The British slave trade has been laid bare by a new register documenting over 10,500 investors who profited from the trafficking of enslaved Africans. The Register of British Slave Traders, a three-year project by specialist historians, reveals the extensive involvement of monarchs, MPs, and merchants in this brutal trade from the 1560s to abolition in 1807.
The Register of British Slave Traders: A Comprehensive Account
Led by Prof William Pettigrew of King's College London, the project provides biographical details for as many investors as possible, building the most comprehensive picture yet of those who perpetrated the enslavement of African people. The register documents the investors in Britain's near 250-year transatlantic slave trade, from the first traffickers in the 1560s to abolition in 1807.
Britain's trafficking operations, including royal companies led by kings and later a rush of entrepreneurs in Bristol, Liverpool, and other port cities, violently transported more than 3 million enslaved African men, women, and children to colonial plantations in the Americas and Caribbean.
Key Findings: Monarchy, Parliament, and Business Elites
The register reveals the relentless involvement of the British monarchy, parliament, and financial and business elites. The church played a role in legitimising the trade, and investors' wealth was woven deep into the country's fabric, funding hospitals, schools, welfare organisations, the arts, and science.
Notable Investors and Their Legacies
Among the investors were prominent figures such as King Charles II, who was a shareholder in the Royal African Company, and numerous MPs who voted to protect the trade. The wealth generated funded institutions that still exist today, including schools and hospitals.
