Marcus Didius Severus Julianus (133 or 137–193) was briefly
Roman Emperor from
28 March 193 to
1 June 193. He ascended the throne after buying it from the
Praetorian Guard, who had assassinated his predecessor
Pertinax. This led to the Roman Civil War of 193–197. Julianus was ousted and sentenced to death by his successor,
Septimius Severus.
Early life
Julianus was born to
Quintus Petronius Didius Severus and
Aemilia Clara. Julianus's father came from a prominent family in
Milan and his mother was an African woman, of Roman descent. Clara came from a family of consular rank. His brothers were Didius Proculus and Didius Nummius Albinus. His date of birth is given as
January 30 133 by
Cassius Dio and
February 2 137 by the
Historia Augusta. Didius Julianus was raised by
Domitia Lucilla, mother of Roman Emperor
Marcus Aurelius. With Domitia's help, he was appointed at a very early age to the
vigintivirate, the first step towards public distinction. He married a Roman woman called
Manlia Scantilla and about 153, Scantilla bore him a daughter and only child
Didia Clara.
Career
He held in succession the offices of
Quaestor, and then
Aedile, and then around 162 Julianus was named as
Praetor. He was nominated to the command of the
Legio XXII Primigenia in
Mogontiacum (now
Mainz). Starting in 170 he became praefectus of
Gallia Belgica for five years. As reward for his skill and gallantry in repressing an insurrection among the
Chauci, a tribe dwelling on the
Elbe, he was raised to the consulship in 175, along with
Pertinax. He further distinguished himself in a campaign against the
Chatti, ruled
Dalmatia and
Germania Inferior, and then was made prefect charged with distributing money to the poor of
Italy. About this time he was charged with having conspired against the life of
Commodus, but had the good fortune to be acquitted, and to witness the punishment of his accuser. He also governed
Bithynia, and succeeded Pertinax as the
proconsul of
Africa.
Rise to power
After the murder of Pertinax (28 March 193), the Praetorian assassins announced that the throne was to be sold to the man who would pay the highest price.
Titus Flavius Sulpicianus,
prefect of the city, father-in-law of the murdered emperor, being at that moment in the camp to which he had been sent to calm the troops, began making offers, when Julianus, having been roused from a banquet by his wife and daughter, arrived in all haste, and being unable to gain admission, stood before the gate, and with a loud voice competed for the prize. As the bidding went on, the soldiers reported to each of the two competitors, the one within the fortifications, the other outside the rampart, the sum offered by his rival. Eventually Sulpicianus promised 20,000
sesterces to every soldier, and Julianus fearing that Sulpicianus would gain the throne, immediately offered 25,000. The guards immediately closed with the offer of Julianus, threw open the gates, saluted him by the name of Commodus, and proclaimed him emperor. Threatened by the military, the
Senate declared him emperor. His wife and his daughter both received the title Augusta.
Reign
After the initial confusion had subsided, the population did not tamely submit to the dishonour brought upon Rome. Whenever Julianus appeared in public he was saluted with groans, imprecations, and shouts of "robber and parricide. The mob tried to obstruct his progress to the
Capitol, and even threw stones.
When news of the public anger reached the generals in different parts of the empire, Pescennius Niger in Syria, Septimius Severus in Pannonia, and Clodius Albinus in Britain, each having three legions under his command, refused to recognize the authority of Julianus. Julianus declared Severus a public enemy because he was the nearest and therefore most dangerous foe. Deputies were sent from the Senate to persuade the soldiers to abandon him; a new general was nominated to supersede him, and a centurion dispatched to take his life. The Praetorian Guard, long strangers to active military operations, were marched into the Campus Martius, regularly drilled, and trained in the construction of fortifications and field works. Severus, however, having secured the support of Albinus by declaring him Caesar, progressed towards the city, made himself master of the fleet at Ravenna, defeated Tullius Crispinus, the Praetorian Prefect, who had been sent to halt his progress, and gained over to his cause the ambassadors sent to seduce his troops.
The Praetorian Guard, lacking discipline, and sunk in debauchery and sloth, were incapable of offering any effectual resistance. Matters being desperate, Julianus now attempted negotiation, and offered to share the empire with his rival. But Severus ignored these overtures, and still pressed forwards, all Italy declaring for him as he advanced. At last the Praetorians, having received assurances that they would suffer no punishment, provided they would surrender the actual murderers of Pertinax, seized the ringleaders of the conspiracy, and reported what they had done to Silius Messala, the consul, by whom the Senate was summoned and informed of the proceedings. The Senate passed a motion proclaiming Severus emperor, awarding divine honours to Pertinax, and sentencing Julianus to death. Julianus was deserted by all except one of the prefects and his son-in-law, Repentinus. Julianus was killed in the palace by a soldier in the third month of his reign (1 June 193). Severus dismissed the Praetorian Guard and executed the soldiers who had killed Pertinax. According to Cassius Dio, who lived in Rome during the period, Julianus's last words were "But what evil have I done? Whom have I killed? His body was given to his wife and daughter, who buried it in his great-grandfather's tomb, by the fifth milestone on the Via Labicana.
