colonization of the
Americas describes the history of the invasion, settlement and establishment of control of the continents of the Americas by various European powers.
The first European colonisation in the Americas began in the 10th or 11th century, when
West Norse sailors explored and briefly settled limited areas on the shores of present-day
Canada. They settled in
Greenland before sailing to the
Arctic region of
North America and south alongside Canada where they settled there.
 According to
Icelandic Sagas, violent conflicts with the indigenous population ultimately made the Norse abandon those settlements.
Extensive European colonization began in 1492, when a Spanish
expedition headed by Italian explorer
Christopher Columbus sailed west to find a new trade route to the
Far East but inadvertently landed in what came to be known to Europeans as the "
New World". Running aground on the northern part of
Hispaniola on 5 December 1492, which the
Taino people had inhabited since the 7th century, the site became the first European settlement in the Americas. European conquest, large-scale exploration and colonization soon followed. Columbus's first two voyages (1492–93) reached the
Bahamas and various
Caribbean islands, including Hispaniola,
Puerto Rico and
Cuba. In 1497, sailing from
Bristol on behalf of
John Cabot landed on the
North American coast, and a year later, Columbus's
third voyage reached the South American coast. As the sponsor of
Christopher Columbus's voyages,
Spain was the first European power to settle and colonize the largest areas, from North America and the
Caribbean to the southern tip of
Other powers such as
France also founded colonies in the Americas: in eastern North America, a number of Caribbean islands and small coastal parts of South America.
Brazil, tried colonizing the coasts of present-day Canada and settled for extended periods northwest (on the east bank) of the
River Plate. The
Age of Exploration was the beginning of territorial expansion for several European countries. Europe had been preoccupied with internal wars, and was slowly recovering from the loss of population caused by the
bubonic plague; thus the rapid rate at which it grew in wealth and power was unforeseeable in the early 15th century.
Eventually, the entire
Western Hemisphere came under the ostensible control of European governments, leading to profound changes to its landscape, population, and plant and animal life. In the 19th century alone over 50 million people left Europe for the Americas.
 The post-1492 era is known as the period of the
Columbian Exchange, a dramatically widespread exchange of animals, plants, culture, human populations (including
slaves), ideas and
communicable disease between the American and Afro-Eurasian hemispheres following Columbus's voyages to the Americas.
