Weighing Historical Causes

Analyse events with many causes and effects: sort causes into types (long-term and short-term, underlying and trigger), evaluate which mattered most, and defend that judgement with evidence

What a learner can do afterwards

  • Sort the causes of an event into long-term and short-term (e.g., tensions building for years versus the spark that set things off)
  • Argue which cause of an event was the most important and back the claim with evidence
  • Explain how one event's consequences became causes of the next (e.g., a harsh peace settlement feeding a later conflict)

The lesson

Big events in history almost never have a single cause. When you study something like a war or a revolution, you find several causes tangled together. Some built up slowly over years. One of them was usually the spark that set the event off right then.

The first two boxes took years to build. The third box is the trigger, the spark that happened right before the war started.

Historians sort causes into two types. Long-term, or underlying, causes are the conditions that made the event likely: rivalries, unfair laws, years of tension. The trigger is the specific spark that happened right before the event and set it off.

Try it together

After World War One ended, the losing countries were forced to sign a harsh peace treaty. That treaty left people angry and struggling for years. That anger became one of the causes of World War Two two decades later. A consequence of one event can become a cause of the next.

Good to know

When you argue which cause mattered most, don't just pick the one you find most interesting. Ask yourself: could the event still have happened without this cause? Then back your answer with evidence, not just an opinion.

Sort causes into long-term and trigger, then argue which mattered most using evidence, not opinion.
