Step-by-step explanation:
The most common way that Classical Civilizations like Rome gained, consolidated, and maintained their power was through a combination of military dominance, political alliances, infrastructure development, and cultural assimilation.
The Romans had successful military strategies such as dividing and conquering their enemies, negotiating from a position of strength, and establishing colonies in conquered lands for defense. They also built well-constructed roads to connect Rome with its colonies and quickly respond to rebellions.
Additionally, Rome assimilated conquered peoples by offering them citizenship, allowing self-government if they honored Rome's alliances, and providing infrastructure like aqueducts, public baths, and roads. Through these methods, Rome expanded its military might and cultural influence throughout its empire.
