Culture of ancient Rome
The Roman Empire, at its height (c. 117 CE), was the most extensive political and social structure in western civilization. By 285 CE the empire had grown too vast to be ruled from the central government at Rome and so was divided by Emperor Diocletian into a Western and an Eastern Empire. The Roman Empire began when Augustus Caesar became the first emperor of Rome (31 BCE) and ended, in the west, when the last Roman emperor, Romulus Augustulus, was deposed by the Germanic King Odoacer (476 CE). In the east, it continued as the Byzantine Empire until the death of Constantine XI and the fall of Constantinople to the Ottoman Turks in 1453 CE. The influence of the Roman Empire on western civilization was profound in its lasting contributions to virtually every aspect of western culture.
History of Western civilization before AD 500
The slow decline of the Western Empire occurred over a period of roughly three centuries, culminating in 476, when Romulus Augustus, the last Emperor of the Western Roman Empire, was deposed by Odoacer, a Germanic chieftain. Some modern historians question the significance of this date, and not simply because Julius Nepos, the legitimate emperor recognized by the East Roman Empire, continued to live in Salona, Dalmatia, until he was assassinated in 480. More importantly, the Ostrogoths who succeeded considered themselves upholders of the direct line of Roman traditions and, as the historian Edward Gibbon noted, the Eastern Roman Empire continued until the Fall of Constantinople on May 29, 1453.
