African Slave Trade
In the middle of the 15th century Portuguese navigators started exploring the coast of Africa on their search to find a sea route to India. They brought back thousands of slaves every year and sold them on the slave market. By the end of the century they also sold slaves to Spain.
In 1492 Christopher Columbus founded the first settlement in the New World on an island in the Caribbean Sea. A few years later African slaves were brought from Europe, later on they were imported directly from Africa.
