Topic Summary: The Great Plague of 1665
Key Terms
- Bills of Mortality: Weekly printed death counts by parish — under-reported because families concealed cases to avoid being shut up
- Miasma theory: Wrong belief that plague was caused by bad air — led to bonfires, posies, fumigation; none of it worked
- Shutting up houses: Sealing infected households for 40 days — probably made transmission worse by trapping healthy with sick
- Pest houses: Isolation hospitals outside city walls — sensible idea, very limited capacity
- Buboes: Swollen, blackened lymph nodes — visible sign of infection that triggered house quarantine
Key Dates
- Spring 1665: Plague arrives in London, beginning in outer parishes (St Giles)
- Summer 1665: Rapid spread; rich (including Charles II) flee to countryside
- September 1665: Peak — 7,165 deaths in one week (week ending 7 September)
- Winter 1665-66: Cold kills flea population; plague begins to decline
- September 1666: Great Fire destroys much of the overcrowded wooden housing
Key People
- Samuel Pepys: Clerk of the Acts (Navy Board); stayed in London throughout; diary is the key primary source
- Charles II: Fled to Oxford with court — contrasts with his presence during the Great Fire 1666
- Daniel Defoe: Wrote A Journal of the Plague Year (1722) — fiction, NOT a genuine eyewitness account
Must-Know Facts
- ~100,000 deaths in London — approximately 25% of the population
- Peak: 7,165 deaths in one week, September 1665
- FARMS: Fleas on rats, Awful conditions, Rich fled, Miasma theory, Shutting up houses
- 40,000 dogs killed — actually worsened plague by removing rat predators
- Charles fled to Oxford — contrasts with his personal response to Great Fire 1666
- Miasma theory (bad air) was wrong — real cause was bacteria carried by rat fleas
- Bills of Mortality under-reported because families hid cases to avoid being shut up
- Pepys is the key primary source; Defoe wrote fiction 57 years later
Cross-Topic Links
- → Great Fire (Topic 54): The Plague (1665) and Great Fire (1666) were consecutive crises — Newton developed his laws of gravity at Woolsthorpe during the Plague year, and the Fire destroyed the overcrowded housing that had worsened plague spread.
- → Royal Society (Topic 55): The Plague exposed the failure of miasma theory and traditional medicine, demonstrating why the Royal Society's experimental approach mattered — Newton famously worked on gravity during the 1665-66 plague years.
- → Dutch Wars (Topic 52): The 1665-66 plague and fire drained England's finances at the same time as the Second Dutch War, explaining why Parliament refused to fund the navy adequately and why the Medway disaster happened.
- → Unit 4: Great Plague (Medicine Topic 38): This is the same event viewed from the Medicine Through Time thematic lens — Unit 4 analyses it in terms of continuity and change in public health responses across centuries.
- → Charles's Court (Topic 50): Charles fled to Oxford during the Plague but personally fought the Great Fire — this contrast in royal leadership is a key exam comparison point about how monarchy responded to national crises.
