Long-term, short-term and trigger causes

GCSE
Distinguish long-term, short-term and trigger causes
Video lesson: Long-term, short-term and trigger causesComing soon
Context. In 1666 a fire began in a bakery on Pudding Lane in London. It spread across the city for several days. Why did such a small fire become so big? Historians sort the causes into three kinds.

A long-term cause builds up over many years. It creates the conditions for the event. A short-term cause is something that happens shortly before the event, and makes it more likely. A trigger is the event that sets the main event off.

For the Great Fire of London (1666): the houses were mostly built of timber and thatch and packed closely together (long-term); the summer had been hot and dry and a strong wind blew (short-term); a fire in a bakery started the blaze (trigger).

The Peasants’ Revolt (1381). The Black Death (1348 to 1349) killed many workers, so labour became scarce (long-term). The government passed the Statute of Labourers in 1351 to fix wages (long-term). Poll taxes were collected in the late 1370s and in 1380 (short-term). The collection of the tax in 1381 led to protests that turned into a revolt (trigger). check fact: confirm the tax dates and the place of the first protests in your textbook.

Key ideas

  • Long-term: builds up over years; creates the conditions.
  • Short-term: happens shortly before and makes the event more likely.
  • Trigger: the event that sets the main event off.
  • The same factor can be long-term in one event and short-term in another.
Worked example 3.1.1
Classify the fire in the bakery on Pudding Lane: long-term, short-term or trigger? Write the word.

Method. Ask what the fire did.

  1. Look at its role. The bakery fire was the event that started the blaze.
    started the blaze
  2. Name the type. The event that sets the main event off is a trigger.
    trigger
  3. Write the answer.
    trigger

Check. It did not build up over years; it started the spread in one day.

Worked example 3.1.2
Name a long-term cause of the Peasants’ Revolt linked to the Black Death. Write the words.

Method. Find the effect of the Black Death on workers.

  1. Find the effect. The Black Death killed many workers, so labour became scarce.
    labour became scarce
  2. Name the cause. A labour shortage that lasted for years is a long-term cause.
    labour shortage
  3. Write the answer.
    labour shortage

Check. The shortage built up over years after 1348.

Worked example 3.1.3
Name a short-term cause of the Great Fire of London. Write the words.

Method. Look for a condition that happened shortly before the fire.

  1. Find the condition. The summer had been hot and dry, with a strong wind.
    hot, dry, windy
  2. Name the cause. Weather just before and during the fire is short-term.
    hot, dry weather
  3. Write the answer.
    hot, dry weather

Check. Any one weather condition is accepted, such as strong wind.

Watch out

Watch out: a trigger is not the most important cause just because it is last. The trigger set off the event; the long-term causes made it likely.

Exam tip

Exam tip. Name the type of cause in your first words: “A long-term cause was…”. Then give one piece of evidence.

(c)(c) the collection of the tax in 1381 that sparked protests
9
RExplain the difference between a long-term cause and a trigger in one sentence. Accept any sentence that says a long-term cause builds up over time, while a trigger is the event that sets the main event off.
10
PSFor the invented riot at Hollin Bridge in 1858: workers had resented long hours for years. In 1858 the owners cut wages. A stone was thrown at a manager’s window and a riot followed. Name the trigger in three words or fewer. Accept any answer that names the stone thrown at the window.
11
PSFor the same invented riot, name the short-term cause: the event in 1858 that came just before the riot. Write the words.
12
RGive one reason why a historian should separate long-term, short-term and trigger causes. Accept any reason that says it shows how causes built up over time, and which one set the event off.
3.2

Necessary and sufficient causes; cause and consequence

GCSE
Explain necessary and sufficient causes, and tell a cause from a consequence
Video lesson: Necessary and sufficient causes; cause and consequenceComing soon
Context. A cause comes before an event and helps to bring it about. A consequence comes after it. Some causes are essential; others are enough on their own. Historians use these words precisely.

A necessary cause is one without which the event would not have happened. A sufficient cause is enough, on its own, to bring the event about. A consequence is an effect of an event, and it comes after the event. The rebuilding of London in brick after 1666 was a consequence of the Great Fire; the bakery fire was a cause of it.

Key ideas

  • Necessary: without it, the event would not have happened.
  • Sufficient: enough on its own to bring the event about.
  • Consequence: an effect that comes after the event.
  • A cause is never a consequence of the same event.
Worked example 3.2.1
Is the rebuilding of London in brick after 1666 a cause or a consequence of the Great Fire? Write the word.

Method. Check the order of events.

  1. Check the order. The rebuilding came after the fire, so it is an effect of the fire.
    after the fire
  2. Name the type. An effect that comes after the event is a consequence.
    consequence
  3. Write the answer.
    consequence

Check. The rebuilding was partly ordered by a government rule, which is also a consequence.

Worked example 3.2.2
Is the labour shortage after the Black Death a cause or a consequence of the Black Death? Write the word.

Method. Check the order.

  1. Check the order. The shortage came after the disease killed many workers.
    after the disease
  2. Name the type. An effect that follows the disease is a consequence.
    consequence
  3. Write the answer.
    consequence

Check. The shortage was then a cause of the wage problem that led to the Statute of Labourers.

Worked example 3.2.3
Give one necessary condition for a fire to start. Accept any answer that says fuel, heat and oxygen (or a spark in dry materials).

Method. Think about what a fire needs.

  1. Recall. A fire needs fuel, heat and oxygen to burn.
    fuel, heat, oxygen
  2. Name it. Without any one of these, a fire would not start.
    necessary
  3. Write the answer.
    Accept any answer that says fuel, heat and oxygen (or a spark in dry materials).

Check. Each is necessary; together they are sufficient for a fire.

Watch out

Watch out: “sufficient” does not mean “the only cause”. A sufficient cause is enough by itself, but there may be more than one sufficient cause.

Exam tip

Exam tip. When asked whether something is a cause or a consequence, check the date first: a consequence must come after the event.

Exercise 3B  Necessary and sufficient causes; cause and consequence

1
FWrite the word for a cause without which an event would not have happened. The word starts with n.
2
FWrite the word for a cause that is enough, on its own, to bring the event about. The word starts with s.
3
FWrite the word for an effect that comes after an event. The word starts with c.
4
FWas the Statute of Labourers (1351) a cause or a consequence of the Black Death? Write the word.
5
FWas the labour shortage after the Black Death a cause or a consequence of the disease? Write the word.
6
FWas the rise in wages after 1349 a cause or a consequence of the labour shortage? Write the word.
7
FClassify each of these as a cause or a consequence of the Great Fire of London. Write cause or consequence for each.
(a)(a) a fire in a bakery on Pudding Lane
(b)(b) the rebuilding of London in brick
(c)(c) a hot, dry summer before the fire
8
PSGive one consequence of the Great Fire of London for the city’s buildings. Accept any answer that says London was rebuilt, with more brick and stone.
9
RUsing your own knowledge, give one condition that a fire needs. Accept any answer that says fuel, heat and oxygen.
10
RExplain the difference between a necessary cause and a sufficient cause in one sentence. Accept any sentence that says a necessary cause must be present, while a sufficient cause is enough on its own.
11
RIs a cause always a sufficient cause? Write yes or no.
3.3

Ranking causes by importance

GCSE
Rank causes by importance, using stated criteria and a reason
Video lesson: Ranking causes by importanceComing soon
Context. An exam question often asks “Which was the most important cause?” You must choose one, but you must also give a reason. The reason is a criterion: a standard you use to judge importance.

Useful criteria are: how direct the cause was (how close it was to the event); how necessary it was (whether the event would have happened without it); how long lasting it was (its duration); and how many people it affected. Use one or two criteria, and say which you have used.

A ranking without a reason is only an opinion. Always say why one cause matters more than another.

Key ideas

  • Choose a criterion and say what it is.
  • Criteria: direct, necessary, long-lasting, wide in effect.
  • Rank causes, then give the most important with a reason.
  • Both long-term and trigger causes can be the most important, depending on your criterion.
Worked example 3.3.1
Rank the labour shortage and the poll tax as causes of the Peasants’ Revolt. Which is more important under the “necessary” criterion? Write the words.

Method. Ask which would have been missing without the other.

  1. Rank. The labour shortage created the wage grievance, which the poll tax made worse.
    shortage first
  2. Name the criterion. Under the necessary criterion, the shortage is more important because the grievance existed before the tax.
    labour shortage
  3. Write the answer.
    the labour shortage

Check. Other historians rank the poll tax as more important because it was the trigger; give your reason.

Worked example 3.3.2
Which criterion asks how long a cause lasted? Write the word.

Method. Match the criterion to its question.

  1. Match. A criterion that asks how long something lasted is about its duration.
    duration
  2. Write. The word is duration.
    duration
  3. Write the answer.
    duration

Check. Duration is the length of time a cause affected the event.

Worked example 3.3.3
Give a judgement and a reason: which was the most important cause of the Great Fire, the dry weather or the wooden houses? Accept any answer that gives a reason with one criterion.

Method. Choose one criterion and apply it to both causes.

  1. Choose a criterion. Use how necessary each was for the fire to spread widely.
    necessary
  2. Apply it. Wooden houses packed closely together helped the fire spread, and this lasted for years.
    wooden houses and duration
  3. Write the answer.
    Accept any answer that gives a reason with one criterion.

Check. Another criterion could reach a different judgement; the reason matters.

Watch out

Watch out: “it was the most important because it was the biggest” is not a criterion. Name a criterion such as how direct, how necessary or how long lasting.

Exam tip

Exam tip. Write: “The most important cause was… because, using the criterion of…” Then add one piece of evidence.

Exercise 3C  Ranking causes by importance

1
PSRank two causes of the Peasants’ Revolt: (1) the poll taxes, (2) the labour shortage after the Black Death. Write the number of the more important cause under the criterion of how necessary it was.
2
RGive one reason for your ranking in the question above. Accept any answer that says the labour shortage created the wage grievance, which the poll taxes then made worse.
3
FWrite the word for the criterion that asks how long a cause lasted. The word is about time: write it in one word.
4
FWrite the word for the criterion that asks whether the event would have happened without the cause. The word starts with n.
5
RName one criterion for judging the importance of a cause. Accept any criterion, such as how direct, how necessary, how long lasting, or how many people it affected.
6
FA historian says the bakery fire was the most important cause of the Great Fire. Is this a judgement or a fact? Write one word.
7
RA historian ranks the hot, dry weather above the bakery fire, because a fire needs fuel and spreads with the weather. Is this ranking a judgement? Write yes or no.
8
PSFor the invented riot at Hollin Bridge, rank these: (a) the wage cut of 1858, (b) the stone thrown at a window. Which is more important under the criterion of how direct? Write the letter.
9
FWrite the first step in ranking causes. One word: identify, rank or argue.
10
RExplain in one sentence why a historian must give a reason when ranking causes. Accept any sentence that says a ranking without a reason is only an opinion.
11
RRank three causes of the Peasants’ Revolt and give the top one. Write the top cause. Accept any answer naming the labour shortage or the poll tax, with a reason.
12
RWrite one sentence that gives a judgement with a criterion for the most important cause of the Great Fire of London. Accept any sentence that names one cause and a criterion, such as how direct or how necessary.
3.4

Chains of causation

GCSE
Link causes into a chain in which one factor leads to another
Video lesson: Chains of causationComing soon
Context. A question may ask “How did one factor lead to another?” The answer is a chain: each cause leads to the next, and each link must be explained, not just listed.

The chain for the Peasants’ Revolt begins with the Black Death (1348 to 1349). The disease killed many workers. Fewer workers meant higher wages. The Statute of Labourers (1351) tried to fix wages. Anger grew, and the poll taxes made it worse. The protests of 1381 turned into a revolt.

A chain uses arrows, and each link uses a linking word such as so, because or which led to.

Chain for the Peasants’ Revolt: Black Death → labour shortage → higher wages → Statute of Labourers → anger → poll taxes → protests → revolt. Check fact: confirm the tax dates in your textbook.

Key ideas

  • A chain shows one factor leading to another, with arrows.
  • Each link needs an explanation: why did one lead to the next?
  • Linking words: so, because, which led to, as a result.
  • A chain can contain both long-term and trigger causes.
Worked example 3.4.1
In the chain for the Peasants’ Revolt, what came directly after the Black Death? Write the words.

Method. Read the chain from the left.

  1. Read the chain. The Black Death is followed by an arrow to the next link.
    arrow
  2. Name the link. The link after the Black Death is the labour shortage.
    labour shortage
  3. Write the answer.
    labour shortage

Check. The shortage is the first link in the chain.

Worked example 3.4.2
Explain the link between the labour shortage and the Statute of Labourers in one sentence. Accept any sentence that says the shortage raised wages, so the government passed the statute to fix them.

Method. Use a linking word.

  1. Explain the first part. The shortage meant workers could demand higher wages.
    higher wages
  2. Explain the link. So the government passed the statute to fix wages.
    so
  3. Write the answer.
    Accept any sentence that says the shortage raised wages, so the government passed the statute to fix them.

Check. The link must say why one led to the next.

Worked example 3.4.3
Write the chain for the Great Fire of London, using three links. Accept any chain such as: strong wind → fire spreads → houses burn, with the bakery fire at the start.

Method. Start with the trigger and follow the spread.

  1. Start. The bakery fire starts the blaze.
    bakery fire
  2. Spread. Strong wind and timber houses let the fire spread.
    wind and timber
  3. Write the answer.
    Accept any chain such as: strong wind → fire spreads → houses burn, with the bakery fire at the start.

Check. A chain can start with any link, but it must be ordered in time.

Watch out

Watch out: a list is not a chain. “Wind, wood and a bakery” lists causes. A chain says how each one led to the next.

Exam tip

Exam tip. In “how did one factor lead to another?” questions, write one sentence per link, each with a linking word.
