IB History (2028+) — Why did authoritarian rule emerge?

Topic 8.1 of IB History (first exams 2028) covers Why did authoritarian rule emerge?, which is part of Unit 8: Paper 2 · Authoritarian rule (from 1750 CE). Students explore key concepts including Why authoritarian rule emerged. A strong understanding of why did authoritarian rule emerge? is essential for IB History (2028+) exams and builds the foundation for connected topics across the syllabus.

Key concepts in Why did authoritarian rule emerge?

Key Idea: Nobody hands over their freedom overnight. Authoritarian rule — power concentrated in one person or one party — usually creeps in step by step, and it is never caused by just one thing.

Historians look for a recipe of four ingredients that combine together: ideas (an ideology that justifies concentrated power), social factors (a frightened or divided population), conflict (war, revolution, civil war), and economic factors (depression, hyperinflation, poverty).

This topic tests that recipe using two contrasting case studies — Nazi Germany in Europe and Mao's China in Asia — so you can compare how the same ingredients combine in very different ways.


How this topic is tested (Paper 2)

Paper 2 questions are thematic and cross-regional. Section A asks for a mini-essay on a concept like cause and consequence [6 marks]. Section B(a) asks you to explain one factor or example [4 marks]. Section B(b) asks a 'to what extent' essay [15 marks] which MUST use at least two examples from at least two different regions — for this topic, that almost always means pairing Germany (Europe) with China (Asia), and optionally adding Cuba (Americas) as a third example.

The examiner is not just checking facts — they want a clear thesis, precise dates and names as evidence, and a final judgement that directly answers 'to what extent'.


Must-know facts

FactorGermany (Europe)China (Asia)
Ideas / ideologyFascism and ultranationalism — Hitler's Nazi Party blamed the Treaty of Versailles (1919), Jews, communists and the Weimar government for Germany's declineMarxism-Leninism reshaped by Mao Zedong into Mao Zedong Thought — revolution led by peasants, not industrial workers
Social baseThe Mittelstand — small shopkeepers, farmers, clerks — feared poverty and feared communist revolution even moreThe rural peasantry, won over through land redistribution from landlords, starting in the Jiangxi and Yan'an base areas after the Long March (1934-35)
ConflictDefeat in WWI and the humiliating Treaty of Versailles; political violence during the DepressionCivil war between the CCP and the Nationalists (Guomindang) from 1927, deepened by Japan's invasion and occupation (1937-1945)
Economic factorsHyperinflation (1923) then the Wall Street Crash (1929) — unemployment hit about 6 million by 1932War devastation, inflation and Nationalist corruption destroyed the government's credibility
Path to powerLegal and gradual: Nazi vote share rose from 2.6% (1928) to 37.3% (July 1932); Hindenburg appointed Hitler Chancellor (Jan 1933); the Enabling Act (March 1933) let him rule by decreeMilitary victory: the CCP defeated the Nationalists in the civil war, and Mao declared the People's Republic of China on 1 October 1949
  • Cause and consequence — the key concept for this topic: big political change always has multiple, interrelated causes, never one dramatic trigger.
  • A third region for extra range — Cuba (Americas, 1959): Fidel Castro's guerrilla war against Batista combined conflict, poverty and socialist ideology — the same recipe in a new setting.
  • Continuity and change — old elites (German industrialists, Chinese landlords) sometimes survived even as the political system was transformed completely.

Important: Do not write about only ONE region. A §B(b) essay that stays entirely inside Germany, however detailed, cannot reach the top markband — you MUST bring in a second region (China, or a third like Cuba) and actively compare, not just describe each in turn.

What four factors does the 'recipe' for authoritarian rule include? Ideas (ideology), social factors, conflict, and economic factors — usually combining together rather than acting alone.

What economic shock hit Germany in 1929, and what was the result by 1932? The Wall Street Crash. Unemployment reached about 6 million, and Nazi support jumped from 2.6% of the vote (1928) to 37.3% (July 1932).

How did Hitler legally become Chancellor, and what let him rule by decree? President Hindenburg appointed him Chancellor in January 1933; the Enabling Act of March 1933 then gave him the power to rule by decree.

What was the Long March, and why did it matter for the CCP? A gruelling retreat (1934-35) to the Yan'an base area. It let the CCP survive and kept building peasant loyalty through land redistribution.

What role did Japan's invasion play in the Chinese Communist Party's rise? Japan's invasion and occupation (1937-1945) devastated the Nationalists' credibility and resources far more than the Communists', clearing the CCP's path to victory in 1949.

Name the key concept this topic keeps testing. Cause and consequence — the idea that major political change always results from multiple, interacting causes, not a single trigger.

Always pair Germany with China (add Cuba for extra range). Use precise dates and figures as evidence (1929, 1932, 1937, 1945, 1949). Structure your §B(b) essay by factor or by region, but always end with a direct judgement on 'to what extent'.
