On 18 September, A.D. 96, Domitian was assassinated and was succeeded on the very same day by M. Cocceius Nerva, a senator and one of his amici. The sources are unanimous in stressing that this was a palace plot, yet it is difficult to determine the level of culpability among the various potential conspirators. In many ways, Domitian is still a mystery - a lazy and licentious ruler by some accounts, an ambitious administrator and keeper of traditional Roman religion by others. As many of his economic, provincial, and military policies reveal, he was efficient and practical in much that he undertook, yet he also did nothing to hide the harsher despotic realities of his rule. This fact, combined with his solitary personality and frequent absences from Rome, guaranteed a harsh portrayal of his rule. The ultimate truths of his reign remain difficult to know.
