Having stated in the November 1917 "Declaration of Rights of Nations of Russia" that any nation under imperial Russian rule should be immediately given the power of self-determination, the Bolsheviks had begun to usurp the power of the Provisional Government in the territories of Central Asia soon after the establishment of the Turkestan Committee in Tashkent. In April 1917 the Provisional Government set up the committee, which was mostly made up of former Tsarist officials. The Bolsheviks attempted to take control of the Committee in Tashkent on 12 September 1917 but it was unsuccessful, and many leaders were arrested. However, because the Committee lacked representation of the native population and poor Russian settlers, they had to release the Bolshevik prisoners almost immediately because of a public outcry, and a successful takeover of that government body took place two months later in November. The Leagues of Mohammedam Working People, which Russian settlers and natives who had been sent to work behind the lines for the Tsarist government in 1916 formed in March 1917, had led numerous strikes in the industrial centers throughout September 1917. However, after the Bolshevik destruction of the Provisional Government in Tashkent, Muslim elites formed an autonomous government in Turkestan, commonly called the "Kokand autonomy" (or simply Kokand). The White Russians supported that government body, which lasted several months because of Bolshevik troop isolation from Moscow. In January 1918 the Soviet forces, under Lt. Col. Muravyov, invaded Ukraine and invested Kiev, where the Central Council of the Ukrainian People's Republic held power. With the help of the Kiev Arsenal Uprising, the Bolsheviks captured the city on 26 January.
