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.
Ingvar the Far-Travelled Ingvar the Far-Travelled (Old Norse: "Yngvarr víðförli", Swedish: "Ingvar Vittfarne") led an unsuccessful large Viking attack against Persia in 1036–1042. His inscriptions claim that he launched expeditions against the barbarians Saracens and further tried to reach the East, the Greater India to establish trade links.
