800: Imperial Coronation and the Idea of Empire
p4Charlemagne: Inherit, Conquer, Scale Up (768–814) · EARLY MIDDLE AGES
On 25 December 800, Charlemagne is crowned emperor in Rome. Whatever the exact motivations and balance of forces, the event changes political language: the West is no longer only a set of kingdoms — it thinks again with an imperial reference.
🎄 The Christmas ceremony
That day, Pope Leo III crowns Charlemagne in Rome. A famous representation (the mosaic of St John Lateran) shows Leo III and Charlemagne kneeling at Saint Peter’s feet: he gives distinct symbols (keys and banner), suggesting a distribution of powers from Rome.
According to Einhard, Charlemagne would have been displeased by the ritual order: the crown placed on his head as he prayed, followed by acclamation and prostration. The detail matters: the gesture can be read as claiming that the pope “makes” the emperor.
👑 More than a title
The imperial coronation serves to:
- give Carolingian power a higher status
- inscribe Charlemagne in symbolic continuity with the Roman Empire
- offer the West a figure of unity, at least ideologically
⚖️ A delicate balance
The new title reshapes relationships:
- with Rome (alliance and reciprocal dependencies)
- with Byzantium (competing legitimacies)
- with Frankish elites (a new staging of power)
🧭 Byzantine reaction and recognition (801–813)
The Eastern Empire initially refuses to recognise the coronation, perceived as a usurpation. Charlemagne’s advisers argue the title is “vacant” because Constantinople is ruled by Empress Irene, and even consider a rapprochement.
The situation is resolved gradually through diplomacy: the Peace of Aachen (812) brings a cautiously formulated recognition; recognition becomes clearer in 813.
👑 813: the example of Louis the Pious
In 813, Charlemagne changes the ritual for his son Louis: the crown is placed on the altar and Louis crowns himself. The gesture aims to reduce the idea that Empire depends on a coronation “granted” by the pope.
🧠 Key takeaways
- 800 is a major symbolic turning point.
- The Carolingian empire is a political, religious, and cultural construction.
- Charlemagne becomes a model for centuries to come.
