David Hume - The History of England, Vol.I. Part A. ( Chap 2.8) lyrics

Edmund Edmund, on his accession, met with disturbance from the restless Northumbrians, who lay in wait for every opportunity of breaking into rebellion. But marching suddenly with his forces into their country, he so overawed the rebels that they endeavored to appease him by the most humble submissions.[*]   [* W. Malms, lib. ii. cap. 7. Brompton, p 857.] In order to give him the surer pledge of their obedience, they offered to embrace Christianity; a religion which the English Danes had frequently professed, when reduced to difficulties, but which, for that very reason, they regarded as a badge of servitude, and shook off as soon as a favorable opportunity offered. Edmund, trusting little to their sincerity in this forced submission, used the precaution of removing the Five-burgers from the towns of Mercia, in which they had been allowed to settle; because it was always found that they took advantage of every commotion, and introduced the rebellious or foreign Danes into the heart of the kingdom. 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 d**h 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.
