Slave trade in Africa

The African slave trade by Europeans began in 1441 when Portuguese Antam Gonzalves presented an African man and woman (who were Arabs rather than blacks) abducted on the Western Sahara coast to the Crown Prince of Portugal.
 

It is recorded that 927 slaves were abducted to Portugal between 1441 and 1448, all of whom were Arabs rather than blacks.
In fact, slave hunting by whites such as Portuguese and British has not been carried out except in the early days.
It was the local influential people (that is, blacks) and Arab merchants who actually collected the slaves and sold them to European traders.

In the 1440s, the black kingdoms of Africa fought each other in tribal struggles, trading in the form of selling the people of other tribes obtained from slave hunting to Portugal.
The Portuguese then carried the purchased slaves to the West Indies and sold them as the labor needed for plantations for sugar production that were developing throughout the Caribbean.

In the 1450s, Guinea Gulf countries such as Senegal and Benin and local forces such as Congo began selling prisoners of war and slaves under local institution to Portuguese merchants.
The people sold as slaves were originally slaves, prisoners of war, people who became tributes from their nations, debt slaves, criminals, etc., but in Congo etc., the purpose is to hunt slaves for sale to European traders. The expedition was frequently carried out.
 

The slave trade continued until the mid-1800s, but the African kingdoms of West Africa, such as Waida, Dahomey, and Senegambia, began to be enriched by this slave trade.
It is said that the number of black people who crossed the Atlantic Ocean in the slave trade for about three centuries is around 15 million.
 

The mortality rate of slaves in transit is 13%, and the mortality rate of slave ship sailors is 20-25%.
