Although in December 1154, Henry was generally recognised as the legitimate claimant to the throne, most notably by the English Church, his accession was fraught with perils. Among the Anglo-Norman aristocracy there were many who saw Henry as an outsider: an Angevin princeling, descended via his father, Count Geoffrey Plantagenet of Anjou, from a dynasty that had long been regarded as the principal rival on Normandy’s southern frontier. King Stephen had left a legitimate son, William Earl Warenne, still living in 1154, and Henry himself had two younger brothers who might well have disputed his claims to succeed to all his family’s lands and titles. Asked some years before to judge Henry’s chances of success, St Bernard of Clairvaux is said to have predicted of Henry that ‘from the Devil he came, and to the Devil he will surely go’.
Yet, from what contemporaries termed ‘the shipwreck’, and modern historians have described as ‘the anarchy’ of Stephen’s reign, Henry II was to emerge as one of England’s, indeed as one of Europe’s, greatest kings. The Plantagenet dynasty that he founded was to occupy the throne of England through to 1399 and the eighth successive generation. Henry himself came to rule over the most extensive collection of lands that had ever been gathered together under an English king – an empire in all but name, that stretched from the Cheviots to the Pyrenees, and from Dublin in the west to the frontiers of Flanders and Burgundy in the east.
In part this empire was the product of dynastic accident. From his mother, Matilda, daughter and sole surviving legitimate child of the last Anglo-Norman King, Henry inherited his claim to rule as king in England and as duke in Normandy. From his father, Geoffrey, he succeeded to rule over Anjou, Maine and the Touraine: the counties of the Loire valley that had previously blocked Anglo-Norman ambitions in the South. Rather than share these inherited spoils with his brothers, Henry seized everything for himself. William, his younger brother, was granted a rich but by no means royal estate. Geoffrey, the third brother, threatened rebellion but was bought off with a shortlived grant of the county of Nantes.
Henry, however, was far more than just a fortunate or crafty elder son. Through his own exertions he greatly expanded his family’s territorial claims. In 1152, two years before obtaining the throne of England, he had married Eleanor, heiress to the duchy of Aquitaine and only a few weeks earlier divorced from her previous husband, the Capetian King Louis VII. As effective ruler of Eleanor’s lands, Henry found himself in possession of a vast estate in south-western France, stretching from the Loire southwards through Poitou and Gascony to the frontiers of Spain. Henry’s marriage to Eleanor was regarded as scandalous even by his own courtiers. She was eleven years older than him and was rumoured to have enjoyed extra-marital affairs not only with her own uncle but with Henry’s father, Geoffrey Plantagenet. By temperament she was as fiery as Henry, and as determined to stake her own claims to rule. As a result, Henry’s domestic life was far from tranquil. From 1173 onwards, Eleanor was to be held under house arrest in England, whilst Henry, to judge by the bastard children that he fathered, had long enjoyed the favours of a series of mistresses. Even so, by his marriage, Henry laid the basis of the later claims made by England’s kings to rule over southern France: claims that were to unite Gascony to the English crown as late as the fifteenth century and which were to play a vital role in the history of Anglo-French relations throughout the Middle Ages and beyond.
