latter part of the 8th century Mercia became the predominant kingdom under Offa, and he determined to have an archbishop of his own. By his contrivance two legates from Adrian I. held a council at Chelsea in 787 in which Lichfield was declared an archbishopric, and seven of the twelve suffragan bishoprics of Canterbury were apportioned to it. In 802, however, Leo III. restored Canterbury to its rights and the Lichfield archbishopric was abolished. Later Anglo-Saxon times. The rise of Wessex to power seems to have been aided by a good understanding between Ecgbert and the church, and his successors employed bishops as their ministers. Æthelred, who was specially under ecclesiastical influence, went on a pilgrimage to Rome, and before his departure made large grants for pious uses. His donation, though not the origin of tithes in England, illustrates the idea of the sacredness of the tenth of income on which laws enforcing the payment of tithes were founded. His pilgrimage was probably undertaken in the hope of averting the attacks of the pagan Danes. Their invasions fell heavily on the church; priests were slaughtered and churches sacked and burnt. Learning disappeared in Northumbria, and things were little better in the south. Bishops fought and fell in battle, the clergy lived as laymen, the monasteries were held by married canons, heathen superstitions and immorality prevailed among the laity. Besides bringing the Danish settlers in East Anglia to profess Christianity in 878, Alfred set himself to improve the religious and intellectual condition of his own people (see ALFRED). The gradual reconquest of middle and northern England by his successors was accompanied by the conversion of the Danish population. A revival of religion was effected by churchmen inspired by the reformed monasticism of France and Flanders, by Odo, archbishop of Canterbury, Oswald, archbishop of York, and Dunstan (see DUNSTAN), who introduced from abroad the strict life of the new Benedictinism. King Edgar promoted the monastic reform, and by his authority Bishop Æthelwold of Winchester turned canons out of the monasteries and put monks in their place. Dunstan sought to reform the church by ecclesiastical and secular legislation, forbidding immorality among laymen, insisting on the duties of the clergy, and compelling the payment of tithes and other church dues. After Edgar's death an anti-monastic movement, chiefly in Mercia, nearly ended in civil war. In this strife, which was connected with politics, the victory on the whole lay with the monks' party, and in many cathedral churches the chapters remained monastic. The renewed energy of the church was manifested by councils, canonical legislation and books of sermons. In the homilies of Abbot Ælfric, written for Archbishop Sigeric, stress is laid on the purely spiritual presence of Christ in the Eucharist, but his words do not indicate, as some have believed, that the English Church was not in accord with Rome.
