The area county of the county was occupied by the Soviet Union in 1940 and became part of the Ukrainian SSR. The area returned to Romanian administration following the Axis Powers' invasion of the Soviet Union in July 1941. A military administration was established and the region's Jewish population was either executed on the spot or deported to Transnistria, where further numbers were killed. As the Soviet Union's offensive pushed the Axis powers back, the area again was under Soviet control. On September 12, 1944, Romania signed the Moscow Armistice with the Allies. The Armistice, as well as the subsequent peace treaty of 1947, confirmed the Soviet-Romanian border as it was on January 1, 1941. The area of the county became part of the Ukrainian SSR and eventually of the independent Ukraine after the dissolution of the Soviet Union in 1991.
