Magnus, King Olaf's son, was, immediately after King Olaf's death, proclaimed at Viken king of all Norway; but the Upland people, on hearing of King Olaf's death, chose Hakon, Thorer's foster-son, a cousin of King Magnus, as king.
Thereupon Hakon and Thorer went north to the Throndhjem country, and when they came to Nidaros they summoned the Eyrathing; and at that Thing Hakon desired the bondes to give him the kingly title, which was agreed to, and the Throndhjem people proclaimed him king of half of Norway, as his father, King Magnus, had been before. Hakon relieved the Throndhjem people of all harbour duties, and gave them many other privileges. He did away with Yule-gifts, and gained by this the good-will of all the Throndhjem people.
Thereafter Hakon formed a court, and then proceeded to the Uplands, where he gave the Upland people the same privileges as the Throndhjem people; so that they also were perfectly well affected to him, and were his friends.
The people in Throndhjem sang this ballad about him: —
"Young Hakon was the Norseman's pride,
And Steig-Thorer was on his side.
Young Hakon from the Upland came,
With royal birth, and blood, and name.
Young Hakon from the king demands
His royal birthright, half the lands;
Magnus will not the kingdom break, —
The whole or nothing he will take."
