The Roman Republic was established in 509 BCE after the overthrow of the Etruscan monarchy, organizing the government into a combination of aristocracy, oligarchy, and democracy with citizens electing consuls and a senate to advise them. Society was divided between the wealthy patrician class and the plebeian majority, who engaged in occasional strikes to gain more political power. The republican government structure consisted of two annually elected consuls, the senate which controlled finances and foreign policy, and plebeian tribunes who could veto consular decisions and advocate for the common people.
