Following the death of the Queen on Thursday, the Duke and Duchess of Sussex’s children are now entitled to their royal titles. Their son, Archie Mountbatten-Windsor, is now technically a prince while his younger sister, Lilibet “Lili” Mountbatten-Windsor, is entitled to be a princess.
The new titles come courtesy of protocols established by King George V in 1917. Those rules state that any child or grandchild of a sovereign automatically has the right to the title HRH and prince or princess.
Both three-year-old Archie and 15-month-old Lili were the great-grandchild of a sovereign at the time of their births, hence the lack of titles to this point. The Queen’s death on September 8 led to the accession of the Prince of Wales, to King Charles III, who is Archie and Lili’s grandfather.
