What will King Charles III's reign be called, and will there be a coronation?

London — The reign of Great Britain's new monarch, King Charles III, began immediately when his mother, Queen Elizabeth II, died on September 8. But even a royal transition planned meticulously over the course of Elizabeth's record 70-year reign has left some big questions unanswered.

Many have started to wonder aloud, for instance, what the next period of British history might actually be called.

The queen's death last Thursday marked the end of the second Elizabethan era.
