11. =Eadward and the Scots.=--Tradition assigns to Eadward a wider rule shortly before his death. In the middle of the ninth century the Picts and the intruding Scots (see p. 42) had been amalgamated under Keneth MacAlpin, the king of the Scots, and the new kingdom had since been welded together, just as Mercia and Wessex were being welded together by the attacks of the Danes. It is said that in =925= the king of the Scots, together with other northern rulers, chose Eadward 'to father and lord.' Probably this statement only covers some act of alliance formed by the English king with the king of Scots and other lesser rulers. Nothing was more natural than that the Scottish king, Constantine, should wish to obtain the support of Eadward against his enemies; and it was also natural that if Eadward agreed to support him, he would require some acknowledgment of the superiority of the English king; but what was the precise form of the acknowledgment must remain uncertain. In =925= Eadward died. 12. =AEthelstan. 925--940.=--Three sons of Eadward reigned in succession. The eldest, of illegitimate birth, was AEthelstan. Sihtric, the Danish king at York, owned him as over-lord, and on Sihtric's death in =926=, AEthelstan took Danish North-humberland under his direct rule. The Welsh kings were reduced to make a fuller acknowledgment of his supremacy than they had made to his father. He drove the Welsh out of the half of Exeter which had been left to them, and confined them to the modern Cornwall beyond the Tamar. Great rulers on the Continent sought his alliance. The empire of Charles the Great had broken up. One of AEthelstan's sisters was given to Charles the Simple, the king of the Western Franks; another to Hugh the Great, Duke of the French and lord of Paris, who, though nominally the vassal of the king, was equal in power to his lord, and whose son was afterwards the first king of modern France. A third sister was given to Otto, the son of Henry, the king of the Eastern Franks, from whom, in due time, sprang a new line of Emperors. AEthelstan's greatness drew upon him the jealousy of the king of the Scots and of all the northern kings. In =937= he defeated them all in a great battle at Brunanburh, of which the site is unknown. His victory was celebrated in a splendid war-song.
