Duchy of Aquitaine (1154–1453)

Duchy of Aquitaine (1154–1453) The Duchy of Aquitaine (1154–1453) was a large and semi-autonomous territorial possession in southwestern France held by the Plantagenet kings of England from the accession of Henry II of England through the end of the Hundred Years' War. It encompassed historic provinces such as Gascogne, Guyenne, and Poitou and included major urban centers like Bordeaux, La Rochelle, and Bayonne. The duchy functioned as a transnational lordship linking the courts of London and Poitiers and was a focal point for dynastic rivalries between the Capetian dynasty and the House of Plantagenet.

Background and Formation

Aquitaine's medieval identity derived from the earlier Aquitaine and the ducal line of Eleanor of Aquitaine, whose marriages to Louis VII of France and later Henry II of England reshaped western European politics. The 1152 marriage of Eleanor of Aquitaine to Henry II of England transferred ducal rights into the Angevin realm, consolidating territories including Gascogne, Limousin, Saintonge, and Angoumois. The resulting Angevin Empire pitted Henry II and his sons—Richard I of England and John, King of England—against the Capetian kings such as Philip II of France and later Louis IX, producing recurring legal and military contests over fealty and suzerainty. Treaties and disputes like the Treaty of Paris (1259) and the Treaty of Brétigny emerged from this complex patrimonial genesis.

Governance and Administration

Plantagenet rule in Aquitaine combined feudal prerogatives with local customary law such as the coutume d'Aquitaine, and administrative practice centered on regional courts and seneschals. Key officials included the Seneschal of Aquitaine and the Bailiff who represented ducal authority in judicial and fiscal matters; municipal autonomy in cities like Bordeaux was buttressed by merchant corporations and consular institutions. The ducal household maintained ties to the English royal chancery and the Curia Regis, while diplomatic relations involved embassies to the Papal States and negotiations with Navarre and Aragon. Legal pluralism meant that Roman law influences circulated alongside Occitan customary norms, with appeals sometimes directed to the ducal court in Poitiers or to the English crown in Westminster.

Economy and Society

Aquitaine's economy was driven by viticulture around Bordeaux, salt production along the Atlantic coast, and maritime trade through ports such as La Rochelle and Bordeaux. The duchy's export trade in wine and salt linked merchants of Bordeaux to markets in England, Flanders, Hanseatic League ports, and Castile, fostering urban elites and merchant oligarchies. Rural society featured peasant holdings, seigneurial demesnes, and monastic landholding by institutions like Cluny and Cistercian abbeys, which shaped agrarian productivity. Social tensions appeared in urban revolts, tax disputes, and conflicts between local lords and communes—episodes reflected in chronicles by Froissart and administrative records preserved in the archives of Bordeaux and Poitiers.

Role in the Hundred Years' War

Aquitaine was a principal theater during the Hundred Years' War where dynastic claims of the House of Plantagenet and the House of Valois collided. Major campaigns and sieges affected the duchy: the seizure of Poitiers (1356) and the capture of Edward the Black Prince at the Battle of Poitiers underscored its strategic importance; later actions at La Rochelle and the naval engagement around Sluys influenced supply lines. The Treaty of Brétigny (1360) temporarily expanded English sovereignty in Aquitaine, while the resurgence of Charles VII of France and the leadership of commanders like Jean Bureau and the reforms associated with Étienne Marcel gradually eroded Plantagenet control. The Black Death and prolonged warfare depopulated districts and disrupted agrarian production, altering recruitment and fiscal capacity for both English Crown and French Crown forces.

Decline and Integration into France

From the mid-15th century, military reverses and political realignments hastened Aquitaine's transfer to French control. The decisive French victory at the Battle of Castillon (1453) effectively ended large-scale English territorial holdings on the continent, with subsequent administrations under Charles VII of France extending royal institutions and integrating provinces such as Guyenne and Gascogne into the Kingdom of France. Noble families like the Dukes of Burgundy and local magnates negotiated terms of surrender, while Bordeaux's surrender in 1453 concluded the Plantagenet presence. The transition involved assimilation of legal codes, incorporation of fiscal systems, and the redistribution of seigneurial rights, marking the end of the Angevin continental polity and the consolidation of Capetian-derived royal authority.
