The Division of Lotharingia: The End of a Unified Duchy (959)
By 959, Bruno the Great, the Duke of Lotharingia and Archbishop of Cologne, makes a critical administrative decision that permanently ends the unity of Lotharingia. As one of the last dukes of the whole region, Bruno appoints two local nobles, Frederick and Godfrey, as margraves, effectively splitting the duchy into Upper and Lower Lotharingia.
Background: Lotharingia’s Shifting Allegiances
- Originally part of Middle Francia, Lotharingia had long been contested between East and West Francia since the Treaty of Meerssen (870) and the Treaty of Ribemont (880).
- It had shifted from East Francia (Germany) to West Francia (France) and back again, remaining a hotly disputed territory.
- Under Bruno’s rule, Lotharingia was stabilized as part of the Holy Roman Empire, but its vast size and strategic importance made it difficult to govern as a single duchy.
The Division of Lotharingia (959)
To ensure more effective rule, Bruno appoints:
- Frederick I as Margrave of Upper Lotharingia, later recognized as Duke of Upper Lorraine.
- Godfrey I as Margrave of Lower Lotharingia, later known as Duke of Lower Lorraine.
This administrative division is meant to improve governance and military defense but ultimately results in:
- The permanent split of Lotharingia into two distinct duchies.
- A further weakening of centralized control, as regional lords gain more autonomy.
- Continued fragmentation, making Lotharingia a battleground for German, French, and local noble interestsin the following centuries.
Legacy: The Last Duke of a United Lotharingia
- Bruno is one of the last rulers to control all of Lotharingia as a single entity.
- His decision in 959 shapes the future of the region, ensuring that Upper and Lower Lorraine evolve as separate feudal entities.
- This fragmentation reinforces feudal decentralization, marking another step toward the eventual dissolution of the Carolingian world and the rise of independent regional powers.
With Bruno’s death in 965, the once-mighty Lotharingia is permanently divided, reflecting the broader breakdown of centralized authority in medieval Europe.
