Some extra relevant information:
The Nerva-Antonine Dynasty of ancient Rome is renowned for its series of capable and wise emperors who brought stability, prosperity, and a golden age to the Roman Empire. This period, also known as the Five Good Emperors, spanned from 96 AD to 180 AD. The five emperors during this dynasty were Nerva, Trajan, Hadrian, Antoninus Pius, and Marcus Aurelius.
However, the one emperor who is not traditionally considered one of the Five Good Emperors is Commodus. Commodus succeeded his father, Marcus Aurelius, and became the last emperor of the Nerva-Antonine Dynasty. Unfortunately, Commodus deviated from the virtuous and competent reigns of his predecessors, leading to the decline of the dynasty.
Commodus is often characterized as a tyrant due to his erratic behavior, extravagant lifestyle, and lack of interest in governing. He was known for his love of gladiatorial combat, often competing in the arena himself. Commodus indulged in personal pleasure and neglected the affairs of the state, leading to corruption and mismanagement.
His rule marked the end of the stability and prosperity that had been established by the Five Good Emperors. Commodus’ reign was marked by political instability, economic decline, and military difficulties. Upon his death in 192 AD, the Roman Empire plunged into a period known as the Year of the Five Emperors, which witnessed a series of civil wars and power struggles.
While Commodus may have been part of the Nerva-Antonine Dynasty, he is not regarded as one of the Five Good Emperors due to his unfavorable reign and the regression of the empire during his rule. The Five Good Emperors of the Nerva-Antonine Dynasty are celebrated for their contributions to Rome’s stability, expansion, and thriving culture, with Commodus as an unfortunate exception to this otherwise legendary group.
