On this day in 1554, Lady Jane Grey was executed on the orders of Queen Mary.  She  had previously been proclaimed Queen on July 10^th, 1553, only to be usurped by Mary nine days later on July 19^th, and   tried and convicted of high treason on November 13^th.  This was despite the previous King, Edward VI, having in his will  nominated her  as his preferred successor to the throne (she being a fellow  Protestant; Mary,  a Catholic).

Lady Jane’s father, Henry Grey, was  executed a matter of a few days later, on February 23rd, for his role in “Wyatt’s Rebellion”.
