Bloody Mary was Mary Tudor, Queen of England, and daughter of King Henry the 8th and Catherine of Aragon. All her life, she was a mean brat to her little sister, Elizabeth and her brother Edward VI. She did not like them at all and was very jealous. When Edward VI died, she became Queen Mary of England. She was hated all over for changing the religion in England from Protestant to Roman Catholic. She mass-murdered over 100 Protestant leaders, earning her name as "Bloody Mary".
