Dominate
The Dominate, also known as the late Roman Empire, is the despotic form of imperial government of the late Roman Empire. It followed the earlier period known as the Principate. Until the empire was reunited in 313, this phase is more often called the Tetrarchy. It may begin with the commencement of the reign of Diocletian in AD 284, following the Third Century Crisis of AD 235–284, and end in the west with the fall of the Western Roman Empire in AD 476, while in the Eastern Roman Empire its end is disputed, with the majority of opinions placing it around the transition between the Justinian and Heraclian dynasties, between the years 565 and 641. In form, the Dominate is considered to have been more authoritarian, less collegial and more bureaucratic than the Principate from which it emerged.
