Bathori
Bathori, Stephen, prince of Transylvania, was elected King of Poland in 1576, and governed the country wisely for ten years, having to contend against the encroachments of Ivan the Terrible, Czar of Russia. He died at Grodno in 1586. Many members of his family during the 16th century were engaged in the struggle between the Austrians and Turks on the Danubian frontier. His niece Elizabeth, a monster of cruelty, was reputed to take baths of human blood. She was convicted of murdering 650 girls or women, and was imprisoned in the fortress of Esej, where she died in 1614.
