How do you explain why something happened and rank the causes?
Explaining causation: giving developed, linked reasons why an event happened and ranking them (AO2).
A focused CCEA GCSE History guide to causation questions. Covers what a why question is really asking, how to give developed rather than listed reasons, how long-term and short-term causes link together, and how to rank causes to reach a judgement for top marks.

What this dot point is asking
The causation question asks you to explain why an event happened. It tests AO2, the use of the second-order concept of cause, supported by AO1 knowledge. The skill being marked is giving developed, linked reasons rather than a list, and ranking them to reach a judgement. Examiners reward answers that explain how causes connect and which mattered most, so you must move beyond naming reasons to analysing them.
Developed reasons, not a list
A weak answer lists three or four causes in a sentence each and stops. A strong answer takes each cause and explains the chain from cause to effect, anchored to a precise fact. The mark scheme rewards explanation, so every paragraph should answer the hidden question "and how did that lead to the event?".
Long-term and short-term causes
Events have causes that build up over time and causes that act as the final spark.
- Long-term causes are underlying conditions, such as discrimination in housing and voting that fed nationalist grievance in Northern Ireland over many years.
- Short-term causes are immediate triggers, such as a particular march, decision or crisis.
Strong answers link the two: the trigger only mattered because the long-term tensions were already there. Showing this connection, rather than treating causes as separate boxes, is what lifts an answer into the higher bands.
Ranking to reach a judgement
The top band asks you to decide which cause mattered most. Do not weigh causes equally and trail off. Argue a line: name the most important cause, explain why it outweighs the others, and acknowledge that it worked alongside them. A judgement such as "the deteriorating security situation triggered internment, but political pressure on Faulkner explains why so drastic a measure was chosen" shows ranking and earns the top marks.
Examples in context
Model causation paragraph. "The most important cause of internment was the collapse of security by 1971. IRA bombings and shootings had risen sharply, and the Stormont government wanted emergency powers to detain suspects without trial and remove them from the streets. This mattered more than political pressure because, without the surge in violence, there would have been no case for so extreme a step; yet the pressure on Brian Faulkner to be seen to act explains why internment, rather than a lesser measure, was chosen." This scores highly because it states a ranked judgement, develops the reason with precise evidence, and links it to a second cause.
Try this
Q1. What makes a reason "developed"? [2 marks]
- Cue. It names a cause, explains how it led to the event, and supports it with a specific fact.
Q2. What is the difference between a long-term and a short-term cause? [2 marks]
- Cue. A long-term cause is an underlying condition built up over time; a short-term cause is an immediate trigger or spark.
Q3. Why must a top-band answer rank the causes? [2 marks]
- Cue. Because the highest marks require a judgement on which cause mattered most, not an equal list of reasons.

Practice questions written in the style of CCEA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
CCEA Unit 1 (style)9 marksExplain why internment was introduced in Northern Ireland in 1971.Show worked answer →
A causation question testing AO1 and AO2. Give three or four developed, linked reasons and rank them.
Rising violence: by 1971 the security situation had deteriorated sharply, with IRA bombings and shootings, and the government wanted to remove suspects quickly.
Political pressure: the Stormont government under Brian Faulkner faced demands to be seen to act.
Intelligence failure: internment relied on out-of-date lists, swept up the wrong people and alienated the nationalist community.
Rank the causes: argue that the deteriorating security situation was the trigger, but that political pressure on Faulkner explains the decision to use such a drastic measure. A ranked judgement, not a list, reaches the top band.
CCEA Unit 2 (style)8 marksExplain why the Berlin Blockade happened in 1948.Show worked answer →
A causation question on the outline study. Give developed reasons and link them.
Currency reform: the Western Allies introduced a new currency, the Deutschmark, in their zones in 1948, which Stalin saw as a threat.
Ideological divide: the West wanted a strong, rebuilt Germany; the USSR feared a revived Germany and wanted to keep it weak.
Berlin's position: West Berlin lay deep inside the Soviet zone, giving Stalin the chance to squeeze it.
Rank: argue that the currency reform was the trigger, but the deeper cause was the breakdown of trust between East and West over Germany's future. A linked, ranked answer wins.
