11. The Greatness of Eadwine.—Powerful as Æthelfrith was, he was jealous of young Eadwine, a son of his father's rival, Ælla of Deira. For some years Eadwine had been in hiding, at one time with Welsh princes, at another time with English kings. In 617 he took refuge with Rædwald, the king of the East Angles. Æthelfrith demanded the surrender of the fugitive. Rædwald hesitated, but at last refused. Æthelfrith attacked him, but was defeated and slain near the river Idle, at some point near Retford. Eadwine the Deiran then became king over the united North-humberland in the place of Æthelfrith the Bernician, whose sons fled for safety to the Picts beyond the Forth. Eadwine completed and consolidated the conquests of his predecessors. He placed a fortress, named after himself Eadwinesburh, or Edinburgh, on a rocky height near the Forth, to guard his land against a fresh irruption of Scots and Picts, such as that which had been turned back at Degsastan. He conquered from the Kymry Loidis and Elmet, and he launched a fleet at Chester which added to his dominions the Isle of Man and the greater island which was henceforth known as Anglesea, the island of the Angles. Eadwine assumed unwonted state. Wherever he went a standard was borne before him, as well as a spear decorated with a tuft of feathers, the ancient sign of Roman authority. It has been thought by some that his meaning was that he, rather than any Welshman, was the true Gwledig, the successor of the Duke of the Britains (Dux Britanniarum), and that the name of Bretwalda, or ruler of the Britons, which he is said to have borne, was only a translation of the Welsh Gwledig. It is true that the title of Bretwalda is given to other powerful kings before and after Eadwine, some of whom were in no sense rulers over Britons; but it is possible that it was taken to signify a ruler over a large part of Britain, though the men over whom he ruled were English, and not Britons.
12. Eadwine's Supremacy.—Eadwine's immediate kingship did not reach further south than the Humber and the Dee. But before 625 he had brought the East Angles and the kingdoms of central England to submit to his over-lordship, and he hoped to make himself over-lord of the south as well, and thus to reduce all England to dependence on himself. In 625 he planned an attack upon the West Saxons, and with the object of winning Kent to his side, he married Æthelburh, a sister of the Kentish king. Kent was still the only Christian kingdom, and Eadwine was obliged to promise to his wife protection for her Christian worship. He was now free to attack the West Saxons. In 626, before he set out, ambassadors arrived from their king. As Eadwine was listening to them, one of their number rushed forward to stab him. His life was saved by the devotion of Lilla, one of his thegns, who threw his body in the way of the assassin, and was slain by the stroke intended for his lord. After this Eadwine marched against the West Saxons. He defeated them in battle and forced them to acknowledge him as their over-lord. He was now over-lord of all the English states except Kent, and Kent had become his ally in consequence of his marriage.
13. Character of the later Conquests.—Eadwine's over-lordship had been gained with as little difficulty as Æthelberht's had been. The ease with which each of them carried out their purpose can only be explained by the change which had taken place in the condition of the English. The small bodies of conquerors which had landed at different parts of the coast had been interested to a man in the defence of the lands which they had seized. Every freeman had been ready to come forward to defend the soil which his tribe had gained. After tribe had been joined to tribe, and still more after kingdom had been joined to kingdom, there were large numbers who ceased to have any interest in resisting the Welsh on what was, as far as they were concerned, a distant frontier. Thus, when Ceawlin was fighting to extend the West Saxon frontiers in the valley of the Severn, it mattered little to a man whose own allotted land lay on the banks of the Southampton Water whether or not his English kinsmen won lands from the Welsh near Bath or Gloucester. The first result of this change was that the king's war-band formed a far greater proportion of his military force than it had formed originally. There was still the obligation upon the whole body of the freemen to take arms, but it was an obligation which had become more difficult to fulfil, and it must often have happened that very few freemen took part in a battle except the local levies concerned in defending their own immediate neighbourhood. A military change of this kind would account for the undoubted fact that the further the English conquest penetrated to the west the less destructive it was of British life. The thegns, or warriors personally attached to the king, did not want to plough and reap with their own hands. They would be far better pleased to spare the lives of the conquered and to compel them to labour. Every step in advance was marked by a proportionately larger Welsh element in the population.
14. Political Changes.—The character of the kingship was as much affected by the change as the character of the population. The old folk-moots still remained as the local courts of the smaller kingdoms, or of the districts out of which the larger kingdoms were composed, and continued to meet under the presidency of ealdormen appointed or approved by the king. Four men and a reeve, all of them humble cultivators, could not, however, be expected to walk up to York from the shores of the Forth, or even from the banks of the Tyne, whenever Eadwine needed their counsel. Their place in the larger kingdoms was therefore taken by the Witenagemot (The moot of the wise men), composed of the ealdormen and the chief thegns, together with the priests attached to the king's service in the time of heathendom, and, in the time of Christianity, the bishop or bishops of his kingdom. In one way the king was the stronger for the change. His counsellors, like his fighting force, were more dependent on himself than before. He was able to plan greater designs, and to carry out military enterprises at a greater distance. In another way he was the weaker for the change. He had less support from the bulk of his people, and was more likely to undertake enterprises in which they had no interest. The over-lordships of Æthelberht and Eadwine appear very imposing, but no real tie united the men of the centre of England to those of Kent at one time, or to those of North-humberland at another. Eadwine was supreme over the other kings because he had a better war-band than they had. If another king appeared whose war-band was better than his, his supremacy would disappear.
15. Eadwine's Conversion and Fall.—In 627 Eadwine, moved by his wife's entreaties and the urgency of her chaplain, Paulinus, called upon his Witan to accept Christianity. Coifi, the priest, declared that he had long served his gods for naught, and would try a change of masters. 'The present life of man, O king,' said a thegn, 'seems to me in comparison of that time which is unknown to us like to the swift flight of a sparrow through the room wherein you sit at supper in winter, with your ealdormen and thegns, and a good fire in the midst, and storms of rain and snow without.... So this life of man appears for a short space, but of what went before or what is to follow we are utterly ignorant. If therefore this new doctrine contains something more certain, it seems justly to deserve to be followed.' On this recommendation
