Byzantine Emperors
This is a list of the Emperors of the late Eastern Roman Empire, called Byzantine.
The title of all Emperors listed preceding Heraclius was officially Augustus, although various other titles such as Dominus were used as well. For official purposes, their names were preceded by Imperator Caesar Flavius and followed by Augustus. Following Heraclius, the title became the Greek Basileus (Gr. Βασιλευς), which had formerly meant "king" but now was used in place of Augustus. Other (and to Roman minds, lesser) kings were titled by the neologism Rigas (Gr. Ρήγας;, from the Lat. "Rex"). Autokrator (Gr. Αυτοκράτωρ;) was also frequently used, along with a plethora of more hyperbolic titles - with grandiloquence typically in inverse proportion to actual power, - including Kosmokrator ("Master of the Universe") and Chronokrator ("Lord of All Time"). The emperors of the 15th century alone were occasionally self-styled as Basileus ton Hellinon, "Emperor of the Greeks."
[Note: See also the term "Byzantine" with regard to the late Roman Empire. This list begins with Constantine the Great, the first Christian emperor reigning from Constantinople, although Diocletian before him had ruled from Nicaea and replaced the pseudorepublican trappings of the office with a straightforward autocracy and Heraclius I after him replaced Latin with Greek and began the restructuring of the Empire into themata.
