Dzyarzhynsk or Dzerzhinsk; formerly Koidanova or Koydanava (Belarusian: Дзяржы́нск Dziaržynsk [dzʲarˈʐɨnsk]; Russian: Дзержинск, Polish: Kojdanów; Yiddish: קוידנוב, Koidanov, Lithuanian: Kaidanava), in the Dzyarzhynsk Raion of Belarus, is a city with a history dating to the 11th century.
Koidanova became the site of a new Hasidic Jewish dynasty in 1833 when Rabbi Shlomo Chaim Perlow (1797–1862) became the first Koidanover Rebbe. He was succeeded by his son, Rabbi Boruch Mordechai Perlow (1818–1870), grandson, Rabbi Aharon Perlow (1839–1897), and great-grandson, Rabbi Yosef Perlow of Koidanov-Minsk (1854-1915), who was the last Koidanover Rebbe to live in the town. After World War I, the dynasty was moved to Baranovichi, Poland.
In May 1932 it was granted the status of a city and was renamed Kojdanaŭ (Belarusian: Койданаў), Russian: Koidanov. In June of that year it was renamed again as Dziaržynsk by the Communist authorities, in honor of Felix Dzerzhinsky (1877–1926), a famous Bolshevik creator and chief of the "Cherezvychainaya Komissija" (CHEKA) – the Soviet secret police -who was born in a Dziaržynava estate not far from the city.
World War II
It fell under German occupation during World War II. It was captured on June 28, 1941.
The Lithuanian Twelfth Schutzmannschaft (auxiliary police) Battalion's 1st Company, led by Lieutenant Z. Kemzura, massacred between 1,000 and 1,900 Jews from the city on October 21, 1941, shooting them and throwing them into a pit; many were buried alive. As it is reported in The Complete Black Book of Russian Jewry: "For three hours the earth covering the mass grave would move; people still alive were trying to crawl out of their grave." In July 1942, the Einsatzgruppen killed several thousand Jews in Koidanov. The city was liberated by the Soviet Red Army on July 6, 1944.
In 1998, the city had 24,700 inhabitants.
The highest point of Belarus, Dziaržynskaja Hara, is several kilometers from Dziaržynsk.
There is a railway road across the city from Minsk Passazhirsky to Baranovichi Polesskie.
There is only one bus route in Dziarzhynsk, that has 18 stops.
