North of the Latins in Rome, there was another group. Italian archeologist Paracle Ducate named them after ruins discovered near the town of Villanova. Arriving in North Central Italy before 1000 BCE, they exploited the metal-rich areas of the region, and they developed key towns such as Cerveteri and Tarquinia. Trading and mingling with Greeks, Phoenicians of ancient Carthage in North Africa, and even the Latins, they developed into the people north of Rome whom we call the Etruscans. [SOUND] The Etruscans took over Rome in the later 7th century BCE, and decided to create a Forum in the swampy area there. >> When they decide that they want to do something else with the Forum, their first order of business is to do something with the water. There is this flooding that comes into the valley at irregular times, it can't be predicted, the Tiber is a very unruly river. It was a river that really created enormous problems for the city of Rome throughout its history. So the problem is that the valley is big, and so you need a lot of dirt or other material to fill it up. The other big piece of architectural work is the drainage under the floor. The so called cloaca maxima, the great drain, that had to be built at the same time as when the forum was built. And the only problem is archaeologically it has been patched up and built and rebuilt so many times and still working today as a major storm drain in that area of the city. >> But where did these Etruscan invaders come from?
