Chudniv (uk|Чуднів, pl|Cudnów, yi|טשודנאוו, ru|Чуднов) is a city in Zhytomyr Raion, Zhytomyr Oblast, Ukraine. Prior to 2020, it was the administrative center of the former Chudniv Raion. Population:
A significant battle of the Russo-Polish War (1654–1667) was fought near the town in 1660, followed by a treaty between the Polish–Lithuanian Commonwealth and the Cossacks, named after the city. In 1866 Polish Romantic-era novelist Henryk Rzewuski died in Chudniv. The Jewish population was important in the town. During World War II, the Germans occupied the town and kept the Jews imprisoned in a ghetto. In 1941, they were murdered in mass executions perpetrated by an Einsatzgruppen of Germans and Ukrainian policemen.[1]
