The Roman Republic
While the Hellenistic monarchs were settling down to their feuding, the Romans were running into problems of their own. In 264 BC, war exploded in Sicily between Rome and the dominant power in the Western Mediterranean, Carthage. A one time Phoenician outpust, the Carthaginians had used the wealth of their trading connections and their comparatively advanced Phoenician civilization to dominate the less advanced peoples of Western Europe. Sicily was an important source of grain for Rome whose continued expansion desperately required wheat imports to feed the swelling populations that could no longer be grown locally. Defeat in the first Punic War (Punic was the Latin word for Phoenician) would have spelled the end for Rome, and with the sophisticated and brilliant Phoenician navy facing the highly disciplined soldiers of Rome at sea where they had no experience, things looked grim.
The first eight fleets sent out by Rome were destroyed, with Roman admirals using unconventional strategies in an attempt to turn sea battles into more familiar "land" engagements. The Roman Senate discussed seriously the possibility of surrender, but a powerful block still opposed peace. The Senate approved a special tax upon themselves (all other sources of taxation having been exhausted) and without the help of their allies (who had fulfilled all their military obligations under treaty) they built a ninth fleet of traditional warships with the hope that they had learned enough through the two decades of fighting to go toe to toe with the Carthaginians. In 241 BC, the Roman navy triumphed and secured Sicily as a Roman province.
By 222 BC, the Romans had unified Italy under their control, and this more than any other reason prompted the Carthaginians to declare war in 218 BC, beginning the most storied conflict in Roman history, the Second Punic War. The Carthaginian general Hannibal proved brilliant. He marched his army complete with war elephants across Africa, through Spain, over the Pyrenees and the Alps and descended upon Italy where he never lost a major engagement. Yet, he was no engineer and had no method for beseiging the walled city successfully. In battle after battle, he conquered Roman armies and burned their crops only to be snubbed by the proud Romans who would not submit to his peace terms. In 206 BC, the Romans were able to stir up enough trouble in North Africa that Hannibal had to return home to secure his rear. A new Roman general, Scipio, led a Roman expeditionary force to Africa and secretly negotiated a treaty with Carthage's African allies. When Hannibal met the Romans on the battlefield of Zama, he called for his allies to charge at the critical moment, and charge they did, crushing the Carthaginian army from the rear. By 201 BC, the Romans successfully forced the city to surrender and this time there was no quarter. After the years of devastation and war crimes, the Romans sacked Carthage and humiliated the city. They would never again rise as a major power; Rome on the other hand was just emerging.
197 BC was the beginning of the end of the Hellenistic Period, when Rome defeated the Antigonid dynasty and "freed" the Greeks. No one was under the illusion that they would exert any less influence over the area than the Macedonians. Thanks to the fractured politics and infighting throughout Greece, the Romans did not need to rule, but only "settle disputes" to achieve effective control of Greece. This lasted until Corinth, outraged over a Roman ruling against it, revolted against Roman authority; the response was swift. In 146 BC, the Romans sacked the city and seized direct control of Greece, dividing the region into Roman provinces.
This didn't mean that Greek influence would ever go away. Its success and its legacy would live on in the civilizations that came after it, Rome not least of all. However, where the Greek were scholars and philosopohers who loved to argue, the Romans loved martial virtues: doing your duty unquestioningly, maintaining peak physical condition (both important skills for all soliders), and accepting the dictates of fate – after all, fate had dictated that Rome rule the known world, and no Roman found any reason to argue with that. The Romans were greatly divided over the importance of Greece. Many Roman families embraced Greek culture until Greek slaves were highly sought after as tutors and artists in Rome. In the end they copied many Greek innovations – drama, law and the Greek court system based on adversarial lawyers, popular education, and poetry. Roman religion became so bound up with Greek mythology that the stories are virtually identical except for the Roman names.
However, the Romans were not creative or inquisitive in the way that the Greeks were. The Roman temperment was the defining factor in this reality. Socrates, Plato, and Aristotle's love of dialogue as a technique for arguing your way to truth never caught on in Rome. Stoicism remained the dominant Roman philosophy, admiring heroic indifference to the world. When the world threw a massive problem in front of the Greeks, they argued over it and picked it apart which gave them techniques to learn about it. When it threw a massive problem in front of the Romans, if it was military they sent the army out to crush it, and if it was not they sat back and shrugged their shoulders at it. It's easy to see why the Romans took readily to Christianity which declared that nothing in this world mattered. While the Romans learned, grew, and borrowed heavily from the Greeks, Stoicism remained closer to the Roman heart throughout the Republic and the Empire than the Greek love of learning. This became more and more pronounced through the years of the Empire.
The Roman view of education was also profoundly different. For the Greeks education was about developing and pursuing a liberal arts education for the betterment of the individual; education was necessary to be a "man" in Greek culture. In Rome, being a man meant physical prowess and success in business, politics, or in battle. Education was important in Rome, but only in so far as it contributed to one's success in these areas. They saw the Greek goal of personal development as effeminate and impractical. So it is ironic that the Romans adopted most of their curriculum from the Greeks, even as they looked down their noses at the goals of a Greek education.
146 BC, was also the year a Roman expedition was sent to Carthage in what the Romans euphemistically called the Third Punic War. A prominent senator had traveled to the city and seen that the Carthaginians had rebuilt a thriving city. By raising horrifying specters of Hannibal, he convinced the Senate to send an army to sack the city and raze it to the ground, reportedly even sowing salt in the earth to prevent crops from growing. Over the next hundred years, Rome expanded from Anatolia to Egypt, turning the Mediterranean into a Roman Sea; while the Romans never unified all of Europe, no other power in history ever controlled the entire coastline of the Mediterranean. No one had been able to stand against the Romans, so it was to be expected that the only threat to Rome could come from inside. The increasingly arrogant Romans finally pushed their allies too far.
Italy revolted in 91 BC because of what they felt was unfair treatment by the Romans. In a flash of that old Roman practicality, the Romans conceded to the grievances of their allies and responded by granting full Roman citizenship to everyone living in Italy. The end of the "Social War" in 88 BC unified Italy; if Rome had continued this policy throughout its provinces, it would have been stronger. However, Roman citizenship included freedom from taxation. The services which the Romans enjoyed were paid for by the citizens of the provinces, so there was never a serious chance that the Romans could expand central government beyond the Italian peninsula. There was nowhere else to obtain funds without taxing themselves, and this was never seriously considered. Politically, the Social War would be the high point of Roman civilization because corruption and ambition were tearing Rome apart from the inside.
With ever more power at stake, the factions at Rome became more and more ruthless in their pusuit of control over the Republic. By this time, several generals had seized control of the city and imposed dictatorship only to die or relinquish power back to the Senate. Political violence was common and political assassination an accepted fact of life. Sadly, this was merely prelude to what was to come. In 46 BC, an internal dispute between power blocks exploded into the Roman Civil War. Julius Caesar had won widespread acclaim for his stunning conquest of Gaul (modern France), but the Senate was suspicious (rightly as it turned out) that he wanted to seize control of the Republic like other military strong men before him. It therefore sent orders for him to return to Rome. He obeyed... after a fashion. He crossed the Rubicon River which separated his assigned province from Italy where he was not allowed to command troops, and he came at the head of his army. While there was intense fighting, Julius Caesar emerged as the victor and established de facto dictatorship in the city even though he clothed himself in the trappings of respect for the Senate.
This proved merely a lull in the war, however. He was assassinated on the Ides of March (March 15th) 44 BC leading to a new round of battles. The faction of the assassins was defeated in Greece by Caesar's heir, Octavian, and his best friend, Marc Antony. However, their alliance did not outlast their "final" victory. Octavian had secured his father's place as leader of Rome, while Marc Antony, like any good friend, refused to let Caesar's mistress, the Egyptian queen Cleopatra grow cold in her bed. Antony and Cleopatra therefore made Alexandria their capital and waged the last battle of the Civil War against Octavian at sea; their defeat at the Battle of Actium secured Roman hegemony over Egypt and ended the war. With the suicide of Cleopatra, Queen of Egypt in 30 BC, the last Hellenistic monarch died leaving Rome in direct possession of all lands bordering the Mediterranean.
Octavian, triumphant and now unchallenged, returned to Rome where he restored the Republic, guaranteed the Senate its privileges, blah, blah, blah. The Romans were exhausted after years of civil war, and in typical Roman fashion, the Senate craved not freedom but order. They were desperate not to alienate him the way they had alienated Julius Caesar in 49 BC; they did not want another 20 years of civil wars. Octavian would make much in his propaganda of closing the doors to the temple of peace three times during his reign; this was a religious ceremony to celebrate the end of war which had only occured a few times in Roman history. However, it reassured his people that the "Republic" was back on solid ground, which was Augustus's most important ammunition against his detractors in the Senate who wanted to limit his power.
This is how he was able to get the Senate to accept his "modest demands", including lavishing him with praise and titles including his more familiar name, Caesar Augustus. 31 BC marks the end of the Roman Republic; Augustus effectively seized control and ruled Rome as a monarch. One of the new titles bestowed upon him was Imperator, effectively head of the armed forces; this word is the origin of the title, Emperor and the death of the Republic marks the beginning of Imperial Rome. The Senate knew they were destroying the Republic, but if that was the price of ending two decades of civil wars they were willing to pay it. It worked in a way; they guaranteed Rome not two decades but two centuries of almost constant civil war, political violence, and assassination. Good long-lived emperors became the rare exception to the constant string of assassination and coups. At it's most depressing, 69 AD was the year of the 4 emperors, a depth of futility that was extreme even for the Empire, but sadly indicative of the instability that was now a fundamental part of Roman society.
