March 18, 978 - Edward, King of England was murdered at Corfe Castle. It is thought his stepmother Aelfryth, mother of Ethelred the Unready, ordered the murder because she was eager to see her son crowned. She shouldn't have been so eager...Ethelred was a horrible king.
March 18, 1496 - Princess Mary Tudor was born to Henry VII and Elizabeth of York. She would go on to be Queen of France (for about two months) and then marry her brother's close friend Charles Brandon, Duke of Suffolk. Her unfortunate granddaughter, Jane Grey, was the sad "Nine Days Queen."
