A map of Italy in 4th century BC, showing various tribe confederations/alliances/groups in the wake of the Latin War. Borders are of course only approximate. For clarity the northern border of modern Italy is marked, in reality the Celtic tribes extended way beyond that line. 
Labels in Latin.

File modelled after File:Italy 400bC en.svg. Includes elements of File:Italy provincial location map.svg and the map template.
