The various empires after the middle ages increase their power and influence by controlling large quantities of territories.
Explanation:
An empire comprised of a centralized state which controls large quantities of territory and many diverse populations.
Empires are increasing and growing because power and influence are expanding and then they can collapse if they lose sight from too much territory or whether they are killed.
The kingdom of Gupta had ceased to exist in 550 CE. But for another century a small Gupta Empire existed. Gupta is a paradigm of a colonial decline in which the central state still remains, but is incapable of expanding its power and influence beyond a small area.
By comparison to that of the Western Roman Empire, whose last emperor was forced out of power, the hierarchical Roman regime was abolished.
