Ioannes XXIII, By De Agostini, 1958–1963
Joannes or John ( la, Iohannes; died 425) was western Roman emperor from 423 to 425. On the death of the Emperor Honorius (15 August 423), Theodosius II, the remaining ruler of the House of Theodosius, hesitated in announcing his uncle's death. In the '' interregnum'', Honorius's patrician at the time of his death, Castinus, elevated Joannes as emperor. History Joannes was a ''primicerius notariorum'' or senior civil servant at the time of his elevation. Procopius praised him as "both gentle and well-endowed with sagacity and thoroughly capable of valorous deeds." Unlike the Theodosian emperors, he tolerated all Christian sects and even the pagans. From the beginning, his control over the empire was insecure. In Gaul, his praetorian prefect was slain at Arles in an uprising of the soldiery there. And Bonifacius, ''comes'' of the Diocese of Africa, held back the grain fleet destined to Rome. "The events of Johannes' reign are as shadowy as its origins," writes John Mat ...

Solidus (coin)
The ''solidus'' (Latin 'solid';  ''solidi'') or nomisma ( grc-gre, νόμισμα, ''nómisma'',  'coin') was a highly pure gold coin issued in the Late Roman Empire and Byzantine Empire. Constantine I, Constantine introduced the coin, and its weight of about 4.5 grams remained relatively constant for seven centuries. In the Byzantine Empire, the solidus or nomisma remained a highly pure gold coin until the 11th century, when several Byzantine Empire, Byzantine list of Byzantine emperors, emperors began to strike the coin with less and less gold. The nomisma was finally abolished by Alexius I in 1092, who replaced it with the hyperpyron, which also came to be known as a "bezant". The Byzantine solidus also inspired the originally slightly less pure Dinar (coin), dinar issued by the Muslim Caliphate. In Western Europe, the solidus was the main gold coin of commerce from late Roman times to Pepin the Short's Carolingian Renaissance#Carolingian currency, currency reform, wh ...

Praetorian Prefect
The praetorian prefect ( la, praefectus praetorio, el, ) was a high office in the Roman Empire. Originating as the commander of the Praetorian Guard, the office gradually acquired extensive legal and administrative functions, with its holders becoming the Emperor's chief aides. Under Constantine I, the office was much reduced in power and transformed into a purely civilian administrative post, while under his successors, territorially-defined praetorian prefectures emerged as the highest-level administrative division of the Empire. The prefects again functioned as the chief ministers of the state, with many laws addressed to them by name. In this role, praetorian prefects continued to be appointed by the Eastern Roman Empire (and the Ostrogothic Kingdom) until the reign of Heraclius in the 7th century AD, when wide-ranging reforms reduced their power and converted them to mere overseers of provincial administration. The last traces of the prefecture disappeared in the Byzantine Em ...

Huns
The Huns were a nomadic people who lived in Central Asia, the Caucasus, and Eastern Europe between the 4th and 6th century AD. According to European tradition, they were first reported living east of the Volga River, in an area that was part of Scythia at the time; the Huns' arrival is associated with the migration westward of an Iranian people, the Alans. By 370 AD, the Huns had arrived on the Volga, and by 430, they had established a vast, if short-lived, dominion in Europe, conquering the Goths and many other Germanic peoples living outside of Roman borders and causing many others to flee into Roman territory. The Huns, especially under their King Attila, made frequent and devastating raids into the Eastern Roman Empire. In 451, they invaded the Western Roman province of Gaul, where they fought a combined army of Romans and Visigoths at the Battle of the Catalaunian Fields, and in 452, they invaded Italy. After the death of Attila in 453, the Huns ceased to be a major thr ...

Aetius (general)
Aetius (also spelled Aëtius; ; 390 – 454) was a Roman general and statesman of the closing period of the Western Roman Empire. He was a military commander and the most influential man in the Empire for two decades (433454). He managed policy in regard to the attacks of barbarian federates settled throughout the West. Notably, he mustered a large Roman and allied (''foederati'') army in the Battle of the Catalaunian Plains, ending a devastating invasion of Gaul by Attila in 451, though the Hun and his subjugated allies still managed to invade Italy the following year, an incursion best remembered for the ruthless Sack of Aquileia and the intercession of Pope Leo I. Aetius has often been called, "Last of the Romans". Edward Gibbon refers to him as "the man universally celebrated as the terror of Barbarians and the support of the Republic" for his victory at the Catalaunian Plains. J.B Bury notes, "That he was the one prop and stay of the Western Empire during his life time ...

She was List of Visigothic queens, queen consort to Ataulf, king of the Visigoths from 414 until his death in 415, briefly empress consort to Constantius III in 421, and managed the government administration as a regent during the early reign of Valentinian III, until her death.

Caesar (title)
Caesar ( English  Caesars; Latin  ''Caesares''; in Greek: ''Kaîsar'') is a title of imperial character. It derives from the ''cognomen'' of Julius Caesar, a Roman dictator. The change from being a familial name to a title adopted by the Roman emperors can be traced to AD 68, following the fall of the Julio–Claudian dynasty. Origins The first known individual to bear the ''cognomen'' of "Caesar" was Sextus Julius Caesar, who is likewise believed to be the common ancestor of all subsequent Julii Caesares. Sextus' great-grandson was the dictator Gaius Julius Caesar. After he seized control of the Roman Republic following his war against the Senate, he adopted the title of ''dictator perpetuo'' ("dictator in perpetuity"), a title he only held for about a month before he was assassinated in 44 BC. Julius Caesar's death did not lead to the restoration of the Republic, and instead led to the rise of the Second Triumvirate, composed by three dictators including Ju ...

Eastern Empire
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, 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 fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years 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 Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome ...

Ravenna
Ravenna ( , , also ; rgn, Ravèna) is the capital city of the Province of Ravenna, in the Emilia-Romagna region of Northern Italy. It was the capital city of the Western Roman Empire from 408 until its collapse in 476. It then served as the capital of the Ostrogothic Kingdom until it was re-conquered in 540 by the Byzantine Empire. Afterwards, the city formed the centre of the Byzantine Exarchate of Ravenna until the last exarch was executed by the Lombards in 751. Although it is an inland city, Ravenna is connected to the Adriatic Sea by the Candiano Canal. It is known for its well-preserved late Roman and Byzantine architecture, with eight buildings comprising the UNESCO World Heritage Site "Early Christian Monuments of Ravenna". History The origin of the name ''Ravenna'' is unclear. Some have speculated that "Ravenna" is related to "Rasenna" (or "Rasna"), the term that the Etruscan civilization, Etruscans used for themselves, but there is no agreement on this point. Ancien ...

Gens Anicia
The gens Anicia (or the Anicii) was a plebeian family at ancient Rome, mentioned first towards the end of the fourth century BC. The first of the Anicii to achieve prominence under the Republic was Lucius Anicius Gallus, who conducted the war against the Illyrii during the Third Macedonian War, in 168 BC. A noble family bore this name in the imperial era, and may have been descended from the Anicii of the Republic.''Dictionary of Greek and Roman Biography and Mythology'', William Smith, Editor. Origin The Anicii may have been from the Latin town of Praeneste. The earliest of the family to hold any curule magistracy at Rome bore the surname ''Praenestinus''. Praenomina The Anicii are known to have used the praenomina ''Lucius, Quintus, Marcus, Gnaeus, Titus,'' and ''Gaius''. Branches and cognomina The only major branch of the family during the Republic used the cognomen ''Gallus'', which may refer to a cock, or to a Gaul. The surname ''Praenestinus'', found in earlier tim ...

Olympiodorus Of Thebes
Olympiodorus of Thebes ( grc-gre, Ὀλυμπιόδωρος ὁ Θηβαῖος; born c. 380, fl. c. 412–425 AD) was a Roman historian, poet, philosopher and diplomat of the early fifth century. He produced a ''History'' in twenty-two volumes, written in Greek, dedicated to the Emperor Theodosius II, detailing events in the Western Roman Empire between 407 and 425. His friends included philosophers, provincial governors and rhetoricians. He made several journeys in an official capacity, accompanied for twenty years by a parrot. He was a "convinced but discreet" pagan, who flourished in a Christian court, and whose work influenced several subsequent historians, including writers of ecclesiastical history. Life Olympiodorus was born between 365 and 380 in Thebes (modern Luxor, Egypt), in the Roman province of Thebaïd, into a curial family. Thebes at that point was a flourishing centre of literary learning, and a cradle of politicians and public figures. He received a classical e ...

Diocese Of Africa
The Diocese of Africa ( la, Dioecesis Africae) was a diocese of the later Roman Empire, incorporating the provinces of North Africa, except Mauretania Tingitana. Its seat was at Carthage, and it was subordinate to the Praetorian prefecture of Italy. The diocese included the provinces of Africa proconsularis (also known as Zeugitana), Byzacena, Mauretania Sitifensis, Mauretania Caesariensis, Numidia Cirtensis, Numidia Militiana and Tripolitania. In current geo-political terms, the Diocese of Africa included the entire coastline of Tunisia, Algeria with some mountainous hinterlands, plus the western half of Libya's coastline. The diocese existed from the time of the Diocletianian and Constantinian reforms in the last years of the 3rd century until it was overrun by the Vandals in the 430s. The provincial organization were retained under the Vandals, and after their defeat and the reconquest of Africa by the Eastern Roman Empire in the Vandalic War, they were grouped anew, but th ...
