Liutward was the archchancellor of the Carolingian Empire from 878 and the bishop of Vercelli from 880 by appointment of Charles the Fat. Never liked by the nobility, he was trusted by Charles as a confidante and go-between with the papacy.
In 887, he was accused by Charles of having an affair with the Empress Richardis and though the empress successfully underwent the ordeal of fire, he was banished from court. Liutward's men abducted the daughter of Unroch III of Friuli from a convent in Brescia and forced her to marry one of his relatives. This provoked enmity between Liutward, the chief Carolingian prelate in Lombardy, and Berengar of Friuli, the chief secular magnate.
The famed poet of the age, Notker of St Gall, dedicated a series of verses to him between the years 881 and 887.
