Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the Italian city of Rome in the 8th cent
ury BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC), and Roman Empire (27 BC–476 AD) until the fall of the western empire.
Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually controlled the Italian Peninsula, assimilated the Greek culture of southern Italy (Magna Grecia) and the Etruscan culture, becoming a dominant power in the Mediterranean region and parts of Europe. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly 20% of the world's population at the time. It covered around 4 million square kilometres (1.5 million square miles) at its height in AD 117.
The Roman state evolved from an elective monarchy to a democratic classical republic and then to an increasingly autocratic semi-elective military dictatorship during the Empire. Through conquest, cultural, and linguistic assimilation, at its height it controlled the North African coast, Egypt, Southern Europe, and most of Western Europe, the Balkans, Crimea, and much of the Middle East, including Anatolia, Levant, and parts of Mesopotamia and Arabia. It is often grouped into classical antiquity together with ancient Greece, and their similar cultures and societies are known as the Greco-Roman world.
