Question

How was the Roman Republic set up?

Answer 1

Answer:

It all began when the Romans overthrew their Etruscan conquerors in 509 B.C.E. Centered north of Rome, the Etruscans had ruled over the Romans for hundreds of years. Once free, the Romans established a republic, a government in which citizens elected representatives to rule on their behalf.

Then the Great Roman Empire started its supports in its historic construction.
