The Roman imperial cult transformed emperors into gods, blending politics and religion. Starting with Julius Caesar, this practice grew under Augustus, with rituals like apotheosis and consecratio solidifying an emperor's divine status after death.

Emperor worship unified the empire and legitimized imperial rule. Living emperors were honored through their genius and numen, while provincial cults spread the practice empire-wide. This system integrated local traditions and became a loyalty test for citizens.
