The idea
Abolition was not one person's achievement. Clarkson supplied evidence and organisation: he gathered testimony, statistics and cargo manifests, toured the country, and helped found the committee that coordinated petitions. Wilberforce supplied the parliamentary voice, repeatedly introducing bills and steering debate until the 1807 Act ended British participation in the slave trade. Equiano supplied testimony and persuasion: his narrative and speaking tours made the Middle Passage vivid to readers who would never see it. Assess significance by asking what each could do that others could not, and how their roles complemented one another.
What earns the marks
- Explains Clarkson's contribution as evidence-gathering, investigation of ships and cargoes, and nationwide organisation of the abolition campaign.
- Explains Wilberforce's contribution as sustained parliamentary leadership, repeated motions and management of the bill that became the 1807 Act.
- Explains Equiano's contribution as first-hand testimony, published narrative and public speaking that shaped opinion.
- Judges relative significance by function: evidence, legislation and persuasion were different but interdependent roles.
- Uses specific evidence, such as the 1807 Act or the work of the abolition committee, to support the judgement.
Common mistakes and how to put them right
Crediting one individual with ending the slave trade alone.
Put it right by showing how evidence, parliamentary pressure and public persuasion combined.
Treating Equiano only as a victim rather than as an active campaigner.
Put it right by discussing his narrative and speaking as deliberate political action.
Assuming Wilberforce acted without organised support.
Put it right by linking his bills to the committee, petitions and public campaigning.
Exam tips
- Anchor each individual to a distinct function before comparing their significance.
- Use precise dates and measures, such as the 1807 Act, rather than vague claims about reform.
- Reach a clear relative judgement instead of listing three separate biographies.

Listen
Abolition was not one person's achievement. Clarkson supplied evidence and organisation: he gathered testimony, statistics and cargo manifests, toured the country, and helped found the committee that coordinated petitions. Wilberforce supplied the parliamentary voice, repeatedly introducing bills and steering debate until the 1807 Act ended British participation in the slave trade. Equiano supplied testimony and persuasion: his narrative and speaking tours made the Middle Passage vivid to readers who would never see it. Assess significance by asking what each could do that others could not, and how their roles complemented one another. A strong answer earns marks for these points.

Between c1785 and 1807, British abolition of the slave trade was not one person's achievement. It combined evidence, parliamentary pressure and public persuasion, with different campaigners doing different jobs. Think of the campaign as three functions. Clarkson supplied evidence and organisation. Wilberforce supplied the parliamentary voice. Equiano supplied first-hand testimony and persuasion. Their roles complemented one another rather than competing as separate biographies. Thomas Clarkson gathered testimony, statistics and cargo manifests. He toured the country and helped found the committee that coordinated petitions. This gave abolitionists a shared evidence base and a national organisation, not just a moral slogan. William Wilberforce repeatedly introduced bills and steered debate until the 1807 Act ended British participation in the slave trade. Olaudah Equiano's narrative and speaking tours made the Middle Passage vivid to readers who would never see it. Both turned campaign material into pressure. To judge relative significance, ask what each person could do that others could not. Clarkson could gather evidence; Wilberforce could introduce bills; Equiano could testify from experience. Pause briefly: which function was indispensable in 1807? The stronger answer links evidence, legislation and persuasion, then judges their interdependence. Avoid crediting one individual with ending the slave trade alone. Avoid treating Equiano only as a victim; his narrative and speaking were deliberate political action. Avoid assuming Wilberforce acted without organised support; his bills rested on the committee, petitions and public campaigning. So abolition is best explained by combining functions: Clarkson's evidence and organisation, Wilberforce's parliamentary leadership, and Equiano's testimony and persuasion, culminating in the 1807 Act. Use precise evidence and a clear relative judgement about how these roles depended on one another.
