With The Queen's death, Archie and Lilibet are now prince and princess

The death of Queen Elizabeth II on Thursday set off a shift in the line of succession to the throne, starting with her oldest son, now King Charles III. Thanks to a rule created by King George in 1917, The Queen’s death also means Archie and Lilibet Mountbatten-Windsor, the children of Prince Harry and Meghan, the Duchess of Sussex, now technically hold the titles and ranks of prince and princess.
