What eventually became the Roman Empire began as settlements around the Palatine Hill along the river Tiber in Central Italy. The river was navigable up to that place. The site also had a ford where the Tiber could be crossed. The Palatine Hill and hills surrounding it presented easily defensible positions in the wide fertile plain surrounding them. All these features contributed to the success of the city.

The traditional account of Roman history, which has come down to us through Livy, Plutarch, Dionysius of Halicarnassus and others, is that in Rome’s first centuries, it was ruled by a succession of seven kings. Archaeological evidence does, however, support that a settlement was founded in Rome around the middle of the 8th century BC.

According to legend, the foundation of Rome took place 438 years after the capture of Troy (1182 BC), according to Velleius Paterculus (VIII, 5). It took place shortly before an eclipse of the sun; some have identified this eclipse as one observed at Rome on June 25, 745 BC.

The traditional date for the founding of Rome, based on a mythological account, is April 21, 753 BC, and the city and surrounding region of Latium has continued to be inhabited with little interruption since around that time.

Rome grew from pastoral settlements on the Palatine Hill and surrounding hills approximately 18 miles (29 km) from the Tyrrhenian Sea on the south side of the Tiber. Another of these hills, the Quirinal Hill, was probably an outpost for another Italic-speaking people, the Sabines. At this location the Tiber forms a Z-shape curve that contains an island where the river can be forded. Because of the river and the ford, Rome was at a crossroads of traffic following the river valley and of traders travelling north and south on the west side of the peninsula.

Archaeological finds have confirmed that in the 8th century BC in the area of the future Rome there were two fortified settlements, the Rumi one on the Palatine Hill and the Titientes one on the Quirinal Hill, backed by the Luceres living in the nearby woods. These were simply three of numerous Italic-speaking communities that existed in Latium, a plain on the Italian peninsula, by the 1st millennium BC. The origins of the Italic peoples is not known, but their Indo-European languages migrated from the east in the second-half of the 2nd millennium BC.
