APWH · Unit 8— c. 1945 — c. 1991 —

Two superpowers, a hundred new states.

NATO, Warsaw Pact, proxy wars; Indian and African independence; the long unwinding of empire.

What you need to know

The Cold War (1947–1991) divided the world into U.S. and Soviet blocs, fought through proxy wars in Korea, Vietnam, Afghanistan, and (one near-nuclear miss) Cuba. In the same decades, decolonization replaced European empires with ~100 new nation-states: India and Pakistan in 1947; Ghana in 1957; most of Africa by 1965; Vietnam reunified in 1975. The two stories are intertwined—superpowers competed for influence in every newly independent state.

    Setting the Stage for the Cold War

    Yalta, Potsdam, ideological divide.WOR · GOV

    What to study

    The U.S. and USSR were uneasy allies during WWII; the Yalta Conference (Feb 1945) and Potsdam (July 1945) papered over disagreements about postwar Eastern Europe. By 1947, Stalin had installed communist governments across Eastern Europe; Churchill’s “Iron Curtain” speech (1946) named the divide; Truman’s 1947 doctrine pledged to contain communism. The Marshall Plan (1948) rebuilt Western Europe under U.S. terms; the Soviet Cominform organized the East. The two ideological blocs would dominate global politics for 45 years.

    Key termsYalta · Potsdam · Iron Curtain · Truman Doctrine · Marshall Plan · Containment
    Exam focusThe Cold War wasn’t inevitable. It emerged from specific decisions (Stalin’s Eastern Europe, Truman’s containment).
    Primary sourceHarry S. Truman, The Truman Doctrine, 1947 — Yale Avalon Project
    Truman frames the Cold War as a global struggle between democracy and totalitarianism — the speech that set the terms of U.S. containment policy and defined the post-WWII order.

    “All men are created equal. They are endowed by their Creator with certain inalienable rights; among these are Life, Liberty, and the pursuit of Happiness… The whole Vietnamese people, animated by a common purpose, are determined to fight to the bitter end against any attempt by the French colonialists to reconquer their country.” — Ho Chi Minh, Declaration of Independence of the Democratic Republic of Vietnam, Hanoi, September 2, 1945

    Ho Chi Minh (1890–1969) opened Vietnam’s Declaration of Independence by quoting both the U.S. Declaration of Independence and the French Declaration of the Rights of Man. The gesture was deliberate: he was using the Enlightenment’s own language to demand that its promises apply to colonized peoples. The United States chose to support French reconquest of Vietnam anyway. This document is the starting point for understanding how the Cold War looked to peoples who had just survived colonialism.

    The Cold War

    NATO, Warsaw Pact, proxy wars, brinkmanship.WOR

    What to study

    NATO (1949) and the Warsaw Pact (1955) institutionalized the divide. The Cold War “hot” wars happened in proxies: Korea (1950–53), Vietnam (1955–75), Afghanistan (1979–89). The most dangerous moment was the Cuban Missile Crisis (October 1962). Mutually Assured Destruction (MAD) prevented direct nuclear war but raised constant risks. Détente in the 1970s (SALT, Helsinki Accords) eased tensions, then Reagan-era escalation (1980s) preceded the Soviet collapse (1991). The fall of the Berlin Wall (1989) was the symbolic end.

    Key termsNATO · Warsaw Pact · Korean War · Vietnam War · Cuban Missile Crisis · MAD · Détente
    Exam focusDon’t treat the Cold War as monolithic. It had hot phases and cold phases, near-misses and routine years.
    Primary sourceNSC-68, United States Objectives and Programs for National Security, 1950 — Yale Avalon Project
    The secret policy paper doubling U.S. defense spending — primary evidence of how Cold War ideology drove military-industrial buildup and shaped domestic politics on both sides.

    “We have known exhausting labor extracted from us by force, morning, noon, and night, in return for pay that allowed us neither to eat enough nor to dress ourselves or sleep in decent lodging. We have known ironies, insults, blows that we endured morning, noon, and night, because we were Negroes.” — Patrice Lumumba, Independence Day address, Leopoldville, June 30, 1960 (translated from French)

    Lumumba (1925–1961), the first Prime Minister of the newly independent Congo, delivered this speech at a ceremony attended by Belgian King Baudouin. When the king praised Belgian colonialism as a gift to the Congolese, Lumumba responded directly, describing what colonialism had actually meant. He was assassinated eight months later, with documented CIA involvement. His speech—and his death—document why the Cold War’s proxy conflicts in Africa were experienced as extensions of colonialism rather than as contests between freedom and communism. Read the source →

    Effects of the Cold War

    Arms race, proxy wars, ideological competition.WOR · TEC

    What to study

    Effects: nuclear arms race (~70,000 warheads at peak); superpower-funded proxy wars and coups in Iran (1953), Guatemala (1954), Congo (1961), Chile (1973); space race (Sputnik 1957, Apollo 11 1969); global ideological competition for influence; CIA and KGB shaping politics in dozens of countries; massive military-industrial sectors in both superpowers. The Cold War also drove decolonization—newly independent states could play superpowers off each other for aid.

    Primary sourceNikita Khrushchev, Secret Speech (On the Cult of Personality), 1956 — Fordham Internet History Sourcebooks
    Khrushchev denounces Stalin to the Party Congress — the speech that triggered de-Stalinization and cracked the Soviet bloc’s ideological unity, with global Cold War effects.
    Whose story is missing?

    “Latin America is the region of open veins. Everything, from the discovery until our times, has always been transmuted into European—or later United States—capital, and as such has accumulated in distant centers of power. Everything: the soil, its fruits and its mineral-rich depths, the people and their capacity to work.” — Eduardo Galeano, Open Veins of Latin America: Five Centuries of the Pillage of a Continent, 1971 (translated from Spanish)

    Galeano (1940–2015) wrote this book as a documented economic history of Latin America’s relationship to external powers from the conquest to the Cold War. It was immediately banned by military dictatorships in Uruguay, Argentina, and Chile. In 2009, Venezuelan President Hugo Chávez gave a copy to Barack Obama at a summit—the book went to the top of the bestseller list that day. It represents the Latin American perspective on why the Cold War’s economic conflicts were not between capitalism and communism but between wealth extraction and self-determination.

    Spread of Communism After 1900

    Russia, China, Cuba, Vietnam.WOR · GOV

    What to study

    Communist revolutions had distinctive paths. Russia (1917): Bolsheviks seized power amid WWI collapse; Stalin built a totalitarian state; Five-Year Plans, Great Purge, victory in WWII. China (1949): Mao’s peasant-based revolution after a long civil war; Great Leap Forward and Cultural Revolution were catastrophic. Cuba (1959): Castro’s 26th of July Movement overthrew Batista; pushed into Soviet orbit by U.S. hostility. Vietnam (1945–): Ho Chi Minh’s Viet Minh briefly resisted Japanese occupation in 1945, fought a long war against France (1946–1954), then a longer one against the U.S. (1955–1975); unified by 1976.

    Primary sourceHo Chi Minh, Declaration of Independence of the Democratic Republic of Vietnam, 1945 — Fordham Internet History Sourcebooks
    Ho Chi Minh opens with Jefferson’s words — modeling Vietnamese independence on American ideals — evidence of how communist movements used anti-colonial nationalism to spread after 1900.

    “The guerrilla fighter is a social reformer, who takes up arms responding to the angry protest of the people against their oppressors, and who fights in order to change the social system that keeps all his unarmed brothers in ignominy and misery.” — Ernesto “Che” Guevara, Guerrilla Warfare, 1961

    Guevara (1928–1967) was an Argentine doctor who joined the Cuban Revolution and later attempted to spread revolutionary movements across Latin America and Africa before his capture and execution in Bolivia. His writings framed communist revolution not as an ideological abstraction but as a response to specific material conditions—poverty, landlessness, and foreign economic domination. His account shows what the “spread of communism” looked like from the inside: not Soviet conspiracy, but local grievance finding a global framework. Read the source →

    Decolonization After 1900

    India, Africa, Vietnam, Algeria.WOR · CDI

    What to study

    Decolonization (1947–1975) replaced empires with nation-states. India and Pakistan (1947): Gandhi’s nonviolent campaign + Muslim League pressure + British exhaustion. Vietnam: Viet Minh defeated France at Dien Bien Phu (1954), then beat the U.S. by 1975. Algeria (1954–62): brutal war for independence from France. Sub-Saharan Africa: Ghana first (1957), then most by 1965. Apartheid South Africa held out until 1994. Each independence had its leaders, methods, and aftermaths—but all drew on Enlightenment vocabulary and global anti-colonial solidarity.

    “Decolonization is always a violent phenomenon… The naked truth of decolonization evokes for us the searing bullets and bloodstained knives which emanate from it. For if the last shall be first, this will only come to pass after a murderous and decisive struggle.” — Frantz Fanon, The Wretched of the Earth, 1961 (translated from French by Constance Farrington)

    Fanon (1925–1961), a psychiatrist from Martinique who joined the Algerian independence movement, wrote this book as a psychological and political analysis of colonialism and decolonization. He argued that colonialism was not merely economic or political but operated through the systematic destruction of colonized people’s self-image and culture—and that decolonization therefore required not just political independence but psychological liberation. His book was banned in France and became foundational for anti-colonial movements worldwide. Read the source →

    Newly Independent States

    Postcolonial state-building.GOV · ECN

    What to study

    Newly independent states faced enormous challenges. Many had borders drawn by colonial powers without ethnic or geographic logic (Africa, the Middle East). Most had economies structured for raw-material export, not industrialization. Many faced superpower interference: U.S.-backed Mobutu in Congo, Soviet-backed Marxist regimes in Ethiopia and Angola. Some pursued non-alignment (Nehru’s India, Tito’s Yugoslavia, Nasser’s Egypt). Others (South Korea, Taiwan, Singapore) industrialized rapidly under authoritarian capitalism. Outcomes ranged widely.

    “Our independence is meaningless unless it is linked up with the total liberation of Africa… Neo-colonialism is the worst form of imperialism. For those who practise it, it means power without responsibility; and for those who suffer from it, it means exploitation without redress.” — Kwame Nkrumah, Neo-Colonialism: The Last Stage of Imperialism, 1965

    Nkrumah (1909–1972) led Ghana to independence in 1957—the first sub-Saharan African nation to gain independence from European rule. His 1965 book argued that political independence had not ended colonialism but transformed it: formerly colonized states were now economically controlled by former colonial powers through debt, trade terms, and political interference. He was overthrown in a CIA-supported coup in 1966. His concept of neo-colonialism shaped economic analysis of the Global South for decades. Read the source →

    Global Resistance to Established Power

    Civil rights, anti-apartheid, women’s movements.SOC · CDI

    What to study

    The same era saw mass movements challenging power within established states. The U.S. civil rights movement (1955–68) pushed legal and social desegregation. The anti-apartheid movement built international solidarity that helped end South African white-minority rule (1994). Women’s liberation (second-wave feminism, c. 1963–) reshaped Western law and culture; women’s movements globalized through the UN Decade for Women. Indigenous rights movements (the U.S., Canada, Australia, Latin America) demanded recognition and land. These movements borrowed from each other.

    “I question America. Is this America, the land of the free and the home of the brave, where we have to sleep with our telephones off the hooks because our lives be threatened daily, because we want to live as decent human beings, in America?” — Fannie Lou Hamer, testimony before the Credentials Committee, Democratic National Convention, Atlantic City, August 22, 1964

    Hamer (1917–1977), a Mississippi sharecropper and civil rights activist, testified before the Democratic Party’s credentials committee to demand that the integrated Mississippi Freedom Democratic Party be seated instead of the all-white delegation. President Johnson, afraid of losing Southern white votes, arranged for her testimony to be interrupted. Her question—broadcast after the convention—exposed the gap between U.S. claims to represent democracy globally and the treatment of Black citizens at home. It became one of the defining statements of the civil rights movement. Read the source →

    End of the Cold War

    Soviet collapse and its consequences.WOR

    What to study

    The Soviet collapse came faster than most expected. Mikhail Gorbachev’s glasnost and perestroika reforms (1985–) opened up speech and limited markets but exposed the system’s contradictions. Eastern Europe broke away in 1989: Solidarity-led Poland, the Berlin Wall fell, Czechoslovakia’s Velvet Revolution. The USSR itself dissolved December 1991 into 15 successor states. Effects: Cold War alliances reshaped (NATO expanded east); ethnic conflicts surfaced (Yugoslavia’s wars 1991–2001); a brief U.S.-led “unipolar moment”; eventual Russian revanchism and Chinese rise to fill the vacuum.

    “Our country is not flourishing. The previous regime, armed with its arrogant and intolerant ideology, reduced man to a force of production and nature to a tool of production. It made out of once-proud citizens mere cogs in a monstrous, thudding, smelling machine.” — Václav Havel, inaugural address as President of Czechoslovakia, Prague, January 1, 1990 (translated from Czech)

    Havel (1936–2011) was a Czech playwright and dissident who spent years in prison under the communist government before becoming the first president of post-communist Czechoslovakia. His inaugural address described not Soviet ideology’s abstract failure but what it had actually meant to live inside it: the degradation of individuals into instruments of a system, the destruction of civic life, and the poisoning of the environment. His account represents the Eastern European experience of communism from the inside—the perspective missing from both Soviet propaganda and Western Cold War narratives. Read the source →
