Countess Barito, the most murderous female serial killer in history, has maimed more than 600 people, most of them young women. It is said that she believed that the blood of young girls could keep her young forever, so she killed girls and drank their blood and even bathed them with donated blood... The movie "The Countess" is based on her real experience.

Elisabeth Bartow (7 August 1560 – 21 August 1614) was a countess who was born into a large family in the Kingdom of Hungary. Her family is related to the legendary god of the forest and the witch. According to legend, the Bathori family had more wealth than the Hungarian kings had at that time. Elizabeth not only had a privileged family background, but was also intelligent and beautiful, she was proficient in Latin, German, and Greek at a young age, and was more interested in science and astronomy, and she was also the first beauty in Hungary.
At the age of fifteen she became engaged to Nádasdy Ferenc, and on 8 May 1575, when nadasdy gave his house, Csejte vára, his villa in Cahtis, and the seventeen surrounding townships as a wedding gift.
After marriage, Count Nadasty often left her to go out on expeditions, and the countess often panicked at home. After the death of the 51-year-old count, she immediately threw the vengeful mother-in-law out of the castle. At this time, the 40-year-old Barito began to fear that aging would rob her of her beauty.
One day, a maid accidentally broke her hair while combing Elizabeth's hair, Elizabeth angrily slapped the maid, the maid's blood splashed on her face, she looked at herself in the mirror, suddenly felt that she had become young by the moisture of blood. So she trusted the girl's blood to help her stay young forever. Since then, with the help of wizards, she has ordered her servants to capture or lure girls from nearby villages to torture them, bleeding them to death as animals in slaughterhouses, drinking their blood, and using them to shower.
More than 600 maidens were said to have been killed in just a few days, and word of disappearance and criticism of the nobility began to circulate, and Hungarian officials sent to investigate the fact that on December 30, 1601, the countess's cousin Count Turso led a group of soldiers and cavalry to surround the castle. In 1610 Barito and her four accomplices were charged with abusing and killing women, four accomplices were sentenced to death, and Barito was imprisoned for life. In 1614, The Countess of Barthori was found dead long ago, and she did not move at the food of many meals, so the true date of The Countess of Barthori's death is not known. Her body was originally intended to be buried in the cemetery of Chakhtis, but due to strong opposition from the residents, it was later transferred to the cemetery of the family in NovoBathori, Hungary.
She is known as one of the top ten realistic vampires in the world. Countess Barthori's acts of torture were brutal, including prolonged beatings to death, burning hands, faces, genitals, cutting off hands, biting off the flesh of the body, cold death, starvation, and sexual abuse. And it happened not only in her castle, but also in the house under her husband's name. After her death, the castle where she used to live was abandoned, and no one dared to move in again. The castle later became a model for the British writer Stoker when he wrote vampire stories.
