Triangle trade: The "black triangle trade" began in the16th century, that is, the slave trade. European slave traders set out from their own countries and loaded salt, cloth, rum and so on. In Africa, they were turned into slaves and crossed the Atlantic along the so-called "central route". In America, they were turned into plantation products such as sugar, tobacco and rice, and gold, silver and industrial raw materials returned.

In western Europe, near the Gulf of Guinea in Africa and between the West Indies in America, the route is roughly triangular. Because the trafficked people are black, it is also called "black triangle trade", which lasted for 300 years.

Under the historical trend of capitalist development and favorable geographical conditions, the "black triangle trade" has been carried out smoothly for hundreds of years, while Europe and the United States have accumulated rich original capital.

Development process:

At that time, capitalism in European colonial countries developed rapidly, and a large number of products decided that they could be exchanged for blacks. Slave ship came to Africa with ocean currents.

The first is the canary cold current, which is located on the northwest coast of Africa, from about 45 degrees north latitude to about 15 degrees north latitude and belongs to compensation current.

The second is the Guinea Warm Current, which flows along the coast of the Gulf of Guinea in Africa and is also the compensation current.

After the slave traders arrived in Africa, they exchanged low-value goods with the chiefs of black tribes in exchange for young and strong blacks. At that time, the black tribes and their tribal leaders, who were still in a barbaric and ignorant state, were bought by slave traders like commodities under the influence of slave traders.
