Anecdotes
After becoming Archbishop of Reims in 969, Adalberon surrounded himself with the greatest scholar of his time, Gerbert of Aurillac, whom he placed at the head of the episcopal school. Reims then became one of the great intellectual centers of the West, where astronomy, mathematics, and logic were taught.
The Carolingian king Lothair violently reproached Adalberon for his closeness to the Ottonian emperors of Germany. In 985, the archbishop was even summoned to answer a charge of treason, but the king's death in 986 caused the proceedings to be dropped.
In 987, when the young Louis V died without an heir, Adalberon delivered a decisive speech before the great lords of the kingdom, asserting that kingship was not transmitted by blood alone but should pass to the most worthy. He thus had Hugh Capet elected.
It was Adalberon himself who crowned Hugh Capet at Noyon in 987, placing the crown upon the head of the founder of a dynasty that would reign over France for more than eight centuries.
At his death in 989, Adalberon wished for his disciple Gerbert of Aurillac to succeed him on the see of Reims. But the new king Hugh Capet first preferred Arnulf, a Carolingian bastard, which triggered a long ecclesiastical quarrel.
Primary Sources
Adalbero, recalling that royal dignity is not acquired by hereditary right, urged the magnates to choose a king commendable for the nobility of his body and mind, and designated Hugh, Duke of the Franks.
Gerbert, writing on behalf of Archbishop Adalbero, attests to the trust the latter placed in him for conducting the affairs of the Church of Reims and to his role as a counselor.
The assembled bishops evoked the memory of Adalbero and the question of his succession to the archiepiscopal see of Reims, a matter of discord between Gerbert and Arnulf.
