The son of King Louis VII and his third wife, Adela of Champagne, he was originally nicknamed 'God-given' because he was a first son and born late in his father's life. Philip was given the epithet "Augustus" by the chronicler Rigord for having extended the crown lands of France so remarkably.

The term Angevin Empire describes the possessions 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 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 as Duke of Normandy and Count of Anjou. 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 l'Aigle family was a Norman family that derived from the town of L'Aigle, on the southeastern borders of the Duchy of Normandy. They first appear during the rule of Duke Richard II of Normandy, in the early 11th century, and they would hold L'Aigle for the Norman Dukes and Kings of England until the first half of the 13th century, when with the fall of Normandy to the French crown the last of the line was forced to abandon the ancestral French lands, only to die in England a few years later without surviving English heirs. Their position on the borderlands, and near the headwaters of three rivers, the Risle, Iton and Avre, gave their small holding a special importance, as did a set of marriage connections that provided this relatively minor Norman noble family with a more elevated historical visibility. Having been neighbors and benefactors of the Abbey of Saint-Evroul, the family receive mostly favourable coverage in the 12th-century chronicle of Orderic Vitalis.
Rotrou III, called the Great, was the Count of Perche and Mortagne from 1099. He was the son of Geoffrey II, Count of Perche, and Beatrix de Ramerupt, daughter of Hilduin IV, Count of Montdidier. He was a notable Crusader and a participant in the Reconquista in eastern Spain, even ruling the city of Tudela in Navarre from 1123 to 1131. He is commonly credited with introducing Arabian horses to the Perche, giving rise to the Percheron breed. By his creation of a monastery at La Trappe in memory of his wife, Matilda, daughter of Henry I of England, in 1122 he also laid the foundations of the later Trappists.
The Angevin kings of England were Henry II and his sons, Richard I and John, who ruled England from 1154 to 1216. With ancestral lands in Anjou, they were related to the Norman kings of England through Matilda, the daughter of Henry I, and Henry II's mother. They were also related to the earlier Anglo-Saxon kings of England through Matilda's great-great-grandfather, Edmund Ironside. Their descendants, the main line of the House of Plantagenet, continued to rule England until 1485; some historians make no distinction between the Angevins and the Plantagenets, while others name John's son Henry III the first Plantagenet king.
