Hertza region
Chernivtsi oblast was created on August 7, 1940 in the wake of the Soviet occupation of Bessarabia and Northern Bukovina. The oblast was organized out of the northeast part of Ținutul Suceava of Kingdom of Romania, joining parts of three historical regions: northern half of Bukovina, northern half of the Hotin County county of Bessarabia, and Hertza region, which was part of the Dorohoi county (presently Botoșani County) of proper Moldavia.
