Darja Nikolajevna Saltyková

Darya Nikolayevna Saltykova, commonly known as Saltychikha, was a Russian noblewoman from the Saltykov family, sadist, and serial killer from Moscow. She became notorious for torturing and killing many of her serfs, mostly women. Saltykova has been compared by many to the Hungarian "Blood Countess," Elizabeth Báthory (1560–1614), who allegedly committed similar crimes in her home, Čachtice Castle, against servant girls and local serfs, although historians debate the accuracy of these charges.
