The Lusitanian War, called in Greek Pyrinos Polemos ("the Fiery War"), was a war of resistance fought by the Lusitanian tribes of Hispania Ulterior against the advancing legions of the Roman Republic from 155 to 139 BC. The Lusitanians revolted on two separate occasions (155 and again 146) and were pacified. In 154 BC, a long war in Hispania Citerior, known as the Numantine War, was begun by the Celtiberians. It lasted until 133.
Under the leadership of Viriathus, the Lusitanian tribes moved from guerilla warfare to take on 2 Roman legions (some 10,000 troops), by leading them onto a narrow passage through the mountains overhanging a fatal ledge.
They killed over 4,000 Romans, wounding many others.
Outside of Hat's Carthaginian Allies which has two Lusitanians, there is no one else selling Lusitanians.
