The importance of Somerset during the reign of the Saxon kings who succeeded Alfred is evidenced by the many noteworthy incidents that are connected with its chief city, Bath, and its great abbey of Glastonbury. It was at Bath that King Edgar was crowned in 973; and at the same place at a later date (1013) the Danish king, Sweyn, received the submission of the western thegns. At Glastonbury were buried three of the Saxon kings, Edmund (son of Edward the Elder), Edgar, and Edmund Ironside. Here too was born Dunstan, who was so prominent an ecclesiastic in the reigns of the first Edmund and five of his successors. He was made abbot of the abbey by Edmund, and, after becoming Archbishop of Canterbury, was buried at Glastonbury (988). Two other Somerset men who filled the see of Canterbury during the Saxon period were Ethelgar and Alphege. Under the Plantagenets the history of the county was not very eventful, though some localities suffered severely in the disturbances of the Norman period. In William Rufus' reign it was the scene of several of the movements directed against the king in favour of his brother Robert. The powerful baron-bishop, Geoffrey of Coutances, with his nephew Robert of Mowbray, after seizing Bristol, burnt Bath, but was unsuccessful in the siege of Ilchester (1088). On the death of Henry I. Somerset favoured the claims of Matilda, and the castles at Cary, E. Harptree, and Dunster were held by their owners for her against Stephen, to the no small discomfort of their respective neighbourhoods. Castle Cary and Harptree were taken by Stephen, but he seems to have regarded Dunster (defended by William of Mohun) as impregnable. In Tudor times Somerset witnessed the attempt made on the throne by Perkin Warbeck in 1497, who was supported by Lord Audley of Nether Stowey and other Somerset gentlemen. The pretender advanced from Devonshire to seize Taunton; but when Henry VII. entered Somerset, passing in his progress through Bath, Wells (where he stayed with the Dean), and Glastonbury, to Taunton, Warbeck lost heart and fled. When captured and brought into Henry's presence he was spared; but the king's clemency did not extend to his supporter Lord Audley, who was executed on Tower Hill.
