1. Why use this guide?
Use this guide if you are looking for records of war crimes and criminals (both alleged and proved) from 1939-1945. It will tell you the types of records we hold and how to search for them.
2. What types of records does The National Archives hold?
- selected lists of war criminals and individual case files
- documentation relating to administration and policy
The records we hold mainly relate to:
- investigations and trials in Europe and the Far East
- the United Nations War Crimes Commission (UNWCC), whose role was to record and investigate war crimes and to advise governments on legal procedures for bringing suspects to trial
- the Central Registry of War Criminals and Security Suspects (CROWCASS), which assisted the UNWCC and allied governments in tracing ex-enemy nationals suspected of committing war crimes or atrocities in Europe
- the International Military Tribunal at Nuremberg
3. How to search for war crimes records at The National Archives
The best way to start is to search Discovery, our catalogue using keywords such as:
- war crimes
- war criminal
- Nuremberg trials
- United Nations War Crimes Commission or UNWCC
- Central Registry of War Criminals and Security Suspects or CROWCASS
Many war crimes records originated in the Foreign Office or the War Office, so you can refine your search to these collections, which have the letter codes FO and WO.
Not all relevant records will come up in an online search. In particular, Foreign Office political correspondence in FO 371 contains a lot of information about war crimes as does FO 1060 for 'minor' war crimes in the records of the legal divison of the Control Commission for Germany, but our catalogue does not provide full details.
To find out more about the contents of FO 371 in the period 1920-1951, use the printed index in the reading rooms at The National Archives at Kew, and look under the general heading 'War Criminals'.
