Erzsébet (1560-1614) was a countess from the renowned Báthory family of Hungarian nobility. She has been labeled the most prolific female serial killer in history and is remembered as the “Blood Countess.” Elizabeth herself was neither tried nor convicted. In 1610, 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.
