Occupation of the region

A battle may result in the occupation of the region. The occupied region does not join the invading country until the end of the war, but begins to generate treasury revenue, although in a reduced amount. The occupied region supplies natural resources to the invading country, but receives nothing in return. At the same time, each occupied region forces the invader to leave a part of the army as a garrison in the region. The population of an occupied region can provoke an uprising against the invaders and sometimes even win it. A significant outnumbering of occupied regions usually leads to the victory of one of the participants in the war. If the war ends as a result of peace talks, the occupied regions will remain under the control of the invading countries.

Gameplay Tips
A region, which was temporarily occupied during war, starts to work for the occupier, although with a significant efficiency loss. Even the temporary loss of a key region can destroy the economy of an entire country.
