The Senate chose the elderly, childless and apparently reluctant Nerva as emperor. Nerva had long-standing family and consular connections with the Julio-Claudian and Flavian families, but proved a dangerously mild and indecisive "princeps": he was persuaded to abdicate in favour of Trajan. Pliny the Younger's panegyric of 100 AD claims the visible restoration of senatorial authority and dignity throughout the empire under Trajan, but while he praises the emperor's modesty, Pliny does not disguise the precarious nature of this autocratic gift. Under Trajan's very capable civil and military leadership, the office of emperor was increasingly interpreted as an earthly viceregency of the divine order. He would prove an enduring model for Roman imperial virtues.
