How did Rome display their power

They displayed their power by territory size and their feirce armies.

Explanation:

Rome was able to gain its empire in large part by extending some form of citizenship to many of the people it conquered. Military expansion drove economic development, bringing enslaved people and loot back to Rome, which in turn transformed the city of Rome and Roman culture.

The Roman Republic became the Roman Empire in 27 BCE when Julius Caesar's adopted son, best known as Augustus, became the ruler of Rome. Augustus established an autocratic form of government, where he was the sole ruler and made all important decisions.
