Prince Harry’s son, Archie Harrison Mountbatten-Windsor, would have to bow to his cousins, Prince George, Princess Charlotte and Prince Louis, unless one thing happens.

Grant Harrold, a former royal butler, told Express that it is only when Queen Elizabeth II allows Archie to be styled as His Royal Highness would he not be required to bow to his older cousins. But if the Queen or future King Prince Charles do not bestow Archie with a royal title later on in his life, he would have to bow to his cousins.

“The royal baby will not be a prince or a princess unless the Queen allows it. King George V limited titles within the royal family in 1917… Therefore, Prince Harry and Meghan’s firstborn, as a great-grandchild of the Queen, will be seventh in line to the throne and as such will not be styled HRH either,” he said.

Royal expert Marlene Koenig told the publication that a royal highness doesn’t bow or curtsy to another royal highness. This is the reason why Meghan Markle doesn’t curtsy to Kate Middleton, Camilla Parker Bowles, Prince Charles, and Prince William.

But royals who are styled as His Royal Highness or Her Royal Highness need to bow or curtsy to Her Majesty.

Meanwhile, after Prince William and Middleton’s wedding and before they had children, the monarch stepped in to make sure that all of Cambridge children would be HRH.

Her decision followed George V’s declaration, which states, “The grandchildren of the sons of any such Sovereign in the direct male line (save only the eldest living son of the eldest son of the Prince of Wales) shall have and enjoy in all occasions the style and title enjoyed by the children of dukes of these our realms.”

Prince William and Middleton’s eldest son, Prince George, would still be an HRH even if the Queen didn’t intervene. However, Princess Charlotte and Prince Louis wouldn’t have been known as such if not for their great-grandmother.
