This interactive video 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 represent individual slave ships. The larger the dot, the more enslaved people on board. Click on a dot to learn about the ship’s flag, 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 in an astounding two minutes. Often visuals can get an idea across faster than words.
