King Charles III: The New Monarchy

At about 8mins, Ken Wharfe calls Queen Elizabeth II "the longest-reigning monarch ever". This is accurate if he means British monarch, but without stating such it is incorrect, as Louis XIV of France, for example, reigned nearly two years longer, and there are other longer-reigning monarchs whose approximate lengths of reigns (year to year) are known to be longer although their exact dates (day to day) aren't verifiable.
