Even so, it took time for the other states of Italy to wake up to the nature of the predator in their midst. For the first century of the Republic’s existence the Romans found it a struggle to establish their supremacy over cities barely ten miles from their own gates. Yet even the deadliest carnivore must have its infancy, and the Romans, as they raided cattle and skirmished with petty hill tribes, were developing the instincts required to dominate and kill. By the 360s BC they had established their city as the mistress of central Italy. In the following decades they marched north and south, crushing opposition wherever they met it. By the 260s, with startling speed, they had mastered the entire peninsula. Honour, of course, had demanded nothing less. To states that humbly acknowledged their superiority, the Romans would grant such favours as a patron condescends to grant his clients, but to those who defied them, only ceaseless combat. No Roman could tolerate the prospect of his city losing face. Rather than endure it, he would put up with any amount of suffering, go to any lengths.
The time soon came when the Republic had to demonstrate this in a literal struggle to the death. The wars with Carthage were the most terrible it ever fought. A city of Semitic settlers on the North African coast, dominating the trade routes of the western Mediterranean, Carthage possessed resources at least as great as Rome’s. Although predominantly a maritime power, she had indulged herself for centuries with bouts of warfare against the Greek cities of Sicily. Now, poised beyond the Straits of Messina, the Romans represented an ominous but intriguing new factor in Sicily’s military equation. Predictably, the Greeks on the island could not resist embroiling the Republic in their perennial squabbles with Carthage. Equally predictably, once invited in, the Republic refused to play by the rules. In 264 Rome transformed what had been a minor dispute over treaty rights into a total war. Despite a lack of any naval tradition, and the loss of fleet after fleet to enemy action or storms, the Romans endured over two decades of appalling casualties to bring Carthage, at last, to defeat. By the terms of the peace treaty forced on them, the Carthaginians undertook a complete withdrawal from Sicily. Without ever having intended it, Rome found herself with the nucleus of an overseas empire. In 227 Sicily was constituted as the first Roman province.
The theatre of the Republic’s campaigning was soon to grow even wider. Carthage had been defeated, but not smashed. With Sicily lost, she next turned her imperial attentions to Spain. Braving the murderous tribes who swarmed everywhere in the mountains, the Carthaginians began to prospect for precious metals. The flood of wealth from their mines soon enabled them to contemplate resuming hostilities. Carthage’s best generals were no longer under any illusions as to the nature of the enemy they faced in the Republic. Total war would have to be met in kind, and victory would be impossible unless Roman power were utterly destroyed.
It was to achieve this that Hannibal, in 218, led a Carthaginian army from Spain, through southern Gaul and over the Alps. Displaying a mastery of strategy and tactics far beyond that of his opponents, he brought three Roman armies to sensational defeat. In the third of his victories, at Cannae, Hannibal wiped out eight legions, the worst military disaster in the Republic’s history. By every convention and expectation of contemporary warfare, Rome should have followed it by acknowledging Hannibal’s triumph, and attempting to sue for peace. But in the face of catastrophe, she showed only continued defiance. Naturally, at such a moment, the Romans turned for guidance to the prophecies of the Sibyl. These prescribed that two Gauls and two Greeks be buried alive in the city’s marketplace. The magistrates duly followed the Sibyl’s advice. With this shocking act of barbarism, the Roman people demonstrated that there was nothing they would not countenance to preserve their city’s freedom. The only alternative to liberty – as it had always been – was death.
And grimly, year by year, the Republic hauled itself back from the brink. More armies were raised; Sicily was held; the legions conquered Carthage’s empire in Spain. A decade and a half after Cannae Hannibal faced another Roman army, but this time on African soil. He was defeated. Carthage no longer had the manpower to continue the struggle, and when her conqueror’s terms were delivered, Hannibal advised his compatriots to accept them. Unlike the Republic after Cannae, he preferred not to risk his city’s obliteration. Despite this, the Romans never forgot that in Hannibal, in the scale of his exertions, in the scope of his ambition, they had met the enemy who was most like themselves. Centuries later statues of him were still to be found standing in Rome. And even after they had reduced Carthage to an impotent rump, confiscating her provinces, her fleet, her celebrated war-elephants, the Romans continued to dread a Carthaginian recovery. Such hatred was the greatest compliment they could pay a foreign state. Carthage could not be trusted in her submission. The Romans looked into their own souls and attributed the implacability they found there to their greatest foe.
Never again would they tolerate the existence of a power capable of threatening their own survival. Rather than risk that, they felt themselves perfectly justified in launching a pre-emptive strike against any opponent who appeared to be growing too uppity. Such opponents were easy – all too easy – to find. Already, even before the war with Hannibal, the Republic had fallen into the habit of dispatching the occasional expedition to the Balkans, where its magistrates could indulge themselves by bullying princelings and redrawing boundaries. As the Italians would have confirmed, the Romans had an inveterate fondness for this kind of weight-throwing, reflecting as it did the familiar determination of the Republic never to brook disrespect. For the treacherous and compulsively quarrelsome states of Greece, however, it was a lesson which took some grasping. Their confusion was understandable – in the early years of their encounters with Rome, the Republic did not behave at all in the manner of a conventional imperial power. Like lightning from a clear sky, the legions would strike with devastating impact, and then, just as abruptly, be gone. For all the fury of these irregular interventions, they would be punctuated by lengthy periods when Rome appeared to have lost interest in Greek affairs altogether. Even when she did intervene, her incursions across the Adriatic continued to be represented as peace-keeping ventures. These still had as their object not the annexation of territory but the clear establishment of the Republic’s prestige, and the slapping down of any overweening local power.
In the early years of Roman engagement in the Balkans, this had effectively meant Macedon. A kingdom to the north of Greece, Macedon had dominated the peninsula for two hundred years. As heir to the throne of Alexander the Great, the country’s king had always taken it for granted that he could be quite as overweening as he pleased. Despite repeated punishing encounters with the armies of the Republic, such an assumption never entirely died, and in 168 BC Roman patience finally snapped. Abolishing the monarchy altogether, Rome first of all carved Macedon into four puppet republics, and then in 148, completing the transformation from peace-keeper to occupying power, established direct rule. As in Italy, where roads criss-crossed the landscape like the filaments of a net, engineering prowess set the final seal on what military conquest had begun. The via Egnatia, a mighty gash of stone and gravel, was driven through the wilds of the Balkans. Running from the Adriatic to the Aegean Sea, this highway became the vital link in the coffle joining Greece to Rome. It also provided ready access to horizons even more exotic, those beyond the blue of the Aegean Sea, where cities glittering with gold and marble, rich with works of art and decadent cooking practices, seemed positively to invite the Republic’s stern attentions. Already, in 190, a Roman army had swept into Asia, pulverised the war-machine of the local despot and humiliated him before the gaze of the entire Near East. Both Syria and Egypt, the two local superpowers, hurriedly swallowed their pride, learned to tolerate the meddling of Roman ambassadors, and grovellingly acknowledged the Republic’s hegemony. Rome’s formal empire was still limited, being largely confined to Macedon, Sicily and parts of Spain, but her reach by the 140s BC extended to strange lands of which few back in Rome had even heard. The scale and speed of her rise to power was something so startling that no one, least of all the Romans themselves, could quite believe that it had happened.
