Norse settlement of North America in the context of "European colonization in the Americas"

During the Age of Discovery, a large scale colonization of the Americas, involving European countries, took place primarily between the late 15th century and early 19th century. The Norse settled areas of the North Atlantic, colonizing Greenland and creating a short-term settlement near the northern tip of Newfoundland circa 1000 AD. However, due to its long duration and importance, the later colonization by Europeans, after Christopher Columbus’s voyages, is more well-known. During this time, the European colonial empires of Spain, Portugal, Great Britain, France, Russia, the Netherlands, Denmark, and Sweden began to explore and claim the Americas, its natural resources, and human capital, leading to the displacement, disestablishment, enslavement, and genocide of the Indigenous peoples in the Americas, and the establishment of several settler colonial states.

The rapid rate at which some European nations grew in wealth and power was unforeseeable in the early 15th century because it had been preoccupied with internal wars and it was slowly recovering from the loss of population caused by the Black Death. The Ottoman Empire's domination of trade routes to Asia prompted Western European monarchs to search for alternatives, resulting in the voyages of Christopher Columbus and his accidental arrival at the New World. With the signing of the Treaty of Tordesillas in 1494, Portugal and Spain agreed to divide the Earth in two, with Portugal having dominion over non-Christian lands in the world's eastern half, and Spain over those in the western half. Spanish claims essentially included all of the Americas; however, the Treaty of Tordesillas granted the eastern tip of South America to Portugal, where it established Brazil in the early 1500s, and the East Indies to Spain, where It established the Philippines. The city of Santo Domingo, in the current-day Dominican Republic, founded in 1496 by Columbus, is credited as the oldest continuously inhabited European-established settlement in the Americas.

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.

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.
