In 1940, following the Molotov–Ribbentrop Pact and the Soviet ultimatum on 26 June 1940, Northern Bukovina (including the whole Cernăuți County) was occupied by the Soviet Union and incorporated into the USSR (Chernivtsi Oblast, Ukrainian SSR). Cernăuți County was re-established (as part of the Bukovina Governorate) after Northern Bukovina was recovered by Romania in July 1941, following the invasion of the Soviet Union. Nevertheless, in August 1944 the Northern Bukovina was taken over again by the Soviet Army, and the borders as of 1 January 1941 were confirmed by the 1947 Paris Peace Treaties.
