Basic Chronology and Periods of Roman History
According to Roman tradition, Rome was founded as a monarchy. That monarchy, however, was not long-lived, and its history is overshadowed by myth and legend. Historians of Rome have most often divided its history into two major periods, based on the type of government that Rome had at the time: the Republic (from the late sixth century BCE to the late first century BCE) and the Empire (from the late first century BCE to the fall of the Western half of the empire in the late fifth century CE). Indeed, as seen in the writings of the Roman historian Tacitus, already as early as the late first century CE, Romans themselves thought of their history in terms of those two periods. The basic difference between the two periods is quite simple. During the period of the Republic, Rome was ruled by a Republican government, which distributed power, in theory, among all Roman citizens. In practice, this was really an aristocratic oligarchy. By contrast, under the Empire, Rome was under one ruler, the Emperor.
Recent research, however, has challenged the over-simplification of Roman history that can be implied by thinking of it as comprising just two periods. The work of Harriet Flower has shown that the Roman Republic is best conceived of as a series of Republics, each with distinct features. The work of Peter Brown, furthermore, has challenged the myth of the “decline and fall” of the Roman Empire, first popularized by Edward Gibbon, a nineteenth-century British historian of Rome. Brown has shown that as a result of the Christianization of the Roman world, Roman culture in the Late Empire was quite different from that in the earlier periods, yet it was very much a flourishing culture.
This chapter proceeds chronologically, sub-dividing both the Republic and the Empire into early and late periods, while also devoting some attention to certain thematic topics that are key to understanding each period.
