The exploration of North America by European sailors and geographers was an effort by major European powers to map and explore the continent with the goal of economic, religious and military expansion. The combative and rapid nature of this exploration is the result of a series of countering actions by neighboring European nations to ensure no single country had garnered enough wealth and power from the Americas to militarily tip the scales over on the European continent. It spanned the late 15th to early 17th centuries, and consisted primarily of expeditions funded by Spain, England, France, and Portugal. See also the European colonization of the Americas.
Pre-Columbian exploration
According to the Sagas of Icelanders, Norse sailors (often called Vikings) from Iceland first settled Greenland in the 980s. Erik the Red explored and settled southwestern Greenland, which he named to entice potential Icelandic settlers, eventually establishing the Eastern and Western Settlements, which were abandoned around 1350.
L'Anse aux Meadows, an archaeological site on the northernmost tip of Newfoundland, and a second site in southwestern Newfoundland, are the only known sites of a Norse village in North America outside of Greenland. These sites are notable for their possible connections with the attempted colony of Vinland established by Leif Erikson in 1003.
Age of Discovery and the search for the Northwest Passage
The Viking voyages did not become common knowledge in the Old World, and Europeans remained unaware of the existence of the Americas as a whole, until the first decades following the year 1492. Many expeditions were launched from European nations in search of a Northwest Passage to East Asia (or "the Indies" as the region was called) in order to establish a shorter trade route to China than the Silk Road, a trade route which had become desperately needed and yet exacerbated by the fall of Constantinople. Also, the Castilian crown needed an alternative to the Portuguese controlled eastern maritime trade route around Africa to India and East Asia.
On August 3, 1492, the Italian navigator Christopher Columbus set sail from the Port of Palos de la Frontera in the Province of Huelva, from the newly los Reyes Católicos coordinated Kingdoms of Castile and Aragon, in present-day Spain, financed by Queen Isabella I of Castille. Columbus's Letter on the First Voyage of his discovery of the Bahamas, Cuba, and Hispaniola spread the news across Europe quickly. Columbus rediscovered and explored much of the Lesser Antilles in his second voyage then discovered both Trinidad and Tobago on his third voyage whilst skirting the northern South American coast. His fourth voyage was spent scanning the Central American coast. The voyages of Christopher Columbus opened the New World.
Italian navigator and explorer Giovanni Caboto (known in English as John Cabot) is credited with the discovery of continental North America on June 24, 1497, under the commission of Henry VII of England. Though the exact location of his discovery remains disputed, the Canadian and United Kingdom governments' official position is that he landed on the island of Newfoundland. The English presence through Giovanni Caboto was signaled in Juan de la Cosa's map of 1500.
In 1499 João Fernandes Lavrador was licensed by the King of Manuel I of Portugal and together with Pêro de Barcelos they reached Greenland and sighted Labrador for the first time since Leif Erikson, which was granted and named after Lavrador. After returning he possibly went to Bristol to sail in the name of England. Nearly at the same time, between 1499 and 1502 the brothers Gaspar and Miguel Corte Real explored and named the coasts of Greenland, Labrador and also Newfoundland, naming "Terra Verde" the explored North American coasts. Both explorations were signaled in 1502 Cantino planisphere.
It was soon understood that Columbus had not reached Asia, but rather found what was to Europeans a New World, which in 1507 was named "America", after Amerigo Vespucci, on the Waldseemüller map.
Further nautical explorations
In 1500, Pedro Álvares Cabral was sent by Portugal to explore South America. He is considered to be the discoverer of Brazil.
