The Angevin Empire (; ) describes the possessions of the House of Plantagenet during the 12th and 13th centuries, when they ruled over an area covering roughly half of France, all of England, and parts of Ireland and Wales, and had further influence over much of the remaining British Isles. 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 Plantagenet as Duke of Normandy and Count of Anjou (from which the Angevins derive their name). Henry married Eleanor of Aquitaine in 1152, becoming her royal consort, 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 House of Anjou 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, 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 Gascony in southern Aquitaine. This defeat set the scene for further conflicts between England and France, leading up to the Hundred Years' War. Origin of the term and its application The term Angevin Empire is a neologism defining the lands of the House of Plantagenet: Henry II and his sons Richard I and John. Another son, Geoffrey, ruled Brittany and established a separate line there. As far as historians know, there was no contemporary term for the region under Angevin control; however, descriptions such as "our kingdom and everything subject to our rule whatever it may be" were used. The term Angevin Empire was coined by Kate Norgate in her 1887 publication, England under the Angevin Kings. In France, the term (French for "Plantagenet area") is sometimes used to describe the fiefdoms the Plantagenets had acquired. The adoption of the Angevin Empire label marked a re-evaluation of the times, considering that both English and French influence spread throughout the dominion in the half century during which the union lasted.
