Charlemagne's coronation was performed by a pope.
Charlemagne ( SHAR-l-mayn, -MAYN, French: [alma]) or Charles the Great (Latin: Carolus Magnus; 2 April 747  28 January 814), a member of the Carolingian dynasty, was King of the Franks from 768, King of the Lombards from 774, and the Emperor of the Romans from 800
 The Papacy retains the option of a coronation, but no pope has used it since 1963 to 2023 after Pope John Paul I opted for a papal inauguration in 1978
