Richard III of England
Richard was part of the House of York during the Wars of the Roses. He was the younger brother of King Edward IV. When Edward IV died, his 12-year-old son became King Edward V. Richard was given the role of "Protector", meaning he would run the country until Edward V became an adult. But Richard III took the throne for himself. Soon after, Edward V and his younger brother disappeared while living in the Tower of London.
