The Russian Revolution (1917–1923)

Mass strikes and bread riots in Petrograd escalated into a full-scale revolution when soldiers of the Petrograd garrison mutinied and joined the protesters. The Duma, defying the tsar's order to dissolve, established a Provisional Government under Prince Georgy Lvov. Tsar Nicholas II, isolated and without military support, abdicated on 15 March (2 March Old Style), ending 304 years of Romanov rule. A dual power structure emerged between the Provisional Government and the Petrograd Soviet of Workers' and Soldiers' Deputies.

Vladimir Lenin arrived at Petrograd's Finland Station after a decade in exile, transported through Germany in a sealed train. Upon arrival, he delivered his April Theses, calling for the overthrow of the Provisional Government, the transfer of all power to the soviets, and an immediate end to Russia's participation in World War I. The Bolsheviks, initially a minority faction, gained support among workers, soldiers, and peasants with their promises of "Peace, Land, and Bread" and "All Power to the Soviets."

Spontaneous armed demonstrations by soldiers and workers in Petrograd demanded that the Soviet seize power from the Provisional Government. The Bolshevik leadership initially hesitated but then supported the protests. The government, now led by Alexander Kerensky, crushed the uprising, accusing the Bolsheviks of being German agents. Lenin fled to Finland, and Leon Trotsky and other Bolshevik leaders were arrested. The crackdown temporarily set back the Bolshevik cause, but the failed uprising also discredited the moderate socialists who had joined the government.

General Lavr Kornilov, Commander-in-Chief of the Russian Army, attempted a military coup against the Provisional Government, marching troops toward Petrograd to restore order. In desperation, Kerensky released the Bolshevik leaders from prison and armed the Red Guards to defend the capital. The railway workers and Bolshevik agitators stopped Kornilov's troops, and the coup collapsed. The affair fatally weakened the Provisional Government, discredited the military leadership, and dramatically strengthened the Bolsheviks, who were seen as the saviors of the revolution.

Under Lenin's direction and organized by Leon Trotsky's Military Revolutionary Committee, Bolshevik Red Guards and revolutionary sailors from the cruiser Aurora stormed the Winter Palace, arrested the Provisional Government, and declared Soviet power. The Second All-Russian Congress of Soviets immediately approved the decrees on peace and land, nationalizing land and calling for an end to World War I. The October Revolution, virtually bloodless in Petrograd, established the world's first socialist state and set in motion the events that would shape the 20th century.

The Bolshevik government signed the Treaty of Brest-Litovsk with the Central Powers, withdrawing Russia from World War I. The treaty ceded vast territories including Poland, the Baltic states, Finland, Ukraine, and parts of the Caucasus to the Central Powers, losing approximately 34% of the Russian Empire's population and 89% of its coal mines. Despite the harsh terms, Lenin argued that peace was necessary to preserve the Bolshevik government. The treaty was nullified after Germany's defeat in November 1918.

Following the October Revolution, a multi-sided civil war erupted between the Bolshevik Red Army (led by Leon Trotsky) and the anti-Bolshevik White forces, which included monarchists, liberals, socialists, and foreign intervention forces from 14 countries. The war, which lasted until 1922, spread across the former Russian Empire, from Siberia to Ukraine. The Red Army's centralized command, use of former tsarist officers, and control of the industrial heartland and railway network eventually gave it the advantage. The war caused immense suffering, including famine, disease, and the execution of the Romanov family.

The former Tsar Nicholas II, his wife Alexandra, their five children, and four loyal servants were executed by a Bolshevik firing squad in the basement of the Ipatiev House in Yekaterinburg. The execution was ordered by the Ural Regional Soviet, fearing that the approaching White Army might liberate the imperial family. The bodies were secretly buried in a forest and not discovered until 1979. The execution of the Romanovs removed a potential figurehead for the White forces and marked the final end of the Russian monarchy.

In March 1921, sailors and soldiers at the Kronstadt naval fortress, previously among the most ardent supporters of the Bolsheviks, rose up against the Communist government. They demanded free elections, freedom of speech, an end to the one-party state, and the abolition of the Cheka (secret police). Trotsky personally ordered the Red Army to crush the rebellion, which was done after a bloody assault that killed thousands. The Kronstadt rebellion marked a turning point, revealing the deep disillusionment with Bolshevik rule among the very groups that had brought it to power.

In March 1921, at the Tenth Party Congress, Lenin announced the New Economic Policy (NEP), a strategic retreat from the radical policies of War Communism. The NEP restored limited private enterprise, allowed peasants to sell surplus grain on the open market, and permitted small-scale trade and manufacturing. The policy aimed to revive the devastated Russian economy and defuse peasant unrest that had grown into widespread rebellions. The NEP succeeded in restoring production to pre-war levels by the mid-1920s, though it was condemned by orthodox Marxists as a concession to capitalism.

The Treaty on the Creation of the USSR was signed, establishing the Union of Soviet Socialist Republics as a federation of the Russian SFSR, the Transcaucasian SFSR, the Ukrainian SSR, and the Byelorussian SSR. The treaty created a centralized federal government while formally granting each republic the right to secede. The establishment of the USSR formalized the Bolshevik victory in the civil war and the consolidation of the world's first socialist state, which would become one of the two superpowers of the 20th century.
