The abolition campaign: the work of the campaigners and their methods, the arguments for and against abolition, the reasons opponents defended the trade, and the abolition of the British slave trade in 1807.

What this dot point is asking

This dot point covers the campaign to abolish the British slave trade and its success in 1807. The SQA British context requires you to know who the campaigners were and the methods they used, the arguments made for abolition, the reasons others defended the trade and opposed abolition, and the factors that finally brought about the 1807 Act. This is the conclusion of the topic, where moral campaigning, public pressure, the resistance of the enslaved and political change came together.

The dot point matters because it asks you to weigh competing causes, why abolition happened and why it was resisted, which makes it ideal for Explain questions. Note that the 1807 Act abolished the British slave trade (the buying and selling of people); the full abolition of slavery itself in British colonies came later. Questions are usually Explain (why the trade was abolished, or why abolition was opposed).

The answer

The British slave trade was abolished in 1807 after a long campaign. Campaigners, organised in an abolition society and supported by religious groups such as Quakers and evangelicals, gathered and publicised evidence of the trade's cruelty, especially the Middle Passage and the plantations. They used petitions, public meetings, pamphlets and a boycott of slave-grown sugar to turn public opinion against the trade. Former enslaved people and writers gave first-hand accounts that made the suffering real. Resistance and revolts in the colonies made the trade look dangerous and costly. In Parliament, persistent campaigning, associated above all with William Wilberforce, finally won enough support, and the trade was abolished in 1807. Abolition was fiercely opposed, however, by planters, merchants and trading ports who profited from the trade and argued it was vital to the economy.

The campaigners and their methods

The abolition movement was well organised. An anti-slavery society co-ordinated the campaign, and religious groups, especially Quakers and evangelical Christians, gave it moral energy by arguing that slavery was a sin. Campaigners collected evidence of the trade's cruelty and publicised it widely. They organised mass petitions to Parliament, held public meetings, produced pamphlets and images, and promoted a boycott of sugar produced by enslaved labour. The first-hand testimony of formerly enslaved people and writers made the abstract horror concrete for the British public.

The arguments for and against

Abolitionists argued on moral and religious grounds that the trade was cruel and sinful and that enslaved people were human beings with the same rights as others. Opponents defended the trade mainly on economic grounds: planters and merchants made large profits; ports such as Liverpool and Bristol depended on it for jobs and wealth; and defenders argued the trade was essential to Britain's economy, that abolition would cause ruin, and that rivals would simply take over if Britain withdrew.

Why the trade was abolished in 1807

Several factors combined. Years of campaigning had turned public opinion firmly against the trade. The moral and religious case gave the movement determination. The resistance and revolts of the enslaved made the trade appear dangerous and expensive to defend. Sustained pressure in Parliament, led by figures such as William Wilberforce, kept the issue alive through repeated defeats until, in 1807, enough votes were won to pass the Act abolishing the British slave trade.

Examples in context

An Explain question on why the trade was abolished links causes to effects: "campaigners publicised the cruelty, so opinion turned against the trade"; "religious groups argued slavery was sinful, which gave the movement moral force"; "petitions and boycotts pressured Parliament, so politicians felt the public mood"; "resistance made the trade seem costly, so its defence weakened"; "persistent campaigning by Wilberforce finally won the vote". For opposition: "planters and merchants made huge profits, so they fought to protect them"; "ports depended on the trade, which meant cities resisted"; "opponents claimed the economy needed it, so they warned of ruin".

Try this

Q1. Give two methods abolitionists used to campaign against the slave trade. [2 marks]

• What the marker wants. Any two of: mass petitions to Parliament; public meetings; pamphlets and images; a boycott of slave-grown sugar; publicising evidence and first-hand testimony.

Q2. Why did planters, merchants and ports oppose abolition? [2 marks]

• What the marker wants. Because they made large profits from the trade and depended on it for jobs and wealth, and they argued it was vital to Britain's economy, so they fought to protect their incomes.

Q3. What did the 1807 Act actually abolish? [1 mark]

• What the marker wants. The British slave trade, the buying, selling and transporting of enslaved people; the abolition of slavery itself in the colonies came later.
