The short answer is that Russia had a pair of revolutions in 1917, which led to a civil war and the withdrawal of Russia from the war.
The significantly longer answer:
In the early 1900s, Russia was (and still is) a huge country, the largest on the planet. It was very backwards, and did not have a fully modern military or infrastructure. It was ruled by an old-fashioned, autocratic Tsar (emperor), who did not believe in modern political concepts like democracy or elections. There was a major rebellion in 1905, and in order to end it, the Tsar allowed the formation of a Duma (parliament). But he never really gave the Duma any power, so in reality, he didn't actually do anything for his people, and they were not happy about it. The Tsar was somewhat deluded, however- he saw himself as a sort of father figure to his people, and assumed that they would simply trust his judgement and obey him.
When Russia got involved in World War I, it was very unsuccessful in its fight against Germany (although it did do well against Austria-Hungary); in the first few months of the war, one German army nearly destroyed two much larger Russian armies in turn, at Tannenburg and then Masurian Lakes. This poor showing, along with shortages of food and fuel, quickly made the war wildly unpopular among the common people. Communists took advantage of this to further upset the population, portraying the war as just a bunch of old kings, emperors, and wealthy capitalists using poor people to fight and die over resources and colonies (which, to be fair, isn't terribly far from the truth). Eventually, the Tsar went off to personally command his armies in the hope that his presence would inspire his soldiers to fight better (it didn't work). He left behind his Tsarina (empress) to rule, and she was not well-liked by the Russian people.
So in mid-February 1917, riots broke out in St. Petersburg, the capital at the time. Workers in the city were upset at food shortages, and went on strike. When the furious Tsar ordered soldiers to kill them, most of the soldiers chose instead to mutiny and joined the protesters, and the protests grew. Within a few weeks, the government had fallen and the Tsar abdicated his throne. A republic was set up, but already there were signs of a trouble- Communists (who usually called themselves "Socialists" at the time) were trying to set up their own government while a more Western-style republic was put in place. So there were in effect two governments- the many Communist-style "Soviets" (workers' councils) in the cities, and the parliamentary "Provisional Government", which tried to rule the whole country.
The Provisional Government decided to keep fighting the war, despite its unpopularity. Additionally, Vladimir Lenin, the fiery leader of the Bolshevik faction of the Russian Communists, returned from exile and began working with the Soviets to bring down the government. There were more protests in the spring and summer of 1917, which were brutally crushed by the government. The last straw was when the government accused the commander in chief of the Russian military of trying to take over the country, which of course, led him to actually try rather than be arrested. The government asked the Communists and the Soviets to help stop him, which they did, and the commander was defeated- but the Communists and Soviets had become very powerful in the process.
In early November 1917, the Communists finally overthrew the Provisional Government in the October Revolution, or "Red October" (Russia used a different kind of calendar at the time, and for them, it was still October; also, red is the color of Communism). The Red Guards, the volunteer soldiers of the Bolshevik party, assaulted the palace where the government worked, thereby ending it. A terrible civil war began, fought primarily by the following factions (all named after colors), especially the first two:
Lenin's Bolsheviks took control and tried to set up a new government based on the Soviets. With the Russian army severely weakened by the two revolutions, the civil war, and Communist efforts to disband it (since it was loyal to the Tsar and not to them), the Bolsheviks sought to end Russia's involvement in the war, but could not agree on exactly how to go about it. While the Bolsheviks stalled, the Central Powers took advantage and began occupying large chunks of western Russia. Eventually, in March 1918, the Bolsheviks agreed to peace with the Central Powers; Russia would officially give up the territory that the Central Powers had occupied, and in return, Russia would be allowed to peacefully exit the war.
Side notes to end the story- the Civil War continued for several years after 1917. When World War I ended, the Allies, including the United States, briefly sent troops to help the Whites- the Tsar and his family were murdered by the Bolsheviks in summer 1918 because the Bolsheviks were afraid that a nearby Czech army was about to free them. Anyway... because the Whites had a lot of leaders, and these leaders usually refused to work together, the well-organized and motivated Reds were eventually able to crush them. At the end of 1922, the civil war was pretty much over (except for some rogue White leaders way out in Siberia and Mongolia), and the victorious Bolsheviks officially created the Soviet Union, the world's first Communist country, with Lenin as its leader.
AnswerLenin.His full name was Valdimir Ilyich Lenin.
MY TEACHER TOLD ME THAT DURING WW1 RUSSIA WAS STARVING THEY WERE LOSING MONEY ALSO WENT INTO A BIG DEPRESSION WICH MADE THEM DROP OUT THE WAR
In November 1917 the Bolshevists, headed by Lenin, seized power in Russia. This led to civil war in Russia, and the West intervened in an attempt to oust the Communists. All western countries were anti-Communist in the inter-war period.
Imperialism led to conflict over colonial resource, labor, and markets (APEX)
Russia helped Serbia throughout most of the war. Being the largest army in the world at the time, it used much of its forces to defend its "little brother" Serbia. Eventually, Russia had to withdraw from the war due to the communist revolution in Russia led by Vladimir Lenin.
Russia had to withdraw from the war due to the communist revolution in Russia led by Vladimir Lenin.
The Bolshevik Revolution was the event that led to Russia's early exit from World War 1. It was a costly war for Russia.
Stalin led Russia in WW2.
World War 2 it was Stalin and World War 1 it was Lenin
Vladimir Lenin led the Bolsheviks to revolution in Russia during WWI
No one led Russia after Lenin in World War I. Lenin ended Russia's involvement in World War I by signing the Treaty of Brest-Litovsk in 1918. World War I ended several months later in 1919. Lenin remained fully in power after the war ended.
World War 2 it was Stalin and World War 1 it was Lenin
because a revolution, led be V.I. Lenin, was starting. it was called the Bolshevic/Russian Revolution. russia withdrew from the war to take care of the problems within the country.
Vladimir Lenin led Russia after World War 1. In 1922 he was partially disabled by a stroke and couldn't participate in running the government. After that Russia was run by Joseph Stalin, Grigori Zinoviev and lev Kamenev until Lenin died on January 21, 1924.
Russia was invaded by Germany..............................
The October or Bolshevik Revolution of 1917 is the event that ultimately led to the Russian withdrawal from World War 1. The Treaty of Brest-Litovsk in 1918 was the formal end to Russia's involvement.
Kerensky, who led Provsional Government. Lenin was able to gain support to overthrow that government because he promised to withdraw from the war if he and his Bolsheviks gained power. Lenin made good on that promise with the Treaty of Brest-Litovsk.
