Timelines and Chronologies of the Rulers of the Roman Empire

Roman History Timeline > Roman Emperors

The period of the Roman Empire lasted for about 500 years before all that was left was the Byzantine Empire. The Byzantine period belongs to the Middle Ages. This site focuses on the period before Romulus Augustulus was removed from the imperial throne in A.D. 476. It starts with Julius Caesar's adopted heir, Octavian, better known as Augustus, or Caesar Augustus. Here you will find different lists of Roman emperors from Augustus to Romulus Augustulus, with dates. Some focus on the different dynasties or centuries. Some lists show the relationships between the centuries more visually than others. There is also a list that separates eastern and western rulers.

This was a period when the emperors were mostly assassinated and one emperor followed the next in rapid succession. The reforms of Diocletian and the tetrarchy put an end to the period of chaos. Here is a table showing the names of many of the emperors, their dates of rule, dates and place of birth, their ages at accession to the imperial throne, and the date and manner of their deaths.

The period of the Roman Empire, prior to the A.D. 476 Fall of Rome in the West, is often divided into an earlier period called the Principate and a later period called the Dominate. The Principate ends with the Tetrarchy of Diocletian and starts with Octavian (Augustus), although this timeline for the Principate starts with events leading to the replacement of the Republic with emperors and includes events in Roman history not directly connected with the emperors.
