The Atlantic slave trade
What was the Atlantic slave trade?
The Atlantic slave trade or triangular trade involved the forced enslavement of many millions of Africans and their transport to the Americas, where they were made to work without wages in often inhumane conditions.
The trade was at its height during the 18th century when the British were the most active trading nation.
The cost of the slave trade in terms of human suffering can not be calculated.
Top 10 facts
- Slavery had existed for many years before the Atlantic slave trade commenced. The first known written law code – that of Hammurabi, dating from around 1760 BC – makes references to slaves.
- The first Europeans to enter into and profit from the slave trade in Africa were the Portuguese who began trading in the 15th century.
- African kings and merchants sold captured enemies or criminals to the European traders. Sometimes they had to sell slaves or risk being taken captive themselves.
- Approximately 12 million people were enslaved as a result of the Atlantic slave trade.
- The journey between Africa and the Americas, the so-called middle passage, took an average of seven weeks.
- Nearly 40% of people taken in slavery came from West Central Africa – the Republic of Congo, the Democratic Republic of Congo and Angola.
- Approximately 15% of slaves died whilst being transported to the Americas.
- Slaves were often captured inland and were marched for many weeks to reach the coast. There they were imprisoned in forts called factories awaiting shipping across the Atlantic.
- Slaves were tightly packed on board ships which could carry between 350 and 600 people, with as little as 4ft space. The unsanitary conditions led to the spread of disease and many slaves attempted to starve themselves or became very depressed. Some tried to jump overboard.

Slavery is where one person is owned by another. A slave is treated as if he or she were a piece of property and is forced to work for nothing for their owners. Slavery has probably existed throughout human history and been practised by many different civilisations.
Slavery in Africa existed before the arrival of Europeans but the Atlantic slave trade changed the scale of the trade and the way it was conducted. Over the centuries up to 12 million African people were enslaved and transported to the Americas. The majority (48%) went to the Caribbean islands, with 41% going to Brazil and 5% to North America. These slaves were chattel slaves which meant that their children were also slaves.
The Atlantic slave trade arose because Europeans were keen to make money from the newly discovered territories of the Americas. The native Indian population had been very much reduced and in some places almost wiped out by the Europeans and the survivors proved unsuited to the heavy labour they required. The transport of slaves from Africa seemed to provide the profit-hungry Europeans with an endless supply of labour.
The trade in slaves was called the triangular trade because it had three stages. Manufactured goods from Europe such as blankets, beads and guns were taken to Africa where they were exchanged for slaves. The transport of slaves from Africa to the Americas was known as the middle passage. Finally raw material and goods produced as a result of slave labour such as cotton, sugar, rum and tobacco from the Americas were brought back to Europe.
The Committee for the Abolition of the Slave trade was led by William Wilberforce, Granville Sharp and Thomas Clarkson. Although the British took a leading role in abolishing the trade it should not be forgotten that for many years Britain had been the most active slave-trading nation of all. Many people made a lot of money from the trade and cities such as Bristol, London and Liverpool grew wealthy as a result of it.
