Countess Elizabeth Báthory was a Hungarian noblewoman and one of the most wealthy and powerful aristocrats in eastern Europe during the late 16th and early 17th centuries. Together with her husband Ferenc Nádasdy, a military hero known as the Black Knight of Hungary, Báthory held numerous estates, lands, and villages. She also currently holds the Guinness World Record for being the most prolific female serial killer and most prolific murderer of the western world. Báthory had been accused in the testimonies of over 300 witnesses and survivors of some of the most horrific tortures and murders imaginable before she was arrested, even by medieval standards. Her victims were her maidservants and lesser noble protégés, all girls, with some as young as ten years old. Years after her death, a legend had formed that Báthory had even routinely bathed in and possibly drank the blood of her virginal victims, believing that the pureblood had retained her beauty.
