The influence on African slave trade from the 16th century to the 19th century was very great. The economy of the country that allows African slave trade is growing. For example, the United States is a huge land with no relation before trading, started to raise some profit in agriculture, and increased significantly between populations. They are using a lot of African slaves to cultivate and work. This created a better economy in the United States. In addition, only 1 million Europeans went to the Western Hemisphere.
Slave trade beyond the Atlantic, which is part of the global slave trade, enslaved the 10 million to 12 million Atlantic slaves to the Americas from the 16th century to the 19th century. This is the second of three phases of so-called triangular trade. There, weapons, textiles and wines are sent from Europe to Africa, slaves from Africa to America, and sugar and coffee from America to Europe. By the 1480's, the Portuguese ship carried Africans as slaves to the Eastern Atlantic Cape Verde and Madeira Sugar Plantation. After 1502, the Spanish conquistadors took slaves of Africa to the Caribbean, but the Portuguese merchants continued to work in the Congo-Angola area on the west coast of Africa and crossed the Atlantic for another century and a half I dominated slave trade.
It is estimated that between 16 and 12 million Africans engaged in the Atlantic slave trade have arrived in the New World between the 16th and the 19th century. The first Atlantic system refers to the Portuguese merchants who dominated the West African slave trade in the 16th century - New World colonies and importers of Africa - Spain and Portugal. Atlantic slave trade was done throughout the Atlantic, mainly from the 16th century to the 19th century. The majority of the slaves for the New World were Africans from the Midwest of the African continent and were sold to European slave merchants transferred from the African tribes to North American and South American colonies. Most contemporary historians estimate that between 4 million and 12 million Africans came to the New World between the 16th and 19th centuries.
