The Slavery Abolition Act of 1833 freed enslaved people across the British Empire. It came into force on 1 August 1834 and applied to all British territories including the Caribbean colonies. It was a profound moral achievement and one of the most significant pieces of legislation Parliament has ever passed.
The Act freed approximately 800,000 enslaved people. It did not do so immediately in all cases: many were subjected to a period of “apprenticeship” in which they continued to work for their former owners, ostensibly to allow a transition period. This apprenticeship system was widely abused and was abolished in 1838 following continued campaigning.
The Act included a provision for compensating slave owners for the “loss” of their enslaved property. Twenty million pounds was paid, which was roughly 40 percent of the total government expenditure at the time and required the government to take out a loan that was not finally paid off until 2015. The enslaved people themselves received nothing.
The compensation provision is rightly criticised. It was deeply unjust that the people freed received no compensation for years of forced labour, while the people who had exploited them were paid to accept their freedom. This injustice is real and should not be minimised.
But the Act itself, and the political will it represented, was genuine. Britain chose to free 800,000 people at enormous financial cost to the state. That choice was not inevitable. Most other slave-holding nations did not make it for decades, and some never did voluntarily. The United States required a civil war. Brazil abolished slavery only in 1888. Cuba not until 1886.
