Can I choose any topic for my IB History IA?

You have considerable freedom, but the topic must support a focused historical investigation and comply with the guide used by your cohort. Your teacher must approve the question and may restrict subjects because of school deadlines, source access, or overlap with other work. A political, social, economic, cultural, military, or local history topic can all be suitable. What matters is your ability to analyze evidence, evaluate perspectives, and reach a reasoned conclusion. Confirm any date-related eligibility rule directly with your teacher because requirements can change between course versions.

Does an IB History IA need both primary and secondary sources?

A strong investigation normally benefits from both, although simply including each type does not guarantee quality. Primary sources provide evidence created by participants, institutions, or observers, while secondary works help establish context and historical interpretations. Your sources should perform different functions rather than repeat the same account. For example, government memoranda can be compared with oral testimony and historians' later explanations. Source selection should always be driven by the research question rather than by an arbitrary target number.

How narrow should an IB History IA research question be?

The question should normally isolate one outcome, place, period, and central factor or comparison. A timeframe of several years is often manageable, although a single crisis may require only days or months. If your plan requires extensive background on multiple countries, leaders, and decades, it is probably too broad. Try explaining your proposed argument in three analytical paragraphs before approving the question. If each paragraph can make a distinct judgement supported by evidence, the scope is likely workable.

Are popular topics such as Hitler or the Cold War a bad choice?

Popular subjects are not automatically weak, and examiners do not award marks for obscurity. The problem arises when students choose a familiar subject without finding a specific question or distinctive body of evidence. A narrow investigation into one policy, decision, audience, or diplomatic episode can work very well. Popular areas may actually provide better access to digitized archives and established historiographical debates. Your analysis and source use matter more than whether another student has studied the same general period.

How many sources should I find before committing to a History IA topic?

There is no universal number that proves a topic is viable, since sources vary greatly in depth and relevance. Before committing, identify two central sources suitable for close evaluation, several additional pieces of primary evidence, and at least three substantial secondary works. Check that these sources offer more than one perspective and can be accessed in full. A search-result snippet, book review, or unattributed summary is not an adequate substitute for the original publication. It is better to use a controlled range of relevant sources critically than to assemble a long bibliography that barely enters the argument.

Can I use oral history interviews in my IB History IA?

Yes, oral histories can provide valuable evidence about experience, memory, identity, and perspectives that official records overlook. They must still be evaluated in relation to when the interview occurred, who conducted it, how questions were framed, and how memory may have changed. Retrospective testimony should not automatically be treated as a precise record of every event. Compare it with contemporary documents, other interviews, and secondary scholarship wherever possible. If you conduct an interview yourself, discuss consent, recording, storage, and citation procedures with your teacher before collecting evidence.

IB History IA Topics That Actually Work

Choosing an IB History IA topic is not about finding the most original event. It is about identifying a focused historical problem that you can investigate through accessible evidence, competing interpretations, and a defensible judgement.

The strongest topics examine one factor, policy, decision, group, or turning point within a defined period. This guide provides workable examples, reliable source routes, and a practical method for testing your question before committing to it.

What makes an IB History IA topic workable?

A promising subject is not automatically a workable investigation. “The Cold War” is a subject, while “How significant was Kennedy's naval quarantine in resolving the Cuban Missile Crisis?” is an investigation.

Apply five tests before committing:

Focused: Can you answer it without narrating decades of background?
Arguable: Could informed historians reach different conclusions?
Evidence-based: Can you access relevant primary and secondary sources?
Analytical: Does it require judgement about causation, significance, consequence, or perspective?
Practical: Can you understand, retain, and cite the essential evidence?

The RevisionDojo guide to choosing a focused History IA question explains how to refine an initial idea. Your teacher must still approve the final question.

Check which IB History course applies to you

IB History is undergoing a syllabus transition. Students completing final assessment in 2027 follow the existing course, where the historical investigation is marked out of 25. The current IB History subject brief states that it contributes 25% at SL and 20% at HL.

The redesigned course has first assessment in 2028. Its investigation is marked out of 24, with assessment focused on the inquiry question, analysis of sources, and synthesis of evidence, according to the official 2028 subject brief. Ask your teacher which guide applies because older online advice may not match your criteria.

Source-rich IB History IA topics

These are starting points rather than titles to copy. Adjust the factor, place, or dates after preliminary reading.

Area	Possible research question	Realistic source route
Cuban Missile Crisis	To what extent was Kennedy's naval quarantine responsible for the peaceful resolution of the crisis in October 1962?	Wilson Center diplomatic records, US government memoranda, and scholarship by Aleksandr Fursenko, Timothy Naftali, or Michael Dobbs.
Japanese American incarceration	To what extent did racial prejudice, rather than military necessity, shape the implementation of Executive Order 9066 in 1942?	Densho oral histories and documents, US National Archives records, and works by Roger Daniels or Greg Robinson.
Montgomery Bus Boycott	How significant was economic pressure compared with legal action in ending Montgomery bus segregation in 1955-1956?	Rosa Parks papers, boycott material, court decisions, newspapers, and Montgomery Improvement Association records.
British women's suffrage	To what extent did WSPU militancy weaken support for women's suffrage in Britain between 1909-1914?	Suffrage newspapers, correspondence, parliamentary debates, police records, and scholarship by June Purvis or Martin Pugh.
Chile under Allende	How significant was US covert intervention in destabilizing Salvador Allende's government between 1970-1973?	CIA cables, embassy records, Chilean evidence, and scholarship by Peter Kornbluh or Tanya Harmer.
Partition of India	To what extent did the breakdown of provincial authority contribute to violence in Punjab during 1947?	Partition oral histories, government papers, newspapers, and works by Ian Talbot, Urvashi Butalia, or Yasmin Khan.
Soweto uprising	How significant was the Afrikaans-medium policy in causing the Soweto uprising of June 1976?	Testimony, education policy, student accounts, photographs, and contemporary reporting.
Nuremberg Trials	To what extent did captured German documents strengthen the prosecution's case in 1945-1946?	Trial transcripts, submitted evidence, judgements, museum collections, and legal histories.
New Deal photography	To what extent did FSA photography shape American perceptions of rural poverty between 1935-1940?	Photographs, captions, newspapers, posters, and evidence about publication context and government purpose.

These topics have substantial online collections covering the Cuban Missile Crisis, Japanese American incarceration, Montgomery boycott, women's suffrage, Chile, Partition, Soweto, Nuremberg, and the New Deal. An archive's existence does not guarantee that every document will be accessible or relevant, so inspect individual items before approval.

How to turn a broad idea into a strong question

A useful structure is:

To what extent was [specific factor] responsible for [defined outcome] in [place] during [dates]?

“How did propaganda affect Nazi Germany?” is too broad. “To what extent did Nazi radio propaganda contribute to support for the regime among German workers between 1933-1936?” defines the medium, population, outcome, and period.

Another structure is comparative significance:

How significant was [factor A] compared with [factor B] in producing [outcome]?

This encourages evaluation rather than a list of causes. Keep the comparison controlled, since comparing entire countries or movements usually produces excessive description.

Verify the sources before approving the topic

Do not finalize a question because an archive homepage appears in your search results. Open individual documents and check what you can read, download, and cite.

Use this preliminary source test:

Find two central sources suitable for close evaluation.
Locate additional primary evidence representing different positions or source types.
Find at least three serious secondary works by identifiable historians.
Confirm that a genuine interpretive disagreement exists.
Record publication details and page numbers immediately.

Primary sources are not automatically more accurate than secondary sources. A government report may conceal failures, an oral history can reflect later memory, and a photograph may involve staging or editorial selection. Explain such limitations precisely rather than dismissing a source as merely “biased.” The Library of Congress provides guidance on finding and filtering digitized primary sources.

Topic choices that usually cause problems

Several types of question make sustained historical analysis difficult:

Long periods: “Why did the Roman Empire fall?” is too large for a short investigation.
Counterfactuals: “Would Germany have won without D-Day?” depends heavily on speculation.
Purely moral questions: “Was dropping the atomic bomb wrong?” should become a question about motives, necessity, or consequences.
Biographical summaries: “How did Mandela change South Africa?” invites narration unless narrowed to one decision.
Single-source topics: One speech, diary, or poster rarely supports an entire investigation.
Loaded questions: “How did Churchill's brilliant leadership save Britain?” assumes its conclusion.

Local history can work well when newspapers, council minutes, photographs, election material, or oral histories are available. Confirm access and ethical requirements before choosing it.

A practical selection process

Shortlist three questions and prepare a one-page feasibility sheet for each. Include the tentative question, two primary sources, three secondary works, the central historical disagreement, and two possible arguments.

Discuss the sheets with your teacher before drafting. The RevisionDojo step-by-step History IA guide can help organize the investigation, while the History IA criteria guide connects evidence and evaluation to assessment. Use History IA exemplars to examine structure and analytical choices, not to copy topics or wording.

Conclusion

Effective IB History IA topics are narrow, arguable, historically significant, and supported by evidence you can genuinely access. A modest question with strong sources is usually better than an ambitious question built on summaries or inaccessible archives.

Confirm your assessment criteria, test possible questions against real documents, and obtain teacher approval. RevisionDojo's History IA guide, exemplars, IA Feedback, and Jojo AI can then help you check focus and identify weaknesses while keeping the final argument and writing your own.
