A Number Four Centuries in the Making
The Slave Voyages database — built by scholars originally at Emory University and now maintained as an open-access digital archive — documents roughly 36,000 individual slave-trading voyages between 1500 and 1900. Cross-referencing ship manifests, customs records, insurance filings, and court documents from every major trading nation, researchers have arrived at a consensus estimate: approximately 12.5 million captive Africans were embarked for the Americas. An estimated 1.8 million did not survive the crossing. The number is not an approximation offered for dramatic effect — it is the product of decades of archival reconstruction, and it is the baseline every serious historian of the trade now works from.
The Arithmetic of an Atrocity
Of the roughly 12.5 million people embarked, an estimated 10.7 million survived to be disembarked in the Americas. Brazil received the largest share, approximately 4.9 million; the British Caribbean approximately 2.3 million; the Spanish Americas approximately 1.3 million; and British North America and the later United States approximately 400,000 — a comparatively small figure that reflects not restraint but the forced domestic reproduction of an enslaved population once already in place. The trade’s peak came in the eighteenth century, when roughly 6 million people were transported, nearly half the total across four centuries. It did not stop at abolition. Britain outlawed the trade in 1807 and the United States in 1808, but Portuguese, Brazilian, Spanish, and American vessels continued running captives illegally for decades afterward. The last documented slave ship to reach the United States, the Clotilda, landed 110 enslaved Africans in Alabama in 1860 — fifty-two years after the trade had been made illegal.
What the Number Was Built to Conceal
The records the trade generated were built to track cargo, not people. Ship manifests recorded age, sex, and market price. Plantation inventories listed first names alongside livestock. That bureaucratic apparatus required that the people moving through it be counted and not known. But the erasure was never complete. Slave Voyages researchers have recovered the recorded African names of approximately 91,000 individuals from ship logs and colonial records — names that trace specific ethnic origins, day-of-birth naming traditions, and family lines the trade tried to sever. Every one of the 12.5 million had a name before the trade took it. This entry’s contribution-track companion follows one of those names all the way to Fayetteville, North Carolina.
“The number was designed to make them invisible. The archive was designed to bring them back.”
