Rome (English pronunciation: /ˈroʊm/; Italian: Roma pronounced [ˈroːma] ( listen); Latin: Rōma) is the capital of Italy and the country's largest and most populated city and comune, with over 2.7 million residents in 1,285.3 km2 (496.3 sq mi). The city is located in the central-western portion of the Italian Peninsula, on the Tiber River within the Lazio region of Italy.
Rome's history spans two and a half thousand years. It was the capital city of the Roman Kingdom, the Roman Republic and the Roman Empire, which was the dominant power in Western Europe and the lands bordering the Mediterranean Sea for over seven hundred years from the 1st century BC until the 7th century AD. Since the 1st century AD Rome has been the seat of the Papacy and, after the end of Byzantine domination, in the 8th century it became the capital of the Papal States, which lasted until 1870. In 1871 Rome became the capital of the Kingdom of Italy, and in 1946 that of the Italian Republic..
