The site was never unoccupied until Théodebert, future king of Austrasia left the castle to crown himself, accompanied by Deoteria, Countess of Cabrières.
Saint Agericus, also called Airy, Algeric, or Aguy (c.521 in Verdun (possibly Harville), France - 588), was the tenth Bishop of Verdun, and an advisor to King Childebert II of Austrasia.
In 716, the Battle of Amblève, between Charles Martel with the Austrasians on one side and the joined forces of the Frisians and Neustrians under Ragenfrid and Chilperic II on the other side, was the first victory for Charles Martel.
When Sigebert I of Austrasia died in 575, Chilperic sent Desiderius to invade his kingdom, but Guntram of Burgundy sent the patrician Mummolus against him and Desiderius was defeated and forced to retreat, leaving Austrasia to Sigebert's son Childebert II.
He was a relative of Parthenius who had served the Ostrogoths and was to become one of Theodoric of Austrasia's key civil officials.
When Sigebert was assassinated later that year (575), Chilperic invaded the kingdom, but Guntram sent his general Mummolus (always Guntrams main weapon, for he was the greatest general in Gaul at the time) to remove him and Mummolus defeated Chilperic's general Desiderius and the Neustrian's forces retreated from Austrasia.
The Marca Hispanica resulted from the expansion south of the Frankish realm from their heartland in Neustria and Austrasia starting with Charles Martel in 732 and after various decades fighting between the Franks and Muslims (Moors) in the Iberian Peninsula.
In 613, several leading magnates of Austrasia and Burgundy abandoned Brunhilda, the great-grandmother and regent of their king, Sigebert II, and turned to Chlothar II of Neustria for support, promising not to rise in defense of the queen-regent and recognizing Chlothar as rightful regent and guardian of the young king.
Racho holds a tenuous place in authentic history as the predecessor in the diocese of Autun of Leodegar, a fully historical figure who was the great opponent of Ebroin— the mayor of the Palace of Neustria— and the leader of the faction of Austrasian great nobles in the struggles for hegemony over the waning Merovingian dynasty.

When Clotaire then became sole king of the Franks, he left Warnachar in power in Austrasia briefly, but confirmed at Bonneuil-sur-Marne, in 617, Warnachar's function in Burgundy until his death in 626 (or 627 or 628, when he is said to have called a synod of Burgundian bishops).
