World map displaying Seshat's division of regions inspired by the UN geographic regions (IMAGE)
Caption
On the map, each marker represents a "Natural Geographic Area" (NGA), as defined by Seshat experts. The researchers identified and collected data about each polity that occupied or overlapped with each NGA over the course of history. The colors correspond to the regional division scheme used in the current paper based on the UN geographic regions.
