Edexcel IGCSE History: Dictatorship and Conflict in the USSR, 1924–53 (4HI1)

“Dictatorship and conflict in the USSR, 1924–53” is Depth Study 5 on Paper 1 of Pearson Edexcel International GCSE History (4HI1). It covers how Stalin won the struggle to succeed Lenin, transformed the Soviet economy through industrialisation and collectivisation, ruled through terror and propaganda, and led the USSR to victory in the Second World War before his death in 1953. As with every depth study, you answer one question in three parts: extract impression, two effects and a 16-mark essay.

Syllabus coverage

The 4HI1 specification (Issue 5, February 2026) sets five key topics:

1. The leadership struggle, 1924–29 — the rivals (Stalin, Trotsky, Kamenev, Bukharin, Zinoviev), the strengths and weaknesses of Stalin and Trotsky, Stalin’s steps to power and the reasons for his success.
2. Five-year Plans and collectivisation — Stalin’s economic aims, the failings of the NEP, Gosplan, the first three Five-year Plans, Stakhanovites, successes and failures; collectivisation, kolkhozes, Motor Tractor Stations, the kulaks and the famine of 1932–33.
3. Purges, show trials, the cult of Stalin and the revision of history — the murder of Kirov, the purges, Yezhov, the NKVD and the gulags, the Moscow Show Trials (1936–38), the purge of the armed forces; the cult of personality, censorship, socialist realism, education and the Soviet interpretation of history.
4. Life in the Soviet Union, 1924–41 — living and working conditions in town and countryside, social groups, family life, women, education and the persecution of ethnic minorities.
5. The Second World War and after, 1941–53 — Soviet setbacks in 1941–42, survival and victory, war production, Stalingrad, post-war recovery and the Fourth Five-year Plan, Stalin’s popularity, post-war purges and the USSR’s strength in 1953.

How did Stalin win the leadership struggle?

Lenin died in January 1924. His “Testament” warned that Stalin was too rude to be General Secretary, but it was not published. Trotsky — creator of the Red Army and a brilliant speaker — seemed the obvious successor, but he was seen as arrogant, had joined the Bolsheviks only in 1917, and missed Lenin’s funeral. Stalin, General Secretary since 1922, controlled appointments and built support among party officials.

Stalin allied with Zinoviev and Kamenev to remove Trotsky as Commissar for War (1925). His policy of “Socialism in One Country” appealed more than Trotsky’s “Permanent Revolution”. When Zinoviev and Kamenev joined Trotsky in opposition, Stalin, now backed by Bukharin and the Right, had them expelled from the party (1927); Trotsky was exiled in 1928 and deported in 1929. Stalin then turned on Bukharin over the NEP, and by 1929 he was unchallenged. Reasons for his success: control of the party machine, skill at playing rivals off against each other, popular policies and his opponents’ mistakes.

Why and how did Stalin transform the economy?

Stalin believed the USSR was “fifty or a hundred years behind the advanced countries” and had to catch up within ten years or be crushed. The NEP had allowed private trade and left grain supply in peasant hands; the grain procurement crisis of 1927–28 convinced him it had failed.

Industrialisation was planned by Gosplan through the Five-year Plans (1928–32, 1933–37 and 1938–41, the last interrupted by war). They concentrated on heavy industry — coal, steel, oil and electricity — with huge projects such as Magnitogorsk and the Dnieper dam. In 1935 the miner Alexei Stakhanov was credited with cutting over 100 tonnes of coal in a single shift, and “Stakhanovites” were held up as models. Successes: output of heavy industry rose rapidly and the USSR built the base that later won the war. Failures: poor-quality goods, waste, few consumer goods, harsh labour discipline and the use of forced labour.

Collectivisation from 1929 merged peasant farms into kolkhozes (collective farms), which received machinery from Motor Tractor Stations. The kulaks (better-off peasants) resisted, were declared class enemies and were deported or killed. Peasants slaughtered livestock rather than hand it over. Grain requisitioning continued even as harvests fell, producing the famine of 1932–33, which killed millions, especially in Ukraine and Kazakhstan. By the late 1930s almost all farms were collectivised and the state controlled the grain supply, but agriculture remained inefficient.

Why did Stalin purge the party, army and people?

The murder of the Leningrad party leader Kirov in December 1934 was used to justify mass arrests. The Moscow Show Trials (1936–38) saw old Bolsheviks — Zinoviev, Kamenev and later Bukharin — confess to invented crimes and be executed. Under Yezhov, head of the NKVD from 1936 to 1938, the Great Terror reached its height; hundreds of thousands were shot in 1937–38 and many more sent to the gulags, labour camps where prisoners worked in brutal conditions. The armed forces were purged too: Marshal Tukhachevsky was executed in 1937, along with a large share of senior officers. The purges removed possible rivals and created fear, but they damaged the economy and weakened the army before the war.

The cult of personality presented Stalin as the wise “father of the peoples” through portraits, statues, songs and place names. Censorship and socialist realism required art and literature to glorify Soviet achievement, and history was rewritten — for example, in the Short Course history of the party (1938) — to exaggerate Stalin’s role and erase his enemies.

What was life like in the USSR, 1924–41?

In the towns, workers faced overcrowded housing, food shortages and strict discipline, though the regime offered free education, healthcare and opportunities for promotion. In the countryside collectivisation brought famine and hardship. Party officials and skilled workers enjoyed privileges. Women gained new opportunities in education and work, but in 1936 abortion was banned and divorce made harder as the regime promoted the family. Education expanded and literacy rose, with lessons stressing loyalty to Stalin. Ethnic minorities were persecuted: whole peoples, such as Soviet Koreans in 1937, were deported, and national cultures were suppressed.

How did the USSR survive and win the Second World War?

Germany invaded on 22 June 1941 (Operation Barbarossa). Setbacks in 1941–42 were caused by surprise, the effects of the military purges and Stalin’s refusal to believe warnings. The USSR survived because Moscow held in December 1941, factories were moved east of the Urals, war production soared, Lend-Lease aid arrived from the Allies, and the population endured huge losses. Stalingrad (August 1942–February 1943) ended in the surrender of the German Sixth Army and was the turning point. Soviet forces reached Berlin in 1945. About 27 million Soviet citizens died.

After the war the Fourth Five-year Plan (1946–50) rebuilt heavy industry. Stalin’s prestige as the victor was at its height, yet repression returned: returning prisoners of war were sent to camps, the Leningrad Affair purged officials, and the “Doctors’ Plot” (1953) targeted mainly Jewish doctors. When Stalin died in March 1953, the USSR was a nuclear superpower controlling Eastern Europe, but its people were poor and many lived in fear.

Frequently asked questions

Was Stalin’s success in 1924–29 down to Trotsky’s weaknesses? Partly. A strong answer weighs Trotsky’s mistakes against Stalin’s control of the party machine and his tactics.

Were the Five-year Plans a success? For heavy industry, largely yes; for living standards and consumer goods, no. Say which criterion you are using.

What is the difference between the NKVD and the gulag? The NKVD was the secret police; the gulag was the system of labour camps it ran.
