In 1940, following the Molotov–Ribbentrop Pact and the Soviet ultimatum on 26 June 1940, Northern Bukovina (including all of Storojineț County) was occupied by the Soviet Union and incorporated into the USSR (Chernivtsi Oblast, Ukrainian SSR). Storojineț 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 Northern Bukovina was took over again by the Soviet Army and the borders as of 1 January 1941 were confirmed by the 1947 Paris Peace Treaties.
