Byzantine EmpireThe Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fall of the Western Roman Empire in the 5th century AD and continued to exist until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in the Mediterranean world.
LactantiusLucius Caecilius Firmianus signo Lactantius (c. 250 – c. 325) was an early Christian author who became an advisor to Roman emperor Constantine I, guiding his Christian religious policy in its initial stages of emergence, and a tutor to his son Crispus. His most important work is the Institutiones Divinae ("The Divine Institutes"), an apologetic treatise intended to establish the reasonableness and truth of Christianity to pagan critics. He is best known for his apologetic works, widely read during the Renaissance by humanists, who called Lactantius the "Christian Cicero".
KaiserKaiser is the German word for "emperor" (female, Kaiserin). In general, the German title in principle applies to rulers anywhere in the world above the rank of king (König). In English, the (untranslated) word Kaiser is mainly applied to the emperors of the unified German Empire (1871–1918) and the emperors of the Austrian Empire (1804–1918). During the First World War, anti-German sentiment was at its zenith; the term Kaiser—especially as applied to Wilhelm II, German Emperor—thus gained considerable negative connotations in English-speaking countries.
Sasanian EmpireThe Sasanian Empire (səˈsɑːniən,_səˈseɪniən), officially known as Eranshahr ("Land/Empire of the Iranians"), was the last Iranian empire before the early Muslim conquests of the 7th–8th centuries AD. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).
LiciniusValerius Licinianus Licinius (Greek: Λικίνιος; c. 265 – 325) was Roman emperor from 308 to 324. For most of his reign he was the colleague and rival of Constantine I, with whom he co-authored the Edict of Milan, AD 313, that granted official toleration to Christians in the Roman Empire. He was finally defeated at the Battle of Chrysopolis (AD 324), and was later executed on the orders of Constantine I. Born to a Dacian peasant family in Moesia Superior, Licinius accompanied his close childhood friend, the future emperor Galerius, on the Persian expedition in 298.
Rum (endonym)Rūm (روم ruːm, collective; singulative: رومي Rūmī ˈruːmiː; plural: أروام Arwām ʔarˈwaːm; روم Rum or رومیان Rumiyān, singular رومی Rumi; Rûm or Rûmîler, singular Rûmî), also romanized as Roum, is a derivative of the Aramaic (rhπmÈ) and Parthian (frwm) terms, ultimately derived from Greek Ῥωμαῖοι (Rhomaioi, literally 'Romans'). Both terms are endonyms of the pre-Islamic inhabitants of Anatolia, the Middle East and the Balkans and date to when those regions were parts of the Eastern Roman Empire.
Praetorian GuardThe Praetorian Guard (Latin: cohortēs praetōriae) was an elite unit of the Imperial Roman army that served as personal bodyguards and intelligence agents for the Roman emperors. During the Roman Republic, the Praetorian Guards were escorts for high-ranking political officials (senators and procurators) and were bodyguards for the senior officers of the Roman legions. In 27 BC, after Rome's transition from republic to empire, the first emperor of Rome, Augustus, designated the Praetorians as his personal security escort.
Roman naming conventionsOver the course of some fourteen centuries, the Romans and other peoples of Italy employed a system of nomenclature that differed from that used by other cultures of Europe and the Mediterranean Sea, consisting of a combination of personal and family names. Although conventionally referred to as the tria nomina, the combination of praenomen, nomen, and cognomen that have come to be regarded as the basic elements of the Roman name in fact represent a continuous process of development, from at least the seventh century BC to the end of the seventh century AD.
Roman emperorThe Roman emperor was the ruler and monarchial head of state of the Roman Empire during the imperial period, starting with the granting of the title augustus to Octavian in 27 BC. The emperors used a variety of different titles throughout history. Often when a given Roman is described as becoming emperor in English, it reflects his taking of the title augustus and later basileus. Another title often used was caesar, used for heirs-apparent, and imperator, originally a military honorific.
ElagabalusMarcus Aurelius Antoninus (born Sextus Varius Avitus Bassianus, 204 – 11/12 March 222), better known by his nicknames Elagabalus (ˌɛləˈgæbələs, ) and Heliogabalus (ˌhiːliə-,_-lioʊ- ), was Roman emperor from 218 to 222, while he was still a teenager. His short reign was conspicuous for sex scandals and religious controversy. A close relative to the Severan dynasty, he came from a prominent Arab family in Emesa (Homs), Syria, where since his early youth he served as head priest of the sun god Elagabal.
