Greenland saga relates to the colonization of Greenland by the viking of what nationality?
Erik the Red Erik Thorvaldsson (Old Norse: "Eiríkr Þorvaldsson" ; 950 – c. 1003), known as Erik the Red (Old Norse: "Eiríkr hinn rauði" ) was a Norwegian Viking, remembered in medieval and Icelandic saga sources as having founded the first Norse settlement in Greenland. The Icelandic tradition indicates that he was born in the Jæren district of Rogaland, Norway, as the son of Þorvald Ásvaldsson, he therefore also appears, patronymically, as Erik Thorvaldsson ("Eiríkr Þorvaldsson"). The appellation "the Red" most likely refers to his hair color and the color of his beard. Leif Erikson, the famous Icelandic explorer, was Erik's son.
Magnus IV of Sweden Magnus IV (April or May 1316  – 1 December 1374; Swedish "Magnus Eriksson") was King of Sweden from 1319 to 1364, King of Norway as Magnus VII (including Iceland and Greenland) from 1319 to 1343, and ruler of Scania from 1332 to 1360. By adversaries he has been called "Magnus Smek" (English: "Magnus the Caresser").
