Dictatorship and conflict in the USSR, 1924–53 — timeline

Key topic 1 · The leadership struggle, 1924–29

The rivals and their positions

1922

Stalin becomes General Secretary; Lenin suffers his first stroke. Why this date: The post and the vacancy arrive in the same year, which is the whole coincidence the option turns on.

December 1922 – January 1923

Lenin dictates the Testament, with the postscript proposing Stalin's removal. Why this date: The single most quotable document in the key topic.

21 January 1924

Lenin dies; Stalin organises the funeral and the cult. Why this date: Stalin appeared as chief mourner and had Lenin embalmed against the family's wishes, positioning himself as the disciple.

May 1924

The Testament is read to the Central Committee and suppressed on Zinoviev and Kamenev's argument. Why this date: The decision that saved Stalin, taken by two of his later victims.

Stalin's steps to power and the reasons for his success

1924–25

The Lenin Enrolment brings about 500,000 new members into the Party. Why this date: The electorate is remade, and it is remade by the secretariat.

January 1925

Trotsky removed as Commissar for War. Why this date: The Left's leading figure loses the one institutional base he had.

1926–27

The United Opposition forms and is expelled. Why this date: The alliance of former enemies is the clearest evidence of how completely Stalin had divided them.

1928–29

Bukharin and the Right defeated using the Left's own economic programme. Why this date: The reversal is the argument: Stalin's positions were instruments, which is why they could be exchanged.

February 1929

Trotsky deported from the USSR. Why this date: The contest is over; he was murdered in Mexico in 1940.

Key topic 2 · Five-year Plans and collectivisation

Gosplan, the Five-year Plans and the Stakhanovites

1928–32

The First Five-year Plan; declared complete in four years and three months. Why this date: The early completion is itself evidence about how targets and reporting worked.

1931

Stalin's speech: fifty to a hundred years behind, with ten years to close the gap. Why this date: The rationale in his own words, and it is ten years and two months before Barbarossa.

1932

Magnitogorsk in production; internal passports introduced. Why this date: Construction and control arrive together, which is the option's recurring shape.

August 1935

Stakhanov's 102-tonne shift. Why this date: The date and the tonnage are the precise supporting knowledge for the labour-mobilisation half of the answer.

Collectivisation, the kulaks and the Great Famine

December 1929

The liquidation of the kulaks as a class announced; forced collectivisation begins. Why this date: The policy and the terror against its opponents are announced together.

1930–31

About 1.8 million people deported as kulaks. Why this date: The scale of the deportation before the famine, which is often left out of the account.

1932–33

Several million die; grain exports continue. Why this date: The two facts have to be in the same sentence, because the argument is about the relationship between them.

7 August 1932

The law of spikelets makes taking grain from a collective field a capital offence. Why this date: It criminalises survival, in a year when the harvest is failing.

January 1933

The borders of Ukraine and the North Caucasus closed to peasants seeking food. Why this date: The decision that is central to the genocide argument, and it is documentary.

Key topic 3 · Purges, show trials, the cult of Stalin and the revision of history

Kirov, the NKVD, the gulags and the scale of the Terror

1 December 1934

Kirov murdered; an emergency decree on terrorism cases follows within hours. Why this date: The founding crime and the legal instrument, on the same day.

September 1936

Yezhov replaces Yagoda at the NKVD. Why this date: The change of personnel that marks the change from purge to mass terror.

July 1937

Order 00447 sets regional arrest and execution quotas. Why this date: The document that makes the Terror bureaucratic and therefore explicable, and it is quotable.

November 1938

The Terror is halted; Yezhov is replaced by Beria and later shot. Why this date: It stopped when the centre stopped it, which is the strongest evidence for the case from above.

The Moscow Show Trials and the purge of the armed forces

August 1936

The Trial of the Sixteen: Zinoviev and Kamenev shot. Why this date: The first trial, and the two men who had suppressed Lenin's Testament to keep Stalin in place.

January 1937

The Trial of the Seventeen: the wrecking charges. Why this date: It supplies an explanation for industrial failure that is not the plan, which is the trials' economic function.

June 1937

Tukhachevsky and seven generals tried in secret and shot. Why this date: The military purge is the consequence that reaches 1941.

March 1938

The Trial of the Twenty-One: Bukharin shot. Why this date: The last of Lenin's colleagues, convicted of plotting against Lenin.

The cult of personality and the revision of history

1929

Stalin's fiftieth birthday marks the beginning of the full public cult. Why this date: It dates the cult's start to the end of the leadership struggle, which shows what it was for.

1934

Socialist realism adopted at the Soviet Writers' Congress. Why this date: The date culture stops being permitted and starts being commissioned.

January 1936

Pravda's 'Muddle Instead of Music' attacks Shostakovich. Why this date: The clearest single case of the doctrine being enforced on a named artist.

1938

The Short Course published; over 40 million copies. Why this date: The rewritten past becomes the compulsory curriculum, and the number is quotable.

Key topic 4 · Life in the Soviet Union, 1924–41

Living and working conditions, town and countryside

1929–35

Rationing in the cities. Why this date: Six years of rationing in peacetime, during a period of rapid industrial growth.

December 1932

Internal passports introduced; collective farmers not issued with them. Why this date: The legal division between town and country, and it lasts forty-two years.

1932 and 1940

Absence criminalised; then lateness of over twenty minutes made a criminal offence. Why this date: The tightening is datable and the 1940 detail is memorable and precise.

1937–38

The Terror creates vacancies filled by rapidly promoted young officials. Why this date: The mechanism behind the regime's real base of support, and the link between key topics 3 and 4.

Women, family life and education

1920

The USSR becomes the first country to legalise abortion. Why this date: The starting point that makes 1936 a reversal rather than a policy.

1936

Abortion banned; divorce made expensive; motherhood rewarded. Why this date: The Great Retreat, and the date that makes the strand a change/continuity question.

1930s

Universal primary education achieved; examinations, uniforms and formal discipline restored. Why this date: Educational expansion and pedagogical conservatism arrive together.

1940

Female literacy has risen dramatically; women are a large share of medical and technical students. Why this date: The gain, stated with a measure, so the answer can weigh it against the loss.

The persecution of ethnic minorities

1920s

Korenizatsiya promotes non-Russian languages and cadres. Why this date: The policy that makes the 1930s a reversal, and almost no candidate has it.

August 1937

NKVD Order 00485 launches the Polish Operation. Why this date: Repression organised explicitly by nationality, with an order number.

Autumn 1937

About 172,000 Koreans deported from the Far East to Central Asia. Why this date: The first full-scale deportation of a designated nationality, in peacetime.

1943–44

Chechens, Ingush, Crimean Tatars, Kalmyks and others deported. Why this date: The wartime deportations, which the 1937 precedent shows were not improvised.

Key topic 5 · The Second World War and after, 1941–53

The setbacks of 1941–42 and the reasons the USSR survived

22 June 1941

Barbarossa begins; warnings had been repeatedly dismissed. Why this date: The scale of the surprise is a political decision, not an intelligence failure.

July–December 1941

Over 1,500 factories moved east of the Urals. Why this date: The single most important reason the USSR could keep fighting, and it is an achievement of the planned economy.

December 1941

The Soviet counter-attack before Moscow, using Siberian divisions. Why this date: The first strategic German defeat, and the end of any prospect of a short war.

1942

Soviet tank and aircraft production overtakes Germany's. Why this date: The war becomes an attrition contest the USSR is winning, which is the answer to 'why did they survive'.

The significance of Stalingrad

August–November 1942

The Sixth Army fights into the city; Chuikov holds a strip of the west bank. Why this date: The urban battle draws German forces into ground that neutralises their mobility advantage.

19–23 November 1942

Operation Uranus encircles around 250,000 men by attacking the Romanian and Hungarian flanks. Why this date: The decisive operational move was made away from the city, which most accounts underplay.

31 January – 2 February 1943

Paulus surrenders; about 91,000 prisoners taken. Why this date: A field marshal surrendering is unprecedented, and Hitler had promoted him that week expecting suicide.

18 February 1943

Goebbels' total war speech. Why this date: The clearest evidence of the effect on Germany, and it is datable to eighteen days after the surrender.

Post-war recovery, post-war purges and the USSR in 1953

1946–47

Famine kills perhaps a million after drought and unchanged procurement. Why this date: The least known fact in the key topic and one of the most useful, because it shows the system unchanged by victory.

1946

The Zhdanovshchina begins; Akhmatova and Zoshchenko denounced. Why this date: Cultural repression resumes within a year of victory, against the expectation of relaxation.

August 1949

First Soviet atomic test. Why this date: The moment the USSR becomes a superpower in the technical sense.

1949–50

The Leningrad Affair; Voznesensky shot. Why this date: The organiser of the industrial evacuation executed five years after saving the war economy.

January–March 1953

The Doctors' Plot announced; Stalin dies on 5 March; the case is dropped. Why this date: A new terror in preparation, stopped only by a death — which is the strongest evidence about where the direction came from.

June–December 1953

Beria arrested and shot. Why this date: The successors' first substantial act, and the clearest measure of how they had been living.
