Since Ebbo had been installed and removed several times as Archbishop of Reims, Altfrid took the unusual step of repeating all consecrations and ordinations of his predecessor to avoid their invalidation.
[a] Altfrid also supported the Saxon Count Ricdag in the foundation of the nunnery at Lamspringe by procuring for it the relics of Saint Hadrian from Rome.
[2] Altfrid, was a close confidant of Ludwig the German, and from 860 took an influential role in the power struggles between the various parts of the disintegrating Frankish empire.
In 860 Altfrid was present at the meeting between Ludwig the German and Charles the Bald in St. Castor's Basilica in Koblenz, where the two kings agreed a peace treaty.
[2] The place of Altfrid's death is not known, although the date is recorded by Abbot Altbert of Lobbes as the feast of the Assumption of the Virgin Mary, i.e., 15 August 874.
Around the year 1000 miracles were reported at his grave, which greatly increased the veneration, and the effects of a supposedly healing spring close to the church were also ascribed to his intercession.
After the foundation of the Bishopric of Essen in 1958 the first bishop asked Rome to confirm the celebration of Altfrid's feast day as an official church festival, a request which was granted in 1965.
