AP World History: Modern › Causation in Global Conflict
By the early twentieth century, Japan had industrialized rapidly, defeated China (1894–1895) and Russia (1904–1905), and gained influence in Korea and Manchuria. During World War I, Japan seized German holdings in Shandong and the Pacific and later issued the Twenty-One Demands to China. In the 1930s, Japan established Manchukuo and expanded further on the Asian mainland, arguing it needed resources and security. Which development most directly contributed to Japan’s turn toward aggressive expansionism in this period?
Dependence on imported raw materials and the belief that empire could secure resources and buffer zones against rival powers
The spread of Marxist internationalism among Japanese elites, which led them to reject nationalism and pursue global disarmament
The immediate collapse of the Meiji state into decentralized daimyo rule, enabling private armies to invade neighboring territories
A binding peace treaty that prohibited Japanese trade, forcing leaders to replace commerce with warfare to avoid starvation
A long-standing policy of total isolation that prevented Japan from learning Western military techniques, leaving conquest as its only option
Explanation
Japan's aggressive expansionism in the early twentieth century was caused by its rapid industrialization and dependence on imported resources, pushing leaders to seek empire for security and self-sufficiency. Victories in the Sino-Japanese and Russo-Japanese Wars emboldened Japan, granting territories like Korea and influence in Manchuria, which were seen as vital buffers against rivals. During World War I, seizing German holdings and issuing the Twenty-One Demands to China reflected a strategy to dominate Asia amid global distractions. The 1930s invasion of Manchuria and establishment of Manchukuo were justified as necessary for raw materials like coal and iron, amid economic pressures from the Great Depression. This causation shows how resource scarcity and strategic imperatives can drive imperial aggression, escalating regional conflicts into broader confrontations.
After 1945, many Asian and African colonies gained independence. New states often faced border disputes, ethnic divisions, and economic dependence. Superpowers offered military and financial aid, sometimes supporting coups or insurgencies to secure allies. Conflicts in places like Angola and Afghanistan became prolonged and destructive. Which factor most directly explains why decolonization sometimes intensified global conflict during the Cold War?
Decolonization eliminated all strategic rivalries by creating universally prosperous economies that required no foreign investment or alliances
Newly independent states were insulated from outside influence by strict global neutrality laws that prevented any foreign aid or intervention
The immediate disappearance of nationalism, which reduced civil wars and removed reasons for outside powers to become involved
A global agreement to dissolve the United Nations, which directly caused every decolonizing state to unite into one empire
Power vacuums and contested legitimacy in new states invited superpower intervention, turning local struggles into proxy wars within ideological competition
Explanation
Decolonization intensified Cold War conflicts by creating power vacuums in new states, inviting superpower interventions in local struggles. Border disputes and ethnic divisions made nations vulnerable to aid-fueled insurgencies. Proxy wars in Angola and Afghanistan prolonged destruction. This causation demonstrates how independence processes can entangle with global rivalries, escalating regional issues internationally.
In the 1930s, Italy invaded Ethiopia, Japan expanded in China, and Germany annexed Austria and demanded territory in Czechoslovakia. The League of Nations issued condemnations but lacked effective enforcement, and major powers often prioritized domestic recovery or avoided confrontation. Aggressors interpreted limited responses as weakness and continued expansion. Which factor most directly explains why collective security failed to prevent the outbreak of World War II?
The total absence of nationalist ideologies, which made populations unwilling to support any foreign policy initiatives
A universal commitment to immediate disarmament, which removed all armies and made it impossible for any state to initiate aggression
The rapid success of decolonization, which redirected all European militaries away from Europe and toward peaceful development projects
The League’s lack of enforcement power and the reluctance of major powers to impose costs on aggressors, encouraging further expansion
The discovery of new trade routes that eliminated strategic chokepoints, removing reasons for states to pursue territorial conquest
Explanation
Collective security failed to prevent World War II due to the League of Nations' lack of enforcement power and major powers' reluctance to confront aggressors. Invasions like Italy's in Ethiopia and Japan's in Manchuria met only verbal condemnations, emboldening further expansion. Domestic priorities, such as economic recovery, deterred interventions, while appeasement policies misinterpreted aggression as limited. Aggressors viewed weak responses as opportunities, leading to annexations in Austria and Czechoslovakia. This causation reveals how institutional weaknesses and isolationist tendencies can allow localized aggressions to cascade into global war.
In 1950, North Korean forces crossed the 38th parallel, aiming to unify Korea under a communist government. The United Nations, led largely by the United States, intervened to support South Korea, while China entered the war to prevent a hostile force on its border. Fighting devastated the peninsula and ended in an armistice rather than a peace treaty. Which broader Cold War dynamic most directly explains why the Korean War escalated into a major international conflict?
The rapid collapse of Chinese state authority, which prevented any foreign involvement and kept the war strictly local
The immediate formation of the European Union, which redirected U.S. and Soviet attention away from Asia and toward trade policy
A global agreement to dismantle all militaries, which forced states to rely on mercenaries and prolonged the war indefinitely
Superpower containment and security concerns, which turned a civil and regional conflict into a proxy struggle involving major military intervention
The complete absence of ideological rivalry after 1945, which made great powers indifferent to political outcomes in Asia
Explanation
The Korean War escalated into an international conflict due to Cold War containment dynamics, where superpowers viewed it as a proxy struggle for global influence. North Korea's 1950 invasion aimed at unification under communism, prompting U.N. intervention led by the U.S. to prevent domino-effect spread. China's entry to secure its border intensified the war, reflecting fears of encirclement. The armistice without a treaty left lasting divisions. This causation illustrates how ideological and security concerns can internationalize civil conflicts, embedding them in broader superpower confrontations.
After World War I, the Treaty of Versailles imposed reparations on Germany, limited its military, and assigned war guilt. In the 1920s Germany faced hyperinflation and political instability; in the 1930s the Great Depression intensified unemployment and social distress. The Nazi Party promised economic revival, rejected Versailles, and promoted militarism and racial nationalism, rearming and remilitarizing the Rhineland. Which factor most directly explains the rise of extremist politics that helped lead to World War II in Europe?
Economic crisis combined with resentment toward punitive peace terms, enabling leaders to mobilize support for revisionism and rearmament
The rapid success of liberal international organizations, which removed all grievances and pushed voters toward radical antiwar parties
A sudden demographic collapse caused by epidemic disease, which created labor shortages and forced Germany to invade neighbors for workers
The immediate decolonization of Africa, which redirected German nationalism toward overseas development rather than European expansion
The discovery of vast oil reserves in Germany, which made conquest unnecessary and encouraged isolationist politics
Explanation
The rise of extremist politics in interwar Germany was directly caused by the economic hardships of the Great Depression combined with resentment over the Treaty of Versailles' punitive terms. Hyperinflation in the 1920s and mass unemployment in the 1930s created social distress, eroding faith in the Weimar Republic and making voters receptive to radical solutions. The Nazis capitalized on this by promising economic revival, rejecting Versailles' war guilt and reparations, and promoting militarism and racial nationalism. Actions like rearming and remilitarizing the Rhineland appealed to those seeking to restore German prestige. This causation highlights how economic crises and perceived injustices can foster authoritarian regimes, setting the stage for revisionist policies that lead to global war.
In the Middle East after World War II, the creation of Israel in 1948 and subsequent Arab-Israeli wars displaced populations and hardened regional rivalries. During the Cold War, the United States and the Soviet Union provided arms and aid to different regional partners, while oil became strategically vital to industrial economies. Conflicts such as the 1973 war influenced global energy markets and diplomacy. Which factor most directly explains why Middle Eastern conflicts often became entangled in global Cold War tensions?
The end of global trade after 1945, which eliminated any reason for outside powers to care about Middle Eastern stability
The immediate dissolution of all regional states into a single federation, which removed borders and ended external interventions
Superpower pursuit of allies and access to oil, leading them to arm regional states and treat local wars as part of broader rivalry
A universal commitment to pacifism among regional leaders, which prevented wars but increased superpower propaganda campaigns
The region’s lack of strategic resources, which made it irrelevant to superpower competition and limited outside involvement
Explanation
Middle Eastern conflicts entangled in Cold War tensions due to superpowers' pursuit of allies and oil access, arming regional states amid local rivalries. The 1948 creation of Israel and Arab-Israeli wars created flashpoints, with U.S. and Soviet aid to opposing sides. Oil's strategic importance amplified interventions, as in the 1973 war's impact on global markets. This causation shows how resource competition and alliance-building can globalize regional disputes, integrating them into ideological struggles.
During World War II, Germany pursued blitzkrieg tactics early on, but later fought a prolonged war of attrition against the Soviet Union and faced strategic bombing from the Allies. The United States mobilized industrial output on a massive scale, supplying itself and allies. By 1944–1945, Germany confronted multiple fronts, resource shortages, and sustained bombing. Which factor most directly contributed to the Allied victory in Europe?
The immediate neutrality of the Soviet Union after 1941, which freed Germany to concentrate forces and end the war quickly
The abolition of air power by international treaty, which eliminated bombing and allowed Germany to maintain production unimpeded
German access to unlimited oil reserves, which ensured continuous mechanized warfare and prevented supply crises on the Eastern Front
The Allies’ limited industrial capacity, which forced Germany to overproduce weapons and collapse under surplus goods
Allied industrial and logistical superiority, enabling sustained multi-front operations that overstretched German resources and manpower
Explanation
Allied victory in Europe during World War II was caused by industrial and logistical superiority, enabling multi-front operations that overstretched Germany. U.S. production supplied allies, while strategic bombing disrupted German industry. The Eastern Front drained German resources against Soviet manpower. This causation shows how economic mobilization can determine outcomes in total wars, overwhelming adversaries through sustained pressure.
In the early twentieth century, the Ottoman Empire faced nationalist movements among subject peoples, European intervention, and internal reform efforts. After the Balkan Wars and World War I, the empire collapsed, and new states emerged under mandates and treaties. Competing promises to Arabs and Zionists during wartime diplomacy shaped postwar disputes. Which factor most directly helps explain how the collapse of the Ottoman Empire contributed to later regional conflicts with global implications?
The immediate end of European involvement in the Middle East, which removed strategic interest and prevented future conflicts
The abolition of oil production across the region, which made the Middle East economically irrelevant to global powers
The empire’s transformation into a democratic federation that peacefully resolved ethnic tensions and reduced the likelihood of external intervention
The creation of new borders and mandates that ignored local identities, fostering disputes that attracted outside powers and persisted into the Cold War era
The replacement of nationalism with universal monarchism, which eliminated separatist movements and stabilized borders permanently
Explanation
The Ottoman Empire's collapse contributed to regional conflicts by creating borders and mandates ignoring local identities, fostering disputes with global implications. Post-World War I treaties like Sykes-Picot divided territories, sparking Arab and Zionist grievances. Ethnic minorities and contested areas led to instability, attracting Cold War interventions. This causation illustrates how imperial dissolutions can seed enduring conflicts, drawing in external powers over time.
In 1919, the Paris Peace Conference redrew borders and created new states in Europe and the Middle East. Many ethnic groups found themselves as minorities within new countries, and some borders were contested. While the settlement aimed to prevent future war, revisionist states later sought to overturn it. Which factor most directly helps explain why the post–World War I peace settlement contributed to later conflict?
It required immediate global disarmament enforced by a powerful League army, preventing any state from rearming or threatening neighbors
It ended economic competition by abolishing tariffs worldwide, making territorial conquest irrelevant to national prosperity
It restored all pre-1871 empires intact, ensuring that traditional dynasties could manage ethnic tensions peacefully
It created grievances through punitive terms and unstable borders, encouraging revisionism and nationalist claims that undermined interwar stability
It eliminated nationalism by granting every ethnic group its own perfectly homogeneous state, removing any reason for future disputes
Explanation
The post-World War I settlement contributed to later conflict by creating grievances through punitive terms and unstable borders, encouraging revisionism. Ethnic minorities and contested territories fueled nationalism. Revisionist states sought to overturn it. This causation reveals how peace treaties can sow seeds for future wars if perceived as unjust.
In 1917, Russia experienced revolution amid war exhaustion, food shortages, and dissatisfaction with the tsarist regime. The Bolsheviks withdrew from World War I and later fought a civil war, eventually establishing the Soviet Union. In many countries, elites feared communist revolution, while leftist movements drew inspiration from Bolshevik success. Which outcome most directly shows how the Russian Revolution contributed to global conflict in the twentieth century?
It helped create enduring ideological polarization, contributing to civil conflicts and later Cold War confrontations between capitalist and communist blocs
It caused immediate global economic prosperity, reducing competition for markets and making major wars unlikely
It eliminated ideological rivalry by convincing all governments to adopt a single-party socialist system and abandon militaries
It ended European imperialism overnight, removing colonial tensions that had fueled international wars since the 1800s
It directly produced nuclear weapons in 1918, leading to instant worldwide deterrence and permanent peace
Explanation
The Russian Revolution contributed to twentieth-century global conflict by creating ideological polarization that fueled civil wars and Cold War rivalries. The Bolsheviks' 1917 seizure of power amid World War I exhaustion led to Russia's withdrawal from the war and a civil war, establishing the Soviet Union as a communist model. This inspired leftist movements worldwide while alarming elites who feared revolution, prompting interventions and suppressions. The spread of communism versus capitalism set the stage for proxy conflicts and bloc formations after World War II. This causation demonstrates how revolutionary changes can propagate ideological divides, turning internal upheavals into sustained global confrontations.
