The changes which took place were limited as yet to a small part of England. In three months after his coronation William was still without authority beyond an irregular line running from the Wash to the western border of Hampshire, except that he held some outlying posts in Herefordshire. It is true that Eadwine and Morkere had acknowledged him as king, but they were still practically independent. Even where William actually ruled he allowed all Englishmen who had not fought on Harold's side to keep their lands, though he made them redeem them by the payment of a fine, on the principle that all lands in the country, except those of the Church, were the king's lands, and that it was right to fine those who had not come to Senlac to help him as their proper lord. 2. =The Conquest of the West and North. 1067--1069.=--In March =1067= William returned to Normandy. In his absence the Normans left behind in England oppressed the English, and were supported in their oppression by the two regents appointed to govern in William's name, his half-brother, Odo, Bishop of Bayeux, whom he had made Earl of Kent, and William Fitz-Osbern, Earl of Hereford. In some parts the English rose in rebellion. In December William returned, and after putting down resistance in the south-eastern counties, set himself to conquer the rest of England. It took him more than two years to complete his task. Perhaps he would have failed even then if the whole of the unconquered part of the country had risen against him at the same time. Each district, however, resisted separately, and he was strong enough to beat them down one by one. In the spring of =1068= he besieged and took Exeter, and subdued the West to the Land's End. When this had been accomplished he turned northwards against Eadwine and Morkere, who had declared against him. William soon frightened them into submission, and seized on York and all the country to the south of York on the eastern side of England. In =1069= the English of the North rose once more and summoned to their aid Svend, king of Denmark, a nephew of the great Cnut. Svend sent a Danish fleet, and the Danes were joined by Eadgar the AEtheling and by other English chiefs. They burnt and plundered York, but could do no more. Their great host melted away. The Danes went off with their booty to their ships, and the English returned to their homes. William found no army to oppose him, and he not only regained the lands which he had occupied the year before, but added to them the whole country up to the Tweed.
