The Industrial Revolution

Britain, about 1750–1850. Everything you need for the assessment: what it was, why it happened in Britain first, the key changes, factories and towns, working and living conditions, and who won and who lost.

1What was the Industrial Revolution?

A period of about 100 years (c. 1750–1850) when Britain changed from a mainly rural, farming country, where goods were made by hand at home (the domestic system), into an urban, industrial country where goods were made by machines in factories (the factory system), powered first by water and then by steam.

It is called a revolution because it changed almost everything: how people worked, where they lived, how fast they could travel and how much things cost. Britain was the first country in the world to industrialise; other countries copied it later.

Key words. Domestic system · factory system · industrialisation · urbanisation (growth of towns) · mass production · capital (money to invest) · entrepreneur (someone who starts a business and takes risks).

2Why did Britain industrialise first?

CauseEvidenceHow it helped
Natural resourcesHuge deposits of coal and iron ore, often close together (Midlands, South Wales, the North). Coal output: c. 5 million tons (1750) → 60+ million (1850).Coal fuelled steam engines and furnaces; iron built machines, bridges and rails. Heavy materials didn't need to travel far.
Agricultural RevolutionEnclosure of open fields; Norfolk four-course rotation (no fallow year); Jethro Tull's seed drill (1701); Robert Bakewell's selective breeding.More food from fewer workers. Population of England & Wales grew from c. 6 million (1750) to 18 million (1850) — giving both workers and customers.
Empire and tradeColonies supplied raw cotton (Americas, India) and sugar; they also bought British goods. The Royal Navy protected trade routes. The slave trade and plantations produced much of this wealth.Raw materials in, finished goods out, profits reinvested in mills.
Money and stabilityStable government (no revolution or invasion); a banking system; rich merchants willing to invest; patents protected inventors.Capital was available to build mills, canals and railways.
TransportAn island with navigable rivers; canals from 1761; later railways.Cheap to move coal, iron and goods.
Inventors and entrepreneursArkwright, Watt, Darby, Stephenson…A culture that rewarded people who built machines and took risks.
Exam tip. The causes link together: coal + steam engines + cheap cotton from the Empire + a growing population to work in and buy from the mills. Say which cause you think mattered most and why.

3Key technological and economic changes

Textiles (cotton) led the way

Steam power

Thomas Newcomen's engine (1712) pumped water out of mines. James Watt improved it (patent 1769; rotary motion in the 1780s) so it was far more efficient and could turn a wheel to drive factory machines. Factories no longer needed to be beside rivers — they could be built in towns, near coal and workers.

Iron and coal

Abraham Darby smelted iron with coke (from coal) instead of charcoal at Coalbrookdale (1709), making iron cheap. His grandson built the world's first Iron Bridge (1779). Cheap iron was needed for machines, engines, bridges and rails.

Transport

Economic changes

The factory system (workers paid wages, working set hours to the clock) and mass production made goods far cheaper. Britain exported them around the world and became "the workshop of the world", shown off at the Great Exhibition of 1851 in the Crystal Palace.

4Factories and industrial towns

People moved from villages to the new towns to find factory work (urbanisation). Push: fewer farm jobs after enclosure and new machinery. Pull: regular wages (usually higher than farm labourers earned), work for women and children, the hope of a better life.

Reforms

6Living conditions

Reforms

The 1848 Public Health Act set up a central Board of Health but was mostly optional, so many towns did nothing — clean water and sewers cost money and ratepayers refused to pay. Real improvement came slowly: Joseph Bazalgette's London sewers (1860s, after the "Great Stink" of 1858) and a compulsory Public Health Act in 1875.

7Impact on different groups

Winners

  • Factory and mine owners — enormous wealth.
  • The middle class (merchants, bankers, engineers, managers, professionals) — new jobs, suburbs away from the smoke, and political power: the 1832 Reform Act gave more middle-class men the vote.
  • Britain as a nation — richest country in the world, cheaper goods, railways.

Losers

  • Skilled hand-workers — handloom weavers' wages collapsed as power looms spread. The Luddites (1811–16) smashed machines in protest; the government made machine-breaking punishable by death (1812).
  • Children — cheap labour, no schooling until the Factory Acts.
  • Farm workers — fewer jobs after enclosure; many left the land.

Mixed

Protest and reform

Wider impacts: Britain became the world's richest nation; towns grew; cheaper goods for everyone — but also smoke, polluted rivers and a huge gap between rich and poor.

8How to answer in the assessment

Example. Point: factory work was dangerous for children. Evidence: scavengers as young as 5 crawled under moving machines, and the 1833 Factory Act banned under-9s from textile mills. Explain: this shows conditions were so bad that Parliament had to step in — but with only four inspectors, the law was hard to enforce, so change was slow.
