Key facts and dates

Britain played a major part in the transatlantic slave trade during the 17th and 18th centuries, profiting from the forced labour of millions of Africans on plantations. Growing opposition eventually led to its abolition, marking a significant shift in attitudes towards human rights.

Timeline of key events

• 1492 – Spanish establish plantations in the West Indies, creating demand for African slaves.
• 1600s – British, Dutch, and French set up trade posts in Africa to supply slaves.
• 1700s – Britain dominates the transatlantic slave trade and owns plantations in the West Indies and America.
• 1791 – James Towne reports on African tribes capturing slaves for European traders.
• 1807 – Slave trade banned in the British Empire.
• 1833 – Keeping slaves banned in the British Empire, with gradual emancipation.

Britain's involvement in the transatlantic slave trade

Britain became heavily involved in the transatlantic slave trade from the 1600s, capturing and selling millions of Africans to work on plantations in the Americas. This trade was driven by the demand for cheap labour to produce valuable crops, and it expanded rapidly as European powers competed for control.

Early development of the slave trade

• Spanish influence - From 1492, the Spanish created plantations in the West Indies, relying on African slaves for labour-intensive work on crops like sugar.
• British entry - By the 1600s, British traders established posts along Africa's west coast, initially selling slaves to the Spanish before developing their own trade networks.
• Expansion in the 1700s - Britain took a leading role, dominating the trade and owning plantations in the West Indies and North America, where slaves grew profitable crops such as cotton, tobacco, and sugar.

The triangular trade system and conditions for slaves

The transatlantic slave trade operated through a system known as the triangular trade, which connected Britain, Africa, and the Americas in a cycle of exploitation. This involved transporting goods, enslaved people, and plantation products across the Atlantic, but the human cost was enormous due to brutal conditions.

Structure of the triangular trade

• Leg one - British ships left ports like Bristol or Liverpool loaded with cheap goods to trade in Africa.
• Leg two (Middle Passage) - Goods were exchanged for enslaved Africans, who were crammed onto ships, chained in rows, and forced to endure weeks of travel amid vomit, waste, and disease; around 1.8 million people died during these voyages out of approximately 12.5 million transported.
• Leg three - Surviving slaves were sold to plantation owners in the West Indies or North America, with ships returning to Britain carrying crops like sugar or cotton for sale.

Harsh conditions on ships and plantations

• On the ships - Enslaved people faced overcrowding, chains, and minimal food, leading to widespread death from illness, starvation, or mistreatment.
• On the plantations - Slaves worked extremely long hours without pay, growing crops for export; they suffered frequent beatings, and owners could kill them without consequence.

African tribes often captured slaves through wars or raids, selling prisoners to European traders at coastal posts, as reported by witnesses like James Towne in 1791.

Economic benefits of slavery to Britain

The slave trade brought significant wealth to Britain, boosting cities, industries, and investments. Profits from enslaved labour helped fuel economic growth, contributing to the country's rise as a global power during the 18th century.

Ways slavery supported Britain's economy

• Growth of ports - Cities like Bristol, Liverpool, Hull, and Lancaster expanded rapidly as trade hubs, becoming busy and wealthy from the influx of ships and goods.
• Wealth for traders - Individuals involved in trading slaves or plantation products became some of the richest people, reinvesting profits into banks and scientific developments.
• Boost to industries - Cheap cotton from slave plantations expanded Britain's textiles sector, which played a key role in the Industrial Revolution by providing raw materials for factories.

Opposition to slavery and key campaigners

As awareness grew of the horrific conditions faced by slaves, opposition mounted both on plantations and in Britain. Slaves resisted directly, while British campaigners used legal and political means to challenge the system, highlighting its inhumanity.

Forms of resistance by slaves

• Disruption on plantations - Slaves protested by breaking tools or destroying crops, which slowed production and frustrated owners.
• Escapes and risks - Some ran away, though this was dangerous, often leading to severe punishment or death if recaptured.

British campaigners against slavery

• William Wilberforce - A politician who dedicated his career to ending slavery, campaigning in Parliament until his death in 1833, just days after its ban.
• Granville Sharp - Fought legal battles in courts to challenge the rights of slave owners and protect escaped slaves in Britain.
• Olaudah Equiano - A former slave captured at age 11, who bought his freedom and published his autobiography, detailing experiences in Barbados and on ships; his book raised public support for abolition.

The abolition of the slave trade and slavery in the British Empire

Despite strong resistance from those profiting from slavery, sustained campaigns led to its gradual end in the British Empire. This marked a major victory for human rights, though the process was slow and involved compromises.

Steps towards abolition

• Ban on the slave trade (1807) - Parliament outlawed the buying and selling of slaves within the British Empire, halting the transatlantic trade.
• Ban on keeping slaves (1833) - Slavery itself was abolished; children under 6 were freed immediately, while older slaves transitioned through an apprenticeship period of six years for field workers and four years for other workers, during which they received minimal pay for work. The apprenticeship system was ended early in 1838.
• Challenges during abolition - Wealthy interests opposed the changes, as slavery had generated huge profits, but public pressure and moral arguments eventually prevailed.
