How enslavement became a state-backed operation in Britain is a question that the newly published Register of British Slave Traders helps answer. The register documents thousands of investors in Britain’s near 250-year trafficking of more than 3 million enslaved African people, revealing that the trade was not merely a private enterprise but a state-backed operation fully supported by both major political parties at the time: the Tories and Whigs, forerunners of today’s Conservatives and Liberal Democrats.
The Register of British Slave Traders: A Window into State-Backed Enslavement
The Register of British Slave Traders, compiled from extensive archival research, lists thousands of individuals who invested in the slave trade. Many Tory and Whig MPs were investors, and many also owned plantations. This data underscores that enslavement was a state-backed operation, with political elites deeply complicit. The register shows that the trade was not a marginal activity but a central pillar of Britain’s economy and political system.
Political Parties and Their Roles in Enslavement
When the abolition movement grew in the late 18th century, the Whigs generally moved towards supporting abolition, while Tory governments opposed and delayed it for decades. However, both parties had previously supported and profited from the trade. The Liberal Democrats, as successors to the Whigs, and the Conservatives, as successors to the Tories, inherit this complex legacy. Lib Dem leader Ed Davey has said he supports “full transparency” and it is “vital that we face up to the full truth of Britain’s history”. The Conservative party, under Kemi Badenoch, has emphasized Britain’s role in ending slavery, but the register reveals a more nuanced history.
Key Takeaways
- The slave trade was a state-backed operation supported by both Tories and Whigs.
- Many MPs were investors in the slave trade, and some owned plantations.
- Abolition was opposed by Tory governments for decades, while Whigs gradually supported it.
- Modern political parties must confront this history for full transparency.

| Party | Stance on Slave Trade | Notable Investors |

Modern Implications and the Call for Reparations
The register’s publication comes amid renewed calls for reparations and a UN declaration that the historic enslavement and trafficking of African people was “the gravest crime against humanity”. The data shows that Britain’s wealth was built on this state-backed operation, and addressing this legacy requires acknowledging the full truth. As Ed Davey noted, facing up to this history is vital for justice and reconciliation.
