paragraph_text: Nerva–Antonine dynasty
  
  Following Domitian's murder, the Senate rapidly appointed Nerva as Emperor. Nerva had noble ancestry, and he had served as an advisor to Nero and the Flavians. His rule restored many of the traditional liberties of Rome's upper classes, which Domitian had over-ridden. The Nerva–Antonine dynasty from 96 AD to 192 AD included the "five good emperors" Nerva, Trajan, Hadrian, Antoninus Pius and Marcus Aurelius. Trajan, Hadrian, Antoninus Pius and Marcus Aurelius were part of Italic families settled in Roman colonies outside of Italy: the families of Trajan and Hadrian had settled in Italica (Hispania Baetica), that of Antoninus Pius in Colonia Agusta Nemausensis (Gallia Narbonensis), and that of Marcus Aurelius in Colonia Claritas Iulia Ucubi (Hispania Baetica). The Nerva-Antonine dynasty came to an end with Commodus, son of Marcus Aurelius.
  
  Nerva abdicated and died in 98 AD, and was succeeded by the general Trajan. Trajan is credited with the restoration of traditional privileges and rights of commoner and senatorial classes, which later Roman historians claim to have been eroded during Domitian's autocracy. Trajan fought three Dacian wars, winning territories roughly equivalent to modern-day Romania and Moldova. He undertook an ambitious public building program in Rome, including Trajan's Forum, Trajan's Market and Trajan's Column, with the architect Apollodorus of Damascus. He remodelled the Pantheon and extended the Circus Maximus. When Parthia appointed a king for Armenia without consulting Rome, Trajan declared war on Parthia and deposed the king of Armenia. In 115 he took the Northern Mesopotamian cities of Nisibis and Batnae, organised a province of Mesopotamia (116), and issued coins that claimed Armenia and Mesopotamia were under the authority of the Roman people. In that same year, he captured Seleucia and the Parthian capital Ctesiphon (near modern Baghdad). After defeating a Parthian revolt and a Jewish revolt, he withdrew due to health issues, and in 117, he died of edema.
  
  Trajan's successor Hadrian withdrew all the troops stationed in Parthia, Armenia and Mesopotamia (modern-day Iraq), abandoning Trajan's conquests. Hadrian's army crushed a revolt in Mauretania and the Bar Kokhba revolt in Judea. This was the last large-scale Jewish revolt against the Romans, and was suppressed with massive repercussions in Judea. Hundreds of thousands of Jews were killed. Hadrian renamed the province of Judea " Provincia Syria Palaestina ", after one of Judea's most hated enemies. He constructed fortifications and walls, like the celebrated Hadrian's Wall which separated Roman Britannia and the tribes of modern-day Scotland. Hadrian promoted culture, especially the Greek. He forbade torture and humanised the laws. His many building projects included aqueducts, baths, libraries and theatres; additionally, he travelled nearly every province in the Empire to review military and infrastructural conditions. Following Hadrian's death in 138 AD, his successor Antoninus Pius built temples, theatres, and mausoleums, promoted the arts and sciences, and bestowed honours and financial rewards upon the teachers of rhetoric and philosophy. On becoming emperor, Antoninus made few initial changes, leaving intact as far as possible the arrangements instituted by his predecessor. Antoninus expanded Roman Britannia by invading what is now southern Scotland and building the Antonine Wall. He also continued Hadrian's policy of humanising the laws. He died in 161 AD.
  
  Marcus Aurelius, known as the Philosopher, was the last of the Five Good Emperors. He was a stoic philosopher and wrote the Meditations. He defeated barbarian tribes in the Marcomannic Wars as well as the Parthian Empire. His co-emperor, Lucius Verus, died in 169 AD, probably from the Antonine Plague, a pandemic that killed nearly five million people through the Empire in 165–180 AD.
  
  From Nerva to Marcus Aurelius, the empire achieved an unprecedented status. The powerful influence of laws and manners had gradually cemented the union of the provinces. All the citizens enjoyed and abused the advantages of wealth. The image of a free constitution was preserved with decent reverence. The Roman senate appeared to possess the sovereign authority, and devolved on the emperors all the executive powers of government. Gibbon declared the rule of these "Five Good Emperors" the golden era of the Empire. During this time, Rome reached its greatest territorial extent.
  
  Commodus, son of Marcus Aurelius, became emperor after his father's death. He is not counted as one of the Five Good Emperors, due to his direct kinship with the latter emperor; in addition, he was militarily passive. Cassius Dio identifies his reign as the beginning of Roman decadence: "(Rome has transformed) from a kingdom of gold to one of iron and rust."
