Liguria
In the north-western mountain-land of Italy, whose valleys and hills were occupied chiefly by the much-subdivided Ligurian stock, the Romans pursued a similar course. Those dwelling immediately to the north of the Arno were extirpated. This fate befell chiefly the Apuani, who dwelt on the Apennines between the Arno and the Magra, and incessantly plundered on the one side the territory of Pisae, on the other that of Bononia and Mutina. Those who did not fall victims in that quarter to the sword of the Romans were transported into Lower Italy to the region of Beneventum (574); and by energetic measures the Ligurian nation, from which the Romans were obliged in 578 to recover the colony of Mutina which it had conquered, was completely crushed in the mountains which separate the valley of the Po from that of the Arno. The fortress of Luna (not far from Spezzia), established in 577 in the former territory of the Apuani, protected the frontier against the Ligurians just as Aquileia did against the Transalpines, and gave the Romans at the same time an excellent port which henceforth became the usual station for the passage to Massilia and to Spain. The construction of the coast or Aurelian road from Rome to Luna, and of the cross road carried from Luca by way of Florence to Arretium between the Aurelian and Cassian ways, probably belongs to the same period.
With the more western Ligurian tribes, who held the Genoese Apennines and the Maritime Alps, there were incessant conflicts. They were troublesome neighbours, accustomed to pillage by land and by sea: the Pisans and Massiliots suffered no little injury from their incursions and their piracies. But no permanent results were gained amidst these constant hostilities, or perhaps even aimed at; except apparently that, with a view to have a communication by land with Transalpine Gaul and Spain in addition to the regular route by sea, the Romans endeavoured to clear the great coast road from Luna by way of Massilia to Emporiae, at least as far as the Alps—beyond the Alps it devolved on the Massiliots to keep the coast navigation open for Roman vessels and the road along the shore open for travellers by land. The interior with its impassable valleys and its rocky fastnesses, and with its poor but dexterous and crafty inhabitants, served the Romans mainly as a school of war for the training and hardening of soldiers and officers.
Corsica
Sardinia
Wars as they are called, of a similar character with those against the Ligurians, were waged with the Corsicans and to a still greater extent with the inhabitants of the interior of Sardinia, who retaliated for the predatory expeditions directed against them by sudden attacks on the districts along the coast. The expedition of Tiberius Gracchus against the Sardinians in 577 was specially held in remembrance, not so much because it gave “peace” to the province, as because he asserted that he had slain or captured as many as 80,000 of the islanders, and dragged slaves thence in such multitudes to Rome that “cheap as a Sardinian” became a proverb.
