The first Queen of England was Mary I or Mary Tudor. She reigned from 1553 until her death in 1558. Many people were unhappy with her reign because she persecuted Protestants because she wanted to convert England back to Catholicism - called English Reformation -.

Because of her persecution, she was called Bloody Mary, she killed more than 200 people. Her half-sister, Elizabeth I was her successor.

The answer to ur question is  

Mary Tudor she was the first queen of England she died November 17th 1558 and many people were so unhappy about her reign because everytime people look in a mirror and say bloody Mary 3 times she will come and kill you people called her Bloody Mary because of what she did to the people before she died.
