Robert Dudley, 1st Earl of Leicester (24 June 1532~1533 – 4 September 1588) was the long standing favourite of Elizabeth I of England. Robert Dudley was temporarily imprisoned, along with his father and brothers Guilford, John, Ambrose and Henry Dudley, in the Tower of London, where his stay coincided with the imprisonment of his childhood friend, Lady Elizabeth Tudor, who had been sent there on the orders of her estranged elder sister, Queen Mary I of England. By this time he was already married to Amy Robsart. A document titled "Leycester's Commonwealth", banned in England when published in Europe, proposes an elaborate conspiracy regarding Dudley.
