How many protestants did queen Mary kill?

Bloody Mary was from the house of Stewart she was a devout Catholic and queen. She was determined to ride the world of the unholy protdesents She would sent them to the Tower of London to be torchered then burnt at the stake. No one knows exactly why she did this but like I said she was ready to ride the world of them and almost succeeded. This is what started the Protestant Revolution. Her real name was Mary Tudor.
