剑桥 IGCSE 历史课程（0470）通过一系列关键问题考察二十世纪的国际关系。本文为选项 B 核心内容“二十世纪：1919 年以来的国际关系”提供了一个清晰而有条理的概述，涵盖一战后的和平条约、国际联盟、通向二战之路、冷战及其后续。掌握这些基础主题将帮助你构建一个世纪关键事件的清晰的叙事框架，并理解塑造现代世界的力量。
1. The Peace Treaties after WWI | 一战后和平条约
The Paris Peace Conference of 1919–20 set out to reshape Europe and the wider world after the devastation of the First World War. The ‘Big Three’ – Georges Clemenceau of France, David Lloyd George of Britain and Woodrow Wilson of the USA – held conflicting aims, which resulted in a series of compromises that left many dissatisfied.
1919–20 年的巴黎和会旨在第一次世界大战的破坏后重塑欧洲和更广阔的世界。“三巨头”——法国的乔治·克列孟梭、英国的大卫·劳合·乔治和美国的伍德罗·威尔逊——持有相互冲突的目标，导致了一系列妥协，使许多方面感到不满。
The Treaty of Versailles, signed with Germany in June 1919, was the most controversial. Germany lost 13% of its European territory, including Alsace-Lorraine to France and the Polish Corridor to newly independent Poland. Its army was restricted to 100 000 men, its navy dramatically reduced, and it was forbidden to possess tanks, military aircraft or submarines. The ‘war guilt clause’ (Article 231) forced Germany to accept full responsibility for the war, and it was required to pay reparations eventually set at 6.6 billion pounds.
1919 年 6 月与德国签订的《凡尔赛条约》最具争议。德国丧失了其欧洲领土的 13%，包括割让给法国的阿尔萨斯-洛林和交给新独立的波兰的波兰走廊。其陆军被限制为十万人，海军大幅削减，并被禁止拥有坦克、军用飞机或潜艇。“战争罪责条款”（第 231 条）迫使德国承担战争的完全责任，并要求其支付最终定为 66 亿英镑的赔款。
Other treaties dealt with Germany’s allies: the Treaty of St Germain with Austria, the Treaty of Trianon with Hungary, the Treaty of Neuilly with Bulgaria and the Treaty of Sèvres (later revised at Lausanne) with Turkey. These settlements broke up the Austro-Hungarian and Ottoman Empires, creating new nation-states such as Czechoslovakia and Yugoslavia. Many Germans felt the peace was a ‘Diktat’ (dictated peace) and deeply resented its terms, a factor that would later be exploited by extremist political movements.
其他条约处理了德国的盟国：与奥地利的《圣日耳曼条约》、与匈牙利的《特里亚农条约》、与保加利亚的《讷伊条约》以及与土耳其的《塞夫尔条约》（后来在洛桑修订）。这些解决方案瓦解了奥匈帝国和奥斯曼帝国，建立了捷克斯洛伐克和南斯拉夫等新的民族国家。许多德国人认为和平是“Diktat”（强加的和平），并对其条款深感怨恨，这一因素后来被极端主义政治运动利用。
2. The League of Nations | 国际联盟
The League of Nations was established in 1920 as part of the Treaty of Versailles, largely inspired by Woodrow Wilson’s Fourteen Points. Its aims were to prevent war through collective security, encourage disarmament and improve living and working conditions globally. In the 1920s, the League enjoyed some successes, such as resolving the Åland Islands dispute between Sweden and Finland (1921) and the Upper Silesia dispute between Germany and Poland (1921). Its health and refugee organizations also did effective humanitarian work.
国际联盟于 1920 年根据《凡尔赛条约》成立，很大程度上受到伍德罗·威尔逊“十四点原则”的启发。其宗旨是通过集体安全防止战争、鼓励裁军并改善全球的生活和工作条件。在 1920 年代，国联取得了一些成功，例如解决了瑞典和芬兰之间的奥兰群岛争端（1921 年）以及德国和波兰之间的上西里西亚争端（1921 年）。其卫生和难民组织也做了有效的人道主义工作。
However, the League was crippled by fundamental structural weaknesses from the start. The USA never joined, despite Wilson’s central role, because the Senate refused to ratify the treaty. Germany was not admitted until 1926, and the USSR joined only in 1934. The League lacked an army of its own and had to rely on member states to enforce its decisions; economic sanctions were its strongest tool but proved difficult to coordinate.
然而，国联从一开始就受到根本性的结构缺陷的制约。尽管威尔逊发挥了核心作用，美国却从未加入，因为参议院拒绝批准该条约。德国直到 1926 年才被接纳，苏联直到 1934 年才加入。国联没有自己的军队，必须依赖成员国来执行其决定；经济制裁是它最有力的工具，但证明难以协调。
The 1930s exposed the League’s impotence. The Manchurian Crisis (1931–33) saw Japan invade Manchuria and set up the puppet state of Manchukuo. The League condemned Japan but took no effective action, and Japan simply walked out in 1933. The Abyssinian Crisis (1935–36) was even more disastrous. Italy, under Mussolini, invaded Abyssinia (Ethiopia). The League imposed limited sanctions but failed to ban oil, and Britain and France continued to allow Italian supplies through the Suez Canal. The League’s failure to protect a member state effectively destroyed its credibility as a peacekeeping body.
1930 年代暴露了国联的无能。满洲危机（1931–33 年）中，日本入侵满洲并建立了傀儡国满洲国。国联谴责日本但未采取有效行动，日本随后于 1933 年退出。阿比西尼亚危机（1935–36 年）更具灾难性。墨索里尼领导下的意大利入侵了阿比西尼亚（埃塞俄比亚）。国联实施了有限制裁，但未能禁止石油，英法继续允许意大利的物资通过苏伊士运河。国联未能保护一个成员国，这实际上摧毁了其作为维和机构的信誉。
3. The Road to World War II | 通向二战之路
During the 1930s, a series of aggressive actions by Germany, Italy and Japan steadily dismantled the post-war order. Hitler’s foreign policy aimed to overturn the Treaty of Versailles, reunite all German-speaking peoples and acquire ‘Lebensraum’ (living space) in the East. His first steps were rearmament (announced 1935), remilitarisation of the Rhineland (1936) and involvement in the Spanish Civil War, all of which met with no effective opposition from Britain or France.
在 1930 年代，德国、意大利和日本的一系列侵略行为逐步瓦解了战后秩序。希特勒的外交政策旨在推翻《凡尔赛条约》，团结所有德语民族，并在东方获取“生存空间”。他的第一步是重整军备（1935 年宣布）、莱茵兰重新军事化（1936 年）和介入西班牙内战，所有这些都没有遭到英法两国的有效反对。
Appeasement became the dominant policy of the Western democracies, driven by a combination of horror at the memory of World War I, economic concerns and a misguided belief that Hitler’s demands were limited and reasonable. The Anschluss with Austria in March 1938 was accepted. The Munich Agreement of September 1938, in which Britain and France agreed to Hitler’s annexation of the Sudetenland from Czechoslovakia, is often seen as the high point of appeasement. Six months later, in March 1939, Hitler seized the rest of Czechoslovakia, demonstrating that his promises could not be trusted.
绥靖政策成为西方民主国家的主导政策，其驱动力来自对一战记忆的恐惧、经济担忧以及一种错误的信念，认为希特勒的要求是有限且合理的。1938 年 3 月与奥地利的“合并”被接受。1938 年 9 月的《慕尼黑协定》——英法同意希特勒从捷克斯洛伐克吞并苏台德地区——常被视为绥靖的顶峰。六个月后，即 1939 年 3 月，希特勒占领了捷克斯洛伐克的其余地区，表明他的承诺不可信任。
The Nazi-Soviet Pact of August 1939 shocked the world. Germany and the USSR secretly agreed to divide Poland between them. This removed Stalin’s potential opposition and gave Hitler the green light for the invasion of Poland on 1 September 1939, which triggered Britain and France’s declaration of war.
1939 年 8 月的《纳粹—苏联条约》震惊了世界。德国和苏联秘密同意划分波兰。这消除了斯大林的潜在反对，为希特勒 1939 年 9 月 1 日入侵波兰开了绿灯，引发了英法宣战。
4. Origins of the Cold War | 冷战的起源
The wartime alliance between the USA, the USSR and Britain rapidly broke down after 1945. Ideological differences between capitalist democracy and communism, which had been temporarily set aside to defeat Hitler, resurfaced. Disagreements over the fate of liberated Eastern Europe, particularly Poland, deepened mistrust. Stalin wanted a buffer zone of friendly communist states as security against future invasion, while the West saw this as Soviet expansionism.
美国、苏联和英国之间的战时同盟在 1945 年后迅速瓦解。为击败希特勒而暂时搁置的资本主义民主与共产主义之间的意识形态分歧重新浮现。在已解放的东欧，特别是波兰的命运问题上的分歧加深了互不信任。斯大林希望有一个由友好的共产主义国家组成的缓冲区作为安全屏障以防未来入侵，而西方则将此视为苏联扩张主义。
Key early flashpoints included the Yalta and Potsdam Conferences (1945), where the Allies agreed on the division of Germany and Berlin into four occupation zones, but papered over deeper splits. The ‘Iron Curtain’ speech by Winston Churchill in 1946 and the Truman Doctrine of 1947, which offered military and economic support to countries threatened by communism, formalised the division. The Marshall Plan provided massive economic aid to rebuild Western Europe, which Stalin interpreted as an attempt to undermine Soviet influence.
关键的早期导火索包括雅尔塔和波茨坦会议（1945 年），盟国在会上同意将德国和柏林划分为四个占领区，但掩盖了更深的裂痕。1946 年温斯顿·丘吉尔的“铁幕”演说，以及 1947 年承诺向受共产主义威胁的国家提供军事和经济支持的特鲁曼主义，使这一分裂正式化。马歇尔计划为重建西欧提供了大量经济援助，斯大林将此解读为企图削弱苏联影响力的行为。
The Berlin Blockade (1948–49) was the first major confrontation. Stalin cut off all land routes to West Berlin in an attempt to force the Western Allies out. The West responded with the Berlin Airlift, supplying the city by air for almost a year. In May 1949 Stalin lifted the blockade, but the crisis cemented the division of Germany, leading to the formal creation of the Federal Republic of Germany (West Germany) and the German Democratic Republic (East Germany) later that year.
柏林封锁（1948–49 年）是第一次重大对抗。斯大林切断了通往西柏林的所有陆路通道，试图迫使西方盟国撤出。西方的回应是柏林空运，为空运供应城市近一年。1949 年 5 月，斯大林解除了封锁，但这场危机巩固了德国的分裂，导致同年晚些时候德意志联邦共和国（西德）和德意志民主共和国（东德）正式成立。
5. USA Containment Policy | 美国的遏制政策
The policy of containment, designed by US diplomat George Kennan, aimed to prevent the further spread of communism by countering Soviet pressure wherever it appeared. This policy was applied in several key regions through the late 1940s and 1950s. The Truman Doctrine (1947) provided military and economic assistance to Greece and Turkey to prevent communist takeovers. The Marshall Plan (1948–52) sought to rebuild Europe’s economies so that poverty would not push voters towards communism.
由美国外交官乔治·凯南设计的遏制政策，旨在通过在苏联压力出现的任何地方予以反击来阻止共产主义的进一步传播。该政策在 1940 年代末和 1950 年代被应用于多个关键地区。特鲁曼主义（1947 年）向希腊和土耳其提供军事和经济援助，以防止共产党夺权。马歇尔计划（1948–52 年）试图重建欧洲经济，以免贫困将选民推向共产主义。
The Korean War (1950–53) was a major test of containment. When communist North Korea invaded South Korea, the USA, acting under a UN resolution (made possible by a Soviet boycott of the Security Council), led a multinational force to repel the invasion. The war ended in a stalemate around the 38th parallel, but it demonstrated America’s willingness to use force to contain communism in Asia. It also led to a massive increase in US defence spending and the rearmament of West Germany.
朝鲜战争（1950–53 年）是遏制政策的一次重大考验。当共产主义朝鲜入侵韩国时，美国根据一项联合国决议（因苏联抵制安理会才得以通过）领导了一支多国部队击退入侵。战争以在三八线附近的僵局告终，但它证明了美国愿意动用武力在亚洲遏制共产主义。这也导致美国国防开支大幅增加和西德重新武装。
Containment also shaped the formation of military alliances. The North Atlantic Treaty Organisation (NATO) was created in 1949 as a collective defence pact; an attack on one member would be considered an attack on all. In response, the USSR formed the Warsaw Pact in 1955. The policy of containment continued to guide US foreign policy through the Cold War, even as later events in Vietnam exposed its limitations.
遏制政策也塑造了军事同盟的组建。北大西洋公约组织（NATO）于 1949 年作为集体防御条约成立；对一个成员国的攻击将被视为对所有成员国的攻击。作为回应，苏联于 1955 年组建了华约组织。遏制政策在整个冷战中继续指导着美国的外交政策，即使后来在越南的事件暴露了它的局限性。
6. Soviet Control in Eastern Europe | 苏联在东欧的控制
Between 1945 and 1948, pro-Soviet communist governments were installed across Eastern Europe, turning countries such as Poland, Hungary, Czechoslovakia, Romania and Bulgaria into satellite states. Elections were often rigged, and opposition groups were violently suppressed. This process was particularly blatant in Czechoslovakia, where in 1948 the communists staged a coup and established a one-party dictatorship.
1945 至 1948 年间，亲苏的共产党政府在东欧各地建立，将波兰、匈牙利、捷克斯洛伐克、罗马尼亚和保加利亚等国家变成了卫星国。选举经常被操纵，反对派团体被暴力镇压。这一过程在捷克斯洛伐克尤其明显，1948 年共产党发动政变，建立了一党专政。
Stalin used methods such as the Cominform (1947) to coordinate communist parties and the Comecon (1949) to integrate the economies of the satellite states with that of the USSR. Political purges and show trials, such as those in Hungary and Czechoslovakia, removed any leaders who showed signs of independence. Stalin’s 1953 death brought some uncertainty, but Soviet control remained firm.
斯大林利用诸如共产党和工人党情报局（1947 年）来协调共产党，以及经济互助委员会（1949 年）将卫星国经济与苏联经济一体化等手段。政治清洗和摆样子的公审，例如在匈牙利和捷克斯洛伐克发生的那样，清除了任何显示出独立迹象的领导人。1953 年斯大林去世带来了一些不确定性，但苏联的控制依然牢固。
The death of Stalin sparked new pressures, and Soviet control was severely tested by uprisings. In 1956, Hungarians rose up against their government, demanding free elections and withdrawal from the Warsaw Pact. Soviet tanks crushed the revolution, killing thousands, and a hard-line government was installed. The West condemned the invasion but took no military action. The Hungarian Uprising showed both the brutality of Soviet rule and the limits of containment: the USA was unwilling to risk war over Eastern Europe.
斯大林的去世引发了新的压力，苏联的控制受到了起义的严峻考验。1956 年，匈牙利人起义反对他们的政府，要求自由选举和退出华约。苏联坦克镇压了革命，杀害了数千人，并扶植了一个强硬派政府。西方谴责了入侵，但未采取军事行动。匈牙利起义既显示了苏联统治的残暴，也显示了遏制政策的限度：美国不愿为东欧冒战争风险。
7. The Berlin Crisis and the Berlin Wall | 柏林危机与柏林墙
Berlin remained a focus of Cold War tensions throughout the 1950s and early 1960s. West Berlin, a capitalist enclave deep inside communist East Germany, was a constant embarrassment to the USSR. Between 1949 and 1961, around 2.7 million East Germans fled to the West via Berlin, many of them skilled workers, causing a ‘brain drain’ that weakened the East German economy.
柏林在整个 1950 年代和 1960 年代初始终是冷战紧张局势的焦点。西柏林，作为共产主义东德境内的一个资本主义飞地，不断使苏联难堪。1949 至 1961 年间，约 270 万东德人经柏林逃往西方，其中许多是技术工人，导致了削弱东德经济的“人才外流”。
Khrushchev issued an ultimatum in 1958 demanding that the Western powers leave Berlin within six months, but this was rejected. At the Vienna Summit in 1961, President Kennedy refused to be bullied. On the night of 12–13 August 1961, East German troops sealed off West Berlin and began constructing a wall of concrete and barbed wire. The Berlin Wall became the most potent symbol of the division of Europe.
赫鲁晓夫在 1958 年发出最后通牒，要求西方大国在六个月内离开柏林，但遭到拒绝。在 1961 年的维也纳峰会上，肯尼迪总统拒绝被恐吓。1961 年 8 月 12 日至 13 日夜间，东德军队封锁了西柏林，开始修建一道由混凝土和铁丝网构成的墙。柏林墙成为欧洲分裂的最有力象征。
The Wall stopped the flow of refugees and stabilised the East German state, but it was a propaganda disaster for the USSR, demonstrating that people had to be imprisoned to prevent them leaving. The USA and its allies protested strongly but ultimately accepted the Wall as a way to reduce the risk of war over Berlin. The crisis further deepened the ideological divide.
柏林墙阻止了难民潮并稳定了东德国家，但对苏联而言是一场宣传灾难，因为这表明不得不囚禁人民以防止他们出逃。美国及其盟国强烈抗议，但最终接受了这道墙，将其作为降低因柏林问题爆发战争风险的一种方式。这场危机进一步加深了意识形态的分裂。
8. The Cuban Missile Crisis | 古巴导弹危机
The Cuban Missile Crisis of October 1962 was the closest the world came to nuclear war. Following the failed Bay of Pigs invasion of Cuba by US-backed exiles in 1961, Fidel Castro turned to the USSR for protection. In 1962, Khrushchev secretly began deploying nuclear missiles in Cuba, just 90 miles from the US coast. The missiles could hit major American cities within minutes.
1962 年 10 月的古巴导弹危机是世界最接近核战争的时刻。1961 年美国支持的古巴流亡者入侵猪湾失败后，菲德尔·卡斯特罗转向苏联寻求保护。1962 年，赫鲁晓夫开始在古巴秘密部署核导弹，距美国海岸仅 90 英里。这些导弹能够在数分钟内击中美国主要城市。
When US spy planes discovered the missile sites, President Kennedy imposed a naval ‘quarantine’ (blockade) around Cuba to prevent further Soviet shipments. He demanded the removal of the missiles already there. For thirteen tense days, the world watched as the two superpowers stood on the brink. Finally, Khrushchev agreed to remove the missiles in return for a secret US pledge not to invade Cuba and a public but delayed US removal of its missiles from Turkey.
当美国间谍机发现导弹基地时，肯尼迪总统对古巴实施了海上“隔离”（封锁），以阻止苏联进一步运输。他要求撤走已经在那里的导弹。在紧张的十三天里，全世界看着两个超级大国站在了悬崖边上。最终，赫鲁晓夫同意移除导弹，以换取美国秘密承诺不入侵古巴，以及美国公开但有所延迟地从土耳其撤走自己的导弹。
The crisis had profound consequences. A direct ‘hotline’ between the White House and the Kremlin was established to improve communication. The Partial Test Ban Treaty was signed in 1963, banning nuclear tests in the atmosphere. Both sides had stared into the abyss and took steps to avoid future confrontations. Khrushchev was weakened by the crisis, which contributed to his removal in 1964.
这场危机产生了深远的影响。白宫和克里姆林宫之间建立了一条直接“热线”，以改进沟通。1963 年签署了《部分禁止核试验条约》，禁止在大气层进行核试验。双方都曾凝视深渊，并采取措施避免未来的对抗。赫鲁晓夫因危机而受到削弱，这促成了他于 1964 年被免职。
9. The Vietnam War | 越南战争
The Vietnam War was a major theatre of the Cold War and a devastating conflict that lasted from the mid-1950s to 1975. After defeating French colonial forces at Dien Bien Phu in 1954, Vietnam was temporarily divided at the 17th parallel. The USA supported the anti-communist government in the South, while the communist North, under Ho Chi Minh, sought reunification. The US policy of containment turned Vietnam into a test case for the ‘Domino Theory’, the belief that if one country fell to communism, its neighbours would follow.
越南战争是冷战的一个重要战场，也是一场从 1950 年代中期持续到 1975 年的毁灭性冲突。在 1954 年奠边府击败法国殖民军队后，越南在十七度线被暂时分割。美国支持南方的反共政府，而以胡志明为首的共产主义北方寻求统一。美国的遏制政策将越南变成了“多米诺骨牌理论”的试验场，这一理论认为，若一个国家落入共产主义，其邻国将会相继倒台。
American involvement escalated dramatically in the 1960s. The Gulf of Tonkin Resolution (1964) gave President Johnson broad powers to wage war. By 1968, there were over 500 000 US troops in Vietnam. Despite massive bombing campaigns, the USA struggled to defeat the Vietcong guerrillas, who used their knowledge of the jungle and a network of tunnels. The Tet Offensive of 1968 was a military failure for the communists but a psychological victory, turning US public opinion against the war.
美国的介入在 1960 年代急剧升级。东京湾决议（1964 年）赋予约翰逊总统发动战争的广泛权力。到 1968 年，在越南的美军已超过 50 万。尽管进行了大规模轰炸，美国仍难以击败越共游击队，后者利用了他们对丛林的认识和地道网络。1968 年的春节攻势对共产党而言是一次军事失败，却是一次心理胜利，使美国舆论转向反战。
The war proved deeply unpopular at home and abroad, fuelling massive anti-war protests. President Nixon pursued ‘Vietnamisation’, gradually withdrawing US troops and building up South Vietnamese forces. A peace agreement was reached in Paris in 1973. Two years later, North Vietnamese forces captured Saigon, and Vietnam was reunited under communist rule. The war cost millions of lives and severely damaged America’s confidence and international reputation.
这场战争在国内外都极不得人心，引发了大规模反战抗议。尼克松总统推行“越南化”，逐步撤出美军并加强南越军队。1973 年在巴黎达成和平协议。两年后，北越部队攻占西贡，越南在共产主义统治下实现统一。这场战争夺去了数百万人的生命，严重损害了美国的信心和国际声誉。
10. The End of the Cold War | 冷战的结束
The 1980s saw a renewed intensification of Cold War tensions under US President Ronald Reagan, who described the USSR as the ‘Evil Empire’ and launched a massive military build-up, including the Strategic Defense Initiative (‘Star Wars’). However, by the mid-1980s, the Soviet Union was facing deep economic stagnation, a costly war in Afghanistan and growing calls for reform.
1980 年代，在将苏联称为“邪恶帝国”并启动了包括战略防御倡议（“星球大战”）在内的大规模军备扩张的美国总统罗纳德·里根领导下，冷战紧张局势再度加剧。然而，到 1980 年代中期，苏联正面临严重的经济停滞、一场代价高昂的阿富汗战争以及日益高涨的改革呼声。
Mikhail Gorbachev came to power in 1985 and introduced two key policies: ‘glasnost’ (openness) and ‘perestroika’ (restructuring). Glasnost allowed greater freedom of speech and a critical re-examination of Soviet history, while perestroika attempted to reform the inefficient command economy. Gorbachev also pursued a ‘new thinking’ in foreign policy, seeking to reduce tensions with the West and end the arms race.
米哈伊尔·戈尔巴乔夫于 1985 年上台执政，并推出了两项关键政策：“公开性”和“改革”。公开性允许更大的言论自由和对苏联历史的批判性重新审视，而改革则试图重整缺乏效率的指令性经济。戈尔巴乔夫还推行外交政策“新思维”，力图缓和与西方的紧张关系并结束军备竞赛。
A series of summits and arms control agreements, including the Intermediate-Range Nuclear Forces (INF) Treaty (1987), marked a dramatic thaw. Crucially, Gorbachev declared that the USSR would no longer intervene in the affairs of Eastern European satellite states – the so-called ‘Sinatra Doctrine’. Throughout 1989, revolutions swept across Eastern Europe, and the Berlin Wall fell in November. The Warsaw Pact was dissolved, and the Soviet Union itself ceased to exist in December 1991, ending the Cold War.
包括《中程核力量条约》（1987 年）在内的一系列峰会和军备控制协议标志着一个戏剧性的解冻。至关重要的是，戈尔巴乔夫宣布苏联将不再干涉东欧卫星国的内政——即所谓的“辛纳屈主义”。整个 1989 年，革命浪潮席卷东欧，柏林墙于 11 月倒塌。华约组织解体，苏联自身亦于 1991 年 12 月不复存在，冷战遂告终结。
