This study pack is about the transatlantic slave trade, enslavement in the Americas, resistance by enslaved people, and abolition.
Between the 1500s and 1800s, millions of African people were forcibly taken across the Atlantic Ocean. They were sold and made to work, mainly on plantations in the Caribbean, North America and South America. This system was not accidental. It was organised for profit by European empires, merchants, shipowners, plantation owners and investors.
Britain became deeply involved. British ships carried goods to Africa, transported enslaved Africans across the Atlantic, and brought plantation products such as sugar, tobacco and cotton back to British ports. Cities including Liverpool, Bristol and London grew wealthy through this trade and through connected industries.
The history of transatlantic slavery is also a history of African societies, survival, family, culture, resistance and campaigning. Enslaved people were not passive victims. They resisted in many ways, from preserving language, religion and community, to running away, slowing work, rebelling and giving testimony. Their actions were central to the weakening and eventual ending of slavery.
Abolition means ending a system by law. In Britain, Parliament abolished the slave trade in 1807, but this did not end slavery itself. Slavery in most British colonies was abolished by law in 1833, with freedom coming in stages from 1834 and apprenticeship ending in 1838. Enslavers received large compensation payments. Enslaved people received no compensation for their stolen freedom, labour, family life or suffering.
This topic needs careful language. It is better to say enslaved people rather than slaves because enslavement was something done to people. It was not their identity.

The slave trade grew over several centuries. It was linked to European colonisation, plantation farming and demand for goods such as sugar. Abolition also took time. It was caused by many factors, including resistance by enslaved people, Black testimony, religious and moral campaigns, economic arguments, political pressure and events such as the Haitian Revolution.
Africa was not one single place with one culture. It was, and is, a huge continent with many different societies, languages, religions, governments and economies.
Before and during the transatlantic slave trade, West and Central Africa included:
Some African rulers and merchants became involved in selling captives. This happened for reasons including warfare, political rivalry, profit and pressure from European demand. However, European empires created and expanded the Atlantic plantation system that made the trade grow to such a large scale.
It is important not to blame “Africa” as a whole. African societies were varied. Some people profited, many resisted, and millions were harmed.
The transatlantic slave trade developed because European empires wanted labour for colonies in the Americas. After colonisation, Europeans seized land and created plantations. Many Indigenous people in the Americas died because of violence, forced labour and diseases brought by Europeans. Europeans then increasingly turned to enslaved African labour.
Key causes included:
The system grew because it connected many parts of the economy. It was not only plantation owners who profited. People who made chains, guns, textiles, ships, barrels and sugar-processing equipment could also benefit.
Triangular trade is a simplified way of explaining trade routes between Europe, Africa and the Americas. Not every ship followed a perfect triangle, but the model helps show how the system connected places and profits.
Europe | manufactured goods: textiles, metal goods, guns, alcohol v West and Central Africa | enslaved people forced onto ships v Americas and Caribbean | sugar, tobacco, cotton, coffee, rum, profits v Europe
The Middle Passage was the forced sea journey from Africa to the Americas. Enslaved Africans were packed onto ships in dangerous and dehumanising conditions. Many died from disease, violence, hunger, thirst or despair. Survivors reached the Americas and were sold.
Historians use shipping records, court cases, testimony and plantation records to study the Middle Passage. These sources show that shipowners often treated people as cargo because they saw them as property. However, testimony and resistance also show the humanity, fear, courage and agency of those forced onto ships.
Resistance during the Middle Passage included:
After arrival, enslaved people were often sold at auctions or in private sales. Families could be separated. People were forced onto plantations, into homes, docks, workshops, mines or other labour systems.
In the British Caribbean, sugar plantations were especially important. Sugar was difficult and dangerous to produce. It involved planting, cutting cane, crushing it, boiling juice, and preparing sugar for export. Plantation owners used violence and strict rules to control workers. Enslaved people had little legal protection because colonial laws treated them as property.
Plantation slavery depended on forced labour and control. Enslavers used laws, punishment, surveillance and racist ideas to maintain power. They also tried to control movement, family life, religion and education.
However, enslaved communities found ways to build family networks, worship, share knowledge, grow food, tell stories, practise music and preserve cultural traditions. These actions mattered because they helped people survive and resist the attempt to reduce them to property.
Britain was not a minor participant. By the 1700s, British merchants and ships were heavily involved in the transatlantic slave trade and plantation economy.
Important British ports included:
British industries connected to slavery included:
This does not mean every person in Britain directly owned a plantation or ship. It means the economy, ports and consumer habits were linked to slavery in many ways.
Enslaved people resisted slavery from the beginning. Resistance could be large or small, public or hidden.
Types of resistance included:
Resistance mattered because it made slavery harder to maintain. It also showed that enslaved people challenged the system themselves, rather than waiting to be rescued.
Abolition in Britain was supported by many people with different roles.
Olaudah Equiano was an African writer and abolitionist. His published autobiography described his life, enslavement and freedom. His testimony helped British readers understand the cruelty of the trade.
Ottobah Cugoano was an African abolitionist writer. He argued strongly against slavery and challenged the moral and religious excuses used by enslavers.
Mary Prince was born into slavery in Bermuda and later gave testimony published in Britain. Her account helped campaigners expose the violence of slavery in the British colonies.
Thomas Clarkson collected evidence against the slave trade. He gathered objects, diagrams and testimony that campaigners used in speeches and publications.
Granville Sharp supported legal cases involving Black people in Britain and became an important abolitionist organiser.
William Wilberforce was an MP who presented abolitionist arguments in Parliament. He was significant, but abolition did not happen because of him alone.
A strong answer about abolition should include Black campaigners, enslaved resistance, women campaigners, religious groups, workers, consumers, politicians and international events.
The Haitian Revolution began in 1791 in the French colony of Saint-Domingue, now Haiti. Saint-Domingue was one of the richest plantation colonies in the world, producing sugar and coffee through brutal slavery.
Enslaved people rebelled against slavery and colonial rule. Over years of war, they defeated French, British and Spanish forces. In 1804, Haiti became independent.
The Haitian Revolution was significant because:
Some British abolitionists used Haiti as evidence that slavery caused violence and instability. Some enslavers used it to argue against reform because they feared rebellion. This shows how the same event could be interpreted differently.
It is important to separate two different legal changes.
The Abolition of the Slave Trade Act 1807 made it illegal for British ships and British subjects to trade enslaved Africans. It did not free people already enslaved in British colonies.
The Slavery Abolition Act 1833 abolished slavery in most British colonies. It came into effect in 1834. However, many formerly enslaved people were forced into a system called apprenticeship, which kept them working for former enslavers. Apprenticeship ended early in 1838 after criticism and resistance.
The 1833 Act included compensation for enslavers. The British government borrowed a huge sum, £20 million, to pay people who claimed they had lost “property”. This was about 40% of government spending at the time. Enslaved people received no compensation.
This matters because it shows that abolition did not immediately create equality. Former enslavers often kept land and wealth. Formerly enslaved people had to fight for wages, land, education, family stability and political rights.

Historians use many kinds of evidence for this topic. Each type has strengths and limitations.
This is an invented, historically plausible extract based on the kind of testimony given by formerly enslaved people. It is not a real quotation.
“When I was taken to the estate, the bell marked the hours of work. We cut cane under the sun and carried it to the mill. At night, people spoke quietly of home, family and how to keep courage. Some hid food for children. Some damaged tools. Some prayed that freedom would come.”

Questions:
An interpretation is a way of explaining the past. Interpretations can differ because historians ask different questions, use different evidence or write in different periods.
This interpretation argues that abolition happened mainly because campaigners persuaded Parliament. It highlights people such as Thomas Clarkson and William Wilberforce, petitions, speeches, pamphlets and boycotts.
Strength:
Limitation:
This interpretation argues that slavery was weakened by the actions of enslaved people themselves. It highlights revolts, escape, everyday resistance, testimony and the Haitian Revolution.
Strength:
Limitation:
This interpretation argues that slavery and the slave trade were challenged when some people believed they were becoming less profitable, risky or less useful to British economic interests.
Strength:
Limitation:
A strong KS3 answer should avoid one-cause explanations. Abolition happened because of a combination of:
| Cause | How it helped create or maintain slavery | Consequence |
|---|---|---|
| European colonisation | Created plantations in the Americas | High demand for forced labour |
| Demand for sugar | Made plantation profits attractive | Expansion of Caribbean slavery |
| Racist ideas | Used to justify treating people as property | Long-term racism after abolition |
| British port wealth | Merchants invested in ships and goods | Cities grew through slave-linked trade |
| State support | Laws and companies protected trade | Slavery became part of empire |
| Enslaved resistance | Made slavery harder to control | Increased pressure and fear |
| Abolition campaigning | Spread evidence and moral arguments | Public and parliamentary pressure |
| Type of resistance | Example | Why it mattered |
|---|---|---|
| Everyday resistance | Slowing work, breaking tools, hiding food | Disrupted plantation control |
| Cultural survival | Keeping songs, beliefs, stories and family practices | Protected identity and community |
| Escape | Running away to towns, forests or independent communities | Challenged enslavers’ power |
| Revolt | Haitian Revolution, Jamaica rebellion | Showed slavery could be overthrown |
| Testimony | Equiano and Mary Prince | Gave evidence to abolition campaigns |
| Boycott support | Consumers refusing slave-grown sugar | Linked ordinary people to protest |
| Cause | Evidence | Possible ranking |
|---|---|---|
| Enslaved resistance | Haiti, Jamaica, everyday resistance | Very high |
| Black abolitionist testimony | Equiano, Cugoano, Prince | Very high |
| Parliamentary campaign | Wilberforce, debates, laws | High |
| Public pressure | Petitions, meetings, sugar boycotts | High |
| Religious and moral arguments | Quakers, evangelicals, humanitarian arguments | High |
| Economic change | Debates over profit and empire | Medium to high |
| Individual white campaigners | Clarkson, Sharp, Wilberforce | Important, but not enough alone |

More emphasis on enslaved people’s action
A balanced argument can place evidence across the whole scale.
Mistake: Saying “slaves” as if it was a natural identity.
Better: use “enslaved people” to show slavery was forced upon them.
Mistake: Thinking Africa was simple or undeveloped before the slave trade.
Better: remember African societies were diverse, with kingdoms, trade, towns and skilled work.
Mistake: Saying Britain ended slavery in 1807.
Better: Britain abolished the slave trade in 1807. Slavery in most British colonies was abolished by the 1833 Act, with freedom beginning in 1834 and apprenticeship ending in 1838.
Mistake: Giving all credit to William Wilberforce.
Better: include enslaved resistance, Black campaigners, women campaigners, boycotts, petitions and other abolitionists.
Mistake: Describing enslaved people only as victims.
Better: explain suffering and control, but also agency, resistance, survival and culture.
Mistake: Ignoring British economic involvement.
Better: include ports, merchants, consumers, factories, banks, insurers and plantation goods.
Mistake: Treating abolition as immediate equality.
Better: explain compensation to enslavers, no compensation to enslaved people, apprenticeship and long-term racism.
Mistake: Using sources without checking provenance.
Better: ask who made the source, why, for whom, and what it can and cannot tell us.

Good answers should include accurate knowledge and explanation. For example:
The transatlantic slave trade developed because European empires wanted labour for colonies in the Americas. After Europeans colonised land, they created plantations to grow crops such as sugar, tobacco, cotton and coffee. These crops could be sold in Europe for profit, so plantation owners wanted a large labour force that they could control.
Another reason was profit. British and other European merchants made money by selling manufactured goods in Africa, transporting enslaved Africans across the Atlantic, and importing plantation goods back to Europe. Ports such as Liverpool, Bristol and London became connected to this trade. Industries such as shipbuilding, banking, insurance and sugar refining also benefited.
Racist ideas also helped the system develop. Europeans used false ideas about African people to justify enslavement. These ideas did not cause the trade alone, but they helped make cruelty seem acceptable to people who profited from it.
Overall, the trade developed because empire, profit, plantation demand and racist thinking worked together.
Testimony is very useful because it can show the experiences and voices of people who were enslaved. Plantation records often describe people as property or labour, but testimony can reveal feelings, family life, violence, survival and resistance. For example, accounts by people such as Olaudah Equiano and Mary Prince helped readers understand the cruelty of slavery and the slave trade.
Testimony is also useful for studying abolition because campaigners used it as evidence. It helped challenge enslavers who claimed slavery was mild or necessary. Testimony could make distant events in the Caribbean or on slave ships more understandable to British readers.
However, testimony also has limitations. One person’s experience cannot represent everyone. Published testimony might have been edited for a particular audience or campaign purpose. Historians should compare it with other evidence, such as ship records, court cases, plantation accounts and abolitionist material.
Overall, testimony is extremely valuable, especially because it helps recover enslaved people’s voices, but it should be used carefully alongside other sources.
The British slave trade was abolished in 1807 because of several connected causes. One important cause was campaigning. Abolitionists organised petitions, public meetings, pamphlets and boycotts of slave-grown sugar. Thomas Clarkson collected evidence, and William Wilberforce argued in Parliament. This helped make abolition a national political issue.
Black abolitionists and testimony were also very important. Olaudah Equiano and Ottobah Cugoano used their writing and personal experience to challenge slavery. Their evidence made it harder for supporters of the trade to deny its cruelty.
Enslaved resistance was another major cause. Revolts, escape and everyday resistance showed that enslaved people rejected slavery. The Haitian Revolution, beginning in 1791, showed that enslaved people could destroy slavery in a major colony. This made the slave system seem more dangerous and unstable.
Economic and imperial factors also mattered. Some people argued that the slave trade was becoming less useful or that Britain could gain power by stopping rival nations’ trade. These arguments worked alongside moral pressure.
The slave trade was not abolished because of one person. It ended because resistance, testimony, public campaigning, politics and economic factors combined.
Enslaved people’s resistance was highly significant in bringing about abolition. Resistance happened in many forms. Everyday resistance, such as slowing work, hiding food or damaging tools, weakened plantation control. Cultural survival also mattered because it protected identity and community against a system designed to dehumanise people.
Open rebellion was also important. The Haitian Revolution was one of the most significant events in Atlantic history because enslaved people fought successfully against slavery and colonial rule. It proved that slavery could be overthrown by enslaved people themselves. Later rebellions, including the Jamaica rebellion of 1831-1832, increased pressure on Britain to end slavery in its colonies.
Resistance also supported abolition through testimony. Formerly enslaved people such as Olaudah Equiano and Mary Prince gave evidence that campaigners used in Britain. Their words challenged pro-slavery arguments and helped persuade readers.
However, resistance was not the only cause. Parliamentary action, petitions, boycotts, religious campaigns and economic arguments were also needed to change British law. Without political action, the 1807 and 1833 Acts would not have passed.
Overall, enslaved resistance was one of the most significant causes because it challenged slavery directly and showed enslaved people’s agency. A balanced answer should place it alongside campaigning and law-making, not below them.
I partly agree that William Wilberforce was important, but I do not agree that he was the main reason abolition happened. Wilberforce was significant because he was an MP who argued against the slave trade in Parliament. He helped bring abolitionist evidence into political debate and supported laws against the trade.
However, abolition depended on many other people and causes. Thomas Clarkson collected evidence, Granville Sharp supported legal cases, and many ordinary people signed petitions or boycotted slave-grown sugar. Women also played an important role in local campaigning, even though they could not vote for MPs.
Black abolitionists were especially important. Olaudah Equiano, Ottobah Cugoano and Mary Prince gave powerful testimony about enslavement and the slave trade. Their experiences challenged the lies told by enslavers.
Most importantly, enslaved people resisted slavery themselves. Everyday resistance, escape, revolt and the Haitian Revolution all weakened the system and showed that enslaved people fought for their own freedom.
Overall, Wilberforce was an important parliamentary campaigner, but abolition happened because of a wider movement and because enslaved people resisted slavery. Saying it was mainly due to him gives too much credit to one person and too little to others.
