Nerva: Marcus Cocceius Nerva was born at Narnia in Umbria in 32 CE. He was consul with Vespasian in 71 and with Domitian in 90. After the assassination of Domitian, he was declared emperor by the Roman people and the soldiers, and his administration restored tranquility to the troubled state. He stopped proceedings against those accused of treason and permitted many exiles to return. Though he was virtuous and humane, he did not possess the necessary vigor for checking the many abuses that existed. He adopted as his son and successor Marcus Ulpius Trajan, who was then at the head of the army in Germany. He died suddenly on the 27th of January, 98 CE (Hazzard).

Those who conspired to kill Domitian and elevate Nerva included his wife, Domiltilla, his chamberlain, Parthenias, and the new Praetorian prefects, Petronius Secundus and Norbanus. The actual assassin was Stephanus, his niece Domitilla's steward, aided by Parthenius' servants (Suetonius, Domitian 16-17; Dio Cassius 67.15-18; Aurelius Victor, Epitome 12.2). (Bird)
