Historical Conspiracy Theories Worksheet

Read the case file and analyse the evidence. A conspiracy theory alleges that a secret group is acting together, often with claims that are difficult to verify. Distinguish documented events from speculation, and support conclusions with evidence.

Case file: The sinking of the Rainbow Warrior

On 10 July 1985, explosions sank the Greenpeace ship Rainbow Warrior in Auckland Harbour. Greenpeace planned to sail the vessel to protest French nuclear testing in the Pacific. Fernando Pereira, a photographer aboard the ship, died. New Zealand police investigated and arrested two French agents, who pleaded guilty to manslaughter and wilful damage. The agents were sentenced to prison. France initially denied involvement. Later, French officials acknowledged that French intelligence agents had carried out the operation. The case caused a major diplomatic dispute between New Zealand and France. The facts of the bombing and state involvement are documented; questions about who authorised specific decisions, what others knew, or whether further people were involved require separate evidence. A claim that goes beyond available evidence is not established simply because some parts of the event were secret.

Evidence desk

Classify what each item can establish. An official finding or admission is strong evidence for the specific point it confirms, but it does not automatically prove every related claim.

A. Police arrested two French agents; both pleaded guilty to offences connected with the bombing.

B. France initially denied involvement, then later acknowledged that French intelligence agents carried out the operation.

C. Someone says, without naming a source or providing records, that a much larger secret group planned the bombing.

D. No evidence is provided about whether senior officials beyond those already identified knew about a particular decision.

Analyse and evaluate

Answer using details from the case file. Where a claim is not supported, explain what evidence would be needed.

1.Which statement best separates documented history from an unproven extension of the story?

The bombing never happened because governments sometimes lie.
French agents carried out the bombing; any claim about additional planners needs its own evidence.
Every official statement about the case must be true.
The case proves that all secret operations have the same organisers.

2.Identify two details in the case file that are documented, and state what each detail helps establish.

3.True or false: Because France initially denied involvement, every later claim about the bombing—including claims with no supporting evidence—should be treated as true. Explain your choice.

4.Complete the reasoning: The fact that a real, secret operation occurred prove that every proposed hidden motive or additional participant is .

5.A researcher wants to investigate whether officials beyond the two agents knew about the plan. Name two kinds of sources that could help answer this question, and explain one limitation of either source.

6.Match each source or statement to what it can most reasonably support.

A. A guilty plea by an arrested agent
B. An unsupported rumour about unnamed planners
C. A later official acknowledgement

2. A lead to investigate, not proof
1. Evidence of the specific offences admitted
3. Evidence that agents from the state carried out the operation

7.Why might people find a broader conspiracy claim persuasive after a government has concealed a real operation? Give one reason, then explain why that reason is not enough to establish the claim.

8.Assess the claim: “Since French agents carried out the bombing, a larger international organisation must also have planned it.” State whether the evidence in this case file supports the conclusion and explain the reasoning.

9.The bombing caused a diplomatic dispute between New Zealand and France. Explain one way this consequence mattered beyond the immediate investigation.

10.Write a two-sentence historical judgement about the Rainbow Warrior case. Sentence one must state a supported conclusion; sentence two must identify a limit or unanswered question.
