Marcus Aurelius

Marcus Aurelius Antoninus was Roman emperor from 161 to 180. A Stoic philosopher, he was a member of the Nerva–Antonine dynasty, the last of the Five Good Emperors and the last emperor of the Pax Romana, a golden age of relative peace, calm, and stability for the Roman Empire lasting from 27 BC to 180 AD. Marcus Aurelius was the son of the praetor Marcus Annius Verus and his wife Domitia Calvilla. He was related through marriage to the emperors Trajan and Hadrian. He served as Roman consul in 140, 145, and 161.

Marcus Aurelius acceded to the throne in 161 alongside his adoptive brother, who took the regnal name Lucius Aurelius Verus. On his deathbed in the spring of 161, Emperor Antoninus Pius had spoken of nothing but his hatred of Vologases IV of Parthia, who made his move in late summer 161. The Parthian War of Lucius Verus was fought between the Roman and Parthian Empires over Armenia and Upper Mesopotamia. It concluded in 166 after the Romans sacked Ctesiphon, the Parthian capital.

Marcus Aurelius reduced the silver purity of the denarius to about 75% or less, a decrease from 83% to 84%. The Antonine Plague broke out in 165 and devastated the Roman Empire, causing the deaths of millions. Lucius Verus may have died from the plague in 169. Marcus Aurelius died in 180 and he was succeeded by his son Commodus. Marcus Aurelius’ reign is regarded as the end of the Pax Romana. (Roman Peace)

Commodus as Hercules

The preceding four emperors (Nerva, Trajan, Hadrian and Antoninus Pius) each adopted their successor, thus choosing a worthy candidate. Marcus Aurelius’ biological son Commodus marked, according to a famous quote by the Roman historian Cassius Dio, the descent "from a kingdom of gold to one of iron and rust". Commodus embarked on a career of bizarre, erratic behavior and monstrous cruelty. He enjoyed executing his enemies and perceived enemies personally.

It was the beginning of the end of Rome. In the words of a senator, Commodus himself was a curse worse than any plague.
