The Great Divergence is the dramatic widening of wealth and power between Western Europe and the rest of the world that accelerated from roughly the 1800s onward. By the mid-19th century, a laborer in London earned several times more than a laborer in Beijing or Delhi, and European nations controlled vast global empires. How and why this gap opened up is one of the most debated questions in economic history, with scholars disagreeing not just on the causes but on when the divergence actually began.
Where the Term Comes From
The phrase was popularized by historian Kenneth Pomeranz in his 2000 book The Great Divergence: China, Europe, and the Making of the Modern World Economy. Pomeranz argued that as late as 1750, the most advanced regions of China, particularly the Yangtze Delta, were roughly comparable to England and the Netherlands in terms of living standards, life expectancy, and market sophistication. In his telling, the split happened late and fast, driven largely by two lucky breaks for Europe: easy access to coal deposits and the exploitation of New World resources through colonialism. Before Pomeranz, many Western historians had assumed Europe’s advantages stretched back centuries. His book forced a rethinking of that timeline.
The “Late” vs. “Early” Divergence Debate
Pomeranz belongs to what’s often called the California School of historians, who emphasize similarities between Europe and Asia well into the early modern period. Their core claim is that nothing inherent in European culture or institutions made industrialization inevitable. It was contingent, shaped by geography and empire as much as by ideas.
On the other side, scholars like David Landes argued that Western Europe was on a distinctive path as early as 1000 CE. Landes didn’t claim medieval Europe was wealthier than Song Dynasty China or the Islamic world in raw economic output. His argument was subtler: that sometime during the medieval or early modern era, Europe “took a path that set it decisively apart from other civilizations.” That path included things like competitive fragmentation among states, a culture of mechanical tinkering, and legal frameworks that rewarded individual enterprise. For Landes, the Industrial Revolution wasn’t a lucky accident. It was the culmination of centuries of incremental advantages.
This debate isn’t purely academic. If the divergence happened late and by accident, it implies that any region could have industrialized first given the right circumstances. If it happened early and by design, it suggests deeper structural or cultural forces were at work, a conclusion with very different implications for how developing economies think about growth today.
The Role of Institutions and Property Rights
A major school of thought, often called neo-institutionalism, argues that Europe’s advantage came from political and legal structures that protected property, enforced contracts, and limited the power of rulers to seize wealth. The classic version of this argument points to England’s Glorious Revolution of 1688, when Parliament established a constitutional monarchy. With the king’s power checked, property owners felt secure enough to invest, lend, and innovate. Banks and capital markets followed.
More recent research has complicated this story. Economists have shown that the Glorious Revolution wasn’t quite the clean break it’s often made out to be, and that property rights varied enormously across Europe long before 1688. One line of research traces these differences back to medieval land ownership patterns. In regions where a large landlord class held most of the land, economic development followed a different trajectory than in regions where property was more widely distributed. As populations recovered from the devastation of the Black Death in the 14th century, the size and power of the landlord class shaped whether ordinary people could accumulate wealth, move freely, and respond to market opportunities. In other words, the institutional roots of the divergence may stretch much further back than a single English political settlement.
Coal, Colonies, and Industrial Takeoff
Even scholars who emphasize institutions acknowledge that the divergence truly exploded with industrialization. England’s coalfields were unusually close to its population centers and waterways, making coal cheap to extract and transport. China had vast coal reserves too, but they were concentrated far from its economic heartland in the south and east. This mattered enormously once steam engines made coal the foundation of factory production, rail transport, and naval power.
Colonialism provided the other critical ingredient. The wealth extracted from the Americas, including silver, sugar, cotton, and enslaved labor, gave European economies access to raw materials and markets on a scale no Asian power could match in the 18th century. Pomeranz argued that without New World resources relieving pressure on European land, England would have faced the same ecological constraints that slowed growth in the Yangtze Delta. European workers could be shifted into factories because colonial plantations supplied food and fiber that would otherwise have required domestic farmland.
What the Gap Actually Looked Like
The numbers are staggering when you zoom out. In 1500, per capita income differences between the richest and poorest regions of the world were modest, perhaps a ratio of two or three to one. By 1900, the gap between industrialized Western Europe and much of Asia and Africa had widened to roughly ten to one or more. Life expectancy in England doubled over the 19th century. Urbanization accelerated. Literacy became near-universal. Meanwhile, regions drawn into the global economy as commodity exporters or colonial subjects often saw their existing industries destroyed by cheap European manufactured goods.
China’s trajectory illustrates the reversal sharply. In 1820, China still accounted for roughly a third of global economic output. By 1950, that share had collapsed to under five percent. India followed a similar arc. These declines weren’t simply about Europe growing faster. Colonial extraction, forced trade agreements, and the disruption of existing economic systems actively dismantled wealth in much of Asia and Africa.
The Great Convergence
Since the late 20th century, the Great Divergence has been partially reversing. Rapid industrialization in East Asia, beginning with Japan and followed by South Korea, Taiwan, and especially China, has narrowed the income gap dramatically. China’s share of global GDP has climbed back toward levels not seen since the early 1800s. India and several Southeast Asian economies are on similar, if slower, trajectories.
This ongoing “Great Convergence” has itself reshaped the debate. If non-Western economies can industrialize rapidly once they adopt certain institutions and technologies, it suggests the divergence was never about permanent civilizational differences. It was about a specific set of historical conditions, some chosen and some accidental, that gave one part of the world a temporary but devastating head start.
