British Abolition Act 1833: Britain Ends Slavery Across Its Empire

Britain's Slavery Abolition Act received Royal Assent on August 28, 1833, abolishing slavery throughout the British Empire, approximately 800,000 enslaved people freed, primarily in the Caribbean. The Act granted slaveholders £20 million in compensation (roughly £2 billion in 2024 terms) and imposed a four to six year 'apprenticeship' period on freed people. No compensation was paid to the enslaved. The British precedent made American slavery increasingly anomalous among Western nations and gave abolitionists a powerful argument: if Britain with its powerful planter lobby could abolish slavery, so could the United States. American slaveholders responded by intensifying proslavery ideology claiming slavery was a positive good.
