Roman Emperors is a concise chronological guide to the emperors who ruled the Roman Empire. It covers the period from the establishment of the Empire by Augustus in 27 BCE to the abdication of Romulus Augustus in 476 CE, an event that marks the official end of the existence of the Roman Empire as a political entity in Western Europe. After a useful introduction to the late Republic and its transformation into the Empire, each of the eighty-five emperors customarily recognized as legitimate are presented in the order in which they reigned. This includes both Eastern and Western emperors for those periods where the empire was divided, and each one is illustrated. A useful glossary of technical terms is also provided.
