The Belostok (Białystok) pogrom occurred between 14–16 June 1906 (1–3 June Old Style) in Białystok, Poland (then part of the Russian Empire). During the pogrom between 81 and 88 Jews were killed by soldiers of the Imperial Russian Army, the Black Hundreds and the Chernoe Znamia, and about 80 people were wounded. The Białystok pogrom was one of a series of violent outbreaks against Jews between 1903 and 1908, including the Kishinev pogrom, the Odessa pogrom, and the Kiev pogrom. At the beginning of the 20th century, Białystok was a city with a predominantly Jewish population. In 1895, the Jewish population numbered 47,783 (out of 62,993, or about 76%). Białystok was primarily a city known for its textile manufacturing, commerce and industry. During the 1905 Russian Revolution the city was a center of the radical labour movement, with strong organisations of the Bund and the Polish Socialist Party as well as the more radical anarchists of the Black Banner association. In the summer of 1904, an eighteen-year-old anarchist, Nisan Farber, stabbed and seriously wounded Avraam Kogan, the owner of a spinning mill, as he walked to the synagogue on Yom Kippur. On October 6, Farber threw a bomb into a police station, injuring several policemen inside. Farber himself was killed by the explosion. On February 21, 1905, the district's Chief of Police, Yelchin, was killed, and on June 8 the city's new Police Chief, Pelenkin, was wounded by another bomb blast. In July 1905, two police officers were wounded by a bomb thrown by Jewish anarchist Aron Elin (Gelinker). In the same year, police officers Mozger, Moneshko and Barancevich were killed and eight other policemen were wounded. As a consequence of the violence, martial law was declared in Białystok in September 1905, which lasted until March 1906. After martial law was lifted, the series of assassinations and acts of terror began anew. On March 4, the police officer Kulchitsky was killed, followed by the killings of gendarme officer Rubansky, and NCO Syrolevich, who were killed on March 18.
