The International Institute for Strategic Studies (IISS) is a globally renowned authority on political-military conflict, geopolitical trends, and international security. Headquartered in London, the IISS provides objective, fact-based research, analysis, and insights to governments, businesses, media, and the wider public. Key activities include publishing influential works like 'The Military Balance' and 'Strategic Survey', convening high-level dialogues such as the IISS Shangri-La Dialogue and IISS Manama Dialogue, and conducting detailed research programs on critical security challenges.
The London headquarters serves as the central hub for IISS's global research operations, publications, strategic communications, and the organization of its major international dialogues and events. It houses the majority of its research staff and administrative functions.
Arundel House is a prominent historic building located on the Victoria Embankment, overlooking the River Thames. It provides a prestigious and accessible location for meetings, research, and events.
The work culture at IISS HQ is characterized by intellectual rigor, collaboration among international experts, a fast-paced environment driven by global events, and a commitment to objectivity and non-partisanship in its analysis.
The London HQ is the birthplace and nerve center of the IISS, establishing its global reputation and coordinating its worldwide network of offices and experts. Its location in a major global city facilitates engagement with policymakers, diplomats, and academics.
The IISS operates globally, with key functions supported across its international offices. Core research, analysis, and major publications are driven from London but enriched by regional expertise from offices in Singapore (Asia-Pacific), Manama (Middle East), Washington D.C. (Americas), and Berlin (Europe). These offices also spearhead regional engagement, host influential security dialogues (Shangri-La Dialogue, Manama Dialogue), and disseminate IISS analysis to a worldwide audience, ensuring a truly global perspective on security issues.
