Effects on African societies

West African slavery

Slavery had existed in West Africa long before the Europeans arrived there. Prisoners of war captured in battles between rival kingdoms or tribes were commonly kept as slaves. These slaves could be put to work in mines or even put to death in religious rituals.

European slave traders seldom captured African slaves by themselves. The terrain was too difficult and the native kingdoms often too strong for a handful of white slavers to fight. Most slaves were sold to the Europeans by other Africans.

African states such as Ashanti (in modern day-Ghana) traded their slaves in exchange for goods – such as cloth, alcohol and guns. They then used their new resources to become more powerful and to fight wars against their neighbours in order to capture more slaves.

The Kingdom of Dahomey

The Kings of Dahomey sent raiding parties into neighbouring lands with the sole purpose of capturing slaves. These slaves would then be sold to the Europeans. By 1750, King Tegbesu of Dahomey made £250,000 a year selling Africans into slavery. Under his reign, slavery became the largest part of the Kingdom’s income.

The demand for slaves soon became so great that prisoners of war were not enough. Raiding parties were organised to kidnap young Africans from rival tribes.

It has been estimated that 326,000 slaves were taken from the Bight of Bonny (in modern-day Nigeria) between 1780 and 1800. In 1790, Alexander Falconbridge, a slave-ship surgeon, reported that the goods used to buy slaves from this area included guns, gunpowder, textiles, iron bars and brandy. Other popular items traded included copper, brass and pewter goods.

The area around the Bight of Benin and the Bight of Bonny became known as the Slave Coast.

Lasting effects on Africa

Some historians believe that the slave trade ruined Africa because of the constant wars and the loss of millions of strong, young people. Africa fell behind the rest of the world. Some historians think that this is why Africa was colonised by European countries in the 19th century.

Other historians draw attention to the benefits of the slave trade for African rulers - the ruling elite of native African Kingdoms prospered from the slave trade. When the British abolished the slave trade in 1807, the King of Bonny wrote to Parliament to complain.
