Mary I - Queen of England. One of the most ruthless women in history. Known as "Bloody" Mary, she was responsible for the slaughter of thousands as she attempted to return her kingdom to Catholicism following the reforms of her father, Henry VIII. Upon her death, her half sister Elizabeth I aceded the throne and secured Protestantism as the official state religion.
English: Portrait Of Mary Tudor (1516-1558) oil on Canvas. Source http://www.wikigallery.org/ Author (after) Antonio Mor. An odd portrait, somewhat over-emotional, and not contemporaneous. Most certainly a much later copy, with a religious agenda.
