Though set in the late 15th century, ruling monarchs are given the treatment "Majesty" through the series. No monarch, in Spain or elsewhere, received this treatment before 1517, when it was invented by Charles V upon his election as Holy Roman Emperor (Charles had already been treated as "Royal Highness" as King in Spain and though that he deserved something that ranked above that once he was Emperor; other monarchs adopted the treatment for themselves later).
