Marcus Aurelius Severus Alexander, also known as Alexander Severus, was a Roman emperor, who reigned from 222 until 235. He was the last emperor from the Severan dynasty. He succeeded his slain cousin Elagabalus in 222. Alexander himself was eventually assassinated, and his death marked the beginning of the events of the Crisis of the Third Century, which included nearly fifty years of civil war, foreign invasion, and the collapse of the monetary economy.
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 junior colleagues and designated successors, the caesares. This marked the end of the Crisis of the Third Century.
Year 235 (CCXXXV) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Severus and Quintianus. The denomination 235 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
The 230s decade ran from January 1, 230, to December 31, 239.
Marcus Aurelius Valerius Maxentius 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.
Gordian I was Roman emperor for 22 days with his son Gordian II in 238, the Year of the Six Emperors. Caught up in a rebellion against the Emperor Maximinus Thrax, he was defeated by forces loyal to Maximinus, and he committed suicide after the death of his son.
Legio II Parthica was a legion of the Imperial Roman army founded in AD 197 by the emperor Septimius Severus, for his campaign against the Parthian Empire, hence the cognomenParthica. The legion was still active in the beginning of the 5th century. The legion's symbol was a centaur.
Marcus Clodius Pupienus Maximus was Roman emperor with Balbinus for 99 days in 238, during the Year of the Six Emperors. The sources for this period are scant, and thus knowledge of the emperor is limited. In most contemporary texts he is referred to by his cognomen "Maximus" rather than by his second nomen Pupienus.
Herodian or Herodianus of Syria, sometimes referred to as "Herodian of Antioch", was a minor Roman civil servant who wrote a colourful history in Greek titled History of the Empire from the Death of Marcus in eight books covering the years 180 to 238. His work is not considered entirely reliable, although his less biased account of Elagabalus may be more useful than that of Cassius Dio. Herodian himself may have been a Syrian, though he appears to have lived for a considerable period of time in Rome, possibly without holding any public office. From his extant work, it seems that he was still living at an advanced age during the reign of Gordianus III, who ascended the throne in 238. Beyond this, nothing is known of his life.
Thysdrus was a Carthaginian town and Roman colony near present-day El Djem, Tunisia. Under the Romans, it was the center of olive oil production in the provinces of Africa and Byzacena and was quite prosperous. The surviving amphitheater is a World Heritage Site.
Taurinius was a Roman usurper who revolted against Severus Alexander in 232 AD. He was declared emperor by the legions stationed in Roman Mesopotamia when they rebelled, due to the invasion of the Sassanids in 229 AD. His revolt was swiftly crushed by Alexander, in late summer of 232 AD, and he drowned in the Euphrates while attempting to flee to Sassanid territory.
Gaius Petronius Magnus was a senator of consular rank and a Roman usurper. After the death of Emperor Severus Alexander there was much ill-feeling in the Senate about the elevation of Maximinus Thrax to the throne. A group of officers and senators under the leadership of Magnus plotted to overthrow Maximinus. Their plan was to have soldiers destroy the bridge over the river Rhine, after Maximinus had brought the army across during his campaign against the Germans. Maximinus would be left stranded on the north bank of the Rhine, at the mercy of the Germans. Before it was realized, the plan was discovered and all conspirators executed.
Gnaea Seia Herennia Sallustia Barbia Orbiana, usually known as Sallustia Orbiana, was a third century Roman empress, with the title of Augusta as the wife of Severus Alexander from AD 225 to 227. The emperor married her in late 225, following the death of his grandmother. Severus was around sixteen years of age at this time. She was known for her beauty, which was captured in multiple works of art. Possibly a victim of the jealousy of Julia Mamaea, the emperor's mother, Orbiana was divorced and exiled to Libya in 227.
Titus is one of the Thirty Tyrants, a list of Roman usurpers compiled by the author(s) of the often unreliable Historia Augusta. Titus was said to have revolted against Maximinus Thrax, a Roman Emperor who ruled 235–238, after the revolt of Magnus. It is now believed that his biography is fictitious, and that he may be based on person named Quartinus mentioned by the historian Herodian.
Severan art is art production by the Roman Empire under the Severan dynasty, usually taken as running from 193 to 235, through the emperors Septimius Severus, Caracalla, Heliogabalus and Alexander Severus. Official Roman art of the military anarchy which followed, ending in 253 with Gallienus, has no character of its own and so can be seen as a continuation of Severan art, and so that art can be seen as running for the whole first half of the 3rd century.
The civil wars of the Tetrarchy were a series of conflicts between the co-emperors of the Roman Empire, starting from 306 AD with the usurpation of Maxentius and the defeat of Severus to the defeat of Licinius at the hands of Constantine I in 324 AD.
Gaius Julius Verus Maximinus "Thrax" was a Roman emperor from 235 to 238.
The Conference of Carnuntum was a military conference held on November 11, 308 in the city of Carnuntum, which at the time was located in the province of Pannonia Prima. It was convened by the senior emperor of the East (Augustus) Galerius as a way to settle the dispute over the title of Augustus of the West and, consequently, to cease the ongoing conflicts since the previous year when he, and before that Severus II', invaded the Italy of Maxentius (r306-312) and Maximian. Present at the conference were Diocletian, who had been retired since 305, and Maximian.
