aquitaine (, , ) was the ruler of the medieval region of Aquitaine (not to be confused with modern-day Aquitaine) under the supremacy of Frankish, English, and later French kings.

As successor states of the Visigothic Kingdom (418–721), Aquitania (Aquitaine) and Languedoc (Toulouse) inherited both Visigothic law and Roman Law, which together allowed women more rights than their contemporaries would enjoy until the 20th century. Particularly under the Liber Judiciorum as codified in 642/643 and expanded by the Code of Recceswinth in 653, women could inherit land and titles and manage their holdings independently from their husbands or male relations, dispose of their property in legal wills if they had no heirs, represent themselves and bear witness in court from the age of 14, and arrange for their own marriages after the age of 20.Klapisch-Zuber, Christiane; A History of Women: Book II Silences of the Middle Ages, The Belknap Press of Harvard University Press, Cambridge, Massachusetts, London, England. 1992, 2000 (5th printing). Chapter 6, "Women in the Fifth to the Tenth Century" by Suzanne Fonay Wemple, pg 74. According to Wemple, Visigothic women of Spain and the Aquitaine could inherit land and title and manage it independently of their husbands, and dispose of it as they saw fit if they had no heirs, and represent themselves in court, appear as witnesses (by the age of 14), and arrange their own marriages by the age of twenty As a consequence, male-preference primogeniture was the practiced succession law for the nobility.

Coronation

The Merovingian kings and dukes of Aquitaine used Toulouse as their capital. The Carolingian kings used different capitals situated farther north. In 765, Pepin the Short bestowed the captured golden banner of the Aquitainian duke, Waiffre, on the Abbey of Saint Martial in Limoges. Pepin I of Aquitaine was buried in Poitiers. Charles the Child was crowned at Limoges and buried at Bourges. When Aquitaine briefly asserted its independence after the death of Charles the Fat, it was Ranulf II of Poitou who took the royal title. In the late tenth century, Louis the Indolent was crowned at Brioude.

The Aquitainian ducal coronation procedure is preserved in a late twelfth-century ordo (formula) from Saint-Étienne in Limoges, based on an earlier Romano-German ordo. In the early thirteenth century a commentary was added to this ordo, which emphasised Limoges as the capital of Aquitaine. The ordo indicated that the duke received a silk mantle, coronet, banner, sword, spurs, and the ring of Saint Valerie.

Direct rule of Carolingian kings

Restored dukes of Aquitaine under Frankish kings The Carolingian kings again appointed Dukes of Aquitaine, first in 852, and again since 866. Later, this duchy was also called Guyenne.

William X the Saint (1127–1137), son of William IX, also Count of Poitiers and Duke of Gascony. Eleanor of Aquitaine (1137–1204), daughter of William X, also Countess of Poitiers and Duchess of Gascony, married the kings of France and England in succession. Louis the Younger (1137–1152), also King of France, duke in right of his wife.

From 1152, the Duchy of Aquitaine was held by the Plantagenets, who also ruled England as independent monarchs and held other territories in France by separate inheritance (see Plantagenet Empire). The Plantagenets were often more powerful than the kings of France, and their reluctance to do homage to the kings of France for their lands in France was one of the major sources of conflict in medieval Western Europe.

Plantagenet rulers of Aquitaine In 1337, King Philip VI of France reclaimed the fief of Aquitaine from Edward III, King of England. Edward in turn claimed the title of King of France, by right of his descent from his maternal grandfather King Philip IV of France. This triggered the Hundred Years' War, in which both the Plantagenets and the House of Valois claimed supremacy over Aquitaine.

Lord of Aquitaine (1360–1369) In 1360, both sides signed the Treaty of Brétigny, in which Edward renounced the French crown but remained sovereign Lord of Aquitaine (rather than merely duke). However, when the treaty was broken in 1369, both these English claims and the war resumed.

On 6 October 1372, Prince Edward (who had returned to England the previous year) resigned the Principality of Aquitaine and Gascony, stating that the revenues he earned from Aquitaine were no longer sufficient to cover his expenses. cites Rot. Parl. ii. 310; Hallam, Const Hist, iii. 47. Thus, King Edward III, his father, resumed his title as Duke of Aquitaine.
