Replication Data for: A Modelling Strategy to Estimate Conditional Probabilities of African Origins: The Collapse of the Oyo Empire and The Transatlantic Slave Trade, 1817–1836

Henry Lovejoy compiled a list of cities in the kingdom of Oyo involved in conflict from 1817–1836, their corresponding spatial coordinates, start and end dates surrounding conflict at each city, political affiliations of the city, and an extensive list of primary or secondary sources from which the data are derived. A conflict intensity scale is encoded as a categorical variable with two levels: 2 indicates a city was attacked and 3 represents a city that was destroyed. Cities could be attacked or destroyed over several years. Cities were often rebuilt in the same or slightly different locations and attacked or destroyed again in subsequent years. New cities were also founded, which is represented with 9 in the data set. For an annual overview of political and conflict maps, slave ship departures, available documentation, and imagery (including photographs) of the people involved in Oyo's collapse see http://www.yorubadiaspora.org. GIS materials compiled by Lovejoy are published at https://doi.org/10.1163/2405836X-00402002.
