University of Colorado Boulder: Interactive map gets closer to pinpointing African origins erased during slave trade. “Conflicts among African nations during the collapse of the kingdom of Oyo in the early 19th century resulted in the enslavement of hundreds of thousands of people. Soldiers and traders removed men, women and children from their homes, transported them to coastal ports and loaded them onto slave ships—their names, birth places and family ties erased. Historians have a pretty good record of where these individuals departed Africa, but due to a lack of primary sources, little is known about where they originated before boarding slave ships. CU Boulder researchers are hoping to change that with a first-of-its-kind mathematical model estimating conditional probabilities of African origins during the transatlantic slave trade.” I have this under “Research” instead of “New Resources” because the map is more an expression of the model and not a polished mechanism for attaining information.
