Immediately after the October Revolution in Petrograd, Bolsheviks instigated the Kyiv Bolshevik Uprising to support the Revolution and secure Kyiv. Due to a lack of adequate support from the local population and anti-revolutionary Central Rada, however, the Kyiv Bolshevik group split. Most moved to Kharkiv and received the support of the eastern Ukrainian cities and industrial centers. Later, this move was regarded as a mistake by some of the People's Commissars (Yevgenia Bosch). They issued an ultimatum to the Central Rada on 17 December to recognise the Soviet government of which the Rada was very critical. The Bolsheviks convened a separate congress and declared the first Soviet Republic of Ukraine on 24 December 1917 claiming the Central Rada and its supporters outlaws that need to be eradicated. Warfare ensued against the Ukrainian People's Republic (UPR) for the installation of the Soviet regime in the country and with the direct support from Soviet Russia the Ukrainian National forces were practically overran. The government of Ukraine appealed to foreign capitalists, finding the support in the face of the Central Powers as the others refused to recognise it. After the Treaty of Brest-Litovsk, the Russian SFSR yielded all the captured Ukrainian territory as the Bolsheviks were forced out of Ukraine. The government of the Soviet Ukraine was dissolved after its last session on 20 November 1918.
