In 1919, the northern Mhlyn, Novozybkiv, Starodub, and Surazh counties of Chernihiv Governorate, with their mixed Ukrainian–Belarusian–Russian population, were transferred from Ukraine to the newly established Gomel Governorate of the Russian republic. In February 1924, Tahanrih and Shakhty counties (Tahanrizka okruha and Shakhtynska okruha) were transferred from the Donetsk guberniia of the Ukrainian SSR to the North Caucasus krai of the Russian SFSR.
