Other forms: empires
An empire is a group of countries ruled by one power. The Roman Empire, build an empire, the empire fell.
The defining feature is rule over other peoples rather than size, which is why a large country is not an empire and a small one with colonies is. Figuratively a business empire is a set of holdings under one owner. Note that the Latin imperium means command, from imperare, to order.
