Tetrarchy
The Tetrarchy was the system instituted by Roman emperor Diocletian in 293 AD to govern the ancient Roman Empire by dividing it between two emperors, the '' augusti'', and their juniors colleagues and designated successors, the '' caesares''. This marked the end of the Crisis of the Third Century. Initially Diocletian chose Maximian as his ''caesar'' in 285, raising him to co-''augustus'' the following year; Maximian was to govern the western provinces and Diocletian would administer the eastern ones. The role of the ''augustus'' was likened to Jupiter, while his ''caesar'' was akin to Jupiter's son Hercules. Galerius and Constantius were appointed ''caesares'' in March 293. Diocletian and Maximian retired on 1 May 305, raising Galerius and Constantius to the rank of ''augustus''. Their places as ''caesares'' were in turn taken by Valerius Severus and Maximinus Daza. The orderly system of two senior and two junior rulers endured until Constantius died in July 306, and his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portrait Of The Four Tetrarchs
The Portrait of the Four Tetrarchs is a porphyry sculpture group of four Roman emperors dating from around 300 AD. The sculptural group has been fixed to a corner of the façade of St Mark's Basilica in Venice, Italy since the Middle Ages. It probably formed part of the decorations of the Philadelphion in Constantinople, and was removed to Venice in 1204 or soon after. ''Spolia'' from the Fourth Crusade, the statues were originally designed as two separate sculptures, each consisting of a pair of armoured late Roman emperors embracing one another. The paired statues stand on plinths supported by a console of the same stone, and their backs are engaged in the remains of large porphyry columns to which the statues were once attached, carved all of a piece. The columns no longer exist, and one emperor pair is missing part of the plinth and an emperor's foot, which has been found in Istanbul. One statue pair has been sliced vertically and is missing a large portion of the right-ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maxentius
Marcus Aurelius Valerius Maxentius (c. 283 – 28 October 312) was a Roman emperor, who reigned from 306 until his death in 312. Despite ruling in Italy and North Africa, and having the recognition of the Senate in Rome, he was not recognized as a legitimate emperor by his fellow emperors. He was the son of former Emperor Maximian and the son-in-law of Emperor Galerius. The latter part of his reign was preoccupied with civil war, allying with Maximinus against Licinius and Constantine I, Constantine. The latter defeated him at the Battle of the Milvian Bridge in 312, where Maxentius, with his army in flight, purportedly perished by drowning in the Tiber river. Maxentius was the last emperor to permanently reside in Rome. He attempted to embellish, restore and improve the ancient capital, carrying out important building works, including the Temple of Romulus, Temple of the Divine Romulus (dedicated to his deceased son), the Basilica of Maxentius, which was completed by Const ...

Constantius Chlorus
Flavius Valerius Constantius "Chlorus" ( – 25 July 306), also called Constantius I, was Roman emperor from 305 to 306. He was one of the four original members of the Tetrarchy established by Diocletian, first serving as caesar from 293 to 305 and then ruling as augustus until his death. Constantius was also father of Constantine the Great, the first Christian emperor of Rome. The nickname Chlorus () was first popularized by Byzantine-era historians and not used during the emperor's lifetime. After his re-conquering of Roman Britain, he was given the title 'Redditor Lucis Aeternae', meaning 'The Restorer of Eternal Light'. Of humble origin, Constantius had a distinguished military career and rose to the top ranks of the army. Around 289 he set aside Helena, Constantine's mother, to marry a daughter of Emperor Maximian, and in 293 was added to the imperial college by Maximian's colleague, Diocletian. Assigned to rule Gaul, Constantius defeated the usurper Carausius there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximian
Maximian ( la, Marcus Aurelius Valerius Maximianus; c. 250 – c. July 310), nicknamed ''Herculius'', was Roman emperor from 286 to 305. He was ''Caesar'' from 285 to 286, then ''Augustus'' from 286 to 305. He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In late 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he launched a scorched earth campaign deep into Alamannic territory in 288, refortifying the frontier. The man he appointed to police the Channel shores, Carausius, rebelled in 286, causing the secession of Britain and northwestern Gaul. Maximian failed to oust Carausius, and his invasion fleet was destroyed by storms in 289 or 290. Maximian's subordinate, Constantius, campaigned against Ca ...

Diocletian
Diocletian (; la, Gaius Aurelius Valerius Diocletianus, grc, Διοκλητιανός, Diokletianós; c. 242/245 – 311/312), nicknamed ''Iovius'', was Roman emperor from 284 until his abdication in 305. He was born Gaius Valerius Diocles to a family of low status in the Roman province of Dalmatia. Diocles rose through the ranks of the military early in his career, eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name Diocletianus. The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus. Diocletian's reign stabilized the empire and ended the Crisis of the Third Century. He appointed fellow officer Maximian as ''Augustus'', co-emperor, in 286.

Eastern Roman 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 a ...

Fall Of The Western Roman Empire
The fall of the Western Roman Empire (also called the fall of the Roman Empire or the fall of Ancient Rome, Rome) was the loss of central political control in the Western Roman Empire, a process in which the Empire failed to enforce its rule, and its vast territory was divided into several successor Polity, polities. The Roman Empire lost the strengths that had allowed it to exercise effective control over its Western Roman province, provinces; modern historians posit factors including the effectiveness and numbers of the Late Roman army, army, the health and numbers of the Roman population, the strength of the Roman economy, economy, the competence of the Roman emperor, emperors, the internal struggles for power, the religious changes of the period, and the efficiency of the civil administration.

Battle Of Chrysopolis
The Battle of Chrysopolis was fought on 18 September 324 at Chrysopolis (modern Üsküdar), near Chalcedon (modern Kadıköy), between the two Roman emperors Constantine I and Licinius. The battle was the final encounter between the two emperors. After his navy's defeat in the Battle of the Hellespont, Licinius withdrew his forces from the city of Byzantium across the Bosphorus to Chalcedon in Bithynia. Constantine followed, and won the subsequent battle. This left Constantine as the sole emperor, ending the period of the Tetrarchy. Background The navy of Licinius had suffered a catastrophic defeat at the Battle of the Hellespont. His admiral, Abantus, had been outfought by Constantine's son, the caesar Crispus, despite the latter's distinctly smaller fleet. Following this naval victory, Constantine crossed over to Asia Minor. An army, under the command of Licinius' newly appointed co-emperor Martinian, was guarding the coast at Lampsacus on the Hellespont. Constantine ...

Constantius II
Constantius II (Latin: ''Flavius Julius Constantius''; grc-gre, Κωνστάντιος; 7 August 317 – 3 November 361) was Roman emperor from 337 to 361. His reign saw constant warfare on the borders against the Sasanian Empire and Germanic peoples, while internally the Roman Empire went through repeated civil wars, court intrigues, and usurpations. His religious policies inflamed domestic conflicts that would continue after his death. Constantius was a son of Constantine the Great, who elevated him to the imperial rank of ''Caesar'' on 8 November 324 and after whose death Constantius became ''Augustus'' together with his brothers, Constantine II and Constans on 9 September 337. He promptly oversaw the massacre of his father-in-law, an uncle, and several cousins, consolidating his hold on power. The brothers divided the empire among themselves, with Constantius receiving Greece, Thrace, the Asian provinces, and Egypt in the east. For the following decade a costly and inco ...

Constantine II (emperor)
Constantine II ( la, Flavius Claudius Constantinus; February 316 – 340) was Roman emperor from 337 to 340. Son of Constantine the Great and co-emperor alongside his brothers, his attempt to exert his perceived rights of primogeniture led to his death in a failed invasion of Italy in 340. Career The eldest son of Constantine the Great and Fausta, Constantine II was born in Arles in February 316 and raised as a Christian. Caesar On 1 March 317, he was made Caesar. In 323, at the age of seven, he took part in his father's campaign against the Sarmatians. At age ten, he became commander of Gaul, following the death of his half-brother Crispus. An inscription dating to 330 records the title of ''Alamannicus'', so it is probable that his generals won a victory over the Alamanni. His military career continued when Constantine I made him field commander during the 332 campaign against the Goths.
