Damnatio memoriae

The balance of a reign was made up after the death of an emperor, when the Senate convened and decided whether the ruler had become a god and deserved a public cult (a practice that was known from the Hellenistic world and was introduced in Rome after the death of Julius Caesar). When there was not doubt about the succession, the apotheosis was self-evident. When Hadrian died in 138 and the Senate hesitated, his successor Antoninus Pius made sure that the dead man was recognized as a god.

On other occasions, however, debate was more serious. In 54, Nero had some difficulty to obtain the deification of his stepfather Claudius. After a rule that was considered to have been a bad one, the ruler was officially condemned, and his name was erased from inscriptions (abolitio nominis). His portraits were sometimes destroyed and even mints could be restamped. Several rulers were not officially condemned, but received this treatment anyhow, and other emperors were rehabilitated after an initial damnatio memoriae.

The custom is not recorded in the Palmyrene Empire and the Gallic Empire. Apotheosis and damnatio memoriae are still known from the end of the fourth century and were, therefore, considered to be religious practices no longer; otherwise, the practice would have been abandoned after Constantine's conversion to Christianity.
