206 states share the map in 1840. The largest by mapped area are Russia, United Kingdom and Qing.

Russia is the largest state on the map in 1840, a position it has held since 1633 (before that: Spanish Empire). It stays in first place until 1917, when United Kingdom takes over. The five largest states hold 53% of all land with a recorded ruler. 21% of the land on the map has no recorded state. The number of states is about the same as in 1830: 206 against 211.
