Primitive Capital Accumulation
The Marxist concept that the origins of capitalism were set in motion during feudalism through the dispossession of the peasant class (creating a free, propertyless working class) and mercantile capital extracted from colonial trading systems.
Robot
A form of feudal tribute consisting of compulsory unfree labour services demanded by landlords from serfs, which varied depending on market opportunities alongside tribute in kind or money.
Glorious Revolution of 1688
The political transformation in England that established parliamentary government, constrained the Crown's power, secured property rights, and expanded fiscal borrowing capacity.
North-Weingast Hypothesis (1989)
The institutional theory proposing that modern economic growth was unlocked after 1688 because Parliament gained control over taxes and monopolies, the Crown could no longer arbitrarily remove judges, and public debt was guaranteed by Parliament.

The centralized early modern Western state model characterized by a monopoly on violence, permanent conflict-regulating institutions, and effective administrative capacity to tax and fund armed forces.

Peace of Westphalia (1648) Political Map
The historical map illustrating early modern European state consolidation along the Atlantic and North Sea coastlines (e.g., England, France, Spain, Portugal, Dutch Republic), while Central Europe (Germany and Italy) remained fragmented until the 1860s.
Weber's Protestant Ethic Thesis
Max Weber's argument that the Rise of the West was driven by Western rationality originating from Protestant theology, an interpretation contested by historical evidence showing rising poverty in Protestant areas.

A unique craft skill-formation institution regulated by urban guilds in England that fostered competition by placing apprentices with top masters, integrated rural youth into London, and offered social mobility across classes.
The Malthusian Trap
A self-equilibrating pre-industrial demographic mechanism where any technological or income gain is eventually eroded by population growth, returning per capita living standards to subsistence level.

Malthusian Preindustrial Model
The formal demographic model where rising income per person increases birth rates and lowers death rates, but subsequent population growth depresses wages due to diminishing marginal productivity of labour on fixed land.

Real Farm Wages vs. Population Dynamics (1200–1800)
Historical evidence from England demonstrating the Malthusian inverse relationship: the demographic collapse following the 1340s Black Death caused real wages to peak, while population recovery after 1500 depressed real wages back to subsistence.
European Marriage Pattern (EMP)
A demographic regime described by János Hajnal (1965) in Northwestern Europe characterized by late female marriage (24–26 years), a high proportion of permanently unmarried women (10–25%), and low illegitimacy rates (3–4%).

Mineral-Fuel Economy
An economic system powered by subsoil fossil energy (coal) and manufactured mineral inputs (iron, steel), escaping the strict biological land-surface constraints of traditional organic economies.
Timber Crisis Hypothesis (Nef 1932)
John Nef's theory that deforestation in 16th- and 17th-century Britain drove up wood prices, compelling Britain to transition to coal; challenged by Allen, who showed real wood prices rose primarily due to London's urban growth after 1650.

London's Demographic Surge (1300s–1800)

Power Loom (Cartwright, 1784)
Edmund Cartwright's mechanical loom, which automated the weaving process using water or steam power, fully resolving the weaving bottleneck by the 1830s.

Trajectory of Micro-Improvements
The technical trajectory showing how steady incremental improvements shift unit factor requirements downward from technique T to X, making initially British-biased technologies eventually profitable in low-wage countries.

European Coal Deposits and Early Follower Regions
The geographical distribution of bituminous and lignite coal deposits across Europe, illustrating why early industrialization on the Continent was localized to coal-rich regions like Wallonia, the Ruhr, and Silesia.

Raw Cotton Processed in Cotton Spinning (1840s vs. 1900s)
Comparative industrial consumption data demonstrating the catch-up of latecomers: UK cotton processing rose from 192,000 to 869,000 tons, but was surpassed by the United States (1,110,000 tons) by the 1900s.

Urban Penalty (Early Growth Paradox)
The phenomenon during the early Industrial Revolution where aggregate productivity rose without an immediate increase in living standards, as workers suffered from urban overcrowding, poor sanitation, infectious disease, and stagnant real wages.
Deindustrialisation of India
The economic reversal whereby British factory mechanization reduced spinning and weaving production costs by three-quarters between 1800 and 1826, devastating Indian handicraft cotton production and turning India from a major textile exporter into an exporter of raw cotton.

The deep integration of international markets through commodity trade, capital mobility, mass migration, and knowledge diffusion, evidenced empirically by international price convergence across national borders between 1870 and 1914.
Classical Gold Standard
The international monetary system prevailing from the 1870s to 1914 where national currencies had fixed exchange rates tied directly to gold, reducing exchange-rate uncertainty and facilitating trade.

An artificial waterway opened in Egypt in 1869 that shortened the maritime travel distance between Britain and India by 40%, lowering transport costs for steam shipping to Asia.
Core-to-Periphery Capital Flows
The large-scale financial export of accumulated European savings between 1870 and 1914 (Britain alone exported 4% of its GDP annually) to build railways, ports, and resource-extractive infrastructure in resource-rich frontier economies.

Home Wage and Emigration Rate Model
The migration model from Daudin et al. (2010) showing that outward shifts in the emigration curve (due to cheaper transport and migrant networks) allowed workers to finance migration at higher domestic wage levels.
