How did the trade in African slaves begin?

The slave trade across the Atlantic began in the 15th century. This stage was the next significant change in the life of Africans; previously making up a small part of the slaves in the world, by the 1800s they began to constitute the vast majority. In a short time, the slave trade has evolved from an insignificant sector of the economy to its prevailing component, and the use of slave labor on plantations has become the basis for the prosperity of many communities. Among other things, the Atlantic slave trade has changed the traditional distribution of forms of slavery.
The first Europeans to arrive on the Guinean coast were the Portuguese. The first deal to buy slaves took place in 1441. In the sixteenth century, the Portuguese, who settled on the island of Sao Tome, began using Negro slaves to cultivate sugar plantations, as the climate of the island was difficult for Europeans. With the discovery of America, the European settlement of San Jorge da Mina became an important center for sending slaves to the New World.
In America, the first Europeans to start using the labor of African slaves were the Spaniards, who settled on the islands of Cuba and Haiti. First, slaves arrived in the New World in 1501. The Atlantic slave trade reached its peak at the end of the 18th century. The inhabitants of the internal regions of West Africa were enslaved, sending special expeditions after them. The need for slaves due to the growing European colonies was so great that in the west of Africa whole empires arose due to the slave trade, including Oyo and the Kingdom of Benin.
