Governance — A variety of internal and external factors contribute to state formation, expansion, and decline. Governments maintain order through a variety of administrative institutions, policies, and procedures, and governments obtain, retain, and exercise power in different ways and for different purposes.

Unit 7.A
Explain how internal and external factors contributed to change in various states after 1900.

  • KC-6.2.I The West dominated the global political order at the beginning of the 20th century, but both land-based and maritime empires gave way to new states by the century’s end.
  • KC-6.2.I.A The older, land-based Ottoman, Russian, and Qing empires collapsed due to a combination of internal and external factors. These changes in Russia eventually led to communist revolution.
  • KC-6.2.II.D States around the world challenged the existing political and social order, including the Mexican Revolution that arose as a result of political crisis.

Unit 7 covers global conflict from 1900, and its organising question is not "what happened in the wars" but why the political order that existed in 1900 collapsed, and what replaced it.

At the start of the century the West dominated the global political order. Over the following decades both land-based and maritime empires gave way to new states, and the CED names the mechanism as a combination of internal and external factors 内外因素.

  • The older land-based Ottoman, Russian, and Qing empires collapsed under that combination - internal strain and pressure from outside at the same time.
  • States around the world challenged the existing political and social order, and the CED's named case is the Mexican Revolution 墨西哥革命, which arose from political and economic inequality.

The examinable habit here is pairing. An answer that gives only internal weakness, or only external pressure, has given half the explanation.

Unit 7.B
Explain the causes and consequences of World War I.

  • KC-6.2.IV.B.i The causes of World War I included imperialist expansion and competition for resources. In addition, territorial and regional conflicts combined with a flawed alliance system and intense nationalism to escalate the tensions into global conflict.

Source: College Board AP Course and Exam Description

The CED compresses the causes into one statement, and every element of it is worth marks:

  • Imperialist expansion 帝国主义扩张 and competition for resources 资源竞争.
  • Territorial and regional conflicts 领土与地区冲突.
  • A flawed alliance system 结盟体系 that turned a local conflict into a general one.
  • Intense nationalism 极端民族主义.

Notice the shape of the claim: imperial rivalry, regional conflict and nationalism increased tension, while alliances, mobilisation plans and leaders’ choices contributed to escalation 升级. That distinction - between what made conflict likely and what made it global - is the single most useful thing to hold from this topic.

Unit 7.C
Explain how governments used a variety of methods to conduct war.

  • KC-6.2.IV.A.i World War I was the first total war. Governments used a variety of strategies, including political propaganda, art, media, and intensified forms of nationalism, to mobilize populations (both in the home countries and the colonies) for the purpose of waging war.
  • KC-6.1.III.C.i New military technology led to increased levels of wartime casualties.

Total war: what a government must control once war stops being a matter for armies alone
The same four instruments appear in both wars, which is why the comparison question is answerable

World War I was a total war 总体战 on a global scale. Earlier conflicts, including the American Civil War, had already mobilised societies extensively; calling it the first total war is misleading. The CED lists the methods governments used, and they are not only military:

  • Political propaganda 政治宣传, art, and media to sustain public support.
  • Intensified forms of nationalism 强化的民族主义.
  • Mobilisation of economies and populations 经济与人口动员 - conscription, war production, and the direction of labour.
  • Recruitment and use of colonial subjects 殖民地臣民 as soldiers and labourers.

Alongside this, new military technology led to increased levels of wartime casualties. The technological point and the mobilisation point are separate marks, so give both.

Unit 7.D
Explain how different governments responded to economic crisis after 1900.

  • KC-6.3.I.B Following World War I and the onset of the Great Depression, governments began to take a more active role in economic life.
  • KC-6.3.I.A.i In the Soviet Union, the government controlled the national economy through the Five Year Plans, often implementing repressive policies, with negative repercussions for the population.

Illustrative examples:

  • Government intervention in the economy:
    • The New Deal
    • The fascist corporatist economy
    • Governments with strong popular support in Brazil and Mexico

Source: College Board AP Course and Exam Description

Following World War I and the onset of the Great Depression 大萧条, governments began to take a more active role in economic life. That is the general claim; the CED then supplies contrasting cases of how far that role went.

In the Soviet Union 苏联, the government controlled the national economy through the Five Year Plans 五年计划, implementing repressive policies at significant cost to the population 人口代价 while achieving rapid industrialisation.

The general pattern that makes this comparable across cases: economic crisis encouraged greater state intervention in many economies, but the extent 程度 differed enormously - from regulation and public works at one end to full state control at the other. Questions about the interwar economy almost always reward that spectrum.

Unit 7.E
Explain the continuities and changes in territorial holdings from 1900 to the present.

  • KC-6.2.I.B Between the two world wars, Western and Japanese imperial states predominantly maintained control over colonial holdings; in some cases, they gained additional territories through conquest or treaty settlement and in other cases faced anti-imperial resistance.

Illustrative examples:

  • Territorial gains:
    • Transfer of former German colonies to Great Britain and France under the system of League of Nations mandates
    • Manchukuo/Greater East Asia Co-Prosperity Sphere
  • Anti-imperial resistance:
    • Indian National Congress
    • West African resistance (strikes/congresses) to French rule

Source: College Board AP Course and Exam Description

Between the two world wars, Western and Japanese imperial states predominantly maintained control over colonial holdings, and in some cases gained new territory. The hopes for self-determination 民族自决 raised by the peace settlement were largely not met for colonised peoples.

This is the bridge topic: the tensions the settlement left unresolved feed directly into both the causes of the next war and the anti-imperial movements of Unit 8. Naming that link is what makes a continuity answer strong.

Unit 7.F
Explain the causes and consequences of World War II.

  • KC-6.2.IV.B.ii The causes of World War II included the unsustainable peace settlement after World War I, the global economic crisis engendered by the Great Depression, continued imperialist aspirations, and especially the rise to power of fascist and totalitarian regimes that resulted in the aggressive militarism of Nazi Germany under Adolf Hitler.

Source: College Board AP Course and Exam Description

The CED again gives a compound cause, and each element is examinable:

  • The unsustainable peace settlement 和约 after World War I.
  • The global economic crisis 全球经济危机 produced by the Great Depression.
  • Continued imperialist practices 帝国主义行径.
  • The rise of fascism and extreme nationalism.

Compare this with the World War I list and a real pattern appears: economic pressure and nationalism are common to both, while the specific additions in 1939 are the failed settlement and the new ideological regimes. A comparison question wants exactly that structure - shared causes named, then the differences.

Unit 7.G
Explain similarities and differences in how governments used a variety of methods to conduct war.

  • KC-6.2.IV.A.ii World War II was a total war. Governments used a variety of strategies, including political propaganda, art, media, and intensified forms of nationalism, to mobilize populations (both in the home countries and the colonies or former colonies) for the purpose of waging war. Governments used ideologies, including fascism and communism to mobilize all of their state’s resources for war and, in the case of totalitarian states, to repress basic freedoms and dominate many aspects of daily life during the course of the conflicts and beyond.
  • KC-6.1.III.C.ii New military technology and new tactics, including the atomic bomb, fire-bombing, and the waging of “total war” led to increased levels of wartime casualties.

Illustrative examples:

  • Western democracies mobilizing for war:
    • Great Britain under Winston Churchill
    • United States under Franklin Roosevelt
  • Totalitarian states mobilizing for war:
    • Germany under Adolf Hitler
    • USSR under Joseph Stalin

Source: College Board AP Course and Exam Description

World War II was also a total war, and governments used the same broad categories of method: propaganda, art and media, intensified nationalism, and the mobilisation of economies and populations including colonial subjects.

What changed was the technology and its scale. New military technology and new tactics - including the atomic bomb 原子弹, fire-bombing, and the waging of total war - led to increased levels of casualties, including a far higher proportion of civilian 平民 deaths than in the previous conflict.

The examinable comparison is therefore: methods largely similar, scale and technology different. An answer that says only "both were total wars" has not compared them; an answer that says only "the second was more destructive" has not explained why.

Unit 7.H
Explain the various causes and consequences of mass atrocities in the period from 1900 to the present.

  • KC-6.2.III.C The rise of extremist groups in power led to the attempted destruction of specific populations, notably the Nazi killing of the Jews in the Holocaust during World War II, and to other atrocities, acts of genocide, or ethnic violence.

Illustrative examples:

  • Genocide, ethnic violence, or attempted destruction of specific populations:
    • Armenians in the Ottoman Empire during and after World War I
    • Cambodia during the late 1970s
    • Tutsi in Rwanda in the 1990s
    • Ukraine in the Soviet Union in the 1920s and 1930s

Source: College Board AP Course and Exam Description

This topic asks for causes and consequences of mass atrocities in the period from 1900 to the present. The CED's framing is that the rise of extremist groups in power 极端主义团体 led to the attempted destruction of specific populations, and it names the Holocaust 犹太人大屠杀 - the Nazi killing of Jewish people - as the principal case, alongside other twentieth-century genocides and mass killings.

Handled as history, the examinable content is the pattern: an extremist regime takes state power, defines a population as outside the political community, and uses the machinery of the modern state - bureaucracy, transport, communication - to carry out destruction with greatly increased capacity to coordinate persecution and killing. That last point connects this topic to the technology theme running through the whole unit.

Unit 7.I
Explain the relative significance of the causes of global conflict in the period 1900 to the present.

  • KC-6.1 Rapid advances in science and technology altered the understanding of the universe and the natural world and led to advances in communication, transportation, industry, agriculture, and medicine.
  • KC-6.2 Peoples and states around the world challenged the existing political and social order in varying ways, leading to unprecedented worldwide conflicts.
    • KC-6.2.I The West dominated the global political order at the beginning of the 20th century, but both land-based and maritime empires gave way to new states by the century’s end.
    • KC-6.2.I.A The older, land-based Ottoman, Russian, and Qing empires collapsed due to a combination of internal and external factors. These changes in Russia eventually led to communist revolution.
    • KC-6.2.II.D States around the world challenged the existing political and social order, including the Mexican Revolution that arose as a result of political crisis.

The unit's reasoning skill is causation, and specifically the relative significance 相对重要性 of causes. That word "relative" is the whole task: you are not listing causes, you are ranking them and defending the ranking.

Original worked comparison. For original short-answer practice, try "Explain one similarity between the ways governments conducted World War I and World War II." An illustrative answer names the similarity and supports it with specifics from both: "Both wars were total wars in which governments mobilised entire economies and populations. In both, states used propaganda and media to sustain public support, directed industrial production toward war material, and recruited soldiers and labourers from their colonies." Notice the requirement: a similarity claim must be evidenced on both sides. Evidence from one war only cannot demonstrate a similarity.

Worked example: a short-answer question

Each part needs only one or two sentences: answer the question, cite one specific piece of evidence, and explain how it supports the answer.

Answer (a), (b) and (c).

(a) Briefly describe ONE cause of the First World War.

(b) Briefly explain ONE way governments conducted 'total war'.

(c) Briefly explain ONE political effect of the Great Depression.

Model answer.

  • (a) The alliance system meant that the assassination of Archduke Franz Ferdinand in 1914 drew several great powers into one war.
  • (b) Governments used conscription and propaganda, and moved women into factory work, so whole societies were mobilised.
  • (c) Economic crisis increased support for extreme parties; in Germany the Nazi Party grew rapidly in elections between 1930 and 1932.

Exam tips

  • For the collapse of the Ottoman, Russian, and Qing empires, always pair internal strain with external pressure. One alone is half an answer.
  • Explain how imperial competition, nationalism, regional conflict, alliances and mobilisation decisions interacted; alliances alone did not automatically cause a global war.
  • Total war has a checklist: propaganda, nationalism, economic mobilisation, colonial recruitment. Use it for both wars and the comparison writes itself.
  • The interwar economy is a spectrum of state involvement, not a single policy. Say how far a state went, not just that it intervened.
  • Comparison questions need evidence on both sides. A detail about only one case cannot support a similarity or a difference.
  • "Relative significance" means rank and justify. A list of causes with no argument about which mattered most does not answer the question asked.
