For example, population pressure describes the consequences of overpopulation . In the case of decreasing territory for individuals due to strong population growth or loss of area and displacement of the population and / or sinking resources , a population, i.e. a society or group that divides an area, may urge to expand the area.

Other reasons can be environmental changes or attacks by enemies. This process is usually linked to warlike consequences (e.g. striving for conquest).

A consequence of acute population pressure in history can be empires that reach a large extent in a relatively short time but go under again relatively quickly ( e.g. Huns , Inca ).
