By about 800bc the Po Valley was inhabited by a number of tribes belonging to the Celtic peoples. These tribes belonged to a culture that extended west to Spain, north to Britain and east to the Danube River.
At this time the lands south of the Po Valley were inhabited by a number of different tribes and peoples. All these people spoke varieties of language called Italic. These peoples included the Samnites, Etruscans and Latins.
