Successes and failures to weigh

Policy Successes Failures
Five-year Plans Rapid growth of coal, steel, electricity; new industrial cities; base for war production Poor quality, waste, few consumer goods, harsh discipline, forced labour
Collectivisation State control of grain; mechanisation; funds and labour for industry Famine of 1932–33; loss of livestock; kulaks destroyed; low productivity
Purges Removed rivals; total obedience Lost experts and officers; fear; weakened army in 1941

Worked example: two effects

Explain two effects of the purges on the Soviet Union.

  1. Weakened armed forces: Tukhachevsky and many senior officers were executed in 1937–38, so the Red Army lacked experienced commanders — one reason for the disasters of 1941.
  2. Fear and obedience: mass arrests by the NKVD meant no one dared to criticise Stalin, giving him unchallenged power but discouraging initiative in the economy.

Essay plan in outline

“Stalin’s control of the party machine was the main reason he became leader by 1929.” How far do you agree?

  • Paragraph 1 (stated factor): as General Secretary he appointed loyal officials who voted at party congresses; the “Lenin Enrolment” brought in new members grateful to him.
  • Paragraph 2 (other factors): alliance tactics — first with Zinoviev and Kamenev against Trotsky, then with Bukharin against them, then against Bukharin himself.
  • Paragraph 3 (rivals’ weaknesses): Trotsky’s arrogance, his absence from Lenin’s funeral and the suppression of Lenin’s Testament.
  • Conclusion: the party machine gave Stalin the votes; tactics decided when to use them.

Common mistakes and exam traps

  • Dating collectivisation. The specification refers to collectivisation from 1928; the main drive began in late 1929. Avoid saying it began in 1932.
  • Mixing up the factions. Zinoviev and Kamenev were the Left with Trotsky (by 1926); Bukharin led the Right.
  • Treating the purges as one event. Separate the party (show trials), the army and the general population.
  • Only negative judgements. Essays on the Plans must weigh real industrial growth against the human cost.
  • Ignoring the post-war years. Key topic 5 runs to 1953; know the Fourth Plan and post-war purges.

Frequently asked questions

Why was Kirov’s murder significant? It gave Stalin a pretext for arrests and new laws that led to the show trials and the Great Terror.

Why did the USSR survive 1941? Distance and winter, the defence of Moscow, the evacuation of industry, war production, Allied aid and enormous sacrifices.

What does “the revision of history” mean? Rewriting Soviet history to glorify Stalin and remove his enemies, as in the 1938 Short Course.
