Duchy of Aquitaine in the context of "Salian Franks"

The Hundred Years' War (French: Guerre de Cent Ans; 1337–1453) was a conflict between the kingdoms of England and France and a civil war in France during the Late Middle Ages. It emerged from feudal disputes over the Duchy of Aquitaine and was triggered by a claim to the French throne made by Edward III of England. The war grew into a broader military, economic, and political struggle involving factions from across Western Europe, fuelled by emerging nationalism on both sides. The periodisation of the war typically charts it as taking place over 116 years. However, it was an intermittent conflict which was frequently interrupted by external factors, such as the Black Death, and several years of truces.

The Hundred Years' War was a significant conflict in the Middle Ages. During the war, five generations of kings from two rival dynasties fought for the throne of France, then the wealthiest and most populous kingdom in Western Europe. The war had a lasting effect on European history: both sides produced innovations in military technology and tactics, including professional standing armies and artillery, that permanently changed European warfare. Chivalry reached its height during the conflict and subsequently declined. Stronger national identities took root in both kingdoms, which became more centralized and gradually emerged as global powers.

The first written records for the history of France appeared in the Iron Age. What is now France made up the bulk of the region known to the Romans as Gaul. Greek writers noted the presence of three main ethno-linguistic groups in the area: the Gauls, Aquitani and Belgae. Over the first millennium BC the Greeks, Romans and Carthaginians established colonies on the Mediterranean coast and offshore islands. The Roman Republic annexed southern Gaul in the late 2nd century BC, and legions under Julius Caesar conquered the rest of Gaul in the Gallic Wars of 58–51 BC. A Gallo-Roman culture emerged, and Gaul was increasingly integrated into the Roman Empire. In the later stages of the empire, Gaul was subject to barbarian raids and migration. The Frankish king Clovis I united most of Gaul in the late 5th century. Frankish power reached its fullest extent under Charlemagne. The medieval Kingdom of France emerged from the western part of Charlemagne's Carolingian Empire, known as West Francia, and achieved increasing prominence under the rule of the House of Capet, founded in 987.

A succession crisis in 1328 led to the Hundred Years' War between the House of Valois and the House of Plantagenet. The war began in 1337 following Philip VI's attempt to seize the Duchy of Aquitaine from its hereditary holder Edward III of England, the Plantagenet claimant to the French throne. A notable figure of the war was Joan of Arc, a French peasant girl who led forces against the English, establishing herself as a national heroine. The war ended with a Valois victory in 1453, strengthening French nationalism and increasing the power and reach of the French monarchy. During the Ancien Régime over the next centuries, France transformed into a centralized absolute monarchy through the Renaissance and Reformation. At the height of the French Wars of Religion, France became embroiled in another succession crisis, as the last Valois king, Henry III, fought against factions of the House of Bourbon and House of Guise. Henry, the Bourbon King of Navarre, won and established the Bourbon dynasty. A burgeoning worldwide colonial empire was established in the 16th century.

The duke of Aquitaine (Occitan: Duc d'Aquitània, French: Duc d'Aquitaine, IPA: [dyk dakitɛn]) 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. As a consequence, male-preference primogeniture was the practiced succession law for the nobility.

The Duchy of Gascony or Duchy of Vasconia was an ethnic Basque duchy located in present-day southwestern France and northeastern Spain, an area encompassing the modern region of Gascony. The Duchy of Gascony, then known as Vasconia, was originally a Frankish march formed to hold sway over the Basques. However, the duchy went through different periods, from its early years with its distinctively Basque element to the merger in personal union with the Duchy of Aquitaine to the later period as a dependency of the Plantagenet kings of England.

Gascony was under continuous English rule for approximately 300 years, from 1152 to 1453. Charles VII of France reconquered the territory as a final act of the Hundred Years' War and the northern part of the territory was annexed by the Kingdom of France in 1453. The corresponding portion within the Iberian Peninsula became the Kingdom of Navarre.

Henry II ( (1133-March-05) (1189-July-06)5 March 1133 – 6 July 1189) was King of England from 1154 until his death in 1189. During his reign he controlled England, substantial parts of Wales and Ireland, and much of France (including Normandy, Anjou, and Aquitaine), an area that was later called the Angevin Empire, and also held power over Scotland for a time and the Duchy of Brittany.

Henry was the eldest son of Geoffrey Plantagenet, Count of Anjou, and Matilda, daughter of Henry I of England. By the age of fourteen, he became politically and militarily involved in his mother's efforts to claim the English throne, at that time held by her cousin Stephen of Blois. Henry's father made him Duke of Normandy in 1150, and upon his father's death in 1151, Henry inherited Anjou, Maine and Touraine. His marriage to Eleanor of Aquitaine brought him control of the Duchy of Aquitaine. Thus, he controlled most of France. Henry's military expedition to England in 1153 resulted in King Stephen agreeing, by the Treaty of Wallingford, to leave England to Henry; he inherited the kingdom at Stephen's death a year later.

The Angevin Empire (/ˈændʒɪvɪn/; French: Empire Plantagenêt) was the collection of territories held by the House of Plantagenet during the 12th and 13th centuries, when they ruled over an area covering roughly all of present-day England, half of France, and parts of Ireland and Wales, and claiming overlordship and some influence over the remaining parts of Wales, Scotland and Ireland. It may be described as an early example of a composite monarchy. The empire was established by Henry II of England, who succeeded his father Geoffrey as duke of Normandy and count of Anjou (from the latter of which the term Angevin is derived). Henry married Eleanor of Aquitaine in 1152, acquiring the Duchy of Aquitaine, and inherited his mother Empress Matilda's claim to the English throne, succeeding his rival Stephen in 1154. Although their title of highest rank came from the Kingdom of England, the Plantagenets held court primarily on the continent at Angers in Anjou and at Chinon in Touraine.

The influence and power of the Angevin kings of England brought them into conflict with the kings of France of the House of Capet, to whom they also owed feudal homage for their French possessions, bringing in a period of rivalry between the dynasties. Despite the extent of Angevin rule, Henry's son King John was defeated in the Anglo-French War (1213–1214) by Philip II of France following the Battle of Bouvines. John lost control of most of his continental possessions, apart from Guyenne and Gascony in southern Aquitaine. This defeat set the scene for further conflicts between England and France, leading up to the Hundred Years' War (1337–1453), in which the Plantagenets re-established dominion over much of western, central, and northern France before losing their possessions again, this time permanently.

The Council of Clermont was a mixed synod of ecclesiastics and laymen of the Catholic Church, called by Pope Urban II and held from 17 to 27 November 1095 at Clermont, Auvergne, at the time part of the Duchy of Aquitaine.

While the council is known today primarily for the speech Pope Urban gave on the final day, it was primarily a synod focused on implementing the Cluniac reforms, enacting decrees and settling local and regional issues. This also included the extension of the excommunication of Philip I of France for his adulterous remarriage to Bertrade of Montfort and a declaration of renewal of the Truce of God, an attempt on the part of the church to reduce feuding among Frankish nobles.

During the Middle Ages, the Kingdom of France was a decentralised, feudal monarchy. In Brittany, Normandy, Lorraine, Provence, East Burgundy and Catalonia (the latter now a part of Spain), as well as Aquitaine, the authority of the French king was barely felt. France in the Middle Ages (roughly, from the 10th century to the middle of the 15th century) was marked by the fragmentation of the Carolingian Empire and West Francia (843–987); the expansion of royal control by the House of Capet (987–1328), including their struggles with the virtually independent principalities (duchies and counties, such as the Norman and Angevin regions), and the creation and extension of administrative and state control (notably under Philip II Augustus and Louis IX) in the 13th century; and the rise of the House of Valois (1328–1589), including the protracted dynastic crisis against the House of Plantagenet and their Angevin Empire, culminating in the Hundred Years' War (1337–1453) (compounded by the catastrophic Black Death in 1348), which laid the seeds for a more centralised and expanded state in the early modern period and the creation of a sense of French identity.

Up to the 12th century, the territory experienced an elaboration and extension of the seigneurial economic system (including the attachment of peasants to the land through serfdom); the extension of the feudal system of political rights and obligations between lords and vassals; the so-called "feudal revolution" of the 11th century during which ever smaller lords took control of local lands in many regions; and the appropriation by regional/local seigneurs of various administrative, fiscal and judicial rights for themselves. From the 13th century on, the state slowly regained control of a number of these lost powers. The crises of the 13th and 14th centuries led to the convening of an advisory assembly, the Estates General, and also to an effective end to serfdom. During the 70-year reign of Louis XIV, absolutist policies from Paris tightly constrained the regional nobility, centralising political power at Versailles.

The Aquitani were a tribe that lived in the region between the Pyrenees, the Atlantic Ocean, and the Garonne, in present-day southwestern France in the 1st century BC. The Romans dubbed this region Gallia Aquitania. Classical authors such as Julius Caesar and Strabo clearly distinguish the Aquitani from the other peoples of Gaul, and note their similarity to others in the Iberian Peninsula.

Their old language, the Aquitanian language, was a precursor of the Basque language and the substrate for the Gascon language (one of the Romance languages) spoken in Gascony. Between the 1st century and the 13th century, the Aquitani gradually adopted the Gascon language while part of the Roman Empire, then the Duchy of Gascony and the Duchy of Aquitaine.
