The Royal Institute of International Affairs, known as Chatham House, is a prominent British think tank in London, England. Pioneering the renowned Chatham House Rule, the institute, headquartered at the historically significant 10 St James’s Square, embodies a mission to cultivate a sustainably secure, prosperous, and just world.

Historical Significance and Chatham House Rule:

With historical roots designed in part by Henry Flitcroft, this iconic building gained prominence through the philanthropic donation of Canadian Lieutenant-Colonel Reuben Wells Leonard and Kate Rowlands Leonard in 1923. As the central hub for impactful initiatives, Chatham House opens its membership to individuals, corporations, academic institutions, and NGOs, fostering a diverse community dedicated to international affairs. As a pioneer in shaping discussion norms, Chatham House introduced the Chatham House Rule, a non-attribution guideline encouraging open dialogue on contentious topics while maintaining confidentiality. This rule is crucial for facilitating candid discussions on sensitive issues, even though most meetings are recorded.
