Dagobert I

Upon the death of his father Chlothar II, Dagobert I inherited the entire Frankish realm. He became the sole king, ruling over Neustria, Austrasia, and Burgundy, marking the last time a Merovingian king held undisputed authority over all Franks.

Dagobert I was a major patron of the arts, commissioning goldsmiths and artisans. He richly endowed the Basilica of Saint-Denis, where he was later buried, and ordered the creation of the 'Throne of Dagobert,' a bronze folding chair that became a symbol of Frankish kingship.

Dagobert I led a campaign against the Slavic Wends under King Samo. The Frankish army was defeated at the Battle of Wogastisburg, a rare military setback for Dagobert. This defeat weakened Frankish influence in the east and emboldened Slavic tribes.

Before his death, Dagobert I divided the Frankish kingdom between his young sons: Sigebert III received Austrasia, and Clovis II received Neustria and Burgundy. This division weakened the Merovingian dynasty and paved the way for the rise of the mayors of the palace.
