192 states share the map in 400 BC. The largest by mapped area are Achaemenid Empire, Chu State and Babyllinioi.

Achaemenid Empire is the largest state on the map in 400 BC, as it has been since the atlas begins in 467 BC. It stays in first place until 331 BC, when Macedonia takes over. The five largest states hold 47% of all land with a recorded ruler. 85% of the land on the map has no recorded state. The number of states is about the same as in 450 BC: 192 against 190.
