The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. Īncient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula.

In modern historiography, ancient Rome encompasses the founding of the Italian city of Rome in the 8th century BC, the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC), Roman Empire (27 BC– 395 AD), and the collapse of the Western Roman Empire in the 5th century AD.

Another suggested end date is the reorganization of the Italian peninsula and abolition of separate Western Roman administrative institutions under Emperor Justinian during the latter half of the 6th century.
