Lesson Content/Board Summary

Early European Contact With Nigeria – The Trans-Atlantic Slave Trade

Nature and Organization of the Trans-Atlantic Slave Trade

The Trans-Atlantic slave trade was the trade in human beings between Africa, Europe, and the Americas from the 15th to the 19th century. Africans were captured, sold, and transported across the Atlantic Ocean mainly to work on plantations in the Americas.

The following are the main features of the Trans-Atlantic slave trade:

It involved the exchange of African slaves for European goods such as guns, mirrors, clothes, and spirits.
It formed part of the triangular trade between Europe, Africa, and the Americas.
Slaves were captured from different parts of Africa, especially West Africa, and taken to the coast for sale.
The trade was organized through middlemen who collected slaves from the hinterland.
European traders established trading posts along the Nigerian coast such as Lagos, Calabar, Bonny, and Brass.

Europeans That Came to Nigeria as Explorers and Traders

Several European nations participated in the Trans-Atlantic slave trade and had contact with Nigeria through exploration and trading activities.

They include:

The Portuguese – the first Europeans to arrive in Nigeria around 1472, trading mainly along the Niger Delta.
The British – dominated the trade later and established strong bases in Lagos and Calabar.
The Dutch – traded mainly in the coastal areas and competed with other Europeans.
The French and Spanish – also participated but were less dominant in Nigerian regions.

The Route of the Trade through the Atlantic Ocean (Lagos–Calabar)

The trade route followed a triangular pattern across the Atlantic Ocean connecting three continents – Europe, Africa, and America.

The following are the major routes of the Trans-Atlantic slave trade:

European ships left Europe loaded with goods such as guns, clothes, and spirits.
They sailed to African ports like Lagos and Calabar to exchange these goods for slaves.
The slaves were then transported across the Atlantic Ocean to the Americas in a journey called the Middle Passage.
In the Americas, the slaves were sold, and the ships were loaded with raw materials like sugar, tobacco, and cotton for the return journey to Europe.

Impact of the Atlantic Slave Trade

The Trans-Atlantic slave trade had great effects on both Africa and Europe.

The following are some of its impacts:

It led to loss of population in Africa due to continuous slave raids.
Many African communities became weak and disorganized.
It encouraged wars and insecurity among African states.
Traditional industries and agriculture declined in many areas.
It led to the rise of powerful kingdoms such as Oyo and Benin that participated in the trade.
European countries grew richer from the profits of the trade.
It created long-term hatred and mistrust between Africans and Europeans.

Abolition of the Atlantic Slave Trade

By the late 18th century, movements began in Europe to end the slave trade because of its cruelty and inhumanity.

The following are reasons and steps that led to the abolition:

The rise of humanitarian groups that opposed slavery.
The industrial revolution which made slave labour less profitable.
The influence of Christian missionaries who preached against slavery.
The British government passed laws to stop the trade, such as the Abolition Act of 1807.
In 1833, slavery itself was finally abolished in the British Empire.
British naval ships began to patrol African coasts to stop slave trading activities.
