2. Stand When the King Stands

It’s customary for everyone to rise when the monarch stands up, enters, or exits a room. The reason hasn’t been formally explained, but many see it as a gesture of respect for the sovereign.

3. Royals Can’t Travel Together in Certain Cases

As Prince George has just turned 12, he now has to travel separately from his father, Prince William. Because William is first in line to the throne and George is second, they must fly separately to protect the succession.

4. A Black Outfit Is Always Required

Members of the royal family must pack at least one black outfit when traveling. The rule exists so they’re prepared to dress in mourning if a royal dies while they’re away.

“This is a rule that has been in place for over seven decades and is closely followed,” royal commentator Richard Fitzwilliams explained.

The rule began after then-Princess Elizabeth was caught without mourning clothes while in Kenya when her father, King George VI, passed away. She remained on the plane upon landing in the UK until black attire was brought to her.

5. How to Properly Greet the King and Queen

If you’re preparing to meet King Charles and Queen Camilla, don’t stress. Buckingham Palace says there are “no obligatory codes of behaviour – just courtesy.”

That said, traditional greetings are encouraged. Men may perform a neck bow, and women may curtsy. If that’s not comfortable, a handshake is perfectly acceptable.

Addressing the royals properly is also key: begin with “Your Majesty,” followed by “Sir” for the King and “Ma’am” for the Queen.
