Kronstadt Rebellion (1921)
크론시타트 봉기
An armed insurrection in March 1921 by sailors, soldiers, and civilians of the Kronstadt naval base against Bolshevik one-party rule and the policies of War Communism. Under the slogan 'All power to the Soviets, not to parties,' the rebels demanded freely re-elected soviets by secret ballot, freedom of speech and press for left-wing parties, the release of political prisoners, and full freedom for peasants to use their land and trade their grain. The uprising forced the Bolshevik leadership to confront the bankruptcy of War Communism and directly accelerated the shift to the New Economic Policy (NEP); Lenin judged the crisis 'undoubtedly more dangerous than Denikin, Yudenich, and Kolchak combined.'

The Kronstadt Rebellion
Why did Kronstadt, the red fortress of the October Revolution, turn its guns on that revolution's government in March 1921?
The Kronstadt Rebellion was an armed uprising of sailors, soldiers, and civilians at the Baltic Fleet's main base on Kotlin Island from 1 to 18 March 1921. With the Civil War effectively over yet War Communism's forced grain requisitions, ration cuts, and political repression persisting, the sailors of Kronstadt adopted the Petropavlovsk Resolution demanding free soviet elections, freedom of speech and assembly, amnesty for political prisoners, and peasants' right to dispose of their land. The Bolshevik leadership refused negotiations, branded the rebellion a White conspiracy, and crushed it in two assaults across the frozen Gulf of Finland. About 8,000 rebels fled to Finland; over 2,100 prisoners were summarily executed.
Were the Sailors of 1921 the Same Men Who Made October?
When the Bolshevik leadership branded the rebellion a counterrevolutionary conspiracy, one of its arguments rested on a claim about personnel. In "Hue and Cry Over Kronstadt," Leon Trotsky argued that a large turnover had occurred in the Baltic Fleet during the Civil War, and that "the old-timers had been replaced by conscripts from the rural districts": politically backward peasant recruits from Ukraine and the western borderlands. If true, the Kronstadt garrison of 1921 was no longer the revolutionary force that had stormed the Winter Palace in 1917, and its mutiny represented not the continuation of October's ideals but peasant grievances in uniform.
Israel Getzler tested this claim against the fleet's own muster rolls in his 1983 study Kronstadt 1917-1921. Of 2,028 sailors on the two battleships at the heart of the revolt, the Petropavlovsk and the Sevastopol, whose year of enlistment could be established, 1,904 (93.9 percent) had been recruited before or during the 1917 revolution. The largest group, 1,195 men, had enlisted in 1914-16. Only 137 (6.8 percent) were recruits from 1918-21. Furthermore, of a planned 10,384 new recruits for the Baltic Fleet, only 1,313 had actually arrived by 1 December 1920. Getzler concluded that across the entire garrison, at least three-quarters of the sailors on active duty were veterans who had been drafted before 1918. His regional analysis reinforced the finding: roughly 10 percent came from Ukraine, while over 80 percent were from Great Russian areas.
Paul Avrich, in his 1970 book Kronstadt 1921, acknowledged that Getzler's archival work was based on more current data than his own and revised his figures accordingly. Avrich went further: to refute the claim by Trotskyist Ted Grant that "a cursory glance at the surnames of the mutineers immediately shows that they were almost all Ukrainians," he analyzed hundreds of participants' surnames. The overwhelming majority were Great Russian. Of the 15 members of the Provisional Revolutionary Committee, only three (Petrichenko, Yakovenko, and Romanenko) bore identifiably Ukrainian names.
What the archival numbers do not settle, however, is whether continuity of personnel means continuity of politics. Even in 1917, most Kronstadt sailors were of peasant origin. By 1921, according to official figures, more than three-quarters were peasants, a substantially higher proportion than in 1917, when industrial workers from the Petrograd area had made up a sizable part of the fleet. The same men may have held the same guns, but four years of civil war and War Communism had ravaged the Russian countryside, and their politics may have changed with it. Stepan Petrichenko himself later acknowledged that when he visited his native Ukrainian village in April 1920 and saw the Bolshevik food detachments in action, he returned to Kronstadt with a deep hostility toward the government he had once served.
The archives say this: the massive personnel replacement that the Bolshevik leadership claimed did not happen. The men who took up arms at Kronstadt in 1921 were, for the most part, the same men who had made revolution there in 1917. But why those same men turned those same guns on that same government four years later is a question that continuity of personnel alone cannot answer. It must be sought in what the four years between had done to them.
The War Was Over: Why Were the Rations Cut?
When Wrangel's White Army was driven from Crimea in November 1920, the Russian Civil War was effectively over. More than eight million had died in three years and industrial production had collapsed to one-fifth of its 1913 level, but the Bolshevik regime had survived. Workers, peasants, and sailors now expected the emergency wartime measures to be lifted. The opposite occurred.
War Communism had begun as a temporary wartime policy, but it was reinforced after the fighting stopped. The grain requisitioning system (prodrazvyorstka) remained in place, and armed requisitioning detachments continued to sweep through villages, taking even seed grain. In the autumn of 1920 Lenin himself conceded that 'we actually took from the peasants not only their surpluses but sometimes even part of the grain needed for food.' Peasants began refusing to sow their fields. By February 1921 the Cheka counted 118 peasant uprisings across the country. The largest, the Antonov rebellion in Tambov province, drew 50,000 guerrillas into a near-civil war. In Western Siberia, 100,000 insurgents fought under the slogan 'Down with Communism! Long live the Soviets!'
The cities fared worse. In January 1921 the government cut bread rations by one-third for all urban areas. The official explanation, that heavy snow and fuel shortages prevented food transport from Siberia and the Caucasus, convinced no hungry worker. Petrograd was hit hardest. On 11 February the city soviet announced the closure of 93 enterprises, including the giant Putilov and Sestroretsk plants, for lack of fuel. The city's population had collapsed from 2.5 million in 1917 to roughly 750,000 by August 1920, and those who remained survived on 200 to 800 grams of black bread a day.
On 23 February, workers at the Trubochny Factory on Vasilyevsky Island adopted a resolution demanding increased rations and the immediate distribution of winter clothing and footwear reportedly reserved for Bolsheviks. The next morning, 200 to 300 workers marched to the Laferme tobacco factory, the Baltic Works, and the Kabelny plant, calling workers out on strike. A crowd of some 2,500 gathered on the island. Zinoviev's Defense Committee declared martial law on 25 February and sent armed cadets to disperse the unarmed demonstrators, firing into the air on this occasion. But the strikes spread across the city, and political demands, including freedom of speech, press, and assembly, secret-ballot soviet elections, and release of political prisoners, began to overtake the economic ones.
At an expanded session of the Petrograd Soviet on 26 February, Defense Committee member Lashevich identified the Trubochny Factory as 'the vanguard of open action against Soviet power' and ordered it closed. At the same session, Baltic Fleet Political Commissar Nikolai Kuzmin delivered a more ominous warning: unless the 'strike agitation' (volynka) in Petrograd was stopped, an 'explosion' on the fleet was imminent. His words would prove prophetic within two days.
On 27 February the authorities made concessions. Worker and soldier rations were raised to a pound and a quarter of bread and a tin of meat daily, the roadblock detachments around Petrograd province were withdrawn, and workers were permitted to leave the city to bring back food from the countryside. These measures brought most factories back to work by early March, though as the American consul noted, they 'blew a serious hole in Petrograd's food reserves.' Simultaneously, the Cheka arrested some 500 worker activists, hundreds of students and intellectuals, and key figures of the Mensheviks, including Fyodor Dan, along with anarchists and Socialist Revolutionaries.
The Petrograd strikes were outwardly subdued, but their shockwave had already traveled the thirty kilometers across the frozen Gulf of Finland to Kronstadt. Sailors of the battleships Petropavlovsk and Sevastopol dispatched a fact-finding mission to the city to see for themselves what was happening.
"The Soviets Do Not Express the Will of the Workers and Peasants": From Resolution to the Square
On 26 February 1921, the crews of the battleships Petropavlovsk and Sevastopol, moored side by side in Kronstadt's frozen harbour, held an emergency meeting. Word had reached the island that striking workers in Petrograd were surrounded by troops. The sailors decided to see for themselves. What the delegation found was shocking. Factories were ringed by soldiers and military cadets; inside the workshops still in operation, armed Communist detachments kept watch over the workers. Stepan Petrichenko, who would soon chair the Provisional Revolutionary Committee, later wrote: "One might have thought these were not factories but the forced-labour prisons of the tsarist era." When the delegation approached, the workers fell silent. A factory committee chairman called a meeting so the men could hear a report from Kronstadt, but none of the workers stirred. The silence was fear.
On 28 February, the delegation returned to the Petropavlovsk and reported what they had seen to an assembly on deck. The sailors were outraged. On the spot, they drew up a resolution of fifteen demands. The first article said everything: "In view of the fact that the present soviets do not express the will of the workers and peasants, immediately to hold new elections by secret ballot, with freedom to carry on agitation beforehand for all workers and peasants." There followed: freedom of speech and press for workers, peasants, anarchists, and left socialist parties; freedom of assembly for trade unions and peasant organizations; a non-party conference of workers, Red Army soldiers, and sailors of Petrograd, Kronstadt, and Petrograd Province no later than 10 March; release of all political prisoners of socialist parties and all those imprisoned in connection with the labour and peasant movements; a commission to review the cases of those held in camps; abolition of the political departments, since no party should receive special privileges or state funds to propagate its ideas, to be replaced by locally elected cultural-educational commissions; immediate removal of the roadblock detachments that confiscated food; equalisation of rations for all working people except those in hazardous trades; abolition of Communist fighting detachments in the army and Communist guards in factories; peasants' full freedom to use their land and keep livestock without hired labour; and permission for free handicraft production.
It is striking that only one of the fifteen demands, the abolition of political departments, concerned the fleet's own affairs. The rest were for the striking workers of Petrograd and the peasants rising across the country. The resolution was adopted unanimously, with two abstentions. Petrichenko presided; Perepelkin was secretary.
The following day, 1 March, a mass assembly called by the Kronstadt Soviet convened in Anchor Square. Fifteen to sixteen thousand people gathered. The authorities, hoping to calm the crowd, sent Mikhail Kalinin, chairman of the All-Russian Central Executive Committee, to speak. Grigori Zinoviev, the Petrograd party boss, got only as far as Oranienbaum: he was afraid to set foot on the island. Kalinin was received with applause, but the mood turned the moment he began to argue against the resolution. The crowd shouted him down: "Give it up, Kalinych, you're well fed," "How many posts do you hold, and draw pay from all of them?," "We know what we need, old man. Go back to your wife." The fleet commissar Nikolai Kuzmin followed him to the platform, denounced the sailors as counter-revolutionaries, and threatened that their "treason would be smashed by the iron hand of the proletariat." He was booed off the stage. Kalinin and Kuzmin cast the only two votes against the resolution in the entire assembly. The Petropavlovsk Resolution was adopted by an overwhelming majority.
Kalinin was allowed to leave the island, though the insurgent guards initially refused to let him go. Shortly after his departure, Kuzmin was discovered to have ordered the removal of all food and munitions from Kronstadt and was arrested. Two days later, on 2 March, back in Petrograd, it was Kalinin who first spread the false report that the rebellion was a White Guard plot led by General Kozlovsky, the story the Bolsheviks would use to justify crushing the men they had once called the pride and glory of the revolution.
The Revolutionary Committee Was No Planned Coup: From Handover to Ultimatum
The delegate assembly of 2 March was not convened to stage a coup. With the Kronstadt Soviet's mandate expired, some 300 delegates from the ships, units, unions, and workshops met at the House of Education to fix the procedure for fresh soviet elections. Communists sat among the opening speakers, and Baltic Fleet commissar Kuzmin and Kronstadt executive-committee president Vasiliev were given the floor again. By Petrichenko's account, Kuzmin insisted Petrograd was calm, invoked the Polish threat, and declared that 'the Communists would not withdraw from power voluntarily and would fight to their last forces.' As the two men's speeches only stoked resentment, the delegates escorted them out of the hall.
What actually created the Provisional Revolutionary Committee was not a political resolution but an urgent rumor. From the moment the 1 March rally ended, local Communists had been demanding rifles and machine guns from the arsenal and arming themselves, and word spread that armed Communists were approaching the assembly. The meeting voted that its own presidium should assume the Committee's duties at once, and so the body chaired by Petrichenko took over the city without a single shot. The 326 detained Bolsheviks were about a fifth of the local party membership; they received the same rations as the crews and suffered no torture or execution.
The government's response was never of one voice. Kalinin considered the rebels' demands 'acceptable with only minor changes,' and the Petrograd Soviet tried to coax the sailors as men 'misled by counterrevolutionary agents.' But on 2 March an order signed by Lenin and the newly returned Trotsky left no room for conciliation. It branded the revolt a 'Black Hundreds / SR' mutiny engineered by 'former general Kozlovsky' at the hands of 'French counter-intelligence,' outlawed Kozlovsky, and placed all of Petrograd province under siege.
The Kozlovsky myth was the first volley of that propaganda war. He was an artillery specialist appointed by Trotsky himself; the Revolutionary Committee ignored every one of his offensive recommendations (an assault on Oranienbaum, breaking the ice, building barricades), and when the fortress commander fled, he declined the post and took on only technical artillery work. Victor Serge testified that Kalinin had invented the story right after returning from Anchor Square.
On 5 March, an ultimatum signed by Trotsky was dropped over the island: surrender immediately and unconditionally or be 'shot like partridges.' Simultaneously the Cheka began rounding up the rebels' relatives as hostages, the very tactic Trotsky had used against ex-Tsarist officers in the Civil War. The rebels shot back that their own prisoners enjoyed full liberty and would not be released while Petrograd held families hostage, and the hostage gambit doomed the period's sole mediation attempt as well. Kronstadt held the guns, but it waited on the frozen gulf trusting only that the government would offer negotiations first.
Why the Seventh Army hurried across the ice
Kronstadt was a fortress at sea, and the ice in early March offered the government a short-lived road to it. Once the ice melted, an army could not approach in the same way, while the rebels might receive supplies or outside assistance through the Baltic. The refusal to negotiate was therefore not merely a matter of prestige. The Petrograd strikes had not entirely subsided, and Kronstadt's demands were expressed in the language of soviets and socialism rather than in a White restorationist program. Every day the fortress endured could alter the political balance on the mainland. The Bolshevik leadership saw a political breach in the military rear of the revolution and, after the ultimatum of 5 March, placed Mikhail Tukhachevsky in command of the Seventh Army.
The hurry, however, created an operational weakness. Coastal batteries and aircraft bombarded the fortress on 7 March, but bombardment alone could not silence an island defended by two battleships and shore guns. In the first assault on 8 March, Red Army troops had to cross open ice. A snowstorm and darkness concealed the advance but also made it difficult to keep direction, while the fortress guns and machine guns broke the ice. Some soldiers refused to advance or fell back, and men from some units crossed over to the rebels. This was not simply a failure to obey orders. For soldiers exhausted by the civil war, being ordered by the “workers' and peasants' government” to fire on sailors of the same revolution exposed a political contradiction that weakened their will to fight.
The rebels did not turn the opportunity into victory either. Trusting the fortress's guns and defensive position, they waited for the government to attack first and did not pursue the retreating troops or break out toward the mainland. The failed first assault therefore produced no negotiations. It hardened both sides' calculations. The government concluded that wavering units could not be trusted, and prepared to lead the next attack with more reliable troops and delegates from the Party Congress. The sailors, meanwhile, learned that shellfire, rather than argument, was being used to erase their demands. The fighting of 7 and 8 March did not yet mean the fall of Kronstadt. It marked the moment when an argument inside the revolution began to be subordinated to a military timetable.
After the Fortress Fell, Whom Did the Revolution Punish?
The second assault was not merely an operation to capture a fortress. What the leadership in Moscow feared was not only Kronstadt’s artillery, but the restoration of a political link between the rebel sailors and the workers of Petrograd. The assault force therefore received not just reinforcements but a layer of politically trusted coercion. From the night of 16 March into the early hours of the 17th, Mikhail Tukhachevsky’s troops crossed the ice from several directions, with soldiers in white camouflage, cadet units, Cheka detachments, and Communist volunteers from the Tenth Party Congress at the front. To the attackers, this was a harsh but necessary measure to defend the revolution’s gains. If spring melted the ice, the fortress could be supplied by sea and its defenses strengthened, while unrest in Petrograd might join the island’s resistance. The rebels, by contrast, believed they were restoring the soviet power of 1917, but they did not seize the initiative and march on Petrograd. Their long-range guns and fortress defenses could not compensate for an exhausted garrison fighting in isolation. Red Army troops broke through after heavy losses in the street fighting of 17 March, and the last resistance ended the following morning. Official Soviet figures listed 527 dead and 3,285 wounded, while an unofficial estimate by the American consulate put total losses at about 10,000. The discrepancy reflects different ways of counting men who disappeared on the ice and losses from the first assault.
Once defeat was certain, about 8,000 people crossed the ice into Finland. They included Stepan Petrichenko and members of the Provisional Revolutionary Committee, and the retreat was less an organized exile than an emergency flight from arrest and execution. The crews of the battleships remaining in the harbor learned that their leaders had refused orders to scuttle the ships and fled; they arrested the officers and surrendered. The episode shows that the rebellion had not retained a unified command to the end. The refugees in Finland continued to bear the political cost imposed by the state even after the war. The Soviet government later offered amnesties, but some of those who returned were executed or sent to forced-labor camps. Punishment inside the fortress also proceeded in ways that blurred the line between combat and repression. Soviet case statistics record 2,103 death sentences and 6,459 forced-labor sentences, while contemporary reports and later scholarship estimate that about 2,000 people were executed summarily, without trial. Suppression therefore did not end with the military victory of 18 March. The Bolsheviks described the operation as the removal of a counterrevolutionary conspiracy, yet those punished included not only officers allegedly directed by foreign powers, but sailors, soldiers, and workers who had demanded new soviet elections and freedom for the left. Some of Kronstadt’s political demands were soon absorbed into the change of economic policy, but the people who had voiced them were silenced or driven abroad. That asymmetry most clearly shows what the victory of 1921 preserved, and what it discarded.
Grain Conceded, the Party Closed: Kronstadt's Two Legacies
To say that Kronstadt directly produced Moscow's decision reverses the sequence. Replacing grain requisitioning with a tax in kind had been discussed before the revolt, and at the Tenth Congress Lenin argued that Soviet power itself might collapse unless the alliance between workers and peasants was repaired. Yet passing the measure while party members were attacking their own party's fortress changed its political meaning. Adopted on March 15, the resolution allowed peasants to dispose of and trade the grain left after paying the tax. It abandoned the expectation that War Communism could serve as a permanent shortcut to communism and offered small farmers a material incentive to resume production. Trotsky likewise explained that War Communism had arisen from military necessity rather than an economic principle, but this economic concession did not come with the rebels' demand for political reconstruction of the soviets.
The party's door, instead, became narrower. The March 16 Resolution “On Party Unity” ordered the immediate dissolution of all factions and groups and empowered the Central Committee, as an exceptional measure, to expel members engaged in factional activity. For Lenin and many other leaders, this was a defensive line in a besieged workers' state, meant to prevent open disagreement from becoming a passage for military enemies. About 300 Congress delegates volunteered to suppress Kronstadt, and ten of them were killed. But the same defensive line also removed an institution through which criticism inside the party could be organized. Moscow thus returned a limited market to peasants in the economic sphere while rejecting the demand to separate the soviets from the party in the political sphere. The later judgment that this resolution became a weapon against Stalin's rivals is necessarily informed by hindsight, but it is difficult to deny that the choice opened a channel from crisis management to concentrated power.
After the Soviet collapse, the state legally reread this legacy. On January 10, 1994, Boris Yeltsin's presidential decree rehabilitated participants in the “Kronstadt events of spring 1921.” This did not politically adopt the rebels' program. It was a later legal judgment that reversed the Soviet courts' punishments as unjust state repression. Kronstadt therefore has two endings. In 1921, economic policy was revised at the same moment that political closure was imposed; in 1994, the legitimacy of the punishment produced by that closure was reversed. Rehabilitation discarded the official explanation that those defeated on the ice were counter-revolutionaries, but it did not mean that their demand for soviet democracy had been realized.
What Kronstadt Settled, and What It Did Not
Kronstadt settled a first question politically. In March 1921, the Soviet state answered armed workers and sailors demanding new soviet elections and public activity for the left not through negotiation, but through military force and punishment. The rebels' own language was not a manifesto for restoring capitalism. In a declaration published on 8 March by the Provisional Revolutionary Committee's newspaper, they called the uprising "the third revolution," one that would break the last fetters on the working masses. That language shows that they believed they were defending the promises of 1917 against party bureaucracy, not abandoning the revolution. Yet their choice, made amid military isolation, hesitation by the leadership, and the ebb of the Petrograd workers' movement, left them unable to avoid defeat and reprisals. Kronstadt established both that soviet democracy was not self-enforcing and that a revolutionary government could silence its own social base by force.
The event did not, however, prove that the completed dictatorship of the Bolsheviks was inevitable. The New Economic Policy had already been under discussion in the party leadership before the revolt, so Kronstadt did not invent the policy. But Lenin's report to the 10th Party Congress, where he described peasant discontent and Kronstadt together as a crisis of the regime, shows that the rebellion changed the speed and political meaning of the turn. The ban on factions, passed alongside the economic concession, also shows that material retreat and political closure came as a pair.
Historians still disagree at this point. Paul Avrich treated the rebellion as a spontaneous uprising of people exhausted by war and requisitioning. Israel Getzler, using fleet muster rolls and party records, stressed that the 1921 sailors were not wholly cut off from the men who had made 1917. Leon Trotsky's 1938 defense argued instead that the military danger and the Petrograd workers' withdrawal made suppression unavoidable. Tobin Shorey's 2003 study adds a different emphasis: the rebels used Bolshevik revolutionary vocabulary to reclaim representation of the "true October." The unresolved question, then, is not whether the rebels were simply good or bad. It is how far the soviet democracy they could have built might have extended, how serious the danger from external counterrevolution actually was, and whether military necessity could justify political repression. The settled result was the double outcome of suppression and concession. What remains unsettled is whether another choice was possible at that moment.
Consequences
In the suppression's wake, 2,103 rebels were sentenced to death and 6,459 sent to forced labor camps; the families of survivors were deported to Siberia. The Bolsheviks, facing what Lenin called a crisis "undoubtedly more dangerous than Denikin, Yudenich, and Kolchak combined," accelerated the abandonment of War Communism at the 10th Party Congress, adopting the New Economic Policy. The congress also banned factional activity within the party, and by year's end the anarchists, Socialist Revolutionaries, Mensheviks, and other left-wing rivals were suppressed. Of the roughly 8,000 rebels who escaped to Finland, many later accepted Soviet offers of amnesty, only to be executed or sent to camps. In 1994, President Boris Yeltsin issued a decree officially rehabilitating the participants of the Kronstadt Rebellion.

- 1921.02.24Petrograd Strikes
After bread rations were cut by one-third, workers at Petrograd's Trubochny Factory went on strike. The movement spread to other factories. Zinoviev's Defense Committee declared martial law and dispersed protests with armed cadets.
- 1921.02.28The Petropavlovsk Resolution
Crews of the battleships Petropavlovsk and Sevastopol, after investigating the Petrograd strikes, declared that "the present soviets do not express the will of the workers and peasants" and adopted 15 demands: secret-ballot soviet elections, freedom of speech and press for left socialist and anarchist groups, release of political prisoners, abolition of party political departments, peasants' right to dispose of their land, and more.

A delegate assembly of some 300 elected a 5-member (later 15-member) Provisional Revolutionary Committee chaired by Stepan Petrichenko after arresting the Kronstadt Soviet president and fleet commissar. By nightfall, the city, ships, and forts were in rebel hands without bloodshed. 326 local Bolsheviks were detained.
- 1921.03.05Trotsky's Ultimatum
A leaflet signed by Trotsky was dropped over Kronstadt: surrender immediately and unconditionally or be "shot like partridges."

Tukhachevsky, reinforced to 45,000 men and led by some 300 volunteers from the 10th Party Congress alongside Cheka detachments and cadet regiments, advanced in six columns at 3 a.m. After a full day of street fighting on 17 March, the last resistance was crushed by the following morning. Soviet losses were officially 527 dead and 3,285 wounded, though the American consul at Vyborg estimated total Bolshevik casualties at around 10,000.
- 1921.03.188,000 Flee to Finland; Reprisals Begin
About 8,000 rebels, including the leadership, fled across the ice to Finland. The battleship crews, upon discovering their officers had deserted, disobeyed orders to scuttle the ships, arrested the officers, and surrendered. On 20 March, the first 13 summary executions were carried out; ultimately 2,103 were sentenced to death and 6,459 to forced labor.
- 1921.03.1510th Party Congress: NEP and the Ban on Factions
With Kronstadt under bombardment, the 10th Party Congress passed Lenin's resolution to abandon War Communism and replace grain requisitioning with a tax in kind, the New Economic Policy (NEP). Though NEP had been drafted before the rebellion, the combined shock of Kronstadt and the Tambov peasant uprising accelerated its adoption. Simultaneously, a resolution "On Party Unity" banned all factional activity within the Bolshevik Party.
- 1994.01.10Yeltsin Rehabilitates the Kronstadt Rebels
Russian President Boris Yeltsin issued a decree rehabilitating participants of the "Kronstadt events of spring 1921" and declaring the Bolshevik suppression illegal. Yet as late as the 2010s, the Kronstadt Fortress Museum had not updated its exhibits to reflect this rehabilitation.
