Septimius Severus
On the 11th of April in 145, Lucius Septimius Severus drew his first breath within the walls of Leptis Magna. This city sat in the Roman province of Africa, now known as Libya. He emerged from a wealthy family holding equestrian rank. His father Publius Septimius Geta hailed from Punic stock while his mother Fulvia Pia descended from Italian patricians of the gens Fulvia. Cassius Dio later described him as Libyan by race. This background made him the first emperor born outside Italy to a non-Italian provincial family.
His early education combined native Punic speech with Latin and Greek lessons. He spoke the latter languages with a noticeable accent. At age seventeen he delivered his first public speech before an audience. The boy craved more learning than his circumstances allowed. A plague struck Rome in 166 forcing his career into pause. He returned home to Leptis Magna where the air was healthier for recovery.
Severus eventually resumed his path toward public office around 162. Emperor Marcus Aurelius granted him entry into the senatorial ranks following advice from a relative. He served as State Attorney and likely oversaw road maintenance near the capital. The Antonine Plague had thinned the Senate ranks creating opportunities for capable men like him. By December 5th of 169 he took office as quaestor and entered the Senate officially.
The year 193 marked a violent turning point when Emperor Pertinax died at the hands of the Praetorian Guard. Didius Julianus bought the throne through an auction but the Senate condemned him to death. Severus heard news of the chaos while commanding legions in Pannonia Superior. On April 9th, legion XIV Gemina acclaimed him emperor at Carnuntum. Nearby units including X Gemina soon followed suit.
He marched on Italy with an army loyal to him alone. Upon reaching Rome he executed those responsible for Pertinax's murder. He dismissed the entire Praetorian Guard and filled their ranks with veterans from his own Danubian legions. This move secured his power base before facing external threats. Pescennius Niger claimed the throne in Syria while Clodius Albinus held Britannia.
Severus defeated Niger at the Battle of Issus in 194. He then turned north to face Albinus who had been declared emperor by his troops. The clash occurred on February 19th of 197 at Lugdunum in Gaul. An army of roughly 75,000 men fought there. Severus killed Albinus and took full control of the empire. He subsequently executed twenty-nine senators who had supported his rival despite previous promises.
In early 197 Severus sailed eastward from Brundisium to Cilicia. He crossed the Euphrates river to gather his forces against the Parthian Empire. King Abgar IX of Osroene provided archers and hostages to assist the Roman expedition. Khosrov I of Armenia sent money and gifts as well. His general Julius Laetus prevented Nisibis from falling into enemy hands earlier.
The following year he launched a major campaign against Parthia. His legions sacked the royal city of Ctesiphon in retaliation for support given to Pescennius Niger. He annexed northern Mesopotamia to expand the eastern frontier all the way to the Tigris River. This victory earned him the title Parthicus following Trajan's example. However he failed to capture the fortress of Hatra after two long sieges.
Severus also strengthened defenses along the Arabian Desert. He built new fortifications stretching from Basie to Dumatha within Arabia Petraea. These actions secured the southern flank while expanding Roman influence deep into the Near East. The campaigns demonstrated both military prowess and strategic ambition across vast distances.
By 208 Severus traveled north to Britain with an army exceeding forty thousand men. He intended to conquer Caledonia beyond Hadrian's Wall. Archaeological evidence shows camps large enough to house such numbers existed during his stay. He rebuilt abandoned forts like Carpow along the east coast. A strong naval force supported these operations.
Cassius Dio recorded that by 210 significant gains had been made despite guerrilla tactics. The Caledonians sued for peace on condition they surrender control of the Central Lowlands. Later that year they revolted alongside the Maeatae tribe due to desperation over supplies. Severus prepared for a prolonged campaign intending total destruction of his enemies.
He told his soldiers no one should escape not even a male child in the womb. His ambitions ended abruptly when he fell ill with an infectious disease. He withdrew to Eboracum where he died on February 4th of 211. His body was cremated there before being moved to Rome. The frontier eventually retreated south back to Hadrian's Wall permanently.
Upon taking power in 193 Severus discharged the old Praetorian Guard entirely. Their ceremonial armor was stripped and they were banned from coming within seven hundred paces of Rome under penalty of death. He replaced them with ten new cohorts drawn from Danubian veterans loyal to him personally.
Around 197 he increased the number of legions from thirty to thirty-three. Three new units named I, II and III Parthica joined the ranks. Legio II Parthica garrisoned Albanum just eight miles from Rome. This stationing marked the first time imperial troops operated directly inside Italy itself.
Severus raised annual wages for legionaries from three hundred denarii to four hundred. Each soldier received a donative payment of one thousand sesterces upon promotion. These financial incentives secured loyalty but placed heavy burdens on state finances. The policy created a military monarchy that prioritized army interests over senatorial authority.
Trajan's earlier policy allowed Christians punishment only if they refused worship of the emperor. Under Severus persecution remained inconsistent and local rather than empire-wide. Some sources suggest he issued an edict punishing conversion to Judaism or Christianity. Early church historian Eusebius described him as a persecutor in later accounts.
Christian apologist Tertullian claimed otherwise stating Severus was well disposed toward believers. He employed a Christian physician and intervened to save high-born Christians known to him from mob violence. Many deaths attributed to his reign likely resulted from local actions by provincial governors instead of central decrees.
The martyrs of Madauros Charalambos and Perpetua and Felicity died during this period. Their stories reflect regional tensions rather than systematic imperial campaigns against faith communities. Historical records remain divided on whether these events stemmed from official policy or local initiative.
To fund his enlarged military Severus debased Roman currency significantly. Upon accession he lowered silver purity of the denarius from 81.5 percent to 78.5 percent while increasing weight slightly. The following year he reduced purity again to 64.5 percent dropping weight to 1.98 grams.
By 196 the silver content fell further to 54 percent with weight at 1.82 grams. This represented the largest debasement since Nero's reign compromising long-term economic stability. Rising military expenditures forced repeated cuts to coin value despite initial attempts to maintain quality.
Civilian populations bore heavier taxes and services to support the expanded army. Cassius Dio and Herodianus criticized these policies for creating unsustainable financial burdens. Problems caused by increased spending plagued all subsequent emperors who inherited the treasury.
Severus established the Severan dynasty through his sons Caracalla and Geta. He proclaimed Caracalla Augustus in 198 and Geta co-emperor in 209. His wife Julia Domna advised them after his death on February 4th of 211. This line became the final dynasty before the Crisis of the Third Century began.
Edward Gibbon later condemned him as a principal agent in Rome's decline. He argued posterity experienced fatal effects from Severus's maxims and example. The empire reached over four million square kilometers under his rule according to modern scholars. David L. Kennedy and others assert this marked its greatest physical extent.
His buildings included triumphal arches in Rome and Leptis Magna. The Septizodium stood among other structures enriching his native city. Yet historians debate whether military expansion secured stability or accelerated collapse. Cassius Dio recorded his dying advice: be harmonious with your brothers but enrich soldiers above all else.
