Haakon is not mentioned in any contemporary Anglo-Saxon sources, and later historians of Athelstan, such as William of Malmesbury, make no reference to Haakon. According to Norwegian royal biographies from the late 12th century, the English court introduced him to the Christian religion. On the news of his father's death, King Athelstan provided Haakon with ships and men for an expedition against his half-brother Eric Bloodaxe, who had been proclaimed king of Norway. Historia Norwegiæ describes Haakon as an apostate who observed both pagan and Christian rites.
