Although the ruling powers in Chernevtsy changed frequently during the revolutionary years and civil war in Russia, its Jewish residents were spared the violence that generally accompanied this period. In 1937 a Jewish kolkhoz was reorganized. It was renamed “Zarya” (Dawn) and became a mixed Jewish-Ukrainian collective farm.
From the 1920s until 1939 there was a Yiddish secondary school in Chernevtsy and a Yiddish kindergarten.
In 1939 Chernevtsy's 1,455 Jews comprised 18.5 percent of the town’s total population.
Few Jewish families from the town managed to escape before Chernevtsy was occupied by German troops on July 21, 1941.
In the first week of the occupation about 20 Jewish men were murdered by Axis troops passing through the town.
In August 1941 units of Einsatzgruppe C murdered about 3,000 Jews in the area east of the Dnestr River, including an unknown number of Jews in Chernevtsy itself.
From September 1941 Chernevtsy was part of the Romanian occupation zone of Transnistria. The Jews of the town were confined to a ghetto, to which deportees from Bessarabia and Northern Bukovina were also taken. Jews were forbidden to leave the ghetto and were forced to sew yellow Stars of David onto their clothes. A Jewish council headed by a man named Soybel was set up. It had to assign ghetto inmates to various agricultural and construction jobs and to collect money and valuables from the ghetto inmates. The latter lived in crowded conditions and were subjected to constant humiliation, beatings,and confiscations. Many of them died from disease or from other results of the inhuman conditions imposed on them.
Chernevtsy was liberated by the Red Army on March 17, 1944.
