Of what countries was Strut-Harald's half-brother the king?
Harald Bluetooth Harald "Bluetooth" Gormsson (Old Norse: "Haraldr Gormsson" , Danish: "Harald Blåtand Gormsen" , died c. 985/86) was a king of Denmark and Norway.
Settlement of Iceland The settlement of Iceland (Icelandic: "Landnámsöld") is generally believed to have begun in the second half of the 9th century, when Norse settlers migrated across the North Atlantic. The reasons for the migration may be traced to a shortage of arable land in Scandinavia and civil strife brought about by the ambitions of the Norwegian king Harald I of Norway. Unlike the British Isles, Iceland was unsettled land and could be claimed without conflict with existing inhabitants.
