Is there a difference between “Your Grace” and “Your Majesty” in terms of deference and respect? Why is pre-conquest Westeros so uniform when it comes to royal styles?
Yes, and it has to do with fashions of royla address. According to Francois Velde of heraldica.org, “Your Highness” was the most common style across Europe from the 12th through 15th centuries CE. When Charles V became Holy Roman Emperor in 1519, he decided that he was too special to be a mere “Highness” – he did after all rule an empire that spanned from Asia to the Americas to eastern Europe – and instructed his court that he be described as “Majesty.”
Francois I of France, who would spend his entire reign fighting Charles V, wasn’t going to take this lying down and so insisted on also being referred to as “Majesty,” which led to a good deal of linguistic one-upmanship where Charles insisted on being called “Imperial Majesty” to Francois’ mere “Royal Majesty” and then Francois retaliated by using “Most Christian Majesty,” and so on. Henry VIII of England, who would be out-ego’d by no man, also began using “Majesty.” Just to confuse everyone, though, the English court continued to call him “Grace” and “Highness” as well as “Majesty” in legal documents, until the reign of James I, where it was regularized that the King is a “Majesty,” and Dukes and Archbishops are “Graces.”
I think Francis was the one having issues. Charles upgrading his title wasn’t unreasonable considering how much land he ruled – all that universal monarch business – while Francis (who lost the imperial election) did the same despite not actually ruling any extra territory.
@racefortheironthrone, were there political advantages in the title upgrade for Francis and Henry, or was it purely an ego thing? I could see either being the case.
Given that it’s nothing but symbolic politics from the start, it was really egos all around. I’d add that Charles’ upgrading and his land didn’t end up helping him that much in the long run – hence his decision to divide the empire on his retirement, due to his belief that the concentration of so much land in one person had led to the Hapsburgs getting ganged up on by everyone around them…
