What is the most important factor when building an empire?

In this essay I will write about what is the most important factor when building an empire.

Also part of the social factor is that all the countries in the empire will be allies and because within the empire all the countries are allies The empire will have a huge army which is good in one way because if any country goes to war with them they will have a very a chance of defeating them but it’s bad in another way because that means Rome will have to spend more in the army for an example they would have get every single person in the army going to war mainly metallic shields ,swords and armour which would have used up a large portion of their money.
