In 1958, the Guinness Book of World Records declared it the smallest colony on Earth: a Portuguese fort in French West Africa, garrisoned by one officer and a handful of men, entirely surrounded by foreign territory. Fort Sao Joao Baptista de Ajuda in Ouidah, Benin, had by then become a geopolitical absurdity -- a colonial holdout so small it barely qualified as a dot on the map. But its origins were anything but trivial. Built in 1721 to supply enslaved people to sugar and tobacco plantations in Bahia, Brazil, the fort was the last of three European fortifications erected in Ouidah to tap the human trade of the Slave Coast. Its history spans the full arc of the Atlantic slave trade, from peak brutality to legal abolition to the illicit trade that flourished in defiance of the law.

When Britain, France, and Portugal legally abolished the slave trade in the early 19th century, the Ouidah forts were abandoned or repurposed.

When France colonized Dahomey in the 1890s, Portuguese diplomats insisted on retaining sovereignty over the tiny enclave, now entirely surrounded by French territory. A small detachment of troops from ...
