Ukrainian People's Republic
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. It formally declared its independence from Russia on 22 January 1918.
