State competition & fragmentation

Thesis

Europe’s defining structural feature, from the fall of Rome through the 19th century, was political fragmentation. Roughly 500 polities in 1500, consolidating to 200 by 1700 and a few dozen by 1900 — always, however, a multi-state system in which no single power achieved hegemony for more than a few decades at a time. China, by contrast, spent most of its post-Han history as a unified empire under a single throne (with periodic but relatively brief intervals of fragmentation, most notably the Three Kingdoms 220–280, the Five Dynasties 907–960, and the late-Tang chaos). This single structural difference — sustained fragmentation vs. sustained unification — had cascading consequences that the Great Divergence literature has spent four decades mapping:

Competitive pressure produced innovation. States that did not adopt better military technology, better fiscal machinery, better shipbuilding, or better administrative practices lost wars and were absorbed. Innovation was not a luxury but a survival requirement.
Exit constrained predation. Capital, skilled labour, and entrepreneurs could flee to neighbouring states. Rulers who taxed too heavily or confiscated too aggressively lost the tax base to the rulers who didn’t. This provided a discipline on state extraction that unified China did not face.
Institutional experimentation compounded. With many polities running different political and economic experiments simultaneously, successful innovations (chartered cities, joint-stock companies, parliamentary consent, standing navies, sovereign-debt markets) spread faster than they could have in a single political unit.
Military-fiscal competition built state capacity. The Hundred Years’ War, the Italian Wars, the Thirty Years’ War, the Seven Years’ War, the Napoleonic Wars — each drove European states to develop tax-raising, debt-issuing, bureaucracy-building capacities that far exceeded anything attempted by the Qing. European states became more capable under competitive pressure, not less.

The consequence: Europe was structurally pushed toward the institutions, technologies, and behaviours that eventually produced modern economic growth. China was not. The same dynamic also operated in the smaller European arenas — the Italian Renaissance city-states, the Hanseatic League, the Dutch Republic vs. Spain, the Anglo-French rivalry — at progressively larger scales.

Lead proponents

Eric Jones — The European Miracle (1981) is the foundational book-length statement of the state-competition thesis, and the canonical text for the framework. Jones extended the argument in Growth Recurring (1988) by asking why earlier episodes of pre-modern growth (Song China, the Dutch Republic, classical Greece, late-imperial Rome) stalled rather than breaking through.
Philip Hoffman — Why Did Europe Conquer the World? (2015) takes the thesis further, modelling state-competition-driven military innovation as the proximate cause of Europe’s global military dominance and, indirectly, its economic ascendancy. The military-tournament model is Hoffman’s distinctive contribution: it formalizes the qualitative state-competition story with explicit game-theoretic structure.
Jared Diamond — Guns, Germs, and Steel (1997) argues fragmentation from geography (Europe’s indented coastline, peninsular structure, internal mountain barriers) caused state competition, connecting this position to the geography position. Diamond’s deep-time framing has been broadly influential outside academic economic history.
Patrick O’Brien — while not a dedicated proponent of the state-competition framework as such, O’Brien’s fiscal-military-state work connects the British case (see IR state-capacity position) to the broader European pattern; the British fiscal-military state was a product of sustained competition with France.
David Stasavage — States of Credit: Size, Power, and the Development of European Polities (2011) provides the quantitative-historical case for how the multi-state European system specifically produced the sovereign-credit infrastructure that sustained continued military competition. The smaller European polities (especially the Italian city-states) developed sovereign-credit markets earlier than the larger ones.
Jean Baechler, Walter Scheidel — Baechler’s earlier Origins of Capitalism (1971) and Scheidel’s later Escape from Rome (2019) offer comparative-historical and ancient-history framings of the same fragmentation thesis: Europe’s defining structural condition since the fall of Rome was the failure to reconstitute a Roman-style empire.

The Chinese counterfactual in detail

The state-competition thesis depends heavily on a clean counterfactual case for what happens when an Asian polity did have a fragmented multi-state moment. The empirically interesting comparators are:

Warring States China (475–221 BCE). Massive intellectual and technological flourishing — the Hundred Schools of Thought, foundational developments in metallurgy, agriculture, military technology — followed by Qin unification and a substantial subsequent slowdown of innovation under the unified Han empire. The pattern is structurally compatible with the state-competition framework but at very deep historical time.
Sengoku-era Japan (1467–1600). The “Warring States period” of Japanese history featured rapid military, agricultural, and commercial development under intense daimyō competition, followed by Tokugawa unification (1603) and a substantial peace dividend that shifted innovation from military to civilian channels. Tokugawa Japan still developed substantially — the framework’s predictions for Tokugawa are mixed.
The Indian successor-state period (1707–1818). Mughal authority eroded after Aurangzeb (d. 1707); 18th-century India was a fragmented state-system with Maratha, Mysore (Tipu Sultan), Sikh, Mughal-remnant, Awadh, and other regional powers competing militarily and economically. India did not converge on European-style institutional development across this period. Fragmentation alone is clearly not sufficient.
Song China (960–1279). Continuously threatened by northern steppe powers (Liao, then Jin, then Mongols); fiscal-military-pressed to substantial state-capacity development; experienced a “medieval economic revolution” in commerce, urbanization, paper money, deep-water shipbuilding, gunpowder weaponry, iron production. The Song case is the strongest non-European parallel to the European state-competition trajectory and it stalled with Mongol conquest in 1279.

These comparators support the framework’s broad direction (state competition does correlate with innovation) but complicate the strong-form claim (fragmentation is not sufficient on its own; the specific kind of competition and the specific institutional response matter).

Key arguments

The Chinese counterfactual is powerful. Ming China (1368–1644) temporarily built the world’s largest navy, sent Zheng He’s treasure fleets to the Indian Ocean (1405–1433), and then voluntarily stopped. The decision was a court-politics choice by the unified Ming bureaucracy — the maritime-eunuch faction lost a power struggle to the Confucian-bureaucratic faction in the 1420s–1430s; the records of the voyages were destroyed; subsequent maritime construction was banned at scale (the haijin policies). No fragmented European state-system could have made or enforced such a decision, because the advantages of maritime capacity would have accrued to the defecting state. European maritime exploration, once begun by Portugal and Spain in the late 15th century, was unstoppable precisely because no one could stop it — every other European maritime power had to follow or fall behind.
Competitive arms races drove European military-technical innovation. Hoffman’s quantitative case: tournament-model state competition produced a rapid growth in European artillery effectiveness, ship-of-the-line technology, fortification (the trace italienne), and military organization from ~1400 to 1800 that had no parallel in unified empires. The technology then spilled over into commercial and civilian domains — naval shipbuilding fed merchant shipbuilding; cannon-foundry techniques fed iron metallurgy; military-engineering schools (Mézières from 1748) fed civilian engineering practice.
Exit disciplined fiscal extraction. Jean-Baptiste Colbert, the French finance minister under Louis XIV, explicitly worried that taxing French merchants too heavily would cause them to relocate to Amsterdam, London, or Hamburg. This worry had no Qing analog: Chinese merchants had nowhere to go. The European exit threat kept taxation below confiscatory levels, preserving the tax base.
Small-state experimentation found winning formulas. The Dutch Republic, a federation of commercial provinces, pioneered joint-stock companies (VOC 1602; the world’s first modern joint-stock company), marine insurance, and sovereign bond markets at scale. Once these institutions demonstrated their value, they spread to England, France, and beyond. A single political unit would not have run four simultaneous constitutional experiments in the 17th century. The Italian city-state experiments (Venice’s Council of Ten; Florence’s commercial-republican governance) likewise pioneered governance and finance forms that diffused outward.
Migration of skilled refugees mattered. Huguenot exodus after the 1685 Revocation of the Edict of Nantes (~200,000 French Protestants fled to England, the Netherlands, Prussia, and elsewhere); Dutch Golden-Age immigrants to England post-1688; Jewish finance communities moving between Amsterdam, London, Frankfurt, and Hamburg; English Catholic emigration in the late 16th c. — each wave of political refugees carried technical and commercial skill from intolerant regimes to tolerant ones, compounding the tolerant states’ advantages. Qing China expelled no comparable refugee waves because there was no destination.
The European military-technical lead was self-reinforcing through the colonial era. By 1800, European military technology was sufficient to sustain colonial conquest at scale; the resulting empires generated revenue and resources that further funded military development; the cycle continued through the 19th c. The military-fiscal-imperial loop is the Hoffman framework’s mechanism for translating the intra-European competition into the Europe-vs-Asia divergence.

Key evidence

State-count series. ~500 polities in 1500 Europe → ~200 in 1700 → ~25 in 1900. Consistent fragmentation until the modern nationalism era. Compare Qing China as one polity across the whole period (with some autonomy for tributary border-region khanates and tributary states like Korea).
Hoffman’s military-productivity time series (2015). Ratio of European to Asian military effectiveness rising steadily from ~1500 to ~1900. Largely explained by inter-European competition, not by direct Europe-Asia contact. Hoffman’s data combines artillery effectiveness, ship-of-the-line gun-counts, casualty-ratios in directly observed engagements, and fortification investments.
Zheng He’s treasure fleets and their termination. A single-state policy decision in the 1430s that would have been impossible under fragmentation. The records’ destruction by the Ming court is itself documented in the surviving 16th-century Ming sources.
Colbertian and mercantilist policy archives. Explicit worry about merchant relocation as a discipline on taxation. Repeated across French royal correspondence and contemporary pamphlet literature.
Comparative interest rates. NW European state borrowing costs fell through the 17th–18th centuries as states competed to borrow from a mobile capital pool. Italian city-states 14th c. ~5–8%, Dutch Republic 16th–17th c. ~4%, post-1688 Britain ~3–4%. Qing Chinese state finance, with no capital competition, remained primitive and extracted via direct taxation.
Capital migration patterns. The 1685 Huguenot exodus, the Dutch migration to London post-1688, the Jewish diaspora in financial capitals — these are documented movements with measurable economic consequences in the receiving states.
Stasavage’s representative-body data. NW European parliamentary bodies met more often, took larger fiscal decisions, and persisted across more centuries than their southern or eastern European counterparts; the city-state parliamentary traditions of Italy and the Hanseatic League were the most fiscally sophisticated.

Major critiques

India was also fragmented. Mughal authority had eroded by 1707; 18th-century India was a fragmented state-system with Maratha, Mysore, Sikh, Mughal-remnant, Awadh, and other regional powers competing militarily and economically. Yet India did not converge on European-style institutional development. Fragmentation alone is clearly not sufficient. Defenders argue Indian fragmentation was different in kind (less commercial, more dynastic; no overseas-empire option; with British EIC opportunistically becoming the dominant fragment).
Europe was fragmented and had other things. Fragmentation co-occurred with the Roman legacy, the universal Church, the common Latin intellectual culture, and — later — the printing press. Isolating fragmentation as a causal variable from these co-occurring features is difficult, and the attempt may be fooling ourselves about which was the load-bearing factor.
The Japan case cuts both ways. Tokugawa Japan (1603–1868) was less fragmented than European norms — a single shogun, though with substantial daimyo autonomy — but experienced significant economic and institutional development, including substantial commercialization, urbanization (Edo as the world’s largest city by 1800), proto-industrialization in textiles and ceramics, and the development of an indigenous “Japanese Industrial Revolution” precursor. Sengoku-era Japan (1467–1600) was highly fragmented and was a period of warfare and material advance. The Japanese pattern is hard to fit cleanly into the European-fragmentation-vs-Chinese-unity story.
From the institutional school: fragmentation was a consequence of deeper European structural features (the Roman-Germanic contest, feudal land tenure, chartered cities, Church-vs-Empire rivalry), not a cause. Treating fragmentation as the cause mistakes a downstream outcome for the upstream driver.
Competition can also be destructive. The Thirty Years’ War killed perhaps 30% of the German population in some regions and set Central European economic development back a century. The Napoleonic Wars cost perhaps 6 million lives. The Italian Wars (1494–1559) wrecked the late-Renaissance Italian commercial economies. State competition is not costless; the claim that it net-produced innovation and growth rather than net-destroyed capital and population requires a case-by-case accounting that the strong-form framework rarely does explicitly.
The timing is awkward. European state competition was more intense and more destructive in 1450–1650 than in 1750–1850, but the divergence accelerated in the later period. If state competition is load-bearing, the correlation should arguably go the other way. Defenders point to the lagged-effect pattern (the institutional, fiscal, and technological investments made under earlier military pressure paying off later) but the lag-structure is post-hoc.
Song China is an embarrassment for the strong-form thesis. Song China (960–1279) faced sustained northern-steppe military competition for three centuries, developed substantial state capacity, fiscal-military innovation, paper money, joint-state-merchant maritime trade, the world’s largest urban populations, gunpowder weaponry, and (per Broadberry-Guan-Li) per-capita GDP that may have peaked higher than contemporary European levels. The Song case looks structurally similar to early-modern Europe — military-pressed unified state generating innovation — without producing a Great Divergence. Mongol conquest in 1279 ended the trajectory; subsequent Yuan and early Ming did not recover it. The case is the principal reason most modern proponents hold the weak form (fragmentation as enabling, not sole cause) rather than the strong form.
The post-1815 European peace. The 19th-c. European concert system substantially reduced inter-state warfare for a century; if the framework predicts that competition drives innovation, the 19th c. should have been a stagnant century. Instead it was the period of greatest European economic-technological acceleration. Defenders argue commercial competition replaced military competition as the discipline; this is plausible but again post-hoc.

Status

Mainstream. The state-competition thesis has been part of every serious GD account since Jones 1981 and is rarely directly challenged. It is usually one of 2–3 factors in a stacked explanation rather than the primary cause. Hoffman’s military-productivity work has given it a new quantitative footing in the 2010s. The strong form — that fragmentation primarily caused the divergence — is held by fewer than the weak form: that fragmentation was a significant enabler of the institutional, fiscal, and technological changes that did cause the divergence. The most active contemporary work in the framework is at the intersection with comparative public-finance history (Stasavage, Dincecco) and at the integration with the European institutional advantage position — two frames that can be hard to disentangle empirically.
