629 CE

1. The Inheritance of Dagobert I and the Succession Dispute

Upon Chlothar II’s death, his eldest son, Dagobert I, assumes control of the core Frankish realms, including:
- Neustria (northern Frankish lands, including Paris)
- Burgundy (eastern and central Frankish territories)
His half-brother Charibert II, son of Chlothar’s second wife Sichilde, lays claim to Neustria, challenging Dagobert’s authority.

2. The Petition of Brodulf and Dagobert’s Ruthless Response

Brodulf, Sichilde’s brother, steps in as an advocate for his young nephew Charibert II, attempting to secure his share of the inheritance.
Brodulf petitions Dagobert to recognize Charibert’s claim, but rather than negotiating, Dagobert orders Brodulf’s assassination, eliminating a key supporter of his half-brother.
This ruthless act of political maneuvering ensures that Dagobert maintains full control over Neustria and Burgundy without opposition from Sichilde’s faction.

3. The Settlement: Charibert II Given Aquitaine

To prevent further conflict, Dagobert grants his younger brother Charibert II the newly formed sub-kingdom of Aquitaine, which had recently grown in importance.
This move serves multiple purposes:
- Pacifies Charibert, giving him an independent domain.
- Establishes Aquitaine as a semi-autonomous realm, reducing pressure on Dagobert’s main territories.
- Strengthens Frankish rule over southern Gaul, an area traditionally more Romanized and resistant to direct Frankish control.

4. The Final Victory of Chilperic’s Line

With Dagobert as the supreme ruler of the central Frankish lands and Charibert confined to Aquitaine, Chilperic’s descendants firmly secure their dynasty’s dominance.
The long civil war between the Merovingian factions, which had begun with Chilperic’s murder of Galswintha in 568, effectively ends with Dagobert’s triumph.
However, Charibert II’s death in 632 CE will later allow Dagobert to reabsorb Aquitaine, further consolidating his power.

Conclusion: Dagobert I’s Ruthless Consolidation of Power

Dagobert I ensures his supremacy through assassination, political strategy, and territorial concessions, emerging as the strongest Merovingian king since Clovis I. His decisive actions against Brodulf and Charibert II solidify his control, marking the final victory of Chilperic’s lineage in the Frankish succession wars. However, his granting of Aquitaine foreshadows the increasing fragmentation of the Frankish realm, setting a precedent for future regional autonomy and aristocratic power struggles.
