Magnus I (of Norway and Denmark), called The Good (1024-47), king of Norway (1035-47) and Denmark (1042-47). The son of Olaf II, he grew up in Russia but was accepted as king in Norway on the death of Canute II. He helped King Hardecanute of Denmark against the Wends in return for the agreement that if either of them died without heir, the other would succeed him. Magnus accordingly became king of Denmark in 1042, and the following year he won a decisive victory over the Wends. He laid a claim to the English throne, too, but could not follow it up. He was succeeded in Norway by his uncle, Harold III.
