About these borders
The borders come from Cliopatria (v0.2.1, Seshat Global History Databank, CC BY 4.0), the dataset behind our interactive map, with our audited name and border corrections. It records each state's territory year by year from 3400 BC to 2024. Borders before modern surveys are reconstructions: the data draws a state where it held control, and frontier zones, nomadic realms and loose overlordships are approximate. Areas are measured on an equal-area projection. Read how we make our maps.
