Minister-Chairmen of the Russian Provisional Government

Approximately 98 people have been head of the Russian government since its establishment in 1726. The chairman of government was a member of the Supreme Privy Council, which was created on 8 (19) February 1726 by Empress Catherine, and from 8 (20) September 1802 ministerial duties were allocated by the Committee of Ministers, which was established on in accordance with the proclamation of Emperor Alexander II. Beginning with Count Aleksandr Romanovich Vorontsov, the eldest of the officers was de facto chairman of the committee. Eight years after the inauguration of the manifest, the first de jure office holder was Count Nikolay Rumyantsev. The Council of Ministers was unofficially formed in October 1857, as a result of Emperor Alexander II's reforms; its first session began on 19 (31) December 1857. Before the actual formation of that body on 12 (24) November 1861, the Emperor himself was in charge. The Council of Ministers consisted of chairmen of the State Council and the Committee of Ministers, as well as high-ranking officers appointed by the Emperor. The first session ended on 11 (23) December 1882, after the number of files to the Council greatly decreased.

The Committee of Ministers functioned simultaneously with the second session of the Council of Ministers for six more months; Count Sergei Witte participated on both entities until the abolition of the committee on 23 April (5 May) 1906. Following that event, the duties of the committee were left to the Council of Ministers, until the formation of the Small Council in 1909, which also included deputy ministers. By the order of Emperor Nicholas II, the second session of the Council of Ministers began on 19 October (1 November) 1905, following the formation of the State Duma. Shortly after the February Revolution and the inception of the Russian Provisional Government on 2 (15) March 1917, Georgy Lvov from the Constitutional Democratic Party and Alexander Kerensky from the Socialist Revolutionary Party became joint Minister-Chairmen. The provisional Russian Republic was eventually replaced by the Russian Soviet Federative Socialist Republic (RSFSR) and the governmental body by the Council of People's Commissars, which was chaired from 1917–24 by Vladimir Lenin. That body was renamed Council of Ministers following a decree of the Supreme Council on 23 March 1946.
