the Greek city Pergamum to the Roman people. He also attempted to stand for tribune a second time, partly because he was afraid of persecution by the Senate after he stepped down. This gave the senators the pretext to charge that Tiberius was trying to declare himself king. He and his supporters were attacked, and many were killed. Tiberius Gracchus himself was one of the first to fall, though his death would not solve the problem, and others would attempt to reform the distribution of land and other aspects of Roman economy and society. Many would meet a similar fate. Tiberius Gracchus’s brother Gaius, for example, was also murdered by landowners, after he took the mantle from his brother.
These tensions would surface again periodically during the next century—for example, leading to the “Social War” between 91 BC and 87 BC. The aggressive defender of the senatorial interests, Lucius Cornelius Sulla, not only viciously suppressed the demands for change but also severely curtailed the powers of the plebeian tribune. The same issues would also be a central factor in the support that Julius Caesar received from the people of Rome in his fight against the Senate.
The political institutions forming the core of the Roman Republic were overthrown by Julius Caesar in 49 BC when he moved his legion across the Rubicon, the river separating the Roman provinces of Cisalpine Gaul from Italy. Rome fell to Caesar, and another civil war broke out. Though Caesar was victorious, he was murdered by disgruntled senators, led by Brutus and Cassius, in 44 BC. The Roman Republic would never be re-created. A new civil war broke out between Caesar’s supporters, particularly Mark Anthony and Octavian, and his foes. After Anthony and Octavian won, they fought each other, until Octavian emerged triumphant in the battle of Actium in 31 BC. By the following year, and for the next forty-five years, Octavian, known after 28 BC as Augustus Caesar, ruled Rome alone. Augustus created the Roman Empire, though he preferred the title princep, a sort of “first among equals,” and called the regime the Principate. Map 11 shows the Roman Empire at its greatest extent in 117 AD. It also includes the river Rubicon, which Caesar so fatefully crossed.
It was this transition from republic to principate, and later naked empire, that laid the seeds of the decline of Rome. The partially inclusive political institutions, which had formed the basis for the economic success, were gradually undermined. Even if the Roman Republic created a tilted playing field in favor of the senatorial class and other wealthy Romans, it was not an absolutist regime and had never before concentrated so much power in one position. The changes unleashed by Augustus, as with the Venetian Serrata, were at first political but then would have significant economic consequences. As a result of these changes, by the fifth century AD the Western Roman Empire, as the West was called after it split from the East, had declined economically and militarily, and was on the brink of collapse.
… ROMAN VICES
Flavius Aetius was one of the larger-than-life characters of the late Roman Empire, hailed as “the last of the Romans” by Edward Gibbon, author of The Decline and Fall of the Roman Empire. Between AD 433 and 454, until he was murdered by the emperor Valentinian III, Aetius, a general, was probably the most powerful person in the Roman Empire. He shaped both domestic and foreign policy, and fought a series of crucial battles against the barbarians, and also other Romans in civil wars. He was unique among powerful generals fighting in civil wars in not seeking the emperorship himself. Since the end of the second century, civil war had become a fact of life in the Roman Empire. Between the death of Marcus Aurelius in AD 180 until the collapse of the Western Roman Empire in AD 476, there was hardly a decade that did not see a civil war or a palace coup against an emperor. Few emperors died of natural causes or in battle. Most were murdered by usurpers or their own troops.
Aetius’s career illustrates the changes from Roman Republic and early Empire to the late Roman Empire. Not only did his involvement in incessant civil wars and his power in every aspect of the empire’s business contrast with the much more limited power of generals and senators during earlier periods, but it also highlights how the fortunes of Romans changed radically in the intervening centuries in other ways.
