Hundreds gathered around the Mercat Cross in the capital for the ceremony which was attended by Scottish councilors and preachers and persecutors.
As Lord Lyon, the King of Arms concluded his proclamation by saying “God save the King,” there were loud cheers.
However, most of the crowd joined the official, shouting “God save the King” in return.
The national anthem was then sung by the crowd, after which a group of people could be heard calling for democracy.
Scottish campaign group Our Republic had earlier “encouraged” those who objected to the proclamations to “make it clear”.

On Twitter, the groups said they were initially arrested on suspicion of “breaching the peace” but were eventually released without charge.
The Scottish Community & Activist Legal Project later accused the police of being “heavy-handed”.
An anti-monarchy protester holding a sign reading, “F*** imperialism, abolish the monarchy” was arrested.
The police appeared and then took her away moments later and the crowd began to applaud.
Others, however, questioned the decision.
A man shouted, “Let her go! It’s freedom of speech!”. while others shouted: “Have some respect.”
A Police Scotland spokesman said: “A 22-year-old woman was arrested outside St. Giles in Edinburgh on Sunday the 11th of September 2022 in relation to a breach of the peace.’
