Alexander Kerensky in the context of "1917 October Revolution"

The Russian Republic, referred to as the Russian Democratic Federative Republic in the 1918 Constitution, was a short-lived state which controlled, de jure, the territory of the former Russian Empire after its proclamation by the Russian Provisional Government on 1 September (14 September, N.S.Tooltip New Style) 1917 in a decree signed by Alexander Kerensky as Minister-Chairman and Alexander Zarudny as Minister of Justice.

The government of the Russian Republic was dissolved after the Bolsheviks seized power by force on 7 November 1917. Nonetheless, a partially democratic election of the Constituent Assembly still took place later in November. On 18 January 1918, this assembly issued a decree, proclaiming Russia a democratic federal republic, but was also dissolved by the Bolsheviks on the next day after the proclamation.

The Russian Provisional Government was a provisional government of the Russian Empire and Russian Republic, announced two days before and established immediately after the abdication of Nicholas II on 2 March, O.S. [15 March 1917, N.S.], during the February Revolution. The intention of the provisional government was the organization of elections to the Russian Constituent Assembly and its convention. The provisional government, led first by Prince Georgy Lvov and then by Alexander Kerensky, lasted approximately eight months, and ceased to exist when the Bolsheviks gained power in the October Revolution in October [November, N.S.] 1917.

According to Harold Whitmore Williams, the history of the eight months during which Russia was ruled by the Provisional Government was the history of the steady and systematic disorganization of the army. The Provisional Government was a caretaker government, with its political system and the status of the monarchy remaining unresolved until the election of the Constituent Assembly. This was finally clarified on 1 September [14 September, N.S.], when the Russian Republic was proclaimed, in a decree signed by Kerensky as Minister-President and Zarudny as Minister of Justice.

The Socialist Revolutionary Party (SR; Russian: Па́ртия социали́стов-революционе́ров, romanized: Pártiya sotsialístov-revolyutsionérov,, lit. 'Party of Socialists-Revolutionaries') was a major socialist political party in the late Russian Empire, during both phases of the Russian Revolution, and in early Soviet Russia. The party members were known as Esers (эсеры, esery, from "SRs").

The SRs were agrarian socialists and supporters of a democratic socialist Russian republic. The ideological heirs of the Narodniks, the SRs won a mass following among the Russian peasantry by endorsing the overthrow of the Tsar and the redistribution of land to the peasants. The SRs boycotted the elections to the First Duma following the Revolution of 1905 alongside the Russian Social Democratic Labour Party, but chose to run in the elections to the Second Duma and received the majority of the few seats allotted to the peasantry. Following the 1907 coup, the SRs boycotted all subsequent Dumas until the fall of the Tsar in the February Revolution of March 1917. Controversially, the party leadership endorsed the Russian Provisional Government and participated in multiple coalitions with liberal and social-democratic parties, while a radical faction within the SRs rejected the Provisional Government's authority in favor of the Congress of Soviets and began to drift towards the Bolsheviks. These divisions would ultimately result in the party splitting over the course of the fall of 1917, with the emergence of a separate Party of Left Socialist Revolutionaries. Meanwhile, Alexander Kerensky, one of the leaders of the February Revolution and the second and last head of the Provisional Government (July–November 1917) was a nominal member of the SR party but in practice acted independently of its decisions.

The October Revolution, also known as the Great October Socialist Revolution (in Soviet historiography), October coup, Bolshevik coup, or Bolshevik revolution, was the second of two revolutions in Russia in 1917. It was led by Vladimir Lenin's Bolsheviks as part of the broader Russian Revolution of 1917–1923. It began through an insurrection in Petrograd (now Saint Petersburg) on 7 November 1917 [O.S. 25 October]. It was the precipitating event of the Russian Civil War. The initial stage of the October Revolution, which involved the assault on Petrograd, occurred largely without any casualties.

The October Revolution followed and capitalised on the February Revolution earlier that year, which had led to the abdication of Nicholas II and the creation of the Russian Provisional Government. The provisional government, led by Alexander Kerensky, had taken power after Grand Duke Michael, the younger brother of Nicholas II, declined to take power. During this time, urban workers began to organize into councils (soviets) wherein revolutionaries criticized the provisional government and its actions. The provisional government remained unpopular, especially because it was continuing to fight in World War I, and had ruled with an iron fist throughout mid-1917 (including killing hundreds of protesters in the July Days). It declared the Russian Republic on 1 [N.S. 14] September 1917.

The Decree on the system of government of Russia was a basis of the new constitution declared in 1918 in Russia during the Russian Revolution of 1917, during the five-month interregnum between the downfall of the Alexander Kerensky government and the official declaration of the Russian Socialist Federative Soviet Republic. It was formally declared on 18 January 1918 when the democratically elected Russian Constituent Assembly drafted and adopted the "Resolution on the form of government of Russia," declaring Russia to be a democratic federal republic called the "Russian Democratic Federative Republic." However, the Assembly was dissolved on the same day by the Bolshevik-controlled All-Russian Central Executive Committee, meaning the declaration was not carried out as it was considered to be without legal force.

The Directorate (Kerensky Second Government) was the short-lived transitional government of Russia during the Russian Revolution. It consisted of five main ministers and lasted for about three weeks.

The Provisional Committee of the State Duma (Russian: Временный Комитет Государственной Думы) was a special government body established on March 12, 1917 (27 February O.S.) by the Fourth State Duma deputies at the outbreak of the February Revolution in the same year. It was formed under the jurisdiction of the Russian Provisional Government, established immediately after the abdication of Nicholas II.

The committee declared itself the governing body of Russian Empire, but competed for power with the Petrograd Soviet, which was created on the same day. The Government of Golitzine as the Council of Ministers of Russian Empire retreated to the Admiralty building. The committee of the State Duma appointed 24 commissars to head various state ministries replacing the Imperial Government. According to Milyukov Chkheidze never participated in the work of the committee.
