Summary

  • The Russian Civil War (1918-1921) set the Bolshevik Reds against a loose coalition of the Whites

  • Opposition grew after the Treaty of Brest-Litovsk, Bolshevik one-party rule and the closure of the Constituent Assembly

    • The Czech Legion revolt in May 1918 helped turn opposition into a full civil war

  • Foreign powers, including Britain, France and the USA, supported the Whites

    • Their help was limited and unpopular

  • The Reds won by 1921 through their central position, unified command under Trotsky, and benefited from White disunity

  • Victory came at a cost

    • Around 10 million died

    • The war strengthened centralisation, terror and one-party rule

  • Historians debate whether the Civil War forged the Bolshevik state or mainly left Russia ruined

    • Figes argues that the totalitarian state had its origins in the Civil War

    • Pares stresses that by 1921, Russia was ruined, with industry and transport almost broken down

Causes of the Russian Civil War

Why opposition turned into a civil war

  • The Bolsheviks quickly created enemies after taking power in October 1917

    • They banned the opposition press

    • They shut out every other party except a few left-wing Socialist Revolutionaries (SRs)

    • They ruled through the Sovnarkom alone

  • Many opponents saw Bolshevik rule as a betrayal of the revolution

    • Urban workers had wanted the Soviet government, not one-party Bolshevik rule

    • The forced closure of the Constituent Assembly after one day in January 1918 enraged moderates

  • The Treaty of Brest-Litovsk became the major trigger

    • Many people welcomed the end of Russia's involvement in the First World War

    • However, Russia had to give up a large proportion of its land to Germany

      • This included around one-sixth of its population, around 62 million people

    • The treaty became a symbol of national humiliation and caused deep anger

  • Foreign powers wanted to stop Bolshevism from spreading

    • France, Britain, the USA and Japan all opposed Bolshevism

    • More importantly, they wanted Russia to reopen the Eastern Front

      • Germany now directed its fighting towards the Western Front

  • The Whites opposed the Bolsheviks, but they were a loose coalition, not a united movement

    • They included:

      • Anarchists, who opposed government altogether

      • Nationalists, who wanted independence from Russian rule

      • The SRs and Mensheviks, who wanted more democracy

      • Senior army officers, who wanted to restore tsarism

    • Their only shared aim was to bring down the Bolsheviks

The Czech Legion and the civil war

  • The Czech Legion was a foreign army trying to leave Russia

    • It was a 45,000-strong force of Czech and Slovak troops

    • They had been fighting Germany and Austria-Hungary in the war

    • They wanted to leave Russia and rejoin the fight against Germany

  • In March 1918, the Bolsheviks allowed the Legion to move east along the Trans-Siberian Railway

    • A clash in May 1918 turned the Legion against the Bolsheviks

    • Bolshevik officials tried to arrest some of the soldiers

    • Fighting broke out as the force moved along the railway

  • The revolt turned scattered opposition into a full civil war

    • The Legion seized the railway across much of the country

    • It joined forces with the anti-Bolshevik groups

    • Together, they began to advance on Moscow

    • Three years of fighting followed across the former empire

Examiner Tips and Tricks

Examiners reward precise triggers. Lead with the Treaty of Brest-Litovsk, the closure of the Constituent Assembly and the Czech Legion’s revolt, rather than saying vaguely that the Bolsheviks were unpopular.

Events of the Russian Civil War: Reds vs Whites

How the war was fought

  • The Reds held the centre while the Whites attacked from the edges

    • Red territory was based around Moscow and Petrograd

    • White forces pressed in from the east, south and northwest

  • The Whites fought on several separate fronts

    • Admiral Kolchak led the White forces in the east, in Siberia

    • General Denikin commanded the White Army in the south

    • General Yudenich attacked towards Petrograd from the northwest

  • Foreign powers backed the Whites, but only to a limited extent

    • Britain, France and the USA all sent support

    • They opposed communism and wanted Russia back in the war, fighting against Germany

    • They also resented the Bolshevik refusal to repay tsarist debts

    • Their support declined further after the First World War ended

The early fighting, 1918

  • Anti-Bolshevik forces took shape early in 1918

    • General Kornilov led the anti-Bolshevik Volunteer Army in the south

    • Socialist Revolutionaries and liberals set up a rival government at Omsk

    • By summer, the fighting had grown into a full-scale civil war

  • The Bolsheviks moved to secure their position

    • They shifted the capital from Petrograd to Moscow in March 1918

    • The Tsar and his family were shot at Yekaterinburg in July 1918

      • Local officials feared the Whites would rescue him as a figurehead

      • They feared he could be restored to the throne

  • Trotsky built the Red Army into a fighting force

    • He reintroduced conscription to raise its numbers quickly

      • This gave him an army of around 300,000 men

    • He enforced strict discipline

      • The death penalty was used for desertion or disloyalty

    • He appointed political commissars to keep units loyal

The Reds gain the upper hand, 1919-1920

  • The Whites reached the height of their success by June 1919

    • They had seized a large amount of territory

    • However, they still fought as separate forces

  • The Reds turned the tide before the end of 1919

    • They used their central position to fight the White armies one at a time

    • Kolchak pushed west from Siberia but was driven back

    • Denikin attacked from the south and threatened Moscow

      • His advance was halted and he was forced into retreat

    • Yudenich struck at Petrograd from the northwest but was pushed back

The final stage and the cost, 1920-1921

  • The last White resistance was crushed in 1920

    • General Wrangel took over from Denikin in the south

    • His forces were defeated in the Crimea in 1920

    • Nationalist uprisings, including those in Ukraine, were put down

  • The war also ended as a struggle against Poland

    • Polish forces invaded western Ukraine and reached Kiev (Kyiv) in May 1920

    • Marshal Tukhachevsky led a Red counter-offensive on Lenin's orders

    • The Poles fought back and defeated the Red Army

  • The Treaty of Riga ended the Polish war in March 1921

    • Poland gained self-rule plus Galicia and parts of Belorussia (Belarus)

    • The independence of Estonia, Latvia and Lithuania were confirmed

    • Lenin's order to drive into Poland divided the Bolsheviks

  • The Reds had won the Civil War by 1921

    • Victory came at a terrible cost

    • Around 10 million people died from hunger, disease and combat

Why did the Reds win?

Weaknesses of the Whites

  • The Whites never fought as one united force

    • Their generals operated independently

    • They were scattered across the less-developed edges of the country

    • Their separate advances could be defeated one at a time

  • The Whites had no shared goal beyond beating the Bolsheviks

    • Hatred of Bolshevism was not enough to hold them together

    • They could not agree on what Russia should become afterwards

  • The Whites struggled to win popular support

    • They were tied to unpopular tsarist-era policies

    • A lack of discipline within the White armies was common

Strengths of the Reds

  • The Reds controlled the heartland and its resources

    • They held Moscow and Petrograd, the main industrial centres

      • This gave them factories, supplies and manpower

    • They controlled the main communications and railway hubs

      • This let them move troops and equipment between fronts

  • Trotsky gave the Red Army strong, unified leadership

    • He built it into a single, disciplined fighting force

    • One command structure made the Reds better organised than the Whites

    • Trotsky personally visited the front lines and gave speeches to motivate the troops

  • Red policy won more support than the White cause

    • Red land policies to redistribute land to the peasants were generally more appealing than what the Whites offered

    • Hostility to foreign intervention worked in the Reds' favour

Examiner Tips and Tricks

Resist the urge to simply list battles. A strong answer explains how the Reds’ central position and single command became decisive advantages. The Whites were too divided and wanted different things for Russia.

Political Impacts of the Russian Civil War

The war forced power to the centre

A diagram showing the parallel party structure
  • The Civil War pushed the Bolsheviks towards tight central control

    • Survival demanded fast decisions and strict obedience

    • Terror was used systematically to crush opposition

    • Weak Bolshevik control pushed the regime towards a more centralised system

  • Real power shifted to the Party rather than the soviets

    • The Politburo, set up in 1919, became the true centre of power

    • Its first members included Lenin, Trotsky and Stalin

    • The Sovnarkom and the soviets met and mattered less

A militarised, swollen state

  • Government grew into a vast bureaucracy during the war

    • There were twice as many officials as workers in Soviet Russia

    • These officials became the main social base of the new regime

  • The Party took on a permanent military style

    • It spoke in terms of front, battles and campaigns

    • It treated all opponents as enemies to be hunted down

    • This habit of command and struggle outlasted the war

Tighter rule over the people and minorities

  • The state moved away from earlier promises after the war

    • Self-determination for national minorities was dropped

    • Independence movements were branded as counter-revolutionary

    • Georgia's demands for independence were crushed in 1922

  • Bolshevik authority was rebuilt as one centralised union

    • The RSFSR became the USSR in December 1922

      • In theory, it was a federation of equal republics

      • In practice, Moscow kept firm control over them all

Examiner Tips and Tricks

Do not treat the Civil War as only a military conflict. Its biggest political impact was that it changed how the Bolsheviks governed. Central control, terror, bureaucracy and Party discipline all became normal during the war, and many of these methods remained afterwards.

The strongest answers link emergency wartime measures to the later one-party state. The Politburo, the growth of bureaucracy, the weakening of the soviets and the creation of the USSR all show power moving away from popular democracy and towards centralised Party control.

How Important Was the Russian Civil War to the Success of Bolshevism?

  • The Civil War secured Bolshevik power

    • But historians disagree about how far it explains the regime that followed

The Civil War forged the Bolshevik state

  • The war turned a fragile takeover into a hardened regime

    • Victory gave the Bolsheviks a powerful founding myth

    • It proved the Party could survive against the odds

    • It removed rival parties and armed opponents

  • The war built the tools the regime would continue using

    • The Red Army became a mass, disciplined force

    • Terror and central planning became normal in these years

    • The militarised command style outlasted the fighting

  • The state that emerged was shaped by the war for decades

    • Bureaucracy ballooned to 5.4 million officials by 1920

    • The habits of struggle and command became permanent

Key historian

“The totalitarian state had its origins in the civil war, when it was necessary to control every aspect of the economy and society. For this reason the Soviet bureaucracy ballooned spectacularly during the civil war. By 1920, 5.4 million people worked for the government. There were twice as many officials as there were workers in Soviet Russia and these officials were the main social base of the new regime. This was not a dictatorship of the proletariat but a dictatorship of the bureaucracy. The civil war became a model of success and shaped political habits until 1941.”

O. Figes, Revolutionary Russia (2014)

  • Figes argues that the Civil War, not 1917 alone, created the centralised and bureaucratic state of Soviet rule

    • This supports the view that the war was decisive in shaping what Bolshevism became

The war's importance lay in its cost, not its strength

  • Bolshevik victory owed much to White failure

    • The Whites were divided and scattered from the start

    • The Reds simply held the centre and outlasted them

    • This was survival as much as positive achievement

  • The human and economic cost was huge

    • Around 10 million people died across the conflict

    • Industry was reduced to a fraction of its former size

    • The country was left exhausted and close to collapse

  • The damage created crises the regime could not ignore

    • War Communism triggered famine and bitter unrest

    • These pressures forced the retreat to the New Economic Policy (opens in a new tab)

    • The cost of victory shaped the hard choices that followed

Key historian

“By 1921 Russia was ruined. The ruin had begun in the First World War. It grew in dimensions under the Provisional Government. The wild, initial experiments of the Bolsheviks were fast completing it. Fantastic inflation and hopeless deficits marked the abandonment of all conventional principles of exchange. Industry was more than five sixths gone. Transport had worn out most of its existing reserves and, in the failure of repair and production, except for military purposes it had broken down almost completely.”

B. Pares, A History of Russia (1949)

  • Pares stresses the scale of devastation by 1921

    • Industry and transport were almost destroyed

    • This supports the view that the war’s true importance lay in the ruin it left behind, not in any positive strength it gave the Bolsheviks

Examiner Tips and Tricks

With this type of question, decide what “success” means before judging. Surviving the war, tightening one-party rule and building a state that lasted are not the same thing. The Civil War can look more or less important depending on which definition you use. Aim for a clear, supported view rather than leaving both sides evenly balanced.
