"The earliest Palaeo-Eskimo cultures had already arrived in Greenland from Canada by c.2,500 BC The Thule Eskimo culture first arrived in N Greenland c.AD 900 and in the following 1,000 years spread to both W and E Greenland. From Iceland, Greenland was discovered and S Greenland colonized (c.985) by Eric the Red , a Norseman, who named it Greenland in order to make it seem attractive to potential settlers. It was in sailing to Greenland (c.1000) that Leif Ericsson , the son of Eric the Red, probably reached North America. Greenland became a bishopric c.1110, and ruins of churches of that period remain. By the 12th cent. the population numbered some 10,000."
