Countess Elizabeth Báthory of Ecsed was a Hungarian noblewoman and serial killer from the powerful House of Báthory, who owned land in the Kingdom of Hungary (now Slovakia). Báthory and four of her servants were accused of torturing and killing hundreds of girls and women from 1590 to 1610. Bathory and her cohorts were charged for 80 counts of murder and were convicted. Her servants were put on trial and convicted. The servants were executed, whereas Báthory was imprisoned within the Castle of Csejte (Čachtice) until she died in her sleep in 1614.
According to scholars such as Michael Farin, the accusations against Báthory were supported by testimony from more than 300 individuals, some of whom described physical evidence and the presence of mutilated dead, dying and imprisoned girls found at the time of her arrest. Other scholars suggest that the accusations were a spectacle to destroy her family's influence in the region, which was considered a threat to the political interests of her neighbours, including the Habsburg empire.
Stories about Báthory quickly became part of national folklore.
