The Hilsner Affair (also known as the Hilsner Trial, Hilsner Case or Polná Affair) was a series of anti-semitic trials following an accusation of blood libel against Leopold Hilsner, a Jewish inhabitant of the town of Polná in Bohemia, Austria-Hungary in 1899 and 1900. The affair achieved widespread media publicity at the time.
Anežka Hrůzová was a 19-year-old Czech Catholic girl, living in the village of Věžnička. She worked as a seamstress in Polná, 2 miles (3.2 km) away. On the afternoon of 29 March 1899, she left her place of employment as usual, but did not return to her home. Three days later (1 April) her body was found in a forest, her throat having been cut and her garments torn. Nearby was a pool of blood, some blood-stained stones, parts of her garments, and a rope with which she had been either strangled to death or dragged, after the murder, to the place where the body was found.
The suspicion of the sheriff was first turned against four vagrants who had been seen in the neighborhood of the forest on the afternoon of the day when the murder was supposed to have been committed. Among them was Leopold Hilsner, a 23-year-old Jew, a man of little intelligence, who had been a vagrant all his life. Suspicion against him was based on the fact that he had been frequently seen strolling in the forest where the body was found. A search of his house showed nothing suspicious. He claimed to have left the place on the afternoon of the murder long before it could have been committed; but he could not establish a perfect alibi. Hilsner was arrested, and tried at Kutná Hora on 12–16 September. He denied all knowledge of the crime. The only physical evidence against him was a pair of trousers on which some stains were found, which chemical experts said might have been blood, while the garment was wet as if an attempt had been made to wash it. One witness against him claimed to have seen Hilsner, at a distance of 2,000 feet (610 m), in company with two strange Jews, on the day on which the murder was supposed to have been committed and on the spot where the body was found. Another witness claimed to have seen him come from that place on the afternoon of 29 March and to have noticed that he was very much agitated. Both the prosecuting attorney, and the attorney for the Hrůza family, Karel Baxa, made clear suggestions of ritual murder. Testimony had proved that Hilsner was too weak to have committed the crime by himself. Still he was sentenced to death for participation in the murder, while his supposed accomplices were undiscovered and no attempt was made to bring them to justice.
