Describe how Rome gained its power.

Military conquests and slave labour.

Explanation:

It was a long way to Rome's rise to world power; it is not a process that happened "overnight". Rome has been continuously expanding since its founding. The biggest obstacle in the spread of Rome was Carthage, which was one of the ancient world's greatest naval powers. Rome launched several wars against Carthage known in history as the Punic Wars.

After conquering Carthage, Rome spread unstoppably. In this context, primarily thanks to the military. The Roman army was led by great discipline. Thanks to new military techniques and capable leadership, Rome was continuously expanding. Slaves encouraged the spread of rhyme.

A large number of conquered states paid taxes, so the state coffers were regularly full.
