Charibert II: Dagobert’s Half-Brother and the Kingdom of Aquitaine

p4

Dagobert I: The Last Great Merovingian King · EARLY MIDDLE AGES

When Chlothar II died in 629, his son Dagobert I inherited the main throne of the Frankish kingdom.
But he was not the only heir: his half-brother Charibert II, son of Queen Sichilde, also had dynastic rights.

To avoid war between the two princes, Dagobert accepted a political compromise: he granted Charibert a new kingdom in the south.

👑 Creating the kingdom of Aquitaine

Dagobert gave Charibert control of a kingdom of Aquitaine, centred on Toulouse.

This kingdom notably included:

  • Toulouse
  • Agen
  • Cahors
  • Périgueux
  • Saintes

It extended to the Pyrenees, also including Vasconia, where the ancestors of the Basques lived.

This decision calmed political tension while keeping Dagobert as the principal sovereign of the Regnum Francorum.

⚔️ Charibert against the Vascones

The new king of Aquitaine quickly faced local revolts.

The Vascones, mountain peoples settled at the foot of the Pyrenees, challenged Frankish authority. Charibert led campaigns to restore order.

With the help of local dukes and counts, he managed to stabilise Aquitaine and reaffirm Frankish authority in the southwest.

⚰️ An early death

Charibert II’s reign was very short.

In 632, he died suddenly, probably of illness. His young son Chilperic briefly succeeded him, but he too died soon after.

Some medieval chroniclers suggested this death may have been ordered by Dagobert, who wanted to recover Aquitaine. However, there is no firm proof.

👑 Aquitaine returns to the Frankish kingdom

After Charibert and his son died, Dagobert took direct control of Aquitaine again.

The Frankish kingdom was then almost completely reunified, as under his father Chlothar II.

This reunification marked the peak of Dagobert’s power and the high point of Merovingian monarchy.

🧠 Key takeaways

  • Charibert II is Dagobert I’s half-brother.
  • He becomes king of Aquitaine in 629 to avoid dynastic war.
  • He fights the Vascones and stabilises the region.
  • His death in 632 allows Dagobert to reunify the Frankish kingdom.
