Magnus the Good
Magnus Olafsson, called the Good (1024–1047), was the illegitimate son of St. Olaf of Norway. When Cnut the Great deposed his father in 1028, he took refuge at the court of Yaroslav the Wise in Kiev, returning in 1035 to be crowned king of Norway at eleven.
In 1042 he also became king of Denmark and fought Sven Estridsson for the kingdom. In 1046 he accepted his uncle Harald Hardrada as co-king of Norway. Magnus died in Denmark on 25 October 1047, and the two crowns passed to Harald and Sven.
