Marcus Aurelius Severus Alexander, also known as Alexander Severus, was Roman emperor from 222 until 235. The last emperor from the Severan dynasty, he succeeded his slain cousin Elagabalus in 222, at the age of 13. 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 Severan dynasty, sometimes called the Septimian dynasty, was an Ancient Roman imperial dynasty that ruled the Roman Empire between 193 and 235, during the Roman imperial period. The dynasty was founded by the emperor Septimius Severus, who rose to power after the Year of the Five Emperors as the victor of the civil war of 193–197, and his wife, Julia Domna. After the short reigns and assassinations of their two sons, Caracalla and Geta, who succeeded their father in the government of the empire, Julia Domna's relatives themselves assumed power by raising Elagabalus and then Severus Alexander to the imperial office.
The 220s decade ran from January 1, 220, to December 31, 229.
Year 227 (CCXXVII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Senecio and Fulvius. The denomination 227 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.
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.
Gordian II was Roman emperor with his father Gordian I in 238 AD, the Year of the Six Emperors. Seeking to overthrow Maximinus Thrax, he died in battle outside Carthage. Since he died before his father, Gordian II likely had the shortest reign of any Roman emperor, at 22 days, possibly second only to Quintillus, who, according to some sources, reigned for just 17 days.
Marcus Didius Julianus was Roman emperor from March to June 193, during the Year of the Five Emperors. Julianus had a promising political career, governing several provinces, including Dalmatia and Germania Inferior, and defeated the Chauci and Chatti, two invading Germanic tribes. He was even appointed to the consulship in 175 along with Pertinax as a reward, before being demoted by Commodus. After this demotion, his early, promising political career languished.
Marcus Aurelius Claudius Quintillus was a short-lived Roman emperor. He was a brother of Emperor Claudius Gothicus, whom he succeeded after Claudius' death in 270. Quintillus' claim to be emperor was challenged by Aurelian, who was proclaimed emperor by the legions he commanded. Quintillus' reign only lasted a few weeks. Different sources report his cause of death as murder by his own soldiers, in battle with Aurelian, or by suicide.
Julia Maesa was a member of the Severan dynasty of the Roman Empire who was the grandmother of emperors Elagabalus and Severus Alexander, elder sister of empress Julia Domna, and mother of Julia Soaemias and Julia Mamaea. She wielded influence during the reigns of her grandsons as Augusta of the Empire from 218 to her death, especially on their elevation to emperors.
Julia Soaemias Bassiana was a Syrian noblewoman and the mother of Roman emperor Elagabalus, who ruled over the Roman Empire from 218 to 222. She was one of his chief advisors, initially with the support and accompaniment of her mother Julia Maesa. She and her mother guided the young emperor until growing unrest and a family division led to her son's replacement by her nephew Severus Alexander. Julia Soaemias was killed along with her son by the Praetorian Guard.
Julia Avita Mamaea or Julia Mamaea was a Christian Syrian noble woman and member of the Severan dynasty. She was the mother of Roman emperor Alexander Severus and remained one of his chief advisors throughout his reign. She was killed in 235 by rebel soldiers alongside her son.
Diadumenian was the son of the Roman emperor Macrinus and served as his co-ruler for a brief time in 218. His mother, Macrinus' wife, is called Nonia Celsa in the unreliable Historia Augusta, though this name may have been fictional. Diadumenian became caesar in May 217, shortly after his father's accession to the imperial throne. Elagabalus, a relative of the recently deceased Caracalla, revolted in May of the following year, and Diadumenian was elevated to co-emperor. After Macrinus was defeated in the Battle of Antioch on 8 June 218, Diadumenian was sent to the court of Artabanus IV of Parthia to ensure his safety; however, he was captured and executed along the way. After his death and that of his father, the Senate declared both of them enemies of Rome and had their names struck from records and their images destroyed — a process known in modern scholarship as damnatio memoriae.
Gaius Pius Esuvius Tetricus was the emperor of the Gallic Empire from 271 to 274 AD. He was originally the praeses (governor) of Gallia Aquitania and became emperor after the murder of Emperor Victorinus in 271, with the support of Victorinus's mother, Victoria. During his reign, he faced external pressure from Germanic raiders, who pillaged the eastern and northern parts of his empire, and the Roman Empire, from which the Gallic Empire had seceded. He also faced increasing internal pressure, which led him to declare his son, Tetricus II, caesar in 273 and possibly co-emperor in 274, although this is debated. The Roman emperor Aurelian invaded in 273 or 274, leading to the Battle of Châlons, at which Tetricus surrendered. Whether this capitulation was the result of a secret agreement between Tetricus and Aurelian or necessary after his defeat is debated. Aurelian spared Tetricus, and even made him a senator and corrector (governor) of Lucania et Bruttium. Tetricus died of natural causes a few years after 274.
Aureolus was a Roman military commander during the reign of Emperor Gallienus before he attempted to usurp the Roman Empire. After turning against Gallienus, Aureolus was killed during the political turmoil that surrounded the Emperor's assassination in a conspiracy orchestrated by his senior officers. Aureolus is known as one of the Thirty Tyrants and is referenced in ancient sources including the Historia Augusta, Zonaras' epitome and Zosimus' Historia Nova.
Lucius Seius Herennius Sallustius was a Roman usurper in 227. He was a son of Seius and his wife Herennia Orbiana, and paternal grandson of Publius Seius Fuscianus.
Ulpia Severina was Roman empress as the wife of Roman emperor Aurelian from c. 270 to 275. Severina is unmentioned in surviving literary sources and known only from coinage and inscriptions and as a result, very little is known about her. Her nomen Ulpia suggests that she may have been related either to Emperor Trajan or the usurper Laelianus, as they share the same nomen, and perhaps from Dacia, where the name was common. It is not known when she married Aurelian, but it might have been before he became emperor. She was probably proclaimed Augusta in the autumn of 274.
The gens Septimia was a minor plebeian family at ancient Rome. The gens first appears in history towards the close of the Republic, and they did not achieve much importance until the latter half of the second century, when Lucius Septimius Severus obtained the imperial dignity.
The gens Sallustia, occasionally written Salustia, was a plebeian family at ancient Rome. Members of this gens are first mentioned in the time of Cicero, and from that time they attained particular distinction as statesmen and writers. The most illustrious of the family was the historian Gaius Sallustius Crispus, who wrote valuable works on the Jugurthine War and the Conspiracy of Catiline, which still exist.
The gens Seia was a minor plebeian family of equestrian rank at ancient Rome. Members of this gens are first mentioned in the time of Cicero, and a few of them held various magistracies under the late Republic and into imperial times.
The Sassanid campaign of Alexander Severus was an episode of the Roman–Sasanian Wars (224-363) that saw the Roman Empire ruled by Emperor Alexander Severus (222-235) confront the dominance of the Sasanids, led by Ardashir I (224-241): the war was fought between 230 and 232, originating from an attempted Sasanian expansion into the eastern Roman provinces, and resolved with a return to the status quo ante.
