An imperial cult is a form of state religion in which an emperor or a dynasty of emperors are worshipped as demigods, deities. "Cult" here is used to mean "worship", not in the modern pejorative sense. The cult may be one of personality in the case of a newly arisen Euhemerus figure, or one of national identity or supranational identity in the case of a multi-ethnic state. A divine king is a monarch who is held in a special religious significance by his subjects, and serves as both head of state and a deity or head religious figure. This system of government combines theocracy with an absolute monarchy.

Worship is showing regard with great respect, honor, or devotion. This may be encountered in religious settings. In such instances it may represent divine worship; reverence for a divine being or supernatural power. This activity may have other focuses, such as hero worship. Worship may involve one or more of activities such as veneration, adoration, praise, supplication, devotion, prostration, or submission. An act of worship can be performed as simple prayer or through elaborate ceremony, individually, in an informal or formal group, or by a designated leader. The focus of worship is ultimately honoring the subject in some manner.
