Thomas Howard, 3rd Duke of Norfolk, KG (1473 25 August 1554) was a prominent Tudor politician. He was uncle to Anne Boleyn and Catherine Howard, two wives of King Henry VIII, and played a major role in the machinations behind these relationships. After falling from favour, he was stripped of his dukedom and imprisoned in the Tower of London, but was released on the accession of Queen Mary I. He aided Mary in securing her throne, setting the stage for alienation between his Catholic family and the Protestant royal line that would be continued by his great-niece, Queen Elizabeth I.
