As part of a Rapid Evidence Assessment Project I am conducting (waiting professional editing to be sent out for review) I collected in one point information on all the conflict-political science Data-sets containing data that extends before 1815. A pared down version of this collection can be found in the a table below. The REA was produced by looking at articles from three quantitative friendly international relations conflict journals between 1970 and 2014. This might be a useful resource for scholars wondering what data is out there that looks to the past. For more information you will have to wait for the published article.
