Pope John VIII dedicated the new church about the year 877, from which time the patronage of Peter appears to have prevailed definitively.
The monastery was at the height of its reputation in the eighth century, in the time of the Abbot Manasses, who was appointed by Pippin the Short.
[4] Pippin's successor, Charlemagne, authorized Manasses to found the Carolingian style monastery of Corbigny.
Charlemagne's son, Louis the Pious, used Abbot Adrevaldus as an envoy to Septimania in 834 and 838, according to the Historia Hludowici imperatoris.
[5] At Flavigny were preserved the relics of Saint Regina, whom her acts represent as having been beheaded as a martyr in the town of Alise (since called after her Alise-Sainte-Reine).
The next abbot to be appointed, Heldric, was a Cluniac monk who restored regular monastic life to Flavigny.
[7] Heldric's successor, Amadeus, restored abbatial control over Corbigny and established new monastic houses at Couches, Semur and Beaulieu.
After the abbacy of Raynald (1084–90), a brother of Duke Odo I of Burgundy, the post was vacant for seven years (except for the two-month rule of one Elmuin).
He wrote a Chronicle, a Martyrology and a Necrology, but according to church historian Henri Leclercq they "have either perished or contain few facts of real interest".
Two years after the French Revolution, the monks fled from the abbey which was sold and divided into various private properties.
