Magnus the Good was king of Norway from 1035 and king of Denmark from 1042. The son of Olaf Haraldsson, he returned from exile after the fall of Cnut’s North Sea empire and secured rule with the support of Norwegian magnates. He fought for Denmark against Wendish forces and shared power uneasily with his uncle Harald Hardrada before dying in 1047.
Novels about the generation after Cnut use Magnus to explore the rapid fragmentation of the North Sea empire and the continuing competition among Norwegian, Danish and English claimants. His reputation for severity followed by reconciliation, together with his rivalry with Harald, gives fiction a ruler whose saintly inheritance did not remove the practical demands of war and negotiation.
