Enthronement

"An enthronement is a ceremony of inauguration, involving a person—usually a monarch or religious leader—being formally seated for the first time upon their throne. Enthronements may also feature as part of a larger coronation rite.

In a general sense, an enthronement may also refer to a ceremony marking a monarch´s accession, generally distinguished from a coronation as no crown or other regalia is physically bestowed upon the one being enthroned, although regalia may be present at the ceremony.

Enthronements occur in both church and state settings, since the throne is seen as a symbol of authority, both secular and spiritual." - (en.wikipedia.org 09.11.2021)
