Why authoritarian rule emerged (History (2028+) HL)

Nobody wakes up one morning and hands over all their freedom. Authoritarian rule — power concentrated in one group or one person — usually arrives step by step, and almost never for just one reason.

Historians studying this thematic study look for four ingredients that tend to combine: ideas, social conditions, conflict, and economic crisis. This micro-topic is about spotting that mix in real regimes.

Cause and consequence in action: The concept of cause and consequence reminds us that big political changes have multiple, interrelated causes working together — never one dramatic trigger alone. A crisis creates the opening; an ideology and a social base decide who walks through it.

On their own, each factor is rarely enough. It is the combination — and the timing — that lets a small group or one person seize and hold power.

Germany in the 1920s is the textbook case of crisis feeding extremism. The Treaty of Versailles (1919) had forced Germany to accept blame for the First World War, pay huge reparations, and lose territory.

That humiliation never went away. Adolf Hitler's Nazi Party built an ultranationalist ideology around reversing it — restoring German pride, rejecting the 'stab in the back' myth, and blaming Jews, communists and the Weimar government for national decline.

The economic trigger: When the Wall Street Crash (1929) hit, Germany's fragile economy — already weakened by hyperinflation in 1923 — collapsed again. Unemployment reached around 6 million by 1932. Nazi support jumped from 2.6% of the vote in 1928 to 37.3% in July 1932 — the Depression turned a fringe party into the largest in the Reichstag.

Socially, it was the Mittelstand — small shopkeepers, farmers, clerks — who felt most exposed. They feared sliding into poverty and feared communist revolution even more. The Nazis offered them order, national pride, and someone else to blame.

China's path to Communist rule looks very different on the surface, but the same ingredients are there — just arranged differently.

From 1927, the Chinese Communist Party (CCP) fought a long civil war against the Nationalist government (the Guomindang). That conflict was interrupted, but also deepened, by Japan's brutal invasion and occupation of China from 1937 to 1945, which devastated the Nationalists' credibility and resources far more than the Communists'.

Building a mass base: While the Nationalists governed cities, the CCP retreated to rural base areas — first Jiangxi, then Yan'an after the gruelling Long March (1934–35). There, Mao Zedong's forces redistributed land from landlords to peasants, winning deep loyalty from China's overwhelmingly rural population.

The ideology behind this was Marxism-Leninism, reshaped by Mao into what became known as Mao Zedong Thought — a claim that revolution could be led by peasants, not just industrial workers, fitting China's mostly agricultural society.

By 1949, the Nationalist government had collapsed under the weight of war, inflation and corruption. Mao declared the People's Republic of China on 1 October 1949 — a civil-war victory, not an election.
