The October Revolution, also known as the Great October Socialist Revolution, October coup, or Bolshevik coup was a revolution in Russia led by the Bolshevik Party of Vladimir Lenin that was a key moment in the larger Russian Revolution of 1917–1923. It was the second revolutionary change of government in Russia in 1917. It took place through an armed insurrection in Petrograd on 7 November 1917 [O.S. 25 October]. It was the precipitating event of the Russian Civil War.
The Russian Revolution was a period of political and social change in the Russian Empire, starting in 1917. This period saw Russia abolish its monarchy and adopt a socialist form of government following two successive revolutions and a bloody civil war. The Russian Revolution can also be seen as the precursor for the other European revolutions that occurred during or in the aftermath of World War I, such as the German Revolution of 1918–1919.
The Russian Civil War was a multi-party civil war in the former Russian Empire sparked by the overthrowing of the social-democratic Russian Provisional Government in the October Revolution, as many factions vied to determine Russia's political future. It resulted in the formation of the Russian Socialist Federative Soviet Republic and later the Soviet Union in most of its territory. Its finale marked the end of the Russian Revolution, which was one of the key events of the 20th century.
The Treaty of Brest-Litovsk was a separate peace treaty signed on 3 March 1918 between Soviet Russia and the Central Powers, by which Russia withdrew from World War I. The treaty, which followed months of negotiations after the armistice on the Eastern Front in December 1917, was signed at Brest-Litovsk.
A provisional government, also called an interim government, an emergency government, a transitional government or provisional leadership, is a temporary government formed to manage a period of transition, often following state collapse. Provisional governments are generally appointed, and frequently arise, either during or after civil or foreign wars, or during difficult times such as during invasion, economic crisis, or widespread infiltration of saboteurs and counter-revolutionaries such as during the French Revolution.
The Russian Republic, referred to as the Russian Democratic Federal 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 1917 in a decree signed by Alexander Kerensky as Minister-Chairman and Alexander Zarudny as Minister of Justice.
The time period of around 1985–1991 marked the final period of the Cold War. It was characterized by systemic reform within the Soviet Union, the easing of geopolitical tensions between the Soviet-led bloc and the United States-led bloc, the collapse of the Soviet Union's influence in Eastern Europe, and the dissolution of the Soviet Union in 1991.
The military history of Europe refers to the history of warfare on the European continent. From the beginning of the modern era to the second half of the 20th century, European militaries possessed a significant technological advantage, allowing its states to pursue policies of expansionism and colonization until the Cold War period. European militaries in between the fifteenth century and the modern period were able to conquer or subjugate almost every other nation in the world. Since the end of the Cold War, the European security environment has been characterized by structural dominance of the United States through its NATO commitments to the defense of Europe, as European states have sought to reap the 'peace dividend' occasioned by the end of the Cold War and reduce defense expenditures. European militaries now mostly undertake power projection missions outside the European continent. Recent military conflicts involving European nations include the 2001 War in Afghanistan, the 2003 War in Iraq, the 2011 NATO Campaign in Libya, and various other engagements in the Balkan and on the African continent. After 2014, the Russian annexation of Crimea and the ongoing Russo-Ukrainian War prompted renewed scholarly interest into European military affairs. For further the context see History of Europe.
A soviet republic, or council republic is a republic in which the government is formed of soviets and politics are based on soviet democracy.
A referendum on the Act of Declaration of Independence was held in Ukraine on 1 December 1991. An overwhelming majority of 93% of voters approved the declaration of independence made by the Verkhovna Rada on 24 August 1991. Voters were asked "Do you support the Act of Declaration of Independence of Ukraine?" The text of the Declaration was included as a preamble to the question. The referendum was called by the Parliament of Ukraine to confirm the Act of Independence, which was adopted by the Parliament on 24 August 1991. Citizens of Ukraine expressed overwhelming support for independence. In the referendum, 31,891,742 registered voters took part, and among them 28,804,071 voted "Yes".
Pro-independence movements in the Russian Civil War within the territory of the former Russian Empire sought the creation of independent and non-Bolshevik nation states after the October Revolution, therefore being in direct conflict with the Russian Soviet Republic which sought to conquer them. They were often supported politically or militarily by the Entente Powers. Some of them co-operated with the Russian White movement, but others were in conflict with it. Many pro-independence movements emerged after the dissolution of the Russian Empire and fought in the Russian Civil War.
In many periodizations of human history, the late modern period followed the early modern period. It began around 1800 and, depending on the author, either ended with the beginning of contemporary history in 1945, or includes the contemporary history period to the present day.
The Russian Soviet Federative Socialist Republic, previously known as the Russian Soviet Republic and the Russian Socialist Federative Soviet Republic, as well as being unofficially referred to as Soviet Russia, the Russian Federation, or simply Russia, was an independent federal socialist state from 1917 to 1922, and afterwards the largest and most populous constituent republic of the Soviet Union (USSR) from 1922 to 1991, until becoming a sovereign part of the Soviet Union with priority of Russian laws over Union-level legislation in 1990 and 1991, the last two years of the existence of the USSR. The Russian SFSR was composed of sixteen smaller constituent units of autonomous republics, five autonomous oblasts, ten autonomous okrugs, six krais and forty oblasts. Russians formed the largest ethnic group. The capital of the Russian SFSR and the USSR as a whole was Moscow and the other major urban centers included Leningrad, Stalingrad, Novosibirsk, Sverdlovsk, Gorky and Kuybyshev. It was the first socialist state in the world.
The history of Soviet Russia and the Soviet Union (USSR) reflects a period of change for both Russia and the world. Though the terms "Soviet Russia" and "Soviet Union" often are synonymous in everyday speech, when referring to the foundations of the Soviet Union, "Soviet Russia" often specifically refers to brief period between the October Revolution of 1917 and the creation of the Soviet Union in 1922.
The Revolutions of 1917–1923 were a revolutionary wave that included political unrest and armed revolts around the world inspired by the success of the Russian Revolution and the disorder created by the aftermath of World War I. The uprisings were mainly socialist or anti-colonial in nature. Some socialist revolts failed to create lasting socialist states. The revolutions had lasting effects in shaping the future European political landscape, with for example the collapse of the German Empire and the dissolution of Austria-Hungary.
A revolutionary wave or revolutionary decade is one series of revolutions occurring in various locations within a similar time-span. In many cases, past revolutions and revolutionary waves have inspired current ones, or an initial revolution has inspired other concurrent "affiliate revolutions" with similar aims. The causes of revolutionary waves have become the subjects of study by historians and political philosophers, including Robert Roswell Palmer, Crane Brinton, Hannah Arendt, Eric Hoffer, and Jacques Godechot.
World communism, also known as global communism or international communism, is a form of communism placing emphasis on an international scope rather than being individual communist states. The long-term goal of world communism is an unlimited worldwide communist society that is classless, moneyless, stateless, and nonviolent, which may be achieved through an intermediate-term goal of either a voluntary association of sovereign states as a global alliance, or a world government as a single worldwide state.
Dissolution in politics is when a state, institution, nation, or administrative region dissolves or ceases to exist, usually separating into two or more entities, or being annexed. This can be carried out through armed conflict, legal means, diplomacy, or a combination of all or any of the three. It is similar to dissolution in the legal sense.
"Address concerning the events in Ukraine" was a televised address by Russian President Vladimir Putin on 21 February 2022, announcing that the Russian government would recognise the Ukrainian separatist regions of the Donetsk People's Republic and the Luhansk People's Republic as independent. During the speech, Putin also made a number of claims regarding Ukrainian history and Ukrainian domestic politics. The speech, which marked a significant escalation in the culminating Russo-Ukrainian crisis, was followed three days later by another speech declaring "a special military operation" in Ukraine—announcing the Russian invasion of Ukraine.
