Coenwulf wanted all the English churches placed under the authority of a single archbishop. But he wanted him seated in London, not Canterbury. He managed to abolish the of Lichfield in 803. Coenwulf tried to convince the pope on moving the remaining archbishopric to London. But the pope felt that Coenwulf's success in bringing Kent under his control meant the move was no longer necessary. So the archbishop remained in Canterbury, Kent. When Archbishop Aethelheard died in 805, his Wulfred was appointed the new archbishop. Wulfred witnessed charters for Coenwulf from 805 to 817 but then promptly stopped. Archbishop Wulfred and King Coenwulf quarreled for several years. It may have started over a claim by Coenwulf to various lands held by the see of Canterbury. Wulfred in turn began minting coins without the name of King Coenwulf. Finally in 817 Coenwulf took Wulfred's monasteries of Reculver and Minster-in-Thanet. Then he brought charges against Wulfred to Pope Paschal I. As a result, Wulfred was relieved of many of his duties by the pope. In 821 Coenwulf summoned the archbishop to appear before him in London. There Wulfred was fined 120 pounds and an estate of 250 hides He was then restored to his duties as archbishop. In 818 he was again attacking the Britons in Dyfed. He was planning another campaign against Wales when he died in 821. He was succeeded by his brother Ceolwulf I of Mercia. Coenwulf was buried at Winchcombe abbey where his daughter Cwenthryh was later . A lead seal belonging to King Coenwulf was found during the 19th century in Italy. It is now in the British Museum.
