The long Tudor century (1485-1603) lasted 42,947 days and Lady Jane Grey reigned for nine of them.
Jane’s cousin, the sickly boy-king Edward VI, named her heir to keep Protestantism alive. However, she ultimately proved nothing more than a minor inconvenience to his Roman Catholic sister Mary, who benefited from widespread popular acceptance of her own dynastic legitimacy.
To most historians, therefore, Jane is a footnote at best. And while she has received some recent attention from scholars, the shortness of Jane’s reign means that their focus tends to be more on how she has been presented by others.
