Every term in Unit 6
All 37 terms we publish for Consequences of Industrialization, with definitions. Reading them through is the fastest way to find the ones you cannot define — then drill those in cram mode until you can produce them without the prompt.
- New imperialism
- Late nineteenth-century European conquest of Africa and Asia, driven by raw materials, markets, strategic rivalry and racial ideology.
- Indentured labor migration
- Multi-year contract labor drawing millions of Indian and Chinese workers to plantations and mines in Trinidad, Mauritius, Natal, Fiji, and the Americas. Significance: replaced enslaved labor after abolition, reproducing coercion in legal form and creating large Asian diasporas.
- Berlin Conference (1884–85)
- European powers partitioned Africa among themselves without African representation, drawing borders that ignored existing polities.
- Scramble for Africa
- Within two decades almost the whole continent was under European control, enabled by machine guns, quinine and steamships.
- Social Darwinism
- Misapplied evolutionary language to rank societies, supplying a pseudo-scientific justification for conquest and rule.
- White Man's Burden
- Kipling's framing of imperialism as a civilizing duty — the moral cover for economic and strategic motives.
- Economic imperialism
- Control through investment, debt and unequal treaties rather than direct rule, as in Latin America and Qing China.
- Opium Wars
- Britain forced China to accept opium imports; defeat brought unequal treaties, extraterritoriality and Hong Kong.
- Unequal treaties
- Imposed tariffs, ports and legal exemptions on China and Japan, exposing the gap between industrial and non-industrial military power.
- Taiping Rebellion
- Massive mid-century Chinese civil war costing perhaps twenty million lives and leaving the Qing dependent on regional armies.
- Meiji Restoration
- Japan's deliberate, state-directed industrialization and reform after 1868 — the one non-Western state to industrialize on its own terms in this period.
- Self-Strengthening Movement
- Qing attempt to adopt Western technology while preserving Confucian institutions. Its failure contrasts sharply with Meiji success.
- Sepoy Rebellion (1857)
- Indian uprising that ended East India Company rule and brought direct British Crown government of India.
- Settler colonies
- Australia, New Zealand, Algeria and South Africa, where European settlement displaced indigenous populations rather than only extracting resources.
- Abolition of slavery
- Britain in 1833, the US in 1865, Brazil in 1888. Driven by moral campaigning, enslaved resistance and industrial economies less dependent on slave labor.
- Four parts of a conquest answer
- Weapons, medicine, transport and communication, and local soldiers and allies. The last is the one students omit and the one that made conquest possible.
- Maxim gun
- Early machine gun producing lethal asymmetry against forces with older firearms, most starkly at Omdurman in 1898.
- Battle of Omdurman (1898)
- Roughly eleven thousand Sudanese killed against about forty-eight British dead — the clearest single illustration of the industrial arms gap.
- Quinine prophylaxis
- Reduced European malaria mortality enough to make African interiors survivable, which is why the timing of the scramble tracks the medicine rather than the ambition.
- Suez Canal (1869)
- Halved the passage between Europe and Asia, and became so strategically vital that control of Egypt followed from control of the canal.
- Telegraph and imperial control
- Let a capital direct a distant campaign in hours instead of months, which made governing remote territory administratively feasible.
- Indirect rule
- Governing through existing local authorities, as with the emirs of northern Nigeria — cheap, and it entrenched the elites and categories that later destabilized successor states.
- Berlin Conference borders
- European powers divided Africa among themselves without African participation, drawing lines that cut through peoples and combined rivals — a decision whose consequences run into Units 8 and 9.
- Menelik II
- Centralized Ethiopian authority and bought modern rifles and artillery from European suppliers happy to arm Italy's rival, then destroyed an Italian army at Adwa in 1896.
- Conditions for successful resistance
- Centralized authority, modern weapons acquired in time, and either favorable terrain or a rival power to court. States lacking all three were conquered.
- Extraterritoriality
- Foreign nationals exempted from local law and tried under their own countries' courts — a direct limitation on sovereignty imposed on China and elsewhere.
- Treaty of Nanjing (1842)
- Ended the first Opium War with indemnities, the cession of Hong Kong, opened treaty ports and fixed tariffs China could not change.
- What the Opium Wars were about
- Britain's claim to sell in China a drug the Chinese state had banned, enforced by naval superiority. Stating it precisely is what distinguishes a strong answer.
- Spheres of influence
- Zones where a foreign power held exclusive commercial and investment privileges without formal annexation — control of terms without the cost of governing.
- Ottoman Public Debt Administration
- European creditors effectively controlling Ottoman finances, the clearest case of debt functioning as an instrument of imperial power.
- Cash-crop monoculture
- Regions pushed into single export crops by taxes payable only in cash, producing vulnerability to world prices and reduced local food production.
- Colonial railways ran to ports
- Rail networks connected extraction zones to harbors rather than towns to each other. Infrastructure built for extraction is evidence of imperialism, not development.
- Colonial famine as policy
- Cash-crop conversion removed food reserves, traditional relief was dismantled, and free-market doctrine discouraged intervention while grain was exported. Drought became mass mortality.
- Congo Free State
- Leopold II's rubber regime enforced by mutilation and killing, ended when international protest forced Belgium to annex the territory from him in 1908.
- J. A. Hobson
- Argued in Imperialism: A Study that empire served narrow financial interests while ordinary taxpayers paid, an argument Lenin later adapted.
- Mission civilisatrice
- The civilizing mission: domination framed as a duty owed to peoples represented as children, which made conquest appear generous.
- Scientific racism
- Skull measurement, racial taxonomies and eugenics dressing hierarchy as biological fact — distinct from Social Darwinism, which made a claim about competition rather than biology.
What examiners penalize here
- Explain imperialism through the *industrial* lens: factories needed raw materials and markets, and industrial *technology* (steamships, railroads, machine guns, quinine) made conquest feasible. Tying imperialism back to industrialization is exactly the causal link this unit tests.
- Always include **local allies and indigenous soldiers** in a conquest answer. It is the element most often left out, it is decisive, and it protects you from the mistaken picture of small European armies defeating whole societies unaided.
Practice World History
Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
Questions about this unit
How much of the AP World History: Modern exam is Unit 6?
Unit 6, Consequences of Industrialization, is worth 12–15% of the World History multiple-choice section according to the published course framework. Across all 9 units that makes it a substantial share — heavier than an even split would give it.
What topics are covered in World History Unit 6?
Consequences of Industrialization covers Imperialism, Global economy, Migration and Resistance. We publish 37 terms with definitions for this unit, all of them on this page.
How should I study World History Unit 6?
Read the 6 lessons below first — about 85 minutes — then drill the 37 terms in cram mode until you can produce each definition from memory rather than just recognize it. Recognition is what makes a unit feel finished when it is not. Finish with practice questions and read the explanation for every one you get right by elimination as well as the ones you miss.
