He also conquered Cumberland from the Britons; and conferred that territory on Malcolm, king of Scotland, on condition that he should do him homage for it, and protect the north from all future incursions of the Danes.
Edmund was young when he came to the crown; yet was his reign short, as his death was violent.

One day, as he was solemnizing a festival in the county of Glocester, he remarked that Leolf, a notorious robber, whom he had sentenced to banishment, had yet the boldness to enter the hall where he himself dined, and to sit at table with his attendants.

Enraged at this insolence, he ordered him to leave the room; but on his refusing to obey, the king, whose temper, naturally choleric, was inflamed by this additional insult, leaped on him himself, and seized him by the hair; but the ruffian, pushed to extremity, drew his dagger, and gave Edmund a wound of which he immediately expired.

This event happened in the year 946, and in the sixth year of the king's reign.

Edmund left male issue, but so young, that they were incapable of governing the kingdom; and his brother, Edred, was promoted to the throne.
EDRED {946.} The reign of this prince, as those of his predecessors, was disturbed by the rebellions and incursions of the Northumbrian Danes, who, though frequently quelled, were never entirely subdued, nor had ever paid a sincere allegiance to the crown of England.
