What you see

  • Each voyage is a dot at its main port of purchase, sized by the people embarked as the databases record or estimate them; where they record the ports, a line carries its route to where the people were landed.
  • Where a view holds more than 2,000 voyages they gather into counted bubbles; zoom in to see each one.
  • Click a voyage for the ship, its flag and captain, its route, the people embarked and landed, and how the voyage ended.
  • Opened from this page, the map plays 1700 to 1866.

Where the data comes from

  • SlaveVoyagesThe Trans-Atlantic Slave Trade Database (2019): about 34,000 voyages from Africa to the Americas.
  • SlaveVoyagesThe Intra-American Slave Trade Database (1.0): about 10,600 voyages between ports in the Americas.

Published databases; SlaveVoyages adds voyages as research finds them, and TAKIP takes a new release when it is imported.

Good to know

  • About 7,900 voyages say only “Africa, port unspecified”: they are drawn at the one point the database gives for that, not at a real port.
  • Many more name only a region, such as the Gold Coast or West Central Africa, and are drawn at its point.
  • Numbers embarked are partly the databases’ estimates; their historical data is public domain, the estimates CC BY-NC 3.0.
