The age of movement: Mass migration in a fragmented world

Daniel Shin

Massive migration has been one of the central forces shaping human history. Long before modern borders and passports, people moved in response to climate shifts, war, trade, ambition and survival. From the spread of early humans out of Africa to the vast imperial movements of the early modern world, migration has never been an exception to history — it has been its engine. Understanding this long arc matters today, especially in an era marked by renewed nationalism, intensifying geopolitical rivalry and debates over U.S. leadership of the global order, as Secretary of State, Marco Rubio implied at the Munich Security Conference.

One of the most transformative waves of migration was the series of movements that contributed to the fall of the Western Roman Empire by Germanic tribes. The collapse of Roman authority did not end civilization; rather, it reshaped Europe’s political and cultural landscape. Migration here was not simply displacement. It was re-foundation.

Centuries later, there was another massive migration. European expansion into the Americas after 1492 triggered the largest intercontinental movement of people in history to that date. Early settlers, followed by colonists, established new societies across the Atlantic. The forced migration of millions of Africans through the transatlantic slave trade added another tragic and foundational dimension. The modern states of the Americas cannot be understood without recognizing that they were built through migration.

The 19th and early 20th centuries witnessed another extraordinary demographic shift. Tens of millions of Europeans emigrated to the U.S., Latin America, Canada and Australia. The U.S. in particular became a nation defined by immigration. Industrial growth in cities like New York and Chicago depended on waves of European migrants. The Statue of Liberty symbolized a national identity rooted not in bloodline but in civic aspiration.

The 20th century added further layers, including the displacement of millions during the two world wars, the partition of India in 1947, postcolonial migrations from Africa and South Asia to Europe and the creation of Israel. After World War II, institutions such as the United Nations were established to manage the global consequences of war and displacement, embedding migration within a new international legal framework of refugees and human rights.

After the Cold War, globalization accelerated under institutions like the World Trade Organization. Markets, capital and information flowed across borders with unprecedented speed. Yet the movement of people remained politically sensitive. In the U.S. and Europe, nationalist movements increasingly framed migration as a threat to sovereignty and identity, challenging the liberal assumptions that underpinned the post-1945 order.

Recently, a new dimension of state-directed global movement has emerged through China’s rise. Under Xi Jinping’s leadership, China launched the Belt and Road Initiative (BRI), a vast network of infrastructure projects spanning Asia, Africa, Europe and parts of Latin America. While framed primarily as an economic and connectivity strategy — building ports, railways, highways, and digital networks — the BRI also carries demographic implications.

Chinese companies operating abroad often bring their people to construct and manage projects. Over time, commercial hubs, industrial parks and logistics centers create small but growing Chinese diasporic communities in participating countries. In some regions, particularly parts of Southeast Asia and Africa, Chinese migration linked to infrastructure and investment has become a visible feature of local economies. Though not comparable in scale to the mass European migrations of the 19th century, this outward movement reflects a strategic blending of capital, labor and geopolitical influence.

Critics argue that such projects extend China’s political influence, embedding long-term economic dependence and reshaping regional alignments. Supporters counter that the BRI provides much-needed infrastructure and development financing where Western-led institutions have been slow or restrictive. Either way, the initiative illustrates that migration today is not only a spontaneous human response to hardship or opportunity. It can also be tied to state strategy and global power competition.

Thus, migration now sits at the intersection of nationalism and great power rivalry. The U.S. has long portrayed itself as the architect of a rules-based international order, while China promotes alternative frameworks centered on sovereignty and development partnerships. As both powers compete for influence, migrants become politically charged.

Why does this matter now? Demographic pressures, economic inequality and climate change will continue to push people across borders. Aging societies require labor. Developing societies seek opportunity. Meanwhile, state-led initiatives like the BRI show how migration can accompany strategic expansion.

History suggests that nations are not static entities but products of movement and intermingling. Nationalism tends to imagine a stable and homogeneous past. Migration reveals that such stability is often a myth. Massive migration is not an anomaly but a recurring condition of human civilization. In a world where both nationalist politics and competing global orders seek to shape borders and influence, the central question remains the same: how to manage migration without denying the fundamental human impulse and necessity to move.
