Which term describes a society that conquers regions outside its homeland and subjects different groups of people to its rule? a: city-state b: empire c: theocracy d: state

   B. Empire

Explanation:  The empire is a typical arrangement for some past times, when it was common to conquer the territories of other ethnic groups with different cultural characteristics and language, and subdue their power and rule.

The city-state was also more present in the past, and is usually associated with a cosmopolitan city that has all the features of an independent state. They were characteristic in specific geographic areas, where such a city-state was inevitable, but also in the context of political and economic conditions such as Venice in the past and the like.

State is the country in which the majority of a particular entity lives, but there are also minorities, and according to the world legal regulations, these minorities would be entitled to all rights under international conventions. And that is the difference between the state and the empire, because subordinates in the empire did not have to have all rights, sometimes even no rights.

Theocracy is a system of regulation where it is governed by a religious law, whether it is a monarchy, a republic, an empire or a city, that is, a religion-based law, whether there are several entities within or not,  whether one of the entities is subjugated or not.
