It was devastated during World War II.

Bucniowce was a miasteczko in gmina Wójtowce [uk], powiat latyczowski (later Letichevsky Uyezd, Podolian Governorate, Russian Empire), by the Zhar River [uk]. In 1880 it had population of 580, including 16 persons of odnodvortsy (petty szlachta deprived of nobility in Russian Empire after the Partitions of Poland) and 90 Jews. According to the 1897 Russian census, its population was 1265, of which 304 were Jews.
