Royal United Services Institute

The Royal United Services Institute (RUSI) is the world’s oldest and the UK’s leading defence and security think tank. Our mission is to inform, influence and enhance public debate to help build a safer and more stable world. RUSI has been at the heart of military and security thinking for over 190 years, from the rise of the British Empire to its transformation and dissolution, through both World Wars and the Cold War. The Duke of Wellington and a number of other senior military commanders established the Institute in 1831, and some of the most influential thinkers in the 19th and 20th centuries worked or spoke at RUSI. The Institute is now documenting the ‘new disorder’ of the contemporary world, and it remains an intrinsic part of the research and debate that surrounds military and security thinking.
