This is something that I've been wondering about for some time now. The Spanish kings don't have a coronation, but a swearing in before the Cortes. I would've thought that of all the crowns in Europe, Spain that is as doggedly Catholic as it is, would have a pageant of the marriage of monarch and state in the form of a coronation.
Castile hasn't had one since 1379, Aragon since 1414, and Navarre since 1479/1555 (depending on whether you count Jeanne d'Albret's coronation as queen of Navarre as a Spanish affair).
Also, with the Bourbons' concern with the Divine Right of Kings etc, or the Habsburgs' imperial connections, one would think that either the high coronation mass of the emperor or the sacré of St. Remy would've made it into Spain. I could see Felipe II or IV being in his element at such a ceremony.
When would be the best time/who would be the best sovereign to restore the coronation ceremony to Spain?
