Key concepts in Consolidation and maintenance of power

Key Idea: Winning power is one job; keeping it is another. Authoritarian leaders stayed in charge by mixing four things — law, force, a cult of the leader and propaganda — and by crushing or scaring off anyone who dared to oppose them. In Paper 2 you compare how two states from two different world regions pulled this off.

🏛️ 15.2.1 — The four pillars of control

Once a leader was in office, three problems landed at once: get rid of rivals, take over the machinery of the state, and win over (or frighten) ordinary people. The cleverest regimes never leaned on one trick — they wrapped raw force inside a cloak of legality and a warm glow of public love, so obeying felt both unavoidable and patriotic.

Think of it as four pillars. Law made the dictatorship look legal — Hitler's Enabling Act (March 1933) let him pass laws without parliament. Force ruled through fear, using secret police like the German Gestapo and the Soviet NKVD. A cult of personality painted the leader as a faultless saviour (the Führer cult; Stalin's cult; Mao's Little Red Book). And propaganda flooded people's minds with the regime's version of the truth while censorship hid every rival idea.

  • Law: Reichstag Fire Decree (Feb 1933) suspended basic rights; Enabling Act (Mar 1933) let Hitler rule by decree; Gleichschaltung ('bringing into line') put press, courts and unions under Nazi control — Germany was a one-party state by July 1933.
  • Force: Gestapo (Germany) and NKVD (USSR) spied on and arrested opponents; Stalin's Great Purge/Great Terror (1936–38) used fake show trials and mass executions.
  • Cult of personality: glorifying the leader as an all-wise, faultless hero — the Führer cult, Stalin's cult, and the cult of Mao (peaking in the Cultural Revolution from 1966).
  • Propaganda: Goebbels ran the Nazi Ministry of Propaganda (radio, film, rallies); the USSR used socialist realism art and abolished the free press.
  • Key terms: a totalitarian state tries to control every part of life; a one-party state bans all rival parties, so voters get no real choice.

🕵️ 15.2.2 — Opposition and how regimes crushed it

In most authoritarian states, few people dared to speak out — not because everyone agreed, but because opposing the regime could cost you your freedom or your life. Historians split resistance into active opposition (doing something — secret leaflets, plots, sabotage) and passive opposition (quiet dissent — grumbling at home, refusing to salute or join rallies).

When you study opposition, answer three questions: Who opposed (rivals, churches, youth, minorities, sometimes the army)? How much — usually not much, kept down by fear, propaganda and a divided opposition. And how did the regime hit back? Almost everywhere the answer was repression and terror, aimed both at destroying real opponents and at frightening everyone else into silence.

  • Regime tools spell SCRAP: Surveillance, Camps, Repression/terror, Arrests and executions, Purges and show trials.
  • Camps: Nazi Dachau (opened 1933 for political prisoners); the Soviet Gulag forced-labour network held millions.
  • USSR terror: the Great Terror (1936–38), the Moscow show trials of old leaders (Zinoviev, Kamenev, Bukharin), and a purge of most senior army officers.
  • Germany: the Night of the Long Knives (30 June 1934) murdered SA leaders and rivals; the White Rose student group was crushed.
  • A different region — Mao's China (Asia): the Anti-Rightist Campaign (1957) and the Cultural Revolution (1966–76) used mass campaigns and Red Guards to attack 'enemies'.

🎯 One-glance recall

The four pillars of control Law (Enabling Act 1933, Germany), force (Gestapo, NKVD, purges), a cult of personality (Führer cult, Stalin, Mao), and propaganda (Goebbels' ministry, socialist realism). Force compels people; the cult and propaganda persuade them.

How opposition was crushed (SCRAP) Surveillance, Camps, Repression/terror, Arrests and executions, Purges and show trials. The aim was double: destroy real opponents and frighten everyone else into silence. Key events: Night of the Long Knives (30 June 1934) and Stalin's Great Terror (1936–38).

Two regions rule Paper 2 needs two states from two different IB regions (Europe; Africa and the Middle East; the Americas; Asia and Oceania). Hitler (Europe) + Mao (Asia) is valid; Hitler + Stalin is NOT, because both are Europe.

How to score marks Structure by THEME, not state by state. Use precise evidence (dates, laws, secret police, events). For 'to what extent' / 'evaluate', keep weighing effectiveness and end with a judged verdict — narrative alone does not score.
