What happened
By the early eighteenth century the transatlantic slave trade operated on a three-legged route that historians call the triangular trade. Ships left European ports, chiefly Liverpool, Bristol, and Nantes, loaded with manufactured goods: iron bars, textiles, firearms, and liquor. On the West African coast, traders exchanged these goods for captive Africans purchased from African merchants and rulers. The ships then crossed the Atlantic on the Middle Passage and sold survivors in the Americas, before loading sugar, tobacco, cotton, and other colonial products for the return voyage to Europe, completing the cycle. Liverpool overtook Bristol as Britain's leading slaving port by 1750 and by the period 1793 to 1807 accounted for roughly 85 percent of all British slaving voyages. The profits reshaped these cities: warehouses, docks, insurance markets, and elegant townhouses in Liverpool, Bristol, Nantes, and Bordeaux were built substantially on capital earned from the trade.
Why it matters
The triangular trade made slaving profitable at every stage of the voyage rather than only on the sale of captives, which is what allowed it to scale into an industrial-sized traffic rather than remaining a series of isolated raids. The wealth it generated financed banks, insurance markets, and industries in Liverpool, Bristol, and Nantes that outlasted the trade itself by generations.
How we know
Colonial Williamsburg's Slavery and Remembrance project documents the triangular route and the rise of these specific ports using shipping records and port customs data; the Trans-Atlantic Slave Trade Database's own voyage records independently confirm Liverpool's dominance in the trade's final decades.
