Dominate vs. Predominate — What's the Difference?

The Dominate is the name sometimes given to the "despotic" later phase of imperial government, following the earlier period known as the "Principate", in the ancient Roman Empire. This phase is more often called the Tetrarchy at least until 313 when the empire was reunited.It may begin with the commencement of the reign of Diocletian in AD 284, following the Third Century Crisis of AD 235–284, and to end in the west with the collapse of the Western Empire in AD 476, while in the east its end is disputed, as either occurring at the close of the reign of Justinian I (AD 565) or of Heraclius (AD 641).
