British Period Study: The Impact of Empire on Britain, c.1688–c.1730

What you'll learn

This revision guide covers how British imperial expansion between c.1688–c.1730 transformed Britain economically, socially and politically. You'll understand the growth of overseas trade, the development of the transatlantic slave trade, and how colonial wealth influenced British society. This period follows the Glorious Revolution and examines Britain's emergence as a major imperial and commercial power.

Key terms and definitions

Triangular Trade — the three-way trading system linking Britain, West Africa and the Caribbean/Americas, involving manufactured goods, enslaved Africans, and colonial products like sugar and tobacco

Plantations — large agricultural estates in the Caribbean and American colonies that produced cash crops like sugar, tobacco and cotton using enslaved labour

Navigation Acts — laws passed from 1651 onwards requiring colonial goods to be shipped in English vessels and through English ports, ensuring Britain controlled colonial trade

Royal African Company — chartered monopoly company (1660–1752) initially controlling English trade with West Africa, particularly in enslaved people, before losing its monopoly in 1698

Joint-stock company — business organisation where investors purchased shares to fund expensive overseas ventures like the East India Company, spreading financial risk

Mercantilism — economic theory that a nation's wealth depended on accumulating gold and silver through a favourable balance of trade, with more exports than imports

Re-export trade — the practice of importing colonial goods into Britain then selling them to European markets at profit, making Britain a commercial hub

Middling sort — the emerging social class of merchants, professionals and successful tradesmen who benefited from colonial trade but ranked below the gentry

Core concepts

The growth of overseas trade and its economic impact

Between 1688 and 1730, British overseas trade expanded dramatically. The value of imports from the colonies increased from approximately £800,000 in 1700 to over £1.5 million by 1730.

Key trading regions:

• North America: tobacco, timber, furs, rice
• Caribbean: sugar, molasses, rum
• East Indies: spices, silk, cotton textiles
• West Africa: gold, ivory, enslaved people

The re-export trade became increasingly profitable. Britain imported raw materials and exotic goods, then processed and sold them throughout Europe. Sugar arrived from the Caribbean, was refined in British ports, then exported to continental markets. This generated substantial customs revenue for the government and employment in port cities.

Economic consequences:

• Port cities expanded rapidly—Bristol, Liverpool and Glasgow grew wealthy from colonial trade
• Manufacturing industries developed to supply colonial markets with textiles, metalware and other goods
• Banking and insurance sectors expanded to finance overseas ventures
• Government revenue from customs duties increased, funding the navy and wars

The Navigation Acts ensured colonial trade benefited Britain exclusively. Colonies could only trade with Britain or other British colonies, using British ships. This created a protected market for British merchants and manufacturers while preventing foreign competition.

The transatlantic slave trade and plantation economies

The period 1688–1730 saw the transatlantic slave trade become central to British imperial economics. After the Royal African Company lost its monopoly in 1698, independent merchants entered the trade, dramatically increasing the number of enslaved Africans transported.

Scale of the trade:

• Between 1690 and 1730, British traders transported approximately 400,000 enslaved Africans
• By 1730, Britain dominated the transatlantic slave trade, surpassing Portugal and the Netherlands
• Enslaved people were primarily taken from West African coastal regions including modern-day Ghana, Nigeria and Angola

The Triangular Trade system:

1. Britain to Africa: Ships carried manufactured goods (textiles, guns, alcohol, metal goods) to exchange for enslaved people
2. Africa to the Americas (the Middle Passage): Enslaved Africans were transported in horrific conditions to Caribbean and American colonies
3. Americas to Britain: Ships returned with colonial products—sugar, tobacco, rum, cotton

Plantation agriculture:

Caribbean islands like Jamaica, Barbados and the Leeward Islands developed plantation systems dependent on enslaved labour. Sugar production was particularly profitable but extremely labour-intensive. Enslaved people faced brutal conditions, high mortality rates, and systematic violence.

The plantation system generated enormous wealth for British plantation owners, many of whom returned to Britain and purchased estates, gaining political influence as "absentee landlords."

Changes in British society and culture

Colonial trade created new forms of wealth and consumption that transformed British society between 1688 and 1730.

The rise of the middling sort:

Merchants, shipowners, insurers, brokers and colonial agents accumulated wealth from imperial trade. This middling sort challenged traditional social hierarchies based solely on land ownership. Successful merchants purchased country estates and intermarried with the gentry, using colonial wealth to gain social status.

Consumer revolution:

Exotic colonial goods became increasingly available and affordable:

• Sugar: transformed from luxury to everyday commodity, consumption increased sixfold between 1660–1730
• Tobacco: smoking became widespread across social classes
• Coffee and tea: coffee houses proliferated in London and other cities, becoming centres of business and political discussion
• Cotton textiles: Indian calicoes and chintz became fashionable, prompting protective legislation for British wool and silk industries

Cultural impact:

Colonial wealth funded country houses, art collections and patronage. Merchants commissioned portraits showcasing their prosperity. Architecture incorporated symbols of global trade—decorative motifs featuring exotic plants, animals and enslaved people appeared in grand houses.

However, this wealth was directly built on the exploitation and enslavement of Africans and the dispossession of indigenous peoples—a reality often obscured in contemporary British culture.

Political and financial developments

Imperial expansion influenced British political institutions and financial innovation during this period.

Political power of merchant interests:

Trading companies and colonial merchants lobbied Parliament to protect their interests. The East India Company wielded enormous political influence, effectively governing territories in India. Wealthy merchants entered Parliament, using political power to secure favourable legislation.

Financial innovation:

The expensive nature of overseas trade drove financial developments:

• Joint-stock companies allowed investors to pool capital for ventures too expensive for individuals
• Marine insurance developed to protect against ship losses
• Bills of exchange facilitated long-distance transactions
• The Bank of England (founded 1694) stabilised public finances, partly through revenue from colonial customs

Government revenue:

Customs duties on colonial imports became a major revenue source. By 1730, approximately one-third of government income derived from customs, funding the Royal Navy which protected trade routes and colonies.

Wars and imperial competition:

Britain fought wars partly to secure commercial advantages:

• War of the Spanish Succession (1701–1714) resulted in the Treaty of Utrecht (1713), which gave Britain the Asiento—the contract to supply enslaved Africans to Spanish colonies
• Naval supremacy became a priority, with the Royal Navy protecting merchant shipping and challenging French and Spanish colonial power

Regional impact across Britain

Imperial trade affected different British regions distinctly.

Port cities:

• Bristol: dominated the transatlantic slave trade until Liverpool's rise; merchants invested slave trade profits in land and civic buildings
• Liverpool: emerged as a major slaving port after 1700, with approximately 40% of European slave trade by 1730
• Glasgow: developed tobacco trade with Virginia and Maryland, becoming Scotland's premier commercial city
• London: remained the dominant port, controlling East India trade and serving as the financial centre

Manufacturing regions:

Areas producing goods for export benefited from colonial markets:

• Lancashire and Yorkshire textiles supplied enslaved people on plantations
• Birmingham and Sheffield metalware (guns, tools, chains) traded in Africa and colonies
• Pottery and glassware industries developed partly for colonial markets

Agricultural areas:

Sugar refining created demand for agricultural produce to feed urban workers. However, some regions saw limited benefit from empire, particularly remote rural areas distant from trade networks.

Resistance and opposition

While rarely highlighted in contemporary British sources, resistance to slavery and imperial exploitation existed.

Enslaved people's resistance:

• Rebellions on slave ships during the Middle Passage
• Plantation revolts in the Caribbean, though brutally suppressed
• Maroon communities of escaped enslaved people in Jamaica

Early opposition in Britain:

Opposition to slavery remained limited during this period, though Quakers began questioning its morality in the early 18th century. However, the economic benefits meant most Britons accepted or ignored the brutality underpinning imperial wealth.

Worked examples

Example 1: Explain one way the transatlantic slave trade affected Britain's economy (4 marks)

Sample answer:

One way the transatlantic slave trade affected Britain's economy was through the growth of port cities involved in the trade. Liverpool and Bristol expanded rapidly as merchants invested profits from slave voyages in warehouses, docks and shipbuilding facilities. This created employment for dock workers, sailors, shipbuilders and merchants. The wealth generated also funded other industries, as slave trade profits were invested in manufacturing businesses and land, multiplying the economic impact across Britain.

Mark scheme guidance:

• 1 mark: simple statement (e.g., "it made merchants rich")
• 2 marks: developed statement showing impact (e.g., "port cities expanded")
• 3-4 marks: explained impact with specific detail showing how the change affected the economy

Example 2: "The main reason Britain's overseas trade grew between 1688 and 1730 was government policy." How far do you agree? (16 marks + 4 SPaG)

Sample answer structure:

Introduction: State your argument—government policy was important, but plantation economies and consumer demand were equally significant.

Paragraph 1 (Agreement): Government policies like the Navigation Acts protected British merchants from foreign competition, ensuring colonial goods passed through British ports. The Treaty of Utrecht (1713) gave Britain the Asiento, increasing involvement in the slave trade. These policies created a framework for commercial expansion.

Paragraph 2 (Agreement): Government support for joint-stock companies like the Royal African Company provided structures for expensive overseas ventures. Military protection from the Royal Navy secured trade routes.

Paragraph 3 (Counter-argument): However, plantation economies in the Caribbean drove trade growth independently of policy. The profitability of sugar plantations created massive demand for enslaved labour and manufactured goods, which would have encouraged trade regardless of government intervention.

Paragraph 4 (Counter-argument): Consumer demand in Britain transformed colonial goods from luxuries to necessities. Rising sugar and tobacco consumption created markets that merchants eagerly supplied. This demand-driven growth occurred beyond government control.

Conclusion: Government policy provided the legal framework and protection, but economic factors—plantation profitability and consumer demand—were equally important. All three factors worked together to expand trade.

Mark scheme guidance:

• Level 4 (13-16 marks): sustained analysis of both sides, reaching a substantiated judgement
• Level 3 (9-12 marks): explained analysis of both sides but limited evaluation
• Level 2 (5-8 marks): description or simple explanation
• Level 1 (1-4 marks): generalised statements

Example 3: Describe two features of the Triangular Trade (4 marks)

Sample answer:

One feature of the Triangular Trade was the transportation of manufactured goods from Britain to West Africa, including textiles, guns and metal goods, which were exchanged for enslaved people. Another feature was the Middle Passage, where enslaved Africans were transported across the Atlantic to Caribbean and American colonies in horrific conditions, with many dying during the voyage.

Mark scheme guidance:

• 2 marks per feature: 1 mark for identifying, 1 mark for supporting detail

Common mistakes and how to avoid them

• Confusing causation and consequence: Don't simply describe what happened; explain why changes occurred and what effects they had. For example, don't just state "sugar imports increased"—explain this was because plantation production expanded using enslaved labour, creating cheaper sugar that became affordable for ordinary consumers.

• Treating this period as identical to later empire: The British Empire in 1688–1730 was primarily focused on Atlantic trade and Caribbean plantations, not the territorial empire in India and Africa that developed later. Avoid anachronistic references to Victorian imperial attitudes.

• Ignoring the human cost: Examiners expect acknowledgement that imperial wealth was built on slavery and exploitation. Balanced answers address both economic benefits to Britain and the brutal system that generated them.

• Vague statements about "trade": Specify which goods, which regions, and which groups benefited. "Trade increased" is too general; "sugar imports from Jamaica tripled, enriching Bristol merchants but depending on enslaved labour" is specific and analytical.

• Neglecting regional variation: Britain wasn't uniformly affected—port cities and manufacturing regions benefited far more than agricultural areas. Show awareness of geographical differences.

• Weak chronology: The period begins with the Glorious Revolution (1688) and includes the Treaty of Utrecht (1713). Use these chronological markers to structure answers and show change over time.

Exam technique for "British Period Study: The Impact of Empire on Britain, c.1688–c.1730"

• Command word awareness: "Explain" requires causation or consequence, not just description. "How far do you agree" demands evaluation of different factors with a substantiated judgement. "Describe" needs accurate factual detail with supporting information.

• Use the mark allocation: A 4-mark question needs two developed points or one explained point with specific detail. A 16-mark essay requires multiple paragraphs addressing different perspectives, not just one line of argument.

• Integrate specific evidence: Replace general statements with precise examples—name specific ports (Bristol, Liverpool), specific goods (sugar, tobacco), specific policies (Navigation Acts, Treaty of Utrecht), and specific figures where possible (400,000 enslaved people transported 1690–1730).

• Link to the question throughout: Every paragraph should explicitly connect back to the question's focus. If asked about economic impact, continuously emphasise economic consequences rather than drifting into political or social issues unless directly relevant.

Quick revision summary

Between 1688–1730, British imperial expansion, particularly in the Caribbean and North America, transformed Britain economically and socially. The transatlantic slave trade and Triangular Trade system generated enormous wealth through plantation agriculture, especially sugar production. Port cities like Bristol and Liverpool expanded rapidly, while the re-export trade made Britain Europe's commercial hub. Colonial goods became everyday consumer items, and merchant wealth challenged traditional social hierarchies. Government policies like the Navigation Acts protected British commercial interests. However, this prosperity was built on the brutal exploitation of enslaved Africans and the violence of colonial conquest—a human cost that underpinned Britain's growing imperial power.
