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 (843ā987); the expansion of royal control by the House of Capet (987ā1328), 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 (1328ā1589), including the protracted dynastic crisis against the House of Plantagenet and their Angevin Empire, culminating in the Hundred Years' War (1337ā1453) (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.
