Learning goals
Learners will
- Distinguish between long-term, short-term and immediate causes.
- Apply criteria to judge historical significance.
- Identify change and continuity over time.
Success looks like
- I can classify causes of an event as long-term, short-term or a trigger.
- I can use criteria to explain why an event or person is significant.
- I can identify what changed and what stayed the same across a period.
The big idea
Historical events rarely have a single cause. Historians separate long-term causes (deep conditions), short-term causes (developments in the months or years before) and triggers (the immediate spark).
For example, for the outbreak of World War I: long-term causes include rival alliances, militarism, imperial competition and nationalism; short-term causes include Balkan crises; the trigger was the assassination of Archduke Franz Ferdinand in Sarajevo on 28 June 1914.
Causes also interact. Historians debate which factors mattered most, and consider contingency: how chance and individual choices shaped outcomes.
Significance is a judgement. Common criteria include: How many people were affected? How deeply? For how long? Did it reveal something important about the period? Is it remembered, and by whom? Significance can differ for different groups.
Change and continuity are studied together. Even revolutionary periods contain continuities, and change may be uneven across groups, places and aspects of life.
Worked examples
Classifying causes
Classify these causes of World War I: alliance system; assassination of Franz Ferdinand; Balkan Wars of 1912–13.
- Alliance system developed over decades: long-term.
- Balkan Wars occurred shortly before: short-term.
- Assassination on 28 June 1914: trigger.
Answer: Long-term: alliances. Short-term: Balkan Wars. Trigger: assassination.
Judging significance
Use criteria to explain the significance of the 1992 Mabo decision.
- Impact: changed Australian law on land ownership.
- Durability: led to the Native Title Act 1993 and ongoing native title determinations.
- Revelation: exposed the legal fiction of terra nullius.
- Remembrance: commemorated on Mabo Day (3 June) and at the end of National Reconciliation Week.
Answer: Highly significant by criteria of impact, durability, revelation and remembrance.

What does contingency mean in history?
Outcomes depended partly on chance and choices — Contingency stresses that things could have turned out differently.

How many people were affected and for how long — Scale and duration of impact are key criteria.
Studying change and continuity together helps historians to…
see that even major change often includes things that stayed the same — Change and continuity are two sides of analysing a period.
In what city was Archduke Franz Ferdinand assassinated?

Watch out for
- Students sometimes list causes without ranking or linking them. Strong analysis explains relationships between causes.
- Significance is not the same as fame; a little-known event can be highly significant for a particular community.
Tips for parents
- Ask 'Why did this happen?' and 'Why does it matter?' about news events to practise causation and significance.
- Where topics involve First Nations histories, discuss how significance may be understood differently by different communities, and seek community perspectives.
- Check which historical concepts your state or territory course emphasises.
Go further
- Create a cause diagram for an event you are studying, using arrows to show links between causes.
- Rank five events of the twentieth century by significance and justify your ranking.
- Write a counterfactual paragraph: what might have happened if one cause had been absent?
