By the end of the 17th century, European demand for African captives, particularly for the sugar plantations in the Americas, became so great that they could only be acquired by raiding and warfare.
The Asante (Ashanti people) Empire dominated the area known as the Gold Coast (Ghana) and grew wealthy by selling captives to European traders and fighting many wars to defend and expand their empire.
75% of African enslaved people were held near the rivers Luanda, Congo and Niger where diseases like malaria were common and many died in these holding ports due to the slave trade.
Europeans also brought with them deadly diseases, such as European strains of syphilis and smallpox, typhus and tuberculosis, to Africa during the slave trade.
Having fewer young healthy people to produce food due to the slave trade led to large areas of land being uncultivated, resulting in famine which increased the death toll.
History shows that slavery provoked a culture of political violence and disregard for human life which created attitudes of racism and contempt for Africans.
Today, more than 200 years after the abolition of slavery, ideas about the inferiority of Black Africans still remain in western society as witnessed by the Black Lives Matter campaign.
