On this day in Tudor history, 20th June 1567, a silver casket of eight letters were allegedly found in the possession of James Hepburn, Earl of Bothwell, the third husband of Mary, Queen of Scots.
These letters, which became known as the Casket Letters, were instrumental in bringing down Mary, Queen of Scots.
Let me tell you a bit more about the Casket Letters and why they were "dynamite" for Elizabeth I's advisors.

And on this day in Tudor history, the night of 20th/21st June 1585, in the reign of Queen Elizabeth I, Henry Percy, 8th Earl of Northumberland, died at the Tower of London.
Was his death murder or suicide? And if it was murder, why?
