History of Greenland in the context of "Vikings"

The Greenlandic Inuit or sometimes simply the Greenlandic are an ethnic group and nation Indigenous to Greenland, where they constitute the largest ethnic population. They share a common ancestry, culture, and history; and natively speak the Greenlandic language. As Greenland is a territory within the Danish Realm, citizens of Greenland are both citizens of Denmark and of the European Union.

Approximately 89 percent of Greenland's population of 57,695 is Greenlandic Inuit, or 51,349 people as of 2012. Ethnographically, they consist of three major groups:

Viking expansion was the historical movement which led Vikings, to sail most of the North Atlantic, reaching south as far as North Africa and east as far as Russia, and through the Mediterranean as far as Constantinople and the Middle East, acting as looters, traders, colonists and mercenaries. To the west, Vikings under Leif Erikson (the heir to Erik the Red) reached North America and set up a short-lived settlement in present-day L'Anse aux Meadows, Newfoundland, Canada. Longer lasting and more established Norse settlements were formed in Greenland, Iceland, the Faroe Islands, Russia, Ukraine, Great Britain, Ireland, Normandy and Sicily.

Leif Erikson, also known as Leif the Lucky (c. 970s – c. 1018 to 1025), was a Norse explorer who is thought to have been the first European to set foot on continental America, approximately half a millennium before Christopher Columbus. According to the sagas of Icelanders, he established a Norse settlement at Vinland, which is usually interpreted as being coastal North America. There is ongoing speculation that the settlement made by Leif and his crew corresponds to the remains of a Norse settlement found in Newfoundland, Canada, called L'Anse aux Meadows, which was occupied approximately 1,000 years ago.

Leif's place of birth is unknown, although it is assumed to have been in Iceland. His father, Erik the Red, founded the first Norse settlement in Greenland, where Leif was later raised. Following his voyage to Vinland and the subsequent death of his father, Leif became chief of the Greenland settlement. He had two known sons: Thorgils, born in the Hebrides; and Thorkell, who succeeded him as Greenland's chieftain.

Pre-Columbian transoceanic contact theories, many of which are speculative, propose that visits to the Americas, interactions with the Indigenous peoples of the Americas, or both, were made by people from elsewhere prior to Christopher Columbus's first voyage to the Caribbean in 1492. Studies between 2004 and 2009 suggest the possibility that the earliest human migrations to the Americas may have been made by boat from Beringia and travel down the Pacific coast, contemporary with and possibly predating land migrations over the Beringia land bridge, which during the glacial period joined what today are Siberia and Alaska. Apart from Norse contact and settlement, whether transoceanic travel occurred during the historic period, resulting in pre-Columbian contact between the settled American peoples and voyagers from other continents, is vigorously debated.

Only a few cases of pre-Columbian contact are widely accepted by mainstream scientists and scholars. Yup'ik and Aleut peoples residing on both sides of the Bering Strait had frequent contact with each other, and European trade goods have been discovered in pre-Columbian archaeological sites in Alaska. Maritime explorations by Norse peoples from Scandinavia during the late 10th century led to the Norse colonization of Greenland and a base camp L'Anse aux Meadows in Newfoundland, which preceded Columbus's arrival in the Americas by some 500 years. Recent genetic studies have also suggested that some eastern Polynesian populations have admixture from coastal western South American peoples, with an estimated date of contact around 1200 CE.
