The Register of British Slave-Traders has shattered the myth of Britain's role in profiting from enslavement, revealing over 13,000 individuals who invested in the trafficking of more than three million Africans between 1563 and 1807. This comprehensive database, reported exclusively by the Guardian, exposes a wide range of investors from ordinary citizens to the monarchy itself.
Uncovering the Investors Behind the Slave Trade
The Register, compiled by the Guardian's Legacies of Enslavement team, lists men and women from all walks of life who profited from the transatlantic slave trade. From provincial towns to the royal court, the evidence shows that slavery was not just a national enterprise but a deeply personal one for thousands of Britons.
Among the most notable figures are Queen Elizabeth I and her court, who invested in John Hawkins's 1563 mission and subsequent voyages. They provided Hawkins with money and ships, including the royal ship Jesus of Lübeck, which trafficked 359 Africans to the Americas in 1568. Elizabeth's successors—James I, Charles I, Charles II, James II, William III, Queen Anne, George I, and George II—were major investors, shareholders, and directors in the state-sponsored Company of Royal Adventurers Trading in Africa, the Royal African Company, and the South Sea Company.
Other investors included famed philosopher John Locke, who ironically championed natural rights, and Tobias Rustat, a University of Cambridge benefactor whose bust still stands in Jesus College Chapel despite efforts to remove it.
The Financial Impact of Slavery on Britain
The profits from slavery flowed into every corner of British society, funding infrastructure, institutions, and individual fortunes. The Register reveals that many ordinary people, not just the elite, had a financial stake in the trade.

| Investor | Role | Notable Contribution |
|---|---|---|
| Queen Elizabeth I | Monarch | Provided ships and funds for John Hawkins |
| John Locke | Philosopher | Invested in slave-trading companies |
| Tobias Rustat | University benefactor | Invested in Royal African Company |
| Ordinary citizens | Various | Small-scale investments in voyages |
This data underscores how deeply embedded slavery was in Britain's financial system, challenging the notion that only a few benefited.
