This website and dataset compiles detailed records of over 18,000 indentured servants called serviçais who worked in Angola or were shipped from Angola and sent to coffee and cocoa plantations on the archipelago of São Tomé and Príncipe, both Portuguese colonies, from 1876 to 1896. These serviçais were enslaved in the interior of Angola before being coerced into labour contracts, and most never returned home. Through this website, scholars, students, and the public can learn more about this indentured labour system, and some of the people that shaped the Atlantic world.
