England under the Angevin Kings, Volumes I and II

The war, later known as the Anarchy, reached its turning point on 2 February 1141, when Stephen’s forces were defeated at the Battle of Lincoln, and the king himself was captured. Matilda seemed poised to claim the throne, but her arrogant behavior alienated key allies, including her half-brother Bishop Henry of Blois, who switched sides to support Stephen. By late 1142, Stephen had trapped Matilda inside Oxford Castle, and by the winter of 1142–43, her brother Robert of Gloucester was forced to abandon his campaign in Normandy to rescue her. During these 19 years of civil war, every secular institution of English government was destroyed, but the Church emerged as the only functioning national body, as Norgate famously notes, it “outrode the storm.” The Cistercian order, directed by St. Bernard of Clairvaux, gained widespread influence by promoting moral reform amid the chaos, while the rival claims of Henry of Winchester (Stephen’s brother and the pope’s legate) and Theobald of Canterbury (Matilda’s supporter) shaped the era’s ecclesiastical politics until Theobald’s reconciliation with Stephen after his return from exile.

The war ground to a stalemate by the early 1150s, as Stephen failed to dislodge the baronial castles that defied his authority, and a revolt by Ralf of Chester further weakened his position. In May 1149, Henry Fitz-Empress, the teenage son of Geoffrey and Matilda, landed in England to rally support for his mother’s claim, his cosmopolitan heritage—his father was the son of an Angevin count and a Cenomannian countess, his mother the daughter of Henry I of England (a Norman father and Flemish mother) and Matilda of Scotland (a Scottish Celt and West-Saxon queen)—making him a unifying figure for rival factions. By 1150, Stephen faced pressure from the disputed election of Henry Murdac as Archbishop of York, a Matilda loyalist, and King Louis VII of France attempted to mediate the conflict, with St. Bernard of Clairvaux pleading for peace. The Treaty of Wallingford in 1153 recognized Henry Fitz-Empress as Stephen’s heir, and when Stephen died the following year, Henry was crowned at Westminster on Christmas Day 1154, a moment Norgate ranks as nearly as significant as the Norman Conquest of 1066: for the first time since 1066, a king acceded without a rival, commanding the unanimous support of every rank in the realm to restore order after the anarchy.

Henry II’s reign marked the apex of Angevin power. He inherited not just England, but a vast continental dominion stretching from the Scottish border to the Pyrenees, encompassing Normandy, Anjou, Aquitaine, Brittany, and more—larger than any English ruler’s territories since Cnut, but unlike Cnut’s detached northern empire, a contiguous transcontinental realm. In 1156, his youngest brother Geoffrey received the city of Nantes from its citizens, bringing Brittany under Angevin control, while Henry’s 1159 war with Raymond V of Toulouse and ongoing tensions with Louis VII of France over the Norman Vexin set the stage for future conflict with the rising Capetian monarchy. Domestically, Henry set out to restore his grandfather Henry I’s administrative model, with the justiciar Roger of Salisbury’s system as his template, pushing through sweeping legal reforms that laid the foundation for English common law, including the Assize of Clarendon in 1166, which established new criminal procedure rules, and the Assize of Arms in 1181, which revived the ancient fyrd system of universal military obligation for free men.

The central conflict of Henry’s reign was his struggle with Thomas Becket, whom he had appointed Archbishop of Canterbury in 1162 hoping to control the Church. Norgate pushes back against later narratives that frame Becket’s transformation from opulent royal chancellor to ascetic church champion as a sudden, miraculous reversal, arguing that his piety was evident even in his earlier role. Becket, however, quickly became a staunch defender of ecclesiastical independence, leading to a series of clashes over clerical immunity and royal custom. The Council of Clarendon in January 1164 attempted to force Becket to accept the Constitutions of Clarendon, which limited church privileges, but he refused, and was found guilty of contempt at the Council of Northampton in autumn 1164, fleeing into exile in France. The dispute quickly became a matter of European diplomacy, drawing in Louis VII and the papacy, and Becket gained widespread sympathy across Christendom. Henry’s apparent outburst—asking why no one would “rid me of this turbulent priest”—led four knights to murder Becket in Canterbury Cathedral on 29 December 1170. The martyrdom shocked Europe, Becket was canonized in 1173, and Henry performed public penance at his shrine in 1174, reconciling with the Church.

In the meantime, Henry turned his attention to expanding his empire, launching the first English invasion of Ireland in 1171 to assert control over the Anglo-Norman adventurers who had begun conquering the island after Dermot MacMurrough, king of Leinster, appealed for help against his rivals in 1166. The invasion brought Ireland under the English crown, and Henry’s forces defeated a combined Norse-Gaelic fleet that summer to secure his authority.

The Great Rebellion of 1173–1174, which united Henry’s three surviving sons (the Young King Henry, Richard, and Geoffrey), the English baronage, the Scottish crown, and the Count of Flanders against him, tested the strength of his administration but ultimately ended in his triumph. While Henry fought on the continent, his representatives in England repelled a Scottish invasion, defeated Flemish reinforcements, and crushed the baronial revolt, leaving Henry more firmly in control than ever. By the late 1170s, his empire was the most powerful in Western Christendom, stretching from Ireland to the Pyrenees.

But family tensions soon eroded his authority. The Young King Henry, crowned as co-ruler in a failed constitutional experiment, died suddenly in June 1183 while besieging his father’s ally, leaving Richard as the eldest surviving son. Rivalry between Henry II, Richard, and Geoffrey (who died in 1186) escalated, and Philip Augustus of France exploited these divisions, allying with Richard against his father. By summer 1188, open conflict had broken out in Aquitaine, and Philip began seizing Angevin territories. In just three weeks in summer 1189, Henry lost his birthplace, his continental heartland, and his authority, dying in humiliation at Chinon on 6 July 1189, as Richard and Philip closed in on him. His death, recorded in vivid contemporary chronicles, marked the end of the greatest Angevin reign.
