On May 6th, King Charles will become the oldest person to ascend the throne of the United Kingdom. He is a bit of an odd duck to be the king, Rebecca Mead thinks. Charles has “long made clear that he considers his birthright a burden,” she writes. In fact, many things are a burden: during the ceremonies following the death of Queen Elizabeth, the new king “got into not one but two altercations with malfunctioning pens. . . . As his biographer Catherine Mayer puts it, ‘The world is against him—even inanimate objects are against him. That is absolutely central to his personality.’ ” Mead—a subject of the king, as well as a staff writer—talks with David Remnick about Charles III’s coronation, the problem of Harry and Meghan, and the future of the British monarchy itself.
