This prince, who mounted the throne in 755,[*] had some great qualities, and was successful in his warlike enterprises against Lothaire, king of Kent, and Kenwulph, king of Wessex, He defeated the former in a bloody battle, at Otford upon the Darent, and reduced his kingdom to a state of dependence; he gained a victory over the latter at Bensington, in Oxfordshire; and conquering that county, together with that of Glocester, annexed both to his dominions. But all these successes were stained by his treacherous murder of Ethelbert, king of the East Angles, and his violent seizing of that kingdom. This young prince, who is said to have possessed great merit, had paid his addresses to Elfrida, the daughter of Offa, and was invited with all his retinue to Hereford, in order to solemnize the nuptials: amidst the joy and festivity of these entertainments, he was seized by Offa, and secretly beheaded; and though Elfrida, who abhorred her father’s treachery, had time to give warning to the East Anglian nobility, who escaped into their own country, Offa, having extinguished the royal family, succeeded in his design of subduing that kingdom.[**] The perfidious prince, desirous of reestablishing his character in the world, and perhaps of appeasing the remorses of his own conscience, paid great court to the clergy, and practised all the monkish devotion so much esteemed in that ignorant and superstitious age. He gave the tenth of his goods to the church;[***] bestowed rich donations on the cathedral of Hereford, and even made a pilgrimage to Rome, where his great power and riches could not fail of procuring him the papal absolution. The better to ingratiate himself with the sovereign pontiff, he engaged to pay him a yearly donation for the support of an English college at Rome,[****] and in order to raise the sum, he imposed a tax of a penny on each house possessed of thirty pence a year. This imposition, being afterwards levied on all England, was commonly denominated _Peter’s pence_;[*****] and though conferred at first as a gift, was afterwards claimed as a tribute by the Roman pontiff.

Offa died, after a reign of thirty-nine years, in 794.[***]
