During the early periods between 616 and 509 B.C.E., the Etruscan kings ruled the Roman Republic.
In 509 B.C.E., the oligarchs overthrew the last Etruscan king.
After the oligarchs overthrew the last Etruscan king, the Romans fell into two social classes. The higher class, the Patricians and the lower class, the Plebeians.
The Patricians were sitting pretty with their enormous fortune. Meanwhile, the Plebeians got fed up with the very small fortune that they received.
In refute, the Plebeians went on strike and left the roman premises. The Pats were left defenseless because the only soldiers were Plebeians. The Plebeians wrote a list of conditions under which the Plebeians would reenter the empire.
In the end, the rights for Plebeians were granted and the Plebeians got to have a representative in the court so that they could have a say in the laws made.
