And now, new enemies arose, who, for a long time, troubled England sorely. These were the Northmen, the people of Denmark and Norway, whom the English called the Danes. They were a warlike people, quite at home upon the sea; not Christians; very daring and cruel. They came over in ships, and plundered and burned wheresoever they landed. Once, they beat Egbert in battle. Once, Egbert beat them. But, they cared no more for being beaten than the English themselves. In the four following short reigns, of Ethelwulf, and his sons, Ethelbald, Ethelbert, and Ethelred, they came back, over and over again, burning and plundering, and laying England waste. In the last-mentioned reign, they seized Edmund, King of East England, and bound him to a tree. Then, they proposed to him that he should change his religion; but he, being a good Christian, steadily refused. Upon that, they beat him, made cowardly jests upon him, all defenceless as he was, shot arrows at him, and, finally, struck off his head. It is impossible to say whose head they might have struck off next, but for the death of King Ethelred from a wound he had received in fighting against them, and the succession to his throne of the best and wisest king that ever lived in England.
