Chernigov Governorate was an administrative-territorial unit (guberniya) of the Russian Empire. It was officially created in 1802 from the disbanded Little Russia Governorate and had its capital in Chernigov.
Its borders encompassed the modern Chernihiv Oblast, but also included a large section of Sumy Oblast and smaller sections of the Kyiv Oblast of Ukraine, in addition to a large part of Bryansk Oblast of Russia.
The Ukrainian People's Republic (UPR) was a short-lived state in Eastern Europe. Prior to its proclamation, the Central Council of Ukraine was elected in March 1917 as a result of the February Revolution, and in June, it declared Ukrainian autonomy within Russia. Its autonomy was later recognized by the Russian Provisional Government. Following the October Revolution, the Central Council of Ukraine denounced the Bolshevik seizure of power and proclaimed the Ukrainian People's Republic with a territory including the area of approximately eight Russian imperial governorates (Kiev, Volhynia, Kharkov, Kherson, Yekaterinoslav, Poltava, Chernigov and Podolia). It formally declared its independence from Russia on 22 January 1918.
During its short existence, the republic went through several political transformations – from the socialist-leaning republic headed by the Central Council of Ukraine with its general secretariat, to the socialist republic led by the Directorate and by Symon Petliura. Between April and December 1918, the socialist authority of the Ukrainian People's Republic was suspended, having been overthrown by the pro-German Ukrainian State of Pavlo Skoropadskyi, who was elected as the Hetman of Ukraine by a congress of peasants. After the collapse of the Ukrainian State, the Ukrainian People's Republic declared its unification with the West Ukrainian People's Republic in January 1919. After the Polish–Ukrainian War, it signed an alliance with the Second Polish Republic. On 10 November 1920, the state lost the remainder of its territory to the Bolsheviks. The Peace of Riga on 18 March 1921 between Poland, Soviet Russia (acting also on behalf of Soviet Belarus), and Soviet Ukraine sealed the fate of the Ukrainian People's Republic.
