This is a guide to finding records of individual internees. During the First and Second World Wars both sides set up internment camps to hold enemy aliens – civilians who were believed to be a potential threat and have sympathy with the enemy’s war objectives. Internees were treated differently to prisoners of war and were given more privileges.

The National Archives does not hold registers of all internees. Very few records of individual internees survive for the First World War.

Records of enemy aliens and internees, First and Second World Wars

An array of records exist documenting people who were interned in the First and Second World Wars as well as of people who were exempted from internment. Many of these records are held within our Home Office collections (identified by catalogue references beginning HO) and are available online.

Search for the records of enemy aliens and internees in the First and Second World Wars by first and last name on and (£). You can also browse the same collections of enemy aliens and internees by year and by record series.

Among these online collections is the Aliens Department internees index, 1939–1947, drawn from record series HO 396. The index cards which make up this series (example below) provide more detail than any other single record on individual internees. They document mostly Germans, Austrians and Italians, as well as their spouses, interned or considered for internment by tribunals during the Second World War. Most of the cards were originally issued in September 1939 when the first round of decisions on internment were made. They were reused for later tribunals that took place in the early 1940s when larger numbers of resident aliens were interned following panic in Britain about the course the war was taking. Those interned included Jewish refugees who had escaped Nazi persecution.

They contain personal details on the front and sometimes information about the individual’s case on the reverse. Access to records of individuals who were interned is partially restricted, with only the front of the internment card open to access without restriction (you can request the opening of restricted records under the Freedom of Information Act 2000 by filling out our Freedom of Information enquiry form or by writing to our Records Enquiry Service at The National Archives, Kew, Richmond, Surrey TW9 4DU. Cards for aliens who were considered for internment but were not actually interned, also held in HO 396, are open without restriction.
