Historical Context & Motivation
The twentieth century witnessed an unprecedented acceleration in the pace and scope of global interconnection, yet the forces driving this transformation were not entirely new. Trade networks, cultural exchange, and imperial expansion had linked distant regions for centuries—from the Silk Roads to the Columbian Exchange—but the period after 1900 introduced qualitatively different mechanisms of integration. Globalization in the modern sense refers to the intensification of worldwide social relations and interdependence such that local happenings are shaped by events occurring many miles away and vice versa. Understanding how this process simultaneously generates change and preserves continuity is essential for interpreting the modern world.
The AP World History framework organizes analysis of the period from 1900 to the present around a central historiographical skill: the ability to identify and explain patterns of continuity and change over time. This skill requires students to move beyond simple narratives of progress or decline, instead recognizing that historical processes operate unevenly across regions, social classes, and cultural domains. A single phenomenon—such as the spread of digital technology—can disrupt traditional economic structures while reinforcing existing power hierarchies.
These milestones frame the central question this lesson addresses: How do we systematically analyze the ways in which globalization has transformed political structures, economic systems, cultural practices, and social hierarchies—while simultaneously recognizing which patterns have persisted, adapted, or resisted change? Mastering this analytical framework is essential for both the multiple-choice and free-response portions of the AP exam.
Core Principles of Continuity and Change
Analyzing continuity and change requires a structured approach that goes beyond identifying isolated events. Historians examine turning points (moments when the trajectory of history shifts significantly), structural continuities (deep patterns that persist across turning points), and processes of transformation (the mechanisms through which change occurs). The following core principles provide the analytical scaffolding for the globalization era.
Uneven Integration
Hybridization vs. Homogenization
Persistent Hierarchies
State Adaptation
Resistance & Backlash
Visual Explanation: Forces of Continuity and Change
The following diagram maps the dynamic interplay between forces that drive historical change and structures that maintain continuity in the globalized world. Each domain—political, economic, cultural, and social—experiences both transformation and persistence simultaneously. The arrows represent causal connections between globalizing forces and responses.
Notice that the diagram does not treat change and continuity as opposites locked in a zero-sum struggle. Rather, they are co-constitutive: change operates through existing structures, and continuities adapt to new circumstances. The Chinese Communist Party's embrace of market economics while maintaining one-party authoritarian rule exemplifies this dynamic: the economic system has transformed dramatically, but the political structure has persisted and even consolidated power through new surveillance technologies.
How Globalization Drives Change While Preserving Continuity
Political Transformations and Continuities
The political landscape since 1900 has undergone dramatic structural transformations. The most consequential was decolonization, which between 1945 and 1975 created dozens of new sovereign states across Asia, Africa, the Middle East, and the Caribbean. This represented a fundamental change in the global political order: the number of independent states in the United Nations grew from 51 in 1945 to over 150 by 1980. Yet the borders drawn by colonial powers largely persisted, as did the economic relationships that tied former colonies to metropoles. Neocolonialism—the continuation of economic and cultural dependency after formal political independence—illustrates how structural continuity operates beneath the surface of revolutionary change.
Economic Transformations and Continuities
The global economy has shifted from industrial capitalism centered in Europe and North America to a multipolar system in which East Asian economies—particularly China, Japan, and South Korea—have become manufacturing powerhouses. The rise of multinational corporations (MNCs) and global supply chains represents a genuine transformation in how goods are produced and distributed. However, the fundamental pattern of core-periphery economic relationships has proven remarkably durable. Countries that export raw materials and import finished goods—a pattern established during the colonial era—often continue to do so, even as the identity of the dominant core shifts.
Cultural Transformations and Continuities
Culturally, globalization has produced what scholars call glocalization—the process by which global cultural products are adapted to local contexts. McDonald's serves McAloo Tikki burgers in India; K-pop draws on American pop structures while embedding Korean musical and aesthetic traditions. Meanwhile, religious identity has proven to be one of the most resilient continuities of the modern era. Far from secularization sweeping the globe as mid-twentieth-century modernization theorists predicted, religious movements—from evangelical Christianity in Latin America to political Islam in the Middle East—have intensified, often in direct response to the dislocations caused by globalization.
Domains of Continuity and Change in Detail
To write effective AP essays, students must be able to identify specific examples of continuity and change across four major domains: political, economic, cultural, and social. The table below provides a systematic framework for organizing evidence across these domains, with concrete examples drawn from the 1900-to-present period.
| Domain | Key Changes (1900–present) | Key Continuities (1900–present) |
|---|---|---|
| Political | Decolonization; rise of international organizations (UN, EU); spread of democratic institutions; end of Cold War bipolarity | Nation-state remains dominant political unit; great-power competition persists; authoritarian governance adapts (China, Russia); borders drawn by colonial powers endure |
| Economic | Rise of MNCs and global supply chains; shift from gold standard to fiat currencies; emergence of service/knowledge economies; Asian economic miracles | Core-periphery dynamics; wealth inequality within and between nations; dependence on fossil fuels; labor exploitation in export-processing zones |
| Cultural | Mass media and internet create global popular culture; glocalization; spread of English as a lingua franca; secularization in parts of Europe | Religious identity remains central worldwide; local languages persist despite English dominance; indigenous cultural revitalization movements; tension between tradition and modernity |
| Social | Women's suffrage movements; civil rights advances; LGBTQ+ rights expansion; urbanization and growth of megacities | Patriarchal structures in family and workplace; racial and ethnic discrimination; class-based social stratification; rural-urban divides |
| Environmental | Climate change as a global crisis; environmental treaties (Kyoto, Paris); Green Revolution transforms agriculture; nuclear energy and renewables | Extractive relationship with nature persists; deforestation continues; reliance on fossil fuels despite alternatives; environmental costs disproportionately borne by Global South |
Worked Example: Analyzing Continuity and Change
The following worked example demonstrates how to construct a thesis and supporting argument for a typical AP World History CCOT prompt. This step-by-step process models the analytical thinking required on the free-response section of the exam.
Competing Perspectives on Globalization
Historians and social scientists disagree about whether globalization has been primarily beneficial or harmful, and whether the continuities of the modern era represent resilience or injustice. Understanding these competing perspectives is essential for evaluating primary sources and constructing nuanced arguments on the AP exam.
| Perspective | Core Argument | Limitations |
|---|---|---|
| Modernization Theory | All societies follow a linear path from "traditional" to "modern"; globalization accelerates this beneficial transition through technology transfer, trade, and institutional reform. | Assumes Western development as normative; ignores structural barriers to development; fails to explain why some integrated economies remain poor. |
| Dependency / World-Systems Theory | The global economy is structured to benefit core nations at the expense of periphery; globalization perpetuates exploitation through unequal exchange and institutional control. | Can be overly deterministic; struggles to explain the economic rise of former periphery nations like South Korea and China; downplays local agency. |
| Postcolonial Theory | Colonial legacies—cultural, psychological, and institutional—continue to shape identities and power relations; globalization is a continuation of colonialism by other means. | Can overemphasize cultural dimensions at the expense of material analysis; risk of essentializing non-Western cultures as uniformly victimized. |
| Neoliberal Globalism | Free markets, deregulation, and reduced state intervention maximize efficiency and growth for all participants; globalization lifts all boats. | Increasing evidence of rising inequality within nations; financial crises (2008) exposed systemic risks; environmental externalities ignored. |
Continuity and Change in the Twenty-First Century
The twenty-first century has introduced new variables into the continuity-and-change dynamic while intensifying existing patterns. The table below contrasts late-twentieth-century globalization with emerging twenty-first-century trends, highlighting how the analytical framework developed in this lesson applies to contemporary events.
| Dimension | Late 20th Century (1980–2000) | 21st Century (2001–present) |
|---|---|---|
| Economic Integration | Expansion of free trade (NAFTA, EU single market, WTO); Washington Consensus drives structural adjustment | Rise of China as economic superpower; Belt and Road Initiative; trade wars and protectionist backlash; reshoring and supply chain nationalism post-COVID |
| Technology | Personal computers, early internet, mobile phones begin to spread | Social media, artificial intelligence, cryptocurrency, and surveillance technology create new modes of both connection and control |
| Political Order | Unipolar moment (U.S. hegemony); "end of history" thesis; spread of liberal democracy | Multipolar competition (U.S., China, EU, India); democratic backsliding in Hungary, Turkey, Brazil; populist nationalism |
| Social Movements | Anti-apartheid movement; fall of communism in Eastern Europe; environmental awareness grows | Arab Spring; Black Lives Matter; #MeToo; Fridays for Future—digitally organized, globally networked movements |
| Environmental | Ozone layer depletion addressed (Montreal Protocol); climate change gains scientific consensus | Climate crisis intensifies; Paris Agreement (2015); renewable energy expansion; but fossil fuel dependence continues (continuity) |
What emerges from this comparison is that the twenty-first century does not represent a clean break from the late twentieth century but rather an intensification and complication of existing trends. The COVID-19 pandemic (2020–2023) is perhaps the most revealing recent case study: it exposed the fragility of global supply chains (change in economic confidence) while reinforcing the primacy of nation-states as the units responsible for public health responses (continuity of state sovereignty). Looking forward, students should expect AP exam questions that test the ability to apply continuity-and-change analysis to events like the pandemic, the war in Ukraine, or the rise of artificial intelligence.
Practice Problems
Lesson Summary
The period from 1900 to the present has been defined by the intensification of globalization—the deepening of economic, political, cultural, and social interconnections across national boundaries. Key transformations include decolonization, the creation of international institutions (UN, IMF, WTO), the end of the Cold War, the digital revolution, and the expansion of social movements for gender, racial, and environmental justice. These developments reshaped the global order in profound ways.
Yet equally important are the structural continuities that have persisted: core-periphery economic inequality, the dominance of the nation-state as the primary political unit, the resilience of religious and ethnic identities, and the persistence of patriarchal gender hierarchies. Effective AP analysis uses the continuity and change over time framework to explain not merely what changed, but why some patterns transformed while others adapted and endured—recognizing that change and continuity are co-constitutive processes, not opposites.
