The native form of this real name is ecsedi Báthory Erzsébet.
Countess Elizabeth Báthory de Ecsed (Báthory Erzsébet in hungarian, Alžbeta Bátoriová in Slovak: 7 August 1560 – 21 August 1614) was a countess from the renowned Báthory family of Hungarian nobility. She is considered the most prolific female serial killer in history and possibly the most prolific of any gender.She and four collaborators were accused of torturing and killing hundreds of girls, with one witness attributing to them over 650 victims, though the number for which they were convicted was 80. She was addicted to beauty and want to stay young and beautiful for the rest of her life. The idea of torturing and killing girls started when she slapped one of her servants for her negligence and blood started bleed from the girls nose. When she saw the incident she was actually amazed that somehow she saw the girls face started to sparkle and it looks beautiful in her eyes. Then, she ordered her servant to tied up the girl and quickly asked them to take her to the bath tub and then cut the girls hand in order to let blood flow into it. After that she takes a bath of the girls blood.
She started to kill any other girls who work for her in the castle for his addiction of beauty but then she started to felt that normal girls don't have the affection anymore and this has led her to kill those aristocratic class of girls as her victim. Her obsession towards beauty is neither crazy and scary but she doesn't think of that way that she always persuade those aristocratic girls to come to her castle so that she may obtain blood for her affection. Many had tried to convince that the countess was a serial killer but neither succeed as she is a countess and people don't have the courage to acuse her.
Elizabeth herself was neither tried nor convicted. In 1610, however, she was imprisoned in the Csejte Castle, now in Slovakia and known as Čachtice, where she remained bricked in a set of rooms until her death four years later.
Later writings about the case have led to legendary accounts of the Countess bathing in the blood of virgins in order to retain her youth and subsequently also to comparisons with Vlad III the Impaler of Wallachia, on whom the fictional Count Dracula is partly based, and to modern nicknames of the Blood Countess and Countess Dracula.
She is someone scary isn't it? But they do have a video of her story, I never watched one but then I wanted to, just that I haven't found one yet.
