Container shipping, aviation, and digital communication
Communication technology changed global exchange in stages across this period, not through the internet alone. Radio connected mass audiences across long distances earlier in the twentieth century, well before computers, satellites, fiber-optic networks, mobile phones, and the internet further compressed the time and cost of moving information. Digital communication networks eventually enabled near-instant global exchange of information and supported new forms of commerce, coordination, and organizing that would have been impossible under earlier communication speeds. Standardized shipping containers and improved logistics reduced handling costs and helped expand global supply chains, while commercial aviation accelerated the movement of people, high-value goods, tourism, and migration across long distances in ways that made routine international travel newly practical for far more people than before. Energy technology expanded alongside communication and transport: petroleum became a dominant global energy source powering transportation, industry, and electricity generation, while nuclear power later added a further, more concentrated source of electricity generation in several states. Reproductive technology also reshaped demographic patterns directly: more effective and widely available birth control gave many women substantially greater control over fertility during this period, contributing to declining birth rates in much of the world. Agricultural technology changed food production on a comparable scale: the Green Revolution’s high-yield crop varieties, synthetic fertilizers, and expanded irrigation sharply increased food production in many regions, though the benefits and environmental costs of this intensified agriculture were distributed unevenly.
Use this evidence. Radio demonstrates that global communication technology accelerated in stages well before the internet, not in one single late-twentieth-century leap. Containerization demonstrates that globalization after 1900 depended on unglamorous logistical innovation, not only the more visible digital communication technologies, to achieve its actual scale. Birth control demonstrates a technology whose primary consequence was demographic and social rather than commercial, a distinct category worth separating from communication, transport, and energy technology in any argument about this unit’s required technological range.
Chronology check. Public and commercial internet use expanded rapidly mainly during the 1990s, not the 1950s or 1960s; placing mass internet adoption in those earlier decades misplaces this evidence by several decades. Containerization and global supply chain expansion belong to the late twentieth century, not to nineteenth-century steam technology.
Disease, public health, and global inequality
Vaccination, antibiotics, sanitation, disease surveillance, and international public-health cooperation together reduced mortality from many infectious diseases during this period, extending life expectancy significantly in much of the world, but disease did not simply disappear as a global problem. Three distinct patterns are worth separating rather than treating "disease" as one uniform category. Poverty and weak sanitation or health infrastructure allowed diseases such as malaria, tuberculosis, and cholera to remain major threats in many lower-income regions even as they became far less significant elsewhere, making these poverty-associated diseases a direct marker of global inequality in health outcomes. New or newly recognized epidemic diseases spread more easily through an increasingly connected world, including the 1918 influenza pandemic, later Ebola outbreaks, and HIV/AIDS, demonstrating that global connectivity could accelerate disease transmission just as it accelerated trade and communication. At the same time, longer life expectancy in much of the world increased the relative importance of diseases associated with aging, including heart disease and Alzheimer’s disease, a pattern that only became prominent once other causes of early death had already declined substantially. The World Health Assembly called for global smallpox eradication in 1958, and the World Health Organization launched its eradication programme in 1959; progress was slow until an intensified programme began in 1967, combining vaccination with active surveillance and containment. An international commission certified the disease eradicated in December 1979, and the World Health Assembly formally declared global eradication in May 1980, marking one of the most complete public-health victories in this book’s coverage and a clear example of coordinated international action succeeding against an epidemic disease. HIV/AIDS later demonstrated a very different pattern: unequal treatment access, social stigma, uneven state capacity, and global inequality shaped its consequences unevenly across regions and populations, even as it prompted substantial global activism, research investment, and new public-health institutions in response.
Use this evidence. Naming the specific disease category, poverty- associated, emergent epidemic, or longevity-associated, before citing an example demonstrates the mechanism the exam expects rather than treating any disease as interchangeable evidence for any disease-related claim. The contrast between smallpox eradication’s success and HIV/AIDS’s demonstrated limits shows that global public-health cooperation produced uneven outcomes depending on the specific disease and the resources and political will mobilized against it.
Chronology check. The World Health Assembly’s 1958 call for eradication, the WHO’s 1959 programme launch, the 1967 intensified programme, the December 1979 certification, and the May 1980 formal declaration are five distinct milestones spanning more than two decades, not one event; collapsing them into a single "certified 1980" date loses this sequence. None of these dates should be confused with the invention date of the smallpox vaccine itself, which predates this campaign considerably.
Climate change, pollution, and international environmental politics
Fossil-fuel use, industrial production, deforestation, urbanization, and mass consumption increased pollution and intensified environmental pressure during this period, connecting environmental change directly to the industrialization and economic growth covered earlier in this book. Environmental change also extended beyond pollution and climate into competition over basic resources: desertification reduced usable agricultural land in a number of regions, and rising freshwater consumption from growing populations, cities, agriculture, and industry intensified competition over water resources in areas where supply was already limited. Environmental activism and new regulations expanded in many countries as pollution, nuclear risk, deforestation, desertification, water stress, and climate concerns became increasingly visible and politically salient. Scientific concern about greenhouse-gas emissions encouraged international debate and agreements over how to reduce climate-related risk, though international environmental negotiations produced ongoing disagreement over how to distribute the costs and responsibilities of addressing these problems among different states.
Use this evidence. International disagreement over how to distribute climate-related costs and responsibilities demonstrates that environmental cooperation, even when scientifically motivated, still had to navigate real political and economic conflicts among states with very different circumstances.
Bretton Woods, GATT/WTO, and global finance
The International Monetary Fund and World Bank emerged from the 1944 Bretton Woods conference, part of wartime planning for a more stable postwar monetary and development order. The General Agreement on Tariffs and Trade governed much multilateral trade beginning when it entered into force in 1948, functioning in this role until the World Trade Organization began operating in 1995 with broader rules covering goods, services, and other areas of international commerce. Multinational corporations expanded cross-border production, investment, and sourcing during this period, organizing supply chains across national borders in ways that took direct advantage of reduced trade barriers and improved transport and communication technology covered earlier in this unit.
Use this evidence. The forty-seven-year gap between GATT’s 1948 entry into force and the WTO’s 1995 founding demonstrates that international trade governance developed gradually through a specific institutional sequence, not as a single simultaneous creation.
Chronology check. The Bretton Woods conference occurred in 1944, and the IMF began operations in 1947; the WTO did not exist until 1995 and should not be called a Bretton Woods institution created at that 1944 conference. GATT, entering into force in 1948, functioned as the WTO’s institutional predecessor, not its successor.
In the late twentieth century, many governments expanded free-market policies and reduced state economic control, a shift often called economic liberalization. The United States under Ronald Reagan, Britain under Margaret Thatcher, China under Deng Xiaoping, and Chile under Augusto Pinochet all pursued significant market-oriented economic reform during this period, even though their political systems, from democratic to authoritarian, differed sharply from one another. Advances in information technology also supported the growth of knowledge economies, concentrated in places such as the United States, Japan, and Finland, where economic value increasingly depended on information, software, and specialized expertise rather than raw material extraction or manufacturing alone. At the same time, manufacturing itself shifted geographically, expanding substantially in parts of Asia and Latin America, including Vietnam, Bangladesh, Mexico, and Honduras, as firms sought lower production costs within increasingly integrated global supply chains.
Use this evidence. Reagan, Thatcher, Deng, and Pinochet demonstrate that late-twentieth-century economic liberalization crossed sharply different political systems, a comparison dimension worth naming explicitly rather than treating liberalization as a single democratic or Western phenomenon. The geographic shift of manufacturing toward Asia and Latin America demonstrates that globalization changed the location of production, a distinct process from changes in trade rules and institutions covered above; do not treat these as the same development.
Rights movements and challenges to social hierarchy
Movements for civil rights, women’s rights, Indigenous rights, democracy, labor rights, and LGBTQ+ rights challenged legal and social inequality in many countries during this period, often connecting to the broader human-rights framework that emerged after World War II. The United Nations General Assembly adopted the Universal Declaration of Human Rights in 1948, articulating a broad international language of rights following the experience of World War II, though this declaration functioned as a statement of principle rather than a legally binding or enforceable document in itself. In South Africa, domestic resistance, international activism, sanctions, and political negotiations together contributed to dismantling apartheid and establishing multiracial democracy, connecting directly to the anti-apartheid movement and Mandela’s Rivonia Trial speech covered in the previous unit.
Use this evidence. The combination of domestic resistance and international pressure in ending apartheid demonstrates that this outcome required sustained action operating simultaneously inside and outside the affected state, not one factor alone.
Chronology check. The Universal Declaration of Human Rights, adopted in 1948, is not a legally enforceable world constitution; treating it as such overstates its actual institutional authority, a distinction already noted when this document first appeared earlier in this book.
Rights-based movements challenged assumptions about race, class, gender, and religion through several specific, retrievable named movements, not only the apartheid and UDHR examples above. Global feminism pursued legal, educational, workplace, and political change for women across many countries. Negritude writers asserted Black cultural identity and value directly against colonial-era racial hierarchies. Liberation theology connected Christian religious thought to movements for social and economic justice, especially in Latin America. Women gained voting and office-holding rights at different times across different states during this period, while female literacy and higher-education participation expanded substantially in much of the world. In India, caste-based reservation policies provided another institutional response to entrenched inequality, distinct from South Africa’s anti-apartheid transition. Environmental movements also connected local activism to global concern, including Wangari Maathai’s Green Belt Movement, which organized tree-planting and environmental restoration alongside women’s empowerment in Kenya, while fair-trade activism challenged unequal terms of global commerce more directly.
Use this evidence. Global feminism, Negritude, and liberation theology demonstrate that rights-based challenges to inequality took distinct forms organized around different categories, gender, race, and religiously grounded social justice, across different regions, giving you named evidence beyond apartheid for an LEQ or outside-evidence point on this topic. Wangari Maathai’s Green Belt Movement demonstrates environmental activism connecting directly to women’s empowerment, a useful case for combining two reasoning categories in a single piece of evidence.
Cultural globalization and local adaptation
Film, television, recorded music, advertising, and later digital media accelerated the global circulation of cultural products during this period, creating shared reference points across widely separated populations. This circulation did not simply replace local cultures with a single global culture. Global cultural forms were frequently localized, producing hybrid music, food, fashion, language, and media that blended global and local influences rather than eliminating local distinctiveness entirely. International sports, tourism, and media events created shared global audiences while simultaneously expressing nationalism and local identity, meaning global cultural connection and local or national identity operated together rather than as opposing forces.
Use this evidence. Cultural hybridization demonstrates that global cultural circulation produced genuinely new blended forms, not simple replacement of local culture, a pattern worth comparing to the cultural blending covered earlier in this book’s treatment of trade-network connectivity.
Specific, retrievable evidence matters more than the general concept of "global culture" under exam time pressure. The global circulation of reggae music and Bollywood cinema each carried a specific national and regional culture to worldwide audiences while adapting to and blending with local tastes wherever it spread. The World Cup and the Olympic Games created simultaneously global and national spectacles, drawing worldwide audiences while still organizing competition and identity around individual nations. Multinational consumer brands and online commerce spread shared products and shopping experiences across different societies, evidence of global consumer culture operating alongside, not replacing, more locally rooted cultural forms.
Use this evidence. Reggae, Bollywood, the World Cup, and multinational consumer brands give you named, specific evidence to use directly in an LEQ or outside-evidence point about globalized culture, rather than relying on the general concept of cultural globalization without a retrievable example behind it.
Critiques of globalization and unequal integration
Critics of globalization challenged labor conditions, environmental damage, debt burdens, cultural homogenization, and the concentration of economic power in multinational corporations and international institutions during this period. Postcolonial leaders and movements argued that formal political independence could coexist with continued economic dependence on richer states, a critique connecting directly to the postcolonial economic challenges covered in the previous unit’s treatment of newly independent states. States and movements also used tariffs, local-content rules, censorship, and cultural policy to resist what they perceived as excessive foreign economic or cultural influence, demonstrating that resistance to globalization took economic, political, and cultural forms simultaneously rather than a single unified form.
Use this evidence. The neo-colonial critique demonstrates a direct continuity between decolonization-era concerns about economic dependence and later globalization-era criticism, showing that this concern persisted well beyond the initial period of formal independence covered in the previous unit.
Resistance to economic globalization frequently targeted the International Monetary Fund and World Bank directly, especially where critics connected their loan conditions or structural-adjustment requirements to social costs borne by borrowing states’ populations. Digital globalization could also generate national or local alternatives to global platforms rather than simple worldwide convergence on the same technology: China’s Weibo, a domestically developed social-media platform operating within China’s own distinct regulatory environment, is one example of digital technology spreading globally as a general form while producing locally distinct, nationally regulated platforms rather than one single global digital culture.
Use this evidence. Anti-IMF and World Bank activism demonstrates resistance aimed specifically at international economic institutions, distinct from the cultural or tariff-based resistance covered above. Weibo demonstrates that globalization could spread a general technology, social media, while still producing genuinely different national platforms and regulatory environments, complicating any claim that digital globalization automatically produces one uniform global culture.
United Nations, Bretton Woods institutions, and global governance
The United Nations created forums and agencies for diplomacy, human rights protection, development assistance, decolonization support, and peacekeeping after its founding in 1945, expanding its institutional reach considerably over the following decades. The International Monetary Fund, World Bank, GATT, and later the World Trade Organization institutionalized rules and assistance for monetary stability, development, and trade during this same broader period, while the World Health Organization and other international bodies coordinated surveillance, vaccination, and disease-eradication campaigns across national borders, connecting directly to this unit’s earlier coverage of smallpox eradication. United Nations bodies and resolutions also provided diplomatic venues and legal-political language that anti-colonial movements and newly independent states used directly in pursuing and defending their own political goals.
Use this evidence. The United Nations’ provision of diplomatic venues and legal language for anti-colonial movements demonstrates that international institutions did not simply operate above or apart from decolonization but actively supported specific political movements within that broader process.
Chronology check. The United Nations was founded in 1945, after World War II ended, and should not be treated as a pre-World War I institution. The UN did not single-handedly grant independence to colonies through its 1960 Declaration on Granting Independence to Colonial Countries and Peoples; this resolution provided diplomatic and legal support within a broader decolonization process driven primarily by the colonized movements themselves.
Borders, currencies, trade policy, and state power under globalization
Global exchange intensified after 1900 through faster technology and expanding international institutions, covered throughout this unit, but this intensified exchange did not eliminate unequal power, migration controls, or persistent cultural and political difference among states and regions. States continued to regulate their own borders, currencies, trade policy, welfare systems, security arrangements, and citizenship rules even as global markets, communication networks, and international institutions expanded considerably around and often through these same states. The benefits and costs of global integration were distributed unevenly both among and within countries, creating new opportunities for some populations while leaving others facing continued or even intensified disadvantage.
Comparison dimension. When evaluating continuity and change in globalization, name the specific dimension first: which forms of state control persisted even as global integration intensified, or which populations and regions benefited unevenly from that same integration. A response that lists only intensifying global connection without identifying a genuine, historically defensible continuity in state power or inequality does not meet this unit’s continuity and change task.
