Three Phases of Rome

753–509 BC
Roman Kingdom (244 years)
Seven legendary kings ruled Rome. The city grew from a small settlement on the Tiber to a regional power. The last king, Tarquin the Proud, was expelled in 509 BC, ending the monarchy.
509–27 BC
Roman Republic (482 years)
Elected magistrates (consuls, praetors) governed Rome, with the Senate as the supreme advisory body. Rome conquered Italy, then the Mediterranean. Julius Caesar's civil war ended the Republic.
27 BC–476 AD
Roman Empire (503 years)
Emperors replaced Republican institutions in practice, though the Republic's forms were maintained. At its height under Trajan, ~70 million people lived under Roman rule. Decline accelerated after 235 AD (Crisis of the Third Century).
