The Norse colonization of North America began in the late 10th century AD when Norsemen explored and settled areas of the North Atlantic including the northeastern fringes of North America. Viking houses were found at L’Anse aux Meadows near the northern tip of Newfoundland in 1960. This discovery aided the reignition of archaeological exploration for the Vikings in the north Atlantic.
The Norse colony in Greenland lasted for almost 500 years. Continental North American settlements were small and did not develop into permanent colonies. While voyages, for example to collect timber, are likely to have occurred for some time, there is no evidence of any lasting Norse settlements on mainland North America.
According to the Sagas of Icelanders, Norsemen from Iceland first settled Greenland in the 980s. There is no special reason to doubt the authority of the information that the sagas supply regarding the very beginning of the settlement, but they cannot be treated as primary evidence for the history of Norse Greenland because they embody the literary preoccupations of writers and audiences in medieval Iceland that are not always reliable.
Erik the Red (Old Norse: Eiríkr rauði), having been banished from Iceland for manslaughter, explored the uninhabited southwestern coast of Greenland during the three years of his banishment. He made plans to entice settlers to the area, naming it Greenland on the assumption that "people would be more eager to go there because the land had a good name". The inner reaches of one long fjord, named Eiriksfjord after him, was where he eventually established his estate Brattahlid. He issued tracts of land to his followers.
At its peak the colony consisted of two settlements. The Eastern was at the southwestern tip of Greenland, while the Western Settlement was about 500 km up the west coast, inland from present-day Nuuk. A smaller settlement near the Eastern Settlement is sometimes considered the Middle Settlement. The combined population was around 2,000–3,000. At least 400 farms have been identified by archaeologists. Norse Greenland had a bishopric (at Garðar) and exported walrus ivory, furs, rope, sheep, whale or seal blubber, live animals such as polar bears, supposed "unicorn horns" (in reality narwhal tusks), and cattle hides. In 1126, the population requested a Bishop (headquartered at Garðar), and in 1261, they accepted the overlordship of the Norwegian King. They continued to have their own law and became almost completely independent after 1349, the time of the Black Death. In 1380, the Norwegian Kingdom entered into a personal union with the Kingdom of Denmark.
