Why did european countries send colonists to americas

Systematic European colonization began in 1492, when a Spanish expedition headed by the 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". He ran aground on 5 December 1492 on the northern part of Hispaniola, which the Taino people had inhabited since the 9th century; the site became the first permanent European settlement in the Americas. Western 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, Italian explorer John Cabot, on behalf of England, 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 South America.
