A comprehensive journey through 72 years that reshaped Western civilization
Charlemagne, also known as Charles the Great (Karlus Magnus in Latin), was born near Liège in what is now Belgium. He was the eldest son of Pepin the Short, who would become the first Carolingian king of the Franks. His exact birth date is unknown, though historians estimate it was around 742 AD. His birthplace was likely the palace of Austrasia, one of the principal seats of Frankish royalty.
Young Charlemagne received instruction in the liberal arts,骑马 (horseback riding), and hunting—skills essential for a Frankish noble. He learned to read and write Latin, though his writing never became elegant. Einhard, his biographer, noted that Charlemagne studied grammar, rhetoric, and astronomy with such dedication that he often kept his tablets beneath his pillow for late-night study.
Pope Stephen II traveled to Francia to meet with Pepin the Short, marking the first time a pope crossed the Alps to seek alliance with a Frankish ruler. At Quierzy, the Pope baptized Charlemagne and his brother Carloman and anointed them both as "Roman patricians"—a sacred designation that would later prove crucial to Charlemagne's imperial ambitions. This ceremony established the church-state partnership that would define Charlemagne's reign.
Upon the death of Pepin the Short, Charlemagne and his brother Carloman jointly inherited the Frankish kingdom. Charlemagne received the larger portion—Austrasia, Neustria, and the southern regions—while Carloman controlled the interior territories including Burgundy and Provence. At Noyon, Charlemagne was crowned king by the Frankish clergy, beginning his legendary reign.
The sudden death of Carloman left Charlemagne as the sole ruler of the Frankish kingdom. Carloman's young son was set aside, and the late king's supporters were either won over or eliminated. This consolidation gave Charlemagne free rein to pursue his ambitions without domestic opposition. Einhard wrote that God had "delivered him from the hand of his brother."
Charlemagne first secured his southern frontier by crushing a revolt in Aquitaine, completing a campaign his father had begun. He then turned his attention to the northeast, where pagan Saxon tribes had long raided Frankish territories. In 772, he launched the first of what would become eighteen brutal campaigns against the Saxons—a war that would last over three decades and reshape the religious and political landscape of Germany.
The Saxon Wars were Charlemagne's longest and most brutal military campaign. The Germanic Saxon tribes, led by figures like Widukind, fiercely resisted Frankish expansion. Charlemagne responded with scorched-earth campaigns, mass executions (notably at Verden in 782, where 4,500 Saxons were beheaded), and forced baptisms. The war ended only when the Saxons accepted Christianity and Frankish overlordship. By 804, the last independent Saxon resistance had been crushed.
At the invitation of Pope Adrian I, Charlemagne crossed the Alps to defeat Desiderius, the Lombard king who threatened papal territories. After a siege of Pavia that lasted over a year, the city fell. Charlemagne took the title "King of the Lombards," adding northern Italy to his domains. This victory made him the most powerful ruler in Western Europe and cemented his alliance with the papacy.
Perhaps the most famous defeat of Charlemagne's career occurred in the Pyrenees when his rear guard, including the legendary Frankish knight Roland, was ambushed by Basque forces. The "Song of Roland," composed centuries later, immortalized this battle in medieval literature. Though a tactical defeat, it did not significantly impact Charlemagne's overall campaigns in Spain.
Charlemagne launched multiple campaigns into Spain, carving out a buffer zone called the "Spanish March" between Frankish territory and the Umayyad Caliphate. He established the Marca Hispanica—a frontier zone with a series of fortified counties that would eventually grow into modern Catalonia and Aragon.
The defining moment of Charlemagne's reign occurred in St. Peter's Basilica in Rome. As Charlemagne knelt in prayer, Pope Leo III placed a crown upon his head while the assembled crowd erupted in cheers: "To Charles, the most pious Augustus, crowned by God, the great and peace-giving Emperor of the Romans!" This coronation was both a culmination of decades of alliance with the papacy and a deliberate attempt to revive the Western Roman Empire that had collapsed nearly four centuries earlier.
Charlemagne annexed Bavaria, ending the rule of the Bavarian dukes who had maintained considerable independence. He then turned to the Avars, a nomadic people in the Danube basin who had amassed tremendous wealth through raiding. Frankish campaigns destroyed the Avar khanate, and the vast treasures—accumulated over generations—were transported to Charlemagne's palace at Aachen, reportedly requiring 15 wagons and several trips.
Charlemagne divided his empire among his three sons—Charles the Younger would receive Neustria and Austrasia; Pepin would govern Italy; and Louis would rule Aquitaine and the Spanish March. However, only Louis would survive him. When Charlemagne died, Louis the Pious inherited the entire empire, eventually passing it to his own sons, who would divide it into the kingdoms that would become France and Germany.
Charlemagne recruited scholars from across Europe, including the English monk Alcuin of York, who became his chief educator and reformer. The Palace School at Aachen became a center of learning where grammar, rhetoric, arithmetic, astronomy, and theology were taught. Alcuin developed new textbooks and standardized curricula that would influence European education for centuries. He also introduced the Carolingian minuscule script—a revolutionary writing style that improved readability and became the ancestor of modern lowercase letters.
Charlemagne issued a royal decree requiring all monasteries to establish schools where reading, writing, music, and computation would be taught. Priests were ordered to learn Latin and to explain the meaning of prayers and scripture to their congregations. This was a radical reform in an age when even many clergy were barely literate. The Admonitio Generalica laid the foundation for the preservation and transmission of classical knowledge.
Charlemagne ordered the establishment of scriptoria (copying centers) at monasteries throughout his empire. These scriptoria produced beautifully illuminated manuscripts, including the Gospels, Church Fathers, and classical Latin texts. The scriptorium at Tours, led by the monk Benedict of Nursia, became especially famous. Without the Carolingian Renaissance, many works of ancient Rome—including those of Virgil, Cicero, and Lucretius—might have been lost forever.
In his final years, Charlemagne suffered from declining health. An illness in 810 left him partially paralyzed on his right side. He grew frail and could no longer ride horses, instead taking carriage rides through his estates. He began to withdraw from active governance, delegating more responsibilities to his son Louis. His final public appearance was at the Easter celebration of 813, when he crowned his son Louis as co-emperor in a ceremony that deliberately excluded papal involvement.
Charlemagne died at the age of approximately 72 in his palace at Aachen. According to Einhard, his physician prescribed a strict diet, but Charlemagne ignored it, preferring to eat roasted meat—an indulgence that proved fatal. He was buried in the Palatine Chapel at Aachen, which he had built as a replica of San Vitale in Ravenna. His death marked the end of an era and the beginning of the slow fragmentation of his empire.
Charlemagne's empire, though short-lived in its unified form, laid the foundations for what would become modern Europe. The territories he conquered and Christianized would form the core of Western Christendom. His concept of a unified Christian Europe—where religious and political authority were intertwined—persisted for over a millennium and continues to influence European identity and institutions to this day.
When Charlemagne's grandsons divided his empire through the Treaty of Verdun in 843, they created the nuclei of what would become France and Germany. The artificial borders of these new kingdoms, drawn by political convenience rather than ethnic or linguistic lines, would shape European conflicts for the next thousand years—including the world wars of the 20th century.
The manuscript tradition that Charlemagne championed preserved Latin literature, Christian theology, and ancient philosophy through the turbulent centuries that followed. Without the Carolingian Renaissance, the Renaissance of the 15th century would have lacked much of its source material. The Carolingian minuscule script also directly evolved into the lowercase letters we use today.
Since 1950, the Charlemagne Prize (Karlspreis) has been awarded annually to individuals who contributed to European unity. Recipients have included Winston Churchill, Konrad Adenauer, and Jean Monnet. The award recognizes that Charlemagne's vision of a unified Christian Europe, however imperfectly realized, established a precedent for the modern European Union.
