Charlemagne
The King Who United Europe
On Christmas Day in the year 800, in the basilica of Saint Peter in Rome, Pope Leo III placed a crown upon the head of a Frankish king and proclaimed him Emperor of the Romans. The man who knelt before the altar had spent thirty years at war — against the Saxons, the Lombards, the Avars, the Saracens — and had assembled the largest empire the West had seen since Rome itself collapsed. His name was Charles, King of the Franks. History would call him Charlemagne: Charles the Great. More than any other figure of the medieval world, he shaped the political, cultural, and religious map of Europe that endures to this day.
“Right action is better than knowledge; but in order to do what is right, we must know what is right.”
c. 742–814 AD
Born into the Carolingian dynasty as the son of Pepin the Short, the first Frankish king to be anointed by the Pope. Died at Aachen after a reign of over four decades, leaving an empire that stretched from the Atlantic to the Elbe, from the North Sea to southern Italy.
32 years
The longest and bloodiest of Charlemagne's campaigns — thirty-two years of warfare against the pagan Saxons of northern Germania, from 772 to 804. It ended only when Saxony was fully absorbed into the Frankish realm and its people forcibly baptised.

Charlemagne spoke Frankish and Latin fluently, understood Greek, and could read — though he never mastered writing. He reportedly kept a wax tablet under his pillow at night, practising letter-forms in his final years. He embodied the ideal of the scholar-king he promoted in others.
1M km²
At its peak, the Carolingian Empire covered roughly one million square kilometres — modern France, Belgium, the Netherlands, western Germany, Austria, Switzerland, and northern Italy. No western ruler had governed so vast a territory since the fall of Rome three centuries earlier.

Defining Events
The Saxon Wars
The defining campaign of Charlemagne's reign — thirty-two years of brutal warfare against the pagan Saxon tribes of northern Germania. The Saxons fought with the ferocity of men defending their gods, their land, and their way of life. Charlemagne responded with corresponding ruthlessness: in 782 at Verden, he ordered the massacre of 4,500 Saxon prisoners in a single day — the Blutgericht, or Blood Court. Yet the war was also a conquest of conversion: churches rose beside every fortification, and Charlemagne's capitularies made apostasy a capital offence. By 804, Saxony was Christian and Frankish — its people absorbed, its gods forgotten, its great warrior Widukind baptised and granted an estate.
The Imperial Coronation
On Christmas Day in the year 800, Pope Leo III placed a golden crown on Charlemagne's head in the basilica of Saint Peter in Rome and proclaimed him Imperator Romanorum — Emperor of the Romans. The crowd's acclamation shook the ancient walls. Charlemagne, according to Einhard his biographer, claimed he would never have entered the church that day had he known what the Pope intended — whether genuine surprise or political theatre, historians still debate. What is certain is that the coronation created a concept that would shape European politics for a thousand years: the idea that a Christian emperor, blessed by the Pope, stood as the rightful heir to Rome's authority in the West.
The Carolingian Renaissance
Charlemagne's most enduring achievement was not military but intellectual. He gathered the finest minds of Europe to his court at Aachen — Alcuin of York from England, Paul the Deacon from Italy, Theodulf from Spain — and set them to work preserving, copying, and teaching the classical heritage that the chaos of the early medieval period had nearly destroyed. Monasteries became scriptoria; a new, legible script — Carolingian minuscule — replaced the regional chaos of earlier hands and became the ancestor of modern Roman type. Schools opened across the empire. Charlemagne himself attended lectures, studied rhetoric, astronomy, and theology. The manuscripts copied by his monks survive as the earliest versions of texts by Virgil, Cicero, and Tacitus. Without the Carolingian Renaissance, much of classical antiquity would be lost.
Timeline
Born
Born, probably on April 2, to Pepin the Short — first of the Carolingian kings — and Bertrada of Laon. The exact year is disputed: sources suggest 742 or 747. He grew up at the Frankish court, receiving a practical education in horsemanship, hunting, and the art of war, supplemented in later life by a voracious self-education in Latin letters.
King of the Franks
On Pepin's death, the Frankish kingdom was divided equally between Charles and his younger brother Carloman — a Frankish custom that threatened to fracture everything their father had built. The brothers ruled uneasily side by side, their relationship strained by personal antipathy and competing ambitions. When Carloman died suddenly in December 771, Charles absorbed his lands immediately, over the protests of Carloman's wife and sons, who fled to the Lombard court in Italy.
Saxon Wars Begin
Charlemagne launched the first of what would become thirty-two years of warfare against the Saxon tribes east of the Rhine. The campaign began with the destruction of the Irminsul — the great sacred pillar of the Saxon gods — a deliberate act of religious desecration designed to demonstrate the powerlessness of the pagan world against the Christian king. The Saxons proved resilient. They would fight, submit, rebel, and fight again for three decades before the final incorporation of their territory into the Frankish realm.
Conquest of Lombardy
At the Pope's appeal, Charlemagne crossed the Alps and besieged the Lombard capital of Pavia. After a siege of nearly a year, the Lombard king Desiderius — whose daughter Charlemagne had divorced — surrendered. Charlemagne had himself crowned King of the Lombards and exiled Desiderius to a Frankish monastery. He then made the first of many visits to Rome, confirming and expanding the Papal States. The union of Frankish military power and papal spiritual authority that would define medieval Christendom was sealed.
Roncevaux Pass
Charlemagne led an expedition into Muslim-controlled Spain at the invitation of a rebellious Moorish governor. The campaign in the Ebro valley achieved little. On the withdrawal through the Pyrenees, the rearguard of his army — commanded by his nephew Roland, among others — was ambushed in the mountain pass of Roncevaux by Basque warriors and annihilated. Charlemagne lost some of his finest officers. The disaster became the seed of <em>La Chanson de Roland</em>, the founding epic of French literature, in which the Basques became Saracens and Roland became a legend.
Widukind Baptised
The great Saxon war leader Widukind, who had led resistance to Charlemagne for over a decade, submitted and accepted baptism — with Charlemagne himself standing as his godfather. It was the symbolic turning point of the Saxon Wars. Widukind was granted lands and treated honourably; his conversion was presented throughout the Christian world as proof of Charlemagne's divine mission. Saxony's resistance continued for another two decades, but without its most charismatic leader it never again posed an existential threat.
Emperor of the Romans
On Christmas Day in Saint Peter's Basilica, Rome, Pope Leo III — whom Charlemagne had recently restored to power after a violent attack by his enemies — crowned Charlemagne <em>Imperator Romanorum</em>. The acclamation of the Roman people followed. Einhard records that Charlemagne was displeased by the manner of the coronation, fearing Byzantine reaction. Regardless of his private feelings, the act transformed the political landscape of Europe: the Western Roman Empire, dormant since 476, was declared reborn in the person of a Frankish king.
Empire Building
The final decade of Charlemagne's reign was devoted to administration rather than conquest. He issued a comprehensive series of <em>capitularies</em> — written laws covering everything from Church reform to currency standards — and deployed <em>missi dominici</em> (royal envoys) in pairs across the empire to inspect local governance and report abuses directly to the emperor. He standardised weights and measures, reformed coinage, promoted literacy among the clergy, and corresponded with the Caliph of Baghdad, Harun al-Rashid, who sent him an elephant named Abul-Abbas as a diplomatic gift.
Death at Aachen
Charlemagne died on January 28, 814, at his beloved capital of Aachen, of pleurisy — an inflammation of the lungs — at the age of approximately seventy-two. He had already crowned his surviving son Louis the Pious as co-emperor the previous year. He was buried the same day in the Palatine Chapel he had built. Within a generation, his empire would be divided among his grandsons at the Treaty of Verdun in 843 — the partition that created the ancestors of modern France and Germany.
Key Figures
Alcuin of York
The greatest scholar of the Carolingian Renaissance, Alcuin was an English monk from York whom Charlemagne recruited to his court in 782 and never let go. He became head of the Palace School at Aachen, tutor to the royal family, and the emperor's most trusted intellectual companion — Charlemagne called him 'Albinus', and their correspondence reveals a friendship of genuine warmth and mutual respect. Alcuin revised the text of the Latin Bible, reformed the liturgy, established the curriculum of the <em>trivium</em> and <em>quadrivium</em> that would organise European education for centuries, and trained a generation of scholar-monks who carried Carolingian learning across the empire. He ended his days as abbot of Tours, surrounded by his books.
Pope Leo III
Leo III became Pope in 795, an outsider candidate who immediately sent Charlemagne the keys of Saint Peter's tomb and the banner of Rome — a symbolic gesture of submission that established the terms of their relationship. In 799, his enemies in Rome attacked him in the street, attempting to gouge out his eyes and cut out his tongue. He escaped and fled to Charlemagne's court, where the king investigated the accusations against him and ultimately cleared him. Leo returned to Rome under Frankish escort. On Christmas Day 800, he repaid the debt with a crown — and in doing so transformed both Charlemagne and the papacy. The coronation established the principle that popes could make and unmake emperors, a claim that would generate centuries of conflict between Rome and the rulers of Europe.
The Legacy of Charlemagne
Charlemagne's empire did not survive him intact. At the Treaty of Verdun in 843, his three grandsons divided his lands into three kingdoms — the ancestors of France, Germany, and Italy. But the idea of his empire proved far more durable than the empire itself. For a thousand years, European rulers would claim to rule the Holy Roman Empire in his name; Napoleon was crowned in deliberate imitation of his coronation; and the founders of the modern European Union placed his legacy at the heart of their project — the Charlemagne Prize, awarded annually in Aachen since 1950, honours those who serve the cause of European unity.
He was a man of contradictions: a warrior who ordered massacres and a patron who built schools; a king who could not write and an emperor who transformed literacy; a conqueror whose violence shaped a continent and a scholar whose libraries preserved what the violence of others had nearly destroyed. He is buried beneath the cathedral at Aachen, in a golden reliquary that pilgrims visited for centuries. Europe, in more ways than one, was built over his bones.
