Rise to power · 1924–29
A power struggle after Lenin
Lenin died in January 1924 without naming a clear successor. In his Testament he actually warned that Stalin was "too rude" and should be removed as General Secretary — but the Party leadership kept it secret. A struggle for control of the Communist Party followed.
The main contenders were:
Leon Trotsky — brilliant orator, hero of the Civil War, leader of the Red Army; wanted "permanent revolution".
Grigory Zinoviev & Lev Kamenev — old Bolsheviks who first allied with Stalin against Trotsky.
Nikolai Bukharin — the leading right-winger, defender of Lenin's New Economic Policy.
Joseph Stalin — the quiet General Secretary, seen by rivals as a dull "grey blur".
Key idea: Rivals underestimated Stalin. As General Secretary he controlled Party membership and appointments — the machinery that would defeat them all.
Rise to power · causation
Why Stalin won
Stalin did not win by being the most popular — he won by out-manoeuvring his rivals one by one between 1924 and 1929:
Trotsky was expelled from the Party in 1927 and exiled from the USSR in 1929.
Cause → consequence: Stalin's control of the Party machine let him engineer votes; his idea of "Socialism in One Country" beat Trotsky's "Permanent Revolution" because it promised to build up the USSR itself first.

Explain why
Why did Trotsky lose?
1Explain one reason why Trotsky, despite his talents, lost the power struggle to Stalin. Write 1–2 sentences, then reveal the model answer.
Model answer
Trotsky lost partly because he underestimated Stalin and misjudged Party opinion — for example, he missed Lenin's funeral (Stalin misled him about the date), which made him look disloyal to Lenin.
He was also distrusted as a late convert to Bolshevism and feared as a potential military dictator, so other leaders sided with Stalin against him.
Modernisation · industry
The Five-Year Plans
Stalin believed the USSR was "50 to 100 years behind" the West and must catch up or "be crushed". So he abandoned the New Economic Policy for a command economy run through Five-Year Plans, set by the state planning agency Gosplan.
First Plan (1928–32): focused on heavy industry — coal, iron, steel, oil, electricity, machinery.
Second Plan (1933–37): more heavy industry, plus new railways (e.g. the Moscow Metro) and mining.
Third Plan (1938–41): shifted towards armaments as war approached; interrupted by the German invasion.
Successes: huge new industrial cities such as Magnitogorsk; the Dnieper Dam; steel and coal output soared. Workers like the miner Alexei Stakhanov (1935) were made into propaganda heroes to drive output up.
Human cost: targets were often unrealistic, quality was poor, accidents were common, and much of the labour came from prisoners in the Gulag camps.
Quick check
What came first?
?The early Five-Year Plans prioritised which part of the economy above all else?
Watch this misconception
"The plans made life comfortable"
It is tempting to assume that a modernising economy meant better shops and homes. In fact the opposite was true for ordinary people during the 1930s.
Misconception vs reality: The Five-Year Plans prioritised heavy industry — factories, steel, power and (later) weapons — not consumer goods. Housing was cramped, food and clothing were scarce, and wages bought little. Growth was real, but it was not aimed at everyday comfort.
So when a source praises Soviet steel output, remember to ask: output of what, and at whose expense?
Modernisation · agriculture
Collectivisation of farming
To feed the new industrial cities and export grain to pay for machinery, Stalin forced peasants off their small farms into large state-controlled collective farms (kolkhozy) from 1929.
Peasants had to pool their land, tools and animals.
The state took a fixed share of the harvest at low prices.
Tractors were shared through Machine Tractor Stations.
Better-off peasants, the kulaks, resisted — so Stalin ordered them to be "liquidated as a class". Many were shot, deported to Siberia, or sent to Gulag camps. Others slaughtered their own animals rather than hand them over.
By the late 1930s almost all Soviet farmland had been collectivised.Consequence · famine
The famine, 1932–33
Collectivisation, disruption, and the state seizing grain even when harvests were poor caused a catastrophic famine in 1932–33. It hit Ukraine, the North Caucasus and Kazakhstan especially hard.
In Ukraine this man-made famine is remembered as the Holodomor ("death by hunger"). Estimates vary, but millions died — several million across the USSR, with Ukraine and Kazakhstan suffering most. Grain was still being exported while people starved.
Interpretation awareness: Historians debate whether the famine was a deliberate attack on Ukraine or a brutal by-product of Stalin's grain policy. Either way, the state's actions turned a bad harvest into mass death.

Terror · the purges
The purges & the Great Terror
The murder of the popular Leningrad Party boss Sergei Kirov in December 1934 gave Stalin the excuse to launch a wave of "purges" — removing anyone he saw as a threat.
The Great Terror (1936–38) was the peak:
Show trials in Moscow: old Bolsheviks like Zinoviev, Kamenev and Bukharin were forced to confess to invented crimes, then executed.
The Red Army was purged — most senior officers, including Marshal Tukhachevsky, were shot, leaving it dangerously weakened by 1941.
The secret police, the NKVD, arrested millions on the smallest suspicion.
Victims were shot or sent to the Gulag — a vast network of forced-labour camps.
Interpretation: The Terror created a climate of fear in which no one dared oppose Stalin. Even its organiser, NKVD chief Yezhov, was himself purged in 1939.
Watch this misconception
"The purges only hit outsiders"
Students often picture the Terror as Stalin crushing rebels and foreign spies. The reality is more disturbing.
Misconception vs reality: The purges struck the Communist Party itself hardest of all — old Bolshevik leaders, government officials, and the Red Army's own generals. Stalin turned the Terror inward, destroying the very people who had made the Revolution, so that loyalty to him replaced loyalty to the Party.
Ordinary people were also caught up: a careless word, a denunciation by a neighbour, or a family link to a "traitor" could be enough for arrest.
Quick check
The secret police
?What was the name of Stalin's secret police, who arrested victims during the Great Terror?
Explain why
Why hold show trials?
2Explain why Stalin held public "show trials" rather than simply executing his rivals in secret. Write 1–2 sentences, then reveal the model answer.
Model answer
Show trials were public propaganda: forcing famous old Bolsheviks to "confess" made Stalin's invented conspiracies look real and justified the wider Terror.
They also spread fear — if even revolutionary heroes could be exposed as "traitors", no one felt safe, so opposition to Stalin collapsed.
Control · the cult of personality
Propaganda & the cult of Stalin
Alongside terror, Stalin used propaganda to build a cult of personality — presenting himself as a wise, all-knowing father of the nation, the natural heir to Lenin.
Images everywhere: posters, statues, paintings and the renaming of cities (Stalingrad).
Rewriting history: photographs were doctored to erase "enemies" like Trotsky and to exaggerate Stalin's role in 1917.
Censorship: newspapers (like Pravda), radio and film were state-controlled; nothing critical could be printed.
Control of culture: art, music and literature had to follow "Socialist Realism", glorifying workers and Stalin.
Interpretation awareness: Because the state controlled all information, Soviet sources are heavily biased — a poster of a happy harvest tells you what Stalin wanted people to believe, not what was true.
Control · overview
How Stalin controlled the USSR
Stalin's dictatorship rested on two pillars: crushing opposition through fear, and winning obedience through persuasion.

Society · everyday life
Life in Stalin's USSR
The state reshaped everyday life, offering some real gains alongside heavy control:
Education: free schooling expanded and literacy rose sharply — but lessons were full of Stalinist propaganda, and children were urged to report "disloyal" parents.
Women: gained access to education and jobs (as doctors, engineers, factory workers) and were expected to work — yet also faced pressure to raise families, as the state reversed earlier liberal laws (divorce and abortion were restricted).
Workers: jobs were guaranteed and some had healthcare and holidays, but discipline was harsh and strikes were banned.
Religion: the officially atheist state persecuted the Orthodox Church, closing churches and arresting priests.
Balance: Stalinism brought modernisation, education and social mobility for some — but at the price of freedom, and under constant fear of the state.

War · 1941–45
The Great Patriotic War
In August 1939 Stalin signed the Nazi–Soviet Pact with Hitler. But on 22 June 1941 Germany invaded the USSR (Operation Barbarossa), beginning what Soviets call the Great Patriotic War (1941–45).
The Germans advanced fast, and the purged Red Army was caught unprepared — but the USSR survived.
Whole factories were moved east beyond the Ural Mountains, out of German reach, and the war economy poured out tanks, planes and guns.
The turning point was the brutal Battle of Stalingrad (1942–43), followed by Kursk; the Red Army then drove the Germans back.
Soviet forces captured Berlin in May 1945. Victory came at a colossal cost — around 25–27 million Soviet dead.
Effect: Victory hugely boosted Stalin's prestige. The war was used to reinforce his image as the great wartime leader who had saved the motherland.

The turning point
?Which battle is usually seen as the turning point of the war on the Eastern Front, after which the Red Army advanced towards Germany?
Post-war · to 1953
The post-war years, 1945–53
Victory did not bring relaxation. Stalin's grip actually tightened in his final years:
Rebuilding: a new Five-Year Plan (from 1946) drove reconstruction, again favouring heavy industry over consumer goods.
Renewed control: soldiers and civilians who had seen the West were viewed with suspicion; many returning prisoners of war were sent to the Gulag.
Cold War: the USSR took control of Eastern Europe and, in 1949, tested its first atomic bomb — the world split into two hostile blocs.
Late purges: fear returned with episodes such as the "Doctors' Plot" (1953), when Jewish doctors were falsely accused of a conspiracy.
Stalin died on 5 March 1953, having ruled the USSR for nearly three decades — leaving a superpower built on both extraordinary transformation and immense human suffering.
Explain why
Why did the USSR survive?
3Explain one reason why the USSR was able to defeat Germany in the Great Patriotic War. Write 1–2 sentences, then reveal the model answer.
Model answer
The USSR survived partly because the Five-Year Plans had built up heavy industry, and factories were moved east beyond German reach, so the USSR out-produced Germany in tanks, planes and guns.
The country's vast size, harsh winters and huge population, plus fierce patriotic resistance at battles like Stalingrad, also wore the invaders down.

Recap
The story to remember
Rise to power (1924–29): Stalin used the post of General Secretary and "Socialism in One Country" to defeat Trotsky and his other rivals.
Modernisation: Five-Year Plans built heavy industry; collectivisation reshaped farming but caused the 1932–33 famine (Holodomor).
Terror: the purges and Great Terror (1936–38), show trials, the NKVD and the Gulag crushed all opposition — including the Party itself.
Control: the cult of personality, propaganda, censorship and Socialist Realism won obedience.
Society: gains in education and jobs (incl. for women) alongside repression and atheist policy.
War & after: the Great Patriotic War (1941–45), victory at huge cost, then a tightening grip up to Stalin's death in 1953.
