The Royal Institute of International Affairs, also known as Chatham House, is one of the world's leading institutes for the analysis of international issues. Founded in 1920, the Institute works to stimulate debate and research on political, business, security and other key issues in the international arena. It does this through its research, meetings, conferences and publications as well as through its library and information centre and expert interviews for the media. The Chatham House Rule, used worldwide to allow for free speech and confidentiality at meetings, originated here. The Institute has a presence in the USA, where the Chatham House Foundation exists to promote support for Anglo-American relations, and to make the Institute more accessible to an American audience.
