When the Soviet Army crossed the pre-1938 borders of Czechoslovakia in 1944, Soviet authorities refused to allow Czechoslovak governmental officials to resume control over the region, and in June 1945, President Edvard Beneš formally signed a treaty ceding the area to the Soviet Union. It was then incorporated into the Ukrainian SSR. After the break-up of the Soviet Union, it became part of independent Ukraine as the Zakarpattia Oblast.
