The Atlantic Slave Trade in Two Minutes

By Andrew Jahn and Jamelle Bouie, 28 July 2020



One of the shocking, largely unknown, horrors of our past, was the systematic evil of slavery. Unfortunately, some people who call themselves Catholic refuse to face the consequences of past European profiteering which organised the effective genocide and the forced abduction of millions Africans over centuries. That tragedy and its effects still play out today. This article includes a graphic animation that gives you some idea of the abhorrent evil of this ‘trade’ in human souls loved by Christ.

Usually, when we say “American slavery” or the “American slave trade,” we mean the American colonies or, later, the United States. But as we discussed in Episode 2 of Slate’s History of American Slavery Academy, relative to the entire slave trade, North America was a bit player. From the trade’s beginning in the 16th century to its conclusion in the 19th, slave merchants brought the vast majority of enslaved Africans to two places: the Caribbean and Brazil. Of the more than 10 million enslaved Africans to eventually reach the Western Hemisphere, just 388,747—less than 4 percent of the total—came to North America. This was dwarfed by the 1.3 million brought to Spanish Central America, the 4 million brought to British, French, Dutch, and Danish holdings in the Caribbean, and the 4.8 million brought to Brazil.

This interactive, designed and built by Slate’s Andrew Kahn, gives you a sense of the scale of the trans-Atlantic slave trade across time, as well as the flow of transport and eventual destinations. The dots—which represent individual slave ships—also correspond to the size of each voyage. The larger the dot, the more enslaved people on board. And if you pause the map and click on a dot, you’ll learn about the ship’s flag—was it British? Portuguese? French?—its origin point, its destination, and its history in the slave trade. The interactive animates more than 20,000 voyages cataloged in the Trans-Atlantic Slave Trade Database. (We excluded voyages for which there is incomplete or vague information in the database.) The graph at the bottom accumulates statistics based on the raw data used in the interactive and, again, only represents a portion of the actual slave trade—about one-half of the number of enslaved Africans who actually were transported away from the continent.
