HAAKON I., surnamed "the Good" (d. 961), was the youngest son of Harald Haarfager. He was fostered by King Aethelstan of England, who brought him up in the Christian religion, and on the news of his father's death in 933 provided him with ships and men for an expedition against his half-brother Erik, who had been pro claimed king. On his arrival in Norway Haakon gained the sup port of the landowners by promising to give up the rights of taxa tion claimed by his father over inherited real property. Erik fled, and was killed a few years later in England. His sons allied them selves with the Danes, but were invariably defeated by Haakon, who was successful in everything he undertook except in his attempt to introduce Christianity, which aroused an opposition he did not feel strong enough to face. He was killed at the battle of Fitje in 961, after a final victory over Erik's sons.
