With rare exceptions, the earliest institution of cult to emperors succeeded in providing a common focus of identity for Empire. It celebrated the charisma of Roman Imperial power and the meaning of Empire according to local interpretations of "romanitas", firstly an agency of transformation, then of stability. Cult to Imperial deities was associated with commonplace public ceremonies, celebrations of extraordinary splendour and unnumbered acts of private and personal devotion. The political usefulness of such an institution implies neither mechanical insincerity nor lack of questioning about its meaning and propriety: an Empire-wide, unifying cult would necessarily be open to a multitude of personal interpretations but its significance to ordinary Romans is almost entirely lost in the critical interpretations of a small number of philosophically literate, skeptical or antagonistic Romans and Greeks, whether Christian or Hellene. The decline of prosperity, security and unity of Empire was clearly accompanied by loss of faith in Rome's traditional gods and – at least in the West – in Roman emperors. For some Romans, this was caused by the neglect of traditional religious practices. For others – equally Roman – breakdown of empire was God's judgment on faithless or heretical Christians and hardened pagans alike.
