The European country of Italy has been inhabited by humans since at least 850,000 years ago. Since classical antiquity, ancient Etruscans, various Italic peoples (such as the Latins, Samnites, and Umbri), Celts, Magna Graecia colonists, and other ancient peoples have inhabited the Italian Peninsula. In antiquity, Italy was the homeland of the Romans and the metropole of the Roman Empire's provinces. Rome was founded as a kingdom in 753 BC and became a republic in 509 BC, when the Roman monarchy was overthrown in favour of a government of the Senate and the People. The Roman Republic then unified Italy at the expense of the Etruscans, Celts, and Greek colonists of the peninsula. Rome led Socii, a confederation of the Italic peoples, and later with the rise of Rome dominated Western Europe, Northern Africa, and the Near East.
