This article introduces GeoEPR, a geocoded version of the Ethnic Power Relations (EPR) dataset that charts politically relevant ethnic groups across space and time. We describe the dataset in detail, discuss its advantages and limitations, and use it in a replication of Cederman, Wimmer and Min’s (2010) study on the causes of ethnonationalist conflict. We show that territorial conflicts are more likely to involve groups that settle far away from the capital city and close to the border, while these spatial variables have no effect for governmental conflicts.
