Elizabeth Bathory held a very lofty position as a noblewoman hailing from the Kingdom of Hungary. She has gone down in history as one of the most formidable female serial killers of all time. In fact, the Guinness Book of World Records even recognized her for her grim legacy.

Eventually, Bathory’s story warped in places to the point that she seemed like a product of legend. One enduring rumor is that she bathed in her victim’s blood. Whether the rumors hold true or not, it is certain that Bathory’s penchant for torture was very real and many died at her hand.
