5.3 Industrialization Begins

Verified for the 2025 AP World History: Modern examCitation:

The Industrial Revolution marked a pivotal shift in global economic production, driven by human innovation and access to natural resources. Beginning in Great Britain in the mid-18th century and spreading to places like France, Germany, and the United States, industrialization transformed societies by concentrating production, introducing new technologies, and fundamentally altering the relationship between humans and the environment.

Environmental and Economic Causes of Industrialization

Industrialization would not have been possible without favorable environmental conditions and economic incentives. Several interrelated factors helped launch this revolution in production:

  • Proximity to waterways (rivers and canals) provided energy and cheap transportation.
  • Abundant natural resources, especially coal, iron, and timber, supplied the raw materials for industry.
  • Improved agricultural productivity (from the Agricultural Revolution) freed labor for factories.
  • Legal protections for private property encouraged innovation and investment.
  • Urbanization created concentrated labor forces.
  • Access to foreign markets and resources through colonies enabled capital accumulation.
  • Capitalism and profit motives fueled entrepreneurial efforts and factory growth.


Geography Matters: Britain’s location atop major coal deposits and its expansive network of navigable rivers gave it a critical edge. The ability to extract and transport fuel and materials easily helped power early factories.

Agricultural Advances and Labor Shifts

Increased agricultural efficiency meant fewer workers were needed on farms, leading to rural-to-urban migration. New methods like crop rotation, the seed drill, and the widespread cultivation of the potato improved food supply and population growth.


The Enclosure Movement in Britain forced small farmers off common lands, concentrating land ownership and pushing rural populations into growing industrial cities.

Colonial Wealth and Capital Accumulation

European powers like Britain used their colonies to extract both raw materials (such as cotton, sugar, and rubber) and wealth, which were then reinvested in industrial development.

  • Colonies served as sources of raw materials and new markets for manufactured goods.
  • The accumulation of capital from overseas trade enabled investment in new machinery, infrastructure, and factories.

The Factory System and Specialization of Labor

The hallmark of industrialization was the rise of the factory system—a model where goods were produced under one roof, powered by machines and organized labor.

Centralized Production

Prior to industrialization, goods were often made by hand in the home (the cottage industry). Factories centralized and mechanized this process, boosting efficiency.

  • Workers were brought into a single location, often near water for power.
  • Production was mechanized, increasing both volume and speed.
  • Cities grew rapidly as people moved closer to factory jobs.

Specialization of Labor

To maximize productivity, the division of labor was implemented. Instead of crafting entire products, workers focused on one repetitive task—a key feature of assembly line production.

Pre-Industrial LaborIndustrial Labor (Factory System)
Skilled artisansUnskilled factory workers
Home-based (cottage)Centralized in factories
Flexible work hoursRigid schedules and time discipline
Full-product craftsmanshipRepetitive, task-specific specialization


Efficiency vs. Autonomy: Specialization of labor increased productivity but often stripped workers of craftsmanship and independence, making them dependent on factory jobs.

Broader Social and Economic Effects

The Industrial Revolution created winners and losers. On one hand, it spurred the rise of a middle class, consumer goods, and urban growth. On the other, it introduced harsh working conditions, environmental degradation, and growing economic inequality.

  • Middle Class Growth: Factory owners, merchants, and professionals gained wealth and social mobility.
  • Working Class Hardships: Long hours, low wages, and unsafe conditions defined factory life.
  • Urbanization: Rapid city growth led to overcrowding, poor sanitation, and public health issues.
  • Environmental Impact: Coal-burning and industrial waste drastically altered the natural environment.

Key Terms to Review (27)

Access to Foreign Resources: Access to foreign resources refers to the ability of a nation or region to obtain raw materials, goods, and technologies from outside its own borders. This access was crucial during periods of industrialization, as it enabled countries to fuel their economic growth and enhance their manufacturing capabilities by importing essential commodities and innovations not available domestically.
Assembly Line: An assembly line is a manufacturing process in which individual parts of a product are assembled in a sequential manner along a conveyor belt or production line, allowing for mass production and increased efficiency. This method revolutionized the manufacturing industry by enabling faster production rates and lowering costs, significantly impacting the economy and labor practices during industrialization and later in global conflicts.
Britain: Britain refers to the island nation that became a global powerhouse during the Industrial Revolution, particularly in the 18th and 19th centuries. Its vast maritime empire and innovative industrial practices positioned it as a leader in economic, political, and cultural spheres, influencing global dynamics and interactions across different regions.
Capitalism: Capitalism is an economic system characterized by private ownership of the means of production, where goods and services are produced for profit in a competitive marketplace. This system encourages innovation, consumer choice, and investment, shaping social and economic structures throughout history.
Coal: Coal is a combustible black or brownish-black sedimentary rock primarily composed of carbon, used extensively as a fuel source during the Industrial Revolution and beyond. Its importance grew as industrialization began, driving energy production and powering steam engines, which in turn led to massive economic and social changes.
Cotton Gin: The cotton gin is a mechanical device invented by Eli Whitney in 1793 that quickly separates cotton fibers from their seeds. This invention revolutionized the cotton industry by significantly increasing the speed of cotton processing and making it more profitable, which in turn fueled the growth of the plantation system in the American South and contributed to the broader patterns of industrialization and technological advancement during this period.
Crop Rotation: Crop rotation is an agricultural practice that involves alternating the types of crops grown on a particular piece of land over successive seasons. This method helps improve soil fertility, control pests and diseases, and optimize the use of nutrients, leading to more sustainable farming practices. Its significance is particularly noted during periods of early industrialization and transformations in agricultural techniques from 1450 to 1750.
Enclosure Act: The Enclosure Act refers to a series of laws passed in England between the 18th and 19th centuries that consolidated small landholdings into larger farms. This process transformed communal lands into privately owned plots, which were fenced off and cultivated more efficiently. The Enclosure Acts played a significant role in the agricultural revolution, leading to increased productivity and setting the stage for industrialization as displaced rural workers moved to cities in search of employment.
Factory System: The Factory System refers to a method of manufacturing that emerged during the Industrial Revolution, characterized by the centralized production of goods in large-scale factories.
