Over the past 10 days, two major publications have landed simultaneously and created something historians have long sought: a searchable, evidence-based accounting of Britain's slave trade infrastructure. The Register of British Slave Traders, compiled by historians at britishslavetraders.org, runs to 636 pages and names not just the major trading companies but the ordinary participants — soap boilers, cheesemongers, surgeons, diplomats — who held shares, co-owned voyages, or invested in the Royal African Company, which trafficked more Africans to the Americas than any other English enterprise. Alongside it, the Former British Colonies Enslavement Registers made almost 4 million records of enslaved people across 20 former British colonies searchable by the general public for the first time. The registers are striking not for what they reveal in the abstract — Britain's centrality to the transatlantic slave trade has been established scholarship for decades — but for what they make accessible. The names of the enslaved, recorded as units in ledgers of trade and profit. The names of investors, recorded as participants in a functioning financial system. This was not a peripheral industry. It was integrated into the City of London's insurance markets, Liverpool's shipping lanes, Manchester's cotton supply chains, and the Church of England's colonial theology. As the Guardian's Chris Osuh puts it: "Where was Manchester getting its cotton from? Where were the ships from Liverpool going? The insurance industry and stockbrokers in London — what were they selling shares in?" The political difficulty is not that the evidence is contested. It's that engaging with it threatens two things simultaneously: national identity and money. Caribbean nations are mounting reparations claims with increasing legal sophistication, and these records move the conversation from moral abstraction toward something closer to discoverable liability. The backlash, Osuh argues, "is being kept alive because it goes to the heart of two things so dear to western societies: their identity as heroic, and their money." Britain's relationship with this history follows a specific pattern: enormous cultural appetite for the past — period dramas, Tudor kings, two world wars — combined with a near-total absence of enslavement from mainstream historical narrative. The offshoring is geographic and psychological. Slavery happened in the colonies, so it could be treated as someone else's story. But the registers show the opposite: the financial infrastructure was domestic. The investors were in London. The supply chains ran through English ports. The profits built English institutions. What's changed is the scholarly landscape. Research is now multi-continental and multi-racial, involving Black scholars alongside white European and American historians. This makes it harder for critics to frame the work as identity-driven advocacy. "Beyond the desire for justice, there is a desire for knowledge," Osuh says. The evidence base is growing in volume and specificity, and the old minimisation strategies — "we don't have to apologise, we don't owe you anything" — increasingly require ignoring your own archives. The core tension is between two uses of history. One leverages the past for national myth-making — the heroic island nation that punches above its weight. The other treats history as an accounting exercise: who did what, where, and what were the material consequences. The registers are a product of the second tradition, and they are difficult to argue with because they are not interpretive. They are receipts. The 20-year question is whether this evidence accumulation reaches a tipping point that forces institutional response — educational reform, reparations negotiations, revised public narratives — or whether the myth-making apparatus proves durable enough to absorb even this. The scholar Eric Williams observed that "British historians wrote almost as if Britain had introduced Negro slavery solely for the satisfaction of abolishing it." The registers make that framing harder to sustain, but not impossible. Myths are not defeated by evidence alone.
