Records of European travel to North America begin with the Norse colonization in the tenth century A.D. In 985, they founded a settlement on Greenland (an often-overlooked part of North America) that persisted until the early 1400s. They also explored the east coast of Canada, but their settlements there were much smaller and shorter-lived. With the Age of Exploration and the voyages of Christopher Columbus (starting 1492), Europeans began to arrive in the Americas in large numbers and to develop colonial ambitions for both North and South America. Columbus' "discovery" of America is a contested idea because the Americas were already heavily populated by the indigenous peoples of the Americas, who had developed distinctive civilizations in their own right. After Columbus, influxes of Europeans soon followed and overwhelmed the native population. North America became a staging ground for ongoing European rivalries. The continent was divided by three prominent European powers: England, France, and Spain. The influences of colonization by these states on North American cultures are still apparent today.
