20th-Century Global Conflicts, c. 1914 to present

Unit 8 covers c. 1914 to the present as a story of conflict, and four key concepts frame it:

• Total war 总体战 and political instability 政治动荡 in the first half of the century gave way to a polarised state order during the Cold War 冷战.
• The stresses of economic collapse and total war produced internal conflicts within European states and conflicting conceptions of the relationship between the individual and the state.
• Diverse intellectual and cultural movements questioned the existence of objective knowledge 客观知识 and the authority that had rested on it.
• Demographic change, economic growth, total war, and competing definitions of freedom and justice altered the experience of everyday life.

The war was caused by a complex interaction of long- and short-term factors and produced immense losses and disruption. The CED's specific claims:

• New technologies confounded traditional military strategies, leading to trench warfare 堑壕战 and massive troop losses.
• The effects of military stalemate 僵局, national mobilisation 动员, and total war led to protest 抗议 and insurrection 起义 in the belligerent 交战的 nations - the war turned inward on the societies fighting it.
• The war spread quickly to non-European theatres 战场, becoming a global conflict.
• The relationship of Europe to the world shifted significantly with that globalisation, and with the emergence of new powers.

The Russian Revolution 俄国革命 created a regime based on Marxist-Leninist theory 马克思列宁主义 - the first state to be founded explicitly on that programme, which is what makes it a turning point rather than a national event.

The conflicting goals of the peace negotiators in Paris pitted diplomatic idealism 理想主义 against the desire to punish Germany, and the resulting settlement satisfied neither aim fully.

The League of Nations 国际联盟 distributed former German and Ottoman possessions to powers including France, Great Britain, Japan and Belgium, as well as British dominions, through the mandate system 委任统治, which extended imperial control under a new name - a point worth making because it connects the settlement to decolonisation later in the course.

The Great Depression 大萧条, caused by weaknesses in international trade and in monetary theory and practice, undermined Western European democracies 民主国家 and fostered radical political responses across Europe.

This is the pivot of the unit. The Depression enlarged the political opportunity for movements such as Nazism in Germany. It cannot explain every fascist accession: Mussolini had become Italian prime minister in 1922, before the Depression began.

The ideology of fascism 法西斯主义, with roots in the pre-war era, gained popularity in an environment of postwar bitterness, the rise of communism, uncertain transitions to democracy, and economic instability. That four-part environment is the CED's own answer to "why then", and it is better than any single cause.

On the Soviet side, after Lenin's death Stalin 斯大林 undertook a centralised programme of rapid economic modernisation 现代化, often with severe repression 镇压. The CED states the cost explicitly: modernisation came at a high price, including the liquidation of the kulaks 富农 and a catastrophic famine 饥荒.

The comparison the unit invites is structural rather than ideological: both regimes claimed total authority over the relationship between individual and state, which is the second key concept doing its work.

The failure to prevent a second war has named causes:

• French and British fears of another war, American isolationism 孤立主义, and deep distrust between Western democratic, capitalist nations and the Soviet communist regime prevented an effective response.
• Fascism, extreme nationalism, racist ideologies, and the failure of appeasement 绥靖政策 resulted in the Second World War.

• Germany's Blitzkrieg 闪电战 warfare in Europe, combined with Japan's attacks in Asia and the Pacific, brought the Axis powers 轴心国 early victories.
• American and British industrial, scientific, and technological power, cooperative military efforts under strong leadership, and the Soviet Union's vast manpower and resources eventually defeated the Axis.
• Military technologies made possible industrialised warfare, genocide 种族灭绝, nuclear proliferation 核扩散, and the risk of global nuclear war.

Fuelled by racism 种族主义 and anti-Semitism 反犹主义, Nazi Germany - with the cooperation of some other Axis powers and collaborators 合作者 - used industrial technology and bureaucratic structures to carry out the systematic murder of European Jewish people and other targeted groups.

The CED's framing is precise and should be reproduced: what distinguishes this from earlier mass violence is the use of the modern state's own instruments - industry, bureaucracy, transport, record-keeping - as the means. That is why this topic belongs with the technology and total-war themes rather than standing apart from them.

The demographic consequence is stated directly: the Second World War decimated a generation of Russian and German men, virtually destroyed European Jewry, and killed millions of others.

• The belief in progress characteristic of much nineteenth-century thought began to break down before World War I and collapsed after it.
• When the war began, Europeans were generally confident in the ability of science and technology to address human needs; the war and then the Depression undermined that confidence.
• The challenge to the certainties of the Newtonian universe in physics opened the door to uncertainty in other fields.
• The war created a "lost generation" 迷惘的一代 and fostered disillusionment 幻灭 and cynicism 犬儒主义.
• During both wars, women became increasingly involved in military and political mobilisation and in economic production.

The unit's reasoning skill is continuity and change.

Original worked example. For original short-answer practice, try "Explain one way in which the peace settlement of 1919 contributed to political instability in Europe in the 1920s and 1930s." An illustrative answer traces a mechanism: "The settlement combined punitive terms against Germany with an appeal to national self-determination it could not deliver consistently. That left a German republic burdened with reparations and blamed for accepting them, which gave nationalist and fascist movements a grievance they could use, and which the economic collapse of 1929 turned into mass support." Notice that the answer runs the chain forward to the point the question asks about.

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 effect of the Russian Revolution on the First World War.

(c) Briefly explain ONE cause of the Second World War.

Model answer.

• (a) Militarism and an arms race, especially the Anglo-German naval race, increased tension and readiness for war.
• (b) The Bolsheviks took Russia out of the war with the Treaty of Brest-Litovsk (1918), freeing German troops for the Western Front.
• (c) Resentment of the Treaty of Versailles, and Britain and France's policy of appeasement, including the Munich Agreement (1938), encouraged Hitler's expansion.

• Learn the chain: war, settlement, economic collapse, radical movements, failed appeasement, war again. Most questions ask about one link.
• The CED gives fascism a four-part environment - postwar bitterness, fear of communism, unstable democracies, economic instability. Use all four.
• The Depression helped Nazism gain support, but do not apply that chronology to Mussolini's accession in 1922.
• On the Holocaust, the examinable point is the use of the modern state's own instruments. State it precisely.
• The mandate system is imperial control renamed. Saying so links the settlement to decolonisation.
• The collapse of confidence in progress and objectivity connects the political and cultural halves of the unit. Examiners reward that connection.
