The International Institute for Strategic Studies (IISS) is an international research institute or think tank focusing on defence and security issues. Since 1997, its headquarters have been at Arundel House in London.[1] It has offices on four continents, producing data and research on questions of defence, security and global affairs, publishing publications and online analysis, and convening major security summits.[2] The Guardian newspaper has described the IISS as ‘one of the world’s leading security think tanks.’[3]

The current Director-General and Chief Executive is Bastian Giegerich while Sir John Chipman is the Executive Chairman.

The 2017 Global Go To Think Tank Index ranked IISS as the tenth-best think tank worldwide and the second-best Defence and National Security think tank globally,[4] while Transparify ranked it third-largest UK think tank by expenditure, but gave it its lowest rating, "deceptive", on funding transparency.[5]



The institute has worked with governments, defence ministries and global organisations such as NATO.[6]

Advisory services


The IISS provides ‘strategic advice and political risk analysis to government and commercial clients’.[7]



In 2011 the institute published the FARC files[8]—documents captured from the Revolutionary Armed Forces of Colombia that shed light on the movement's inner workings.

The 2017 Global Go To Think Tank Index ranked the Shangri-La Dialogue as the best Think tank conference worldwide.[9]



The Institute for Strategic Studies (ISS), as it was originally known, was founded in 1958, following a conference in January 1957, which gathered together the main voices interested in the nuclear issues of the day. Military historian Michael Howard chaired a group which recommended that ‘we should set up a body whose primary  purpose should be the collection and dissemination of information about nuclear weapons and their implications for international relations…And so the Institute was born.’

Its first director was the defence journalist Alastair Buchan, and its first president the former Labour prime minister Clement Attlee.

While the Institute’s initial composition was mainly British, from 1968 the council were joined by Australian and Japanese members. Because of this, it was renamed the International Institute for Strategic Studies (IISS) in 1971.

Since then, the IISS has convened many private discussion groups and conferences and also hosted influential public events and lectures. The 1977 Alastair Buchan memorial lecture, delivered by West German Chancellor Helmut Schmidt (an Institute member since 1959), which became known as one of the key appeals for ‘Euromissiles’ to counter new Soviet intermediate-range missiles.

In 2016, The Guardian reported that IISS "has been accused of jeopardising its independence after leaked documents showed it has secretly received £25m from the Bahraini royal family", noting that leaked "documents reveal that IISS and Bahrain's rulers specifically agreed to keep the latter's funding for the Manama Dialogues secret".[10][11] The IISS did not dispute the authenticity of the leaked documents or deny receiving funding from Bahrain, but issued a response stating that "[a]ll IISS contractual agreements, including those with host governments, contain a clause asserting the institute's absolute intellectual and operational independence as an international organisation that does not participate in any manner of advocacy".[12]

Peter Oborne in Middle East Eye subsequently reported that IISS may have received nearly half of its total income from Bahraini sources in some years.[13]

The IISS moved to new headquarters at Arundel House in 2000. In 2023, the IISS had approximately 160 employees and an annual turnover of more than £25 million.

Raymond L. Garthoff wrote in 2004:[14]

In 1959 the IISS issued a pamphlet on the "military balance" between the Soviet Union and NATO. It was unfortunately replete with errors, having been put together from published sources of widely varying quality. I called this to the attention of Alastair Buchan, the director of the institute, who was quite disturbed. A new version was issued in November 1960, much more correct and accurate, though still not up to the latest intelligence. Again, I called this to Buchan's attention, and he undertook to check out with British authorities what became annual issuances.





The IISS is a registered charity, and fundraising is overseen by the Board of Trustees.
