How did slave-owners shape Britain?

Open navigator

1. An uncomfortable truth

In 1833, Britain emancipated its enslaved people and raised the equivalent of £17bn in compensation money. But that money wasn't paid to the enslaved people – it was given to Britain's slave-owners for 'loss of human property.'

It was the largest state-sponsored pay-out in British history before the banking crisis in 2008. Taxpayer's money went straight into the pockets of people who had already profited from a cruel and inhumane business – the transatlantic slave trade.

Find out who Britain's slave-owners were and how their actions still impact our lives today.

2. Who were they?

The Slave Compensation Commission was set up to process the claims for compensation – 46,000 in all. Its records uncover how deeply slave-ownership had infiltrated 19th Century society and reveal many of us could have connections to the Britain’s slave-owning past.

Middle class Britons

Slave-ownership wasn't confined to the upper classes: an enslaved person was considered a sound investment. In 1833, middle class people including clergymen, naval personnel and people who had returned from the colonies were all slave-owners. Some purchased enslaved people, others acquired them through inheritance or marriage. Their value was based on skills, gender, age, health and the profitability of the plantation where they worked.


It was unusual for women to hold large financial assets, but they made up 25% of compensation claimants in Britain. When they were widowed, many women inherited enslaved people and relied solely on them as assets for their income. Some of the most urgent pleas for compensation came from widows, such as Hannah Barnes in Devon: "Myself, my daughter and her children are entirely dependent for support on what we receive from [my late husband's] estate... I am much in want of money."

Mixed-race Britons

Perhaps most surprisingly, the records detail a number of children born to plantation owners and enslaved women who inherited their father's slaves. A striking example is politician John Stewart, the son of a slave-owner and one of the first ethnic minority MPs. He inherited his father's sugar plantations in the West Indies and received considerable compensation for the enslaved people there. He spoke in parliament on several occasions in defence of slavery.

It’s almost impossible to avoid the legacies of the slave trade. Click below to reveal how slavery has shaped our daily lives:


Some of the wealthiest slave-owning families invested in the development of railway networks.

Dozens of these railway lines are still in use today, including the Grand Junction, now part of the West Coast Main Line.


The slave trade relied on systems of credit and insurance, leading to the development of London's financial industries.

High street banks RBS, Barclays and Lloyds were formed when smaller local banks, many in port-towns and cities where they financed slavery, were consolidated.


Brits developed a taste for a new variety of foods from across the Empire, including tea, coffee and chocolate.

The market for sugar grown on slave plantations boomed. Sugar consumption doubled between 1690 and 1740 and quickly became a staple of the British diet.


A number of slave-owners were trustees, patrons or donors to some of Britain's most cherished cultural institutions.
