Nerva is proclaimed Roman emperor after Domitian is assassinated.

Domitian (; Latin: Domitianus; 24 October 51 18 September 96) was a Roman emperor who reigned from 81 to 96. The son of Vespasian and the younger brother of Titus, his two predecessors on the throne, he was the last member of the Flavian dynasty. Described as "a ruthless but efficient autocrat", his authoritarian style of ruling put him at sharp odds with the Senate, whose powers he drastically curtailed.

Domitian had a minor and largely ceremonial role during the reigns of his father and brother. After the death of his brother, Domitian was declared emperor by the Praetorian Guard. His 15-year reign was the longest since that of Tiberius. As emperor, Domitian strengthened the economy by revaluing the Roman coinage, expanded the border defenses of the empire, and initiated a massive building program to restore the damaged city of Rome. Significant wars were fought in Britain, where his general Agricola attempted to conquer Caledonia (Scotland), and in Dacia, where Domitian was unable to procure a decisive victory against King Decebalus. Domitian's government exhibited strong authoritarian characteristics. Religious, military, and cultural propaganda fostered a cult of personality, and by nominating himself perpetual censor, he sought to control public and private morals.

As a consequence, Domitian was popular with the people and the army, but considered a tyrant by members of the Roman Senate. Domitian's reign came to an end in 96 when he was assassinated by court officials. He was succeeded the same day by his advisor Nerva. After his death, Domitian's memory was condemned to oblivion by the Senate, while senatorial and equestrian authors such as Tacitus, Pliny the Younger, and Suetonius propagated the view of Domitian as a cruel and paranoid tyrant. Modern revisionists instead have characterized Domitian as a ruthless but efficient autocrat whose cultural, economic, and political programs provided the foundation of the peaceful second century.

Nerva (; originally Marcus Cocceius Nerva; 8 November 30 – 27 January 98) was Roman emperor from 96 to 98. Nerva became emperor when aged almost 66, after a lifetime of imperial service under Nero and the rulers of the Flavian dynasty. Under Nero, he was a member of the imperial entourage and played a vital part in exposing the Pisonian conspiracy of 65. Later, as a loyalist to the Flavians, he attained consulships in 71 and 90 during the reigns of Vespasian and Domitian, respectively.

On 18 September 96, Domitian was assassinated in a palace conspiracy involving members of the Praetorian Guard and several of his freedmen. On the same day, Nerva was declared emperor by the Roman Senate. As the new ruler of the Roman Empire, he vowed to restore liberties which had been curtailed during the autocratic government of Domitian.

Nerva's brief reign was marred by financial difficulties and his inability to assert his authority over the Roman army. A revolt by the Praetorian Guard in October 97 essentially forced him to adopt an heir. After some deliberation Nerva adopted Trajan, a young and popular general, as his successor. After barely fifteen months in office, Nerva died of natural causes on 27 January 98. Upon his death he was succeeded and deified by Trajan.

Although much of his life remains obscure, Nerva was considered a wise and moderate emperor by ancient historians. Nerva's greatest success was his ability to ensure a peaceful transition of power after his death by selecting Trajan as his heir, thus founding the Nerva–Antonine dynasty.
