Julia Domna in the context of "Severus Alexander"

The denarius (Latin: [deːˈnaːriʊs]; pl.: dēnāriī, Latin: [deːˈnaːriiː]) was the standard Roman silver coin from its introduction in the Second Punic War c. 211 BC to the reign of Gordian III (AD 238–244), when it was gradually replaced by the antoninianus. It continued to be minted in very small quantities, likely for ceremonial purposes, until and through the Tetrarchy (293–313).

The word dēnārius is derived from the Latin dēnī "containing ten", as its value was originally of 10 assēs. The word for "money" descends from it in Italian (denaro), Slovene (denar), Portuguese (dinheiro), and Spanish (dinero). Its name also survives in the dinar currency.

Marcus Aurelius Antoninus (born Lucius Septimius Bassianus, 4 April 188 – 8 April 217), better known by his nickname Caracalla (/ˌkærəˈkælə/; Latin: [karaˈkalːa]), was Roman emperor from 198 to 217 AD, first serving as nominal co-emperor under his father and then ruling alone after 211 AD. He was a member of the Severan dynasty, the elder son of Emperor Septimius Severus and Empress Julia Domna. Severus proclaimed Caracalla co-ruler in 198, doing the same with his other son Geta in 209. The two brothers briefly shared power after their father's death in 211, but Caracalla soon had Geta murdered by the Praetorian Guard and became sole ruler of the Roman Empire. Julia Domna had a significant share in governance, since Caracalla found administration to be mundane. His reign featured domestic instability and external invasions by the Germanic peoples.

Caracalla issued the Antonine Constitution (Latin: Constitutio Antoniniana), also known as the Edict of Caracalla, which granted Roman citizenship to all free men throughout the Roman Empire. The edict gave all the enfranchised men Caracalla's adopted praenomen and nomen: "Marcus Aurelius". Other landmarks of his reign were the construction of the Baths of Caracalla, the second-largest bathing complex in the history of Rome, the introduction of a new Roman currency named the antoninianus, a sort of double denarius, and the massacres he ordered, both in Rome and elsewhere in the empire. In 216, Caracalla began a campaign against the Parthian Empire. He did not see this campaign through to completion due to his assassination by a disaffected soldier in 217. Macrinus succeeded him as emperor three days later.

The Severan dynasty, sometimes called the Septimian dynasty, ruled the Roman Empire between 193 and 235.It was founded by the emperor Septimius Severus (r. 193–211) and Julia Domna, his wife, when Septimius emerged victorious from civil war of 193 - 197, which began with the Year of the Five Emperors.Their two sons, Caracalla (r. 192–217) and Geta (r. 211), ruled briefly after the death of Septimius.In 217 - 218 there was a short interruption of dynasty's control over the empire by reigns of Macrinus (r. 217–218) and his son Diadumenian (r. 218) before Julia Domna's relatives assumed power by raising her two grandnephews, Elagabalus (r. 218–222) and Severus Alexander (r. 222–235), in succession to the imperial office.

The dynasty's women, Julia Domna, the mother of Caracalla and Geta, and her sister, Julia Maesa, the mother of Julia Soaemias and Julia Mamaea, mothers of Elagabalus and Severus Alexander respectively, were all powerful augustae.They were also instrumental in securing imperial positions for their male relatives.

Julia Maesa (7 May before 160 AD – c. 224 AD) 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.

Born in Emesa, Syria (modern day Homs), to an Arab family of priests of the deity Elagabalus, Maesa and her sister Domna were the daughters of Julius Bassianus. Through her sister's marriage, Maesa became sister-in-law to Septimius Severus and aunt of Caracalla and Geta, who all became emperors. She married fellow Syrian Julius Avitus, who was of consular rank. They had two daughters, Soaemias and Mamaea, who became mothers of Elagabalus and Severus Alexander, respectively.

Damnatio memoriae (Classical Latin pronunciation: [damˈnaːti.oː mɛˈmɔri.ae̯]) is a modern Latin phrase meaning "condemnation of memory" or "damnation of memory", indicating that a person is to be excluded from official accounts. There are and have been many routes to damnatio memoriae including the destruction of depictions, the removal of names from inscriptions and documents, and even large-scale rewritings of history.

Indo-Roman trade relations (see also the spice trade and incense road) was trade between the Indian subcontinent and the Roman Empire in Europe and the Mediterranean Sea. Trade through the overland caravan routes via Asia Minor and the Middle East, though at a relative trickle compared to later times, preceded the southern trade route via the Red Sea, which started around the beginning of the Common Era (CE), following the reign of Augustus and his conquest of Egypt in 30 BCE.

The southern route so helped enhance trade between the ancient Roman Empire and the Indian subcontinent, that Roman politicians and historians are on record decrying the loss of silver and gold to buy silk to pamper Roman wives, and the southern route grew to eclipse and then totally supplant the overland trade route. Roman and Greek traders frequented the ancient Tamil country, present day Southern India and Sri Lanka, securing trade with the seafaring Tamil states of the Pandyan, Chola and Chera dynasties and establishing trading settlements which secured trade with the Indian subcontinent by the Greco-Roman world since the time of the Ptolemaic dynasty a few decades before the start of the Common Era and remained long after the fall of the Western Roman Empire.

Julius Bassianus (born in the second half of the 2nd century, died 217) was an Arab high priest of Elagabalus at the Temple of the Sun in Emesa, Syria, where this solar deity was worshipped in a shape of a black stone. The name Elagabalus derives from Ilāh (a Semitic word for "god") and gabal (an Arabic word for "mountain"), resulting in "the God of the Mountain," the Emesene manifestation of the deity. Bassianus was a member of the Royal family of Emesa (modern Homs), which was a part of the Arab aristocracy in this client kingdom of the Roman Empire. The beginning of his priesthood is unknown, but by 187 he was a high priest at Emesa. Bassianus was a son of a Julius and his paternal uncle was Julius Agrippa, who served as a Primipilaris (a former leading Centurion).

Future emperor Lucius Septimius Severus had visited Emesa, based on a promising horoscope that he would find his future wife in Syria. Bassianus introduced Severus to his two daughters. Bassianus' wife is unknown. His elder daughter Julia Maesa was married to a Syrian noble Gaius Julius Avitus Alexianus and they had two daughters: Julia Soaemias Bassiana and Julia Avita Mamaea. His younger daughter Julia Domna was not married. Severus and Domna married not so long after. Domna bore Severus two sons, Lucius Septimius Bassianus (Caracalla, 4 April 188-8 April 217) and Publius Septimius Geta (7 March 189-19 December 211). Caracalla and Geta would become future Roman Emperors and heirs to their father. After Caracalla's death, Julia Maesa's grandson became emperor, Elagabalus. She prevailed upon him to adopt another grandson of her, the son of Julia Avita Mamaea, who took the name Alexander Severus. Eventually the latter became emperor himself.
