Before the Roman times, the area of today's Tuscany was called Eturia, because of the Etruscan culture. It was also known by the Greeks as "Tyrhennia" because of the Tyrhennian Sea. The people of Etruria were named Etruscans, and their complex culture was centered on numerous city-states, such as Veii. In their golden age, they were able to dominate Latio, Mantua, and the north-eastern coast of the Italian Peninsula. Corsica was also conquered. The Etruscans were a heavily civilized people, very influenced by their neighbors on Campania and the Balkans, the Greeks. They were responsible of importing much of the Greek culture into Rome. The Etruscans were the most powerful nation on Italy until the rise of Rome.
