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 these records of enemy aliens and internees in the First and Second World Wars by first and last name on Findmypast.co.uk (£). You can also browse the same collections of enemy aliens and internees by year and by record series, as an alternative way of searching.
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.
An Exemption From Internment Card (catalogue reference HO 396/180/00136). The card shows that although the person in question was exempted from internment in 1939, a decision was then made in 1940 to intern the individual, whose release was then authorised in 1941.
