Henry II of England in the context of "Eleanor of Aquitaine"

Richard I (8 September 1157 – 6 April 1199), known as Richard the Lionheart or Richard Cœur de Lion (Old Norman French: Quor de Lion) because of his reputation as a great military leader and warrior, was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine, and Gascony; Lord of Cyprus; Count of Poitiers, Anjou, Maine, and Nantes; and was overlord of Brittany at various times during the same period. He was the third of five sons of Henry II of England and Eleanor of Aquitaine and was therefore not expected to become king, but his two elder brothers predeceased their father.

By the age of 16, Richard had taken command of his own army, putting down rebellions in Poitou against his father. Richard was an important Christian commander during the Third Crusade, leading the campaign after the departure of Philip II of France. Despite achieving several victories against his Muslim counterpart, Saladin, he was ultimately forced to end his campaign without retaking Jerusalem.

John (24 December 1166 – 19 October 1216) was King of England from 1199 until his death in 1216. He lost the Duchy of Normandy and most of his other French lands to King Philip II of France, resulting in the collapse of the Angevin Empire and contributing to the subsequent growth in power of the French Capetian dynasty during the 13th century. The baronial revolt at the end of John's reign led to the sealing of Magna Carta, a document considered a foundational milestone in English and later British constitutional history.

John was the youngest son of King Henry II of England and Duchess Eleanor of Aquitaine. He was nicknamed John Lackland (Norman: Jean sans Terre, lit. 'John without land') because, as a younger son, he was not expected to inherit significant lands. He became Henry's favourite child following the failed revolt of 1173–1174 by his brothers Henry the Young King, Richard, and Geoffrey against their father. John was appointed Lord of Ireland in 1177 and given lands in England and on the continent. During the reign of his brother Richard I, he unsuccessfully attempted a rebellion against Richard's royal administrators while the King was participating in the Third Crusade, but he was proclaimed king after Richard died in 1199. He came to an agreement with Philip II of France to recognise John's possession of the continental Angevin lands at the peace treaty of Le Goulet in 1200.

The University of Oxford is a collegiate research university in Oxford, England. There is evidence of teaching as early as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation. It grew rapidly from 1167, when Henry II prohibited English students from attending the University of Paris. After escalating conflict between students and the Oxford townspeople, some Oxford academics fled northeast to Cambridge, where they established the University of Cambridge in 1209. The two universities share many common features and are jointly referred to as Oxbridge.

The University of Oxford is made up of 43 colleges. Formally, only 36 of these are called colleges (independent bodies) while 4 are permanent private halls (owned by a larger religious organisation), and 3 are societies (controlled directly by the University). and a range of academic departments that are organised into four divisions. Colleges control their own membership and activities. Typically social life for students is centred around fellow college members. All students are members of a college. Oxford does not have a main campus. Its buildings and facilities are scattered throughout the city centre and around the town. Undergraduate teaching at the university consists of lectures, small-group tutorials at the colleges and halls, seminars, laboratory work and tutorials provided by the central university faculties and departments. Postgraduate teaching is provided in a predominantly centralised fashion.

The counts of Nantes were originally the Frankish rulers of the Nantais under the Carolingians and eventually a capital city of the Duchy of Brittany. Their county served as a march against the Bretons of the Vannetais. Carolingian rulers would sometimes attack Brittany through the region of the Vannetais, making Nantes a strategic asset. In the mid-ninth century, the county finally fell to the Bretons and the title became a subsidiary title of the Breton rulers. The control of the title by the Breton dukes figured prominently in the history of the duchy. The County of Nantes was given to Hoel, a disinherited son of a duke. He lost the countship due to a popular uprising. That uprising presented an opportunity for King Henry II of England to attack the Breton duke. In the treaty ending their conflicts, the Breton duke awarded the county to Henry II.

The House of Wessex, also known as the House of Cerdic, the House of the West Saxons, the House of the Gewisse, the Cerdicings and the West Saxon dynasty, refers to the family, traditionally founded by Cerdic of the Gewisse, that ruled Wessex in Southern England from the early 6th century. The house became dominant in southern England after the accession of King Ecgberht in 802. Alfred the Great saved England from Viking conquest in the late ninth century and his grandson Æthelstan became first king of England in 927. The disastrous reign of Æthelred the Unready ended in Danish conquest in 1014. Æthelred and his son Edmund Ironside attempted to resist the Vikings in 1016, but after their deaths the Danish Cnut the Great and his sons ruled until 1042. The House of Wessex then briefly regained power under Æthelred's son Edward the Confessor, but lost it after the Confessor's reign, with the Norman Conquest in 1066. All monarchs of England (and subsequently Great Britain) since William II have been descended from the House of Wessex through William the Conqueror's wife Matilda of Flanders, who was a descendant of Alfred the Great through his daughter Ælfthryth. All English and later British monarchs since Henry II are descended from the English kings of the House of Wessex through Henry I's wife, Matilda of Scotland, daughter of Margaret of Wessex, a great-granddaughter of Edmund Ironside.

The Duchy of Normandy grew out of the 911 Treaty of Saint-Clair-sur-Epte between King Charles III of West Francia and the Viking leader Rollo. The duchy was named for its inhabitants, the Normans.

From 1066 until 1204, as a result of the Norman Conquest of England, the dukes of Normandy were usually also kings of England, the only exceptions being Dukes Robert Curthose (1087–1106), Geoffrey Plantagenet (1144–1150), and Henry II (1150–1152), who became king of England in 1154.

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.
