Chatham House

Chatham House is a London-based independent policy institute founded in 1920. It is best known for the Chatham House Rule, a widely adopted protocol for confidential discussions that allows participants to use information shared but not attribute it to speakers or their organizations. The organization convenes government officials, academics, business leaders, and civil society figures to debate major international policy issues including security, economics, energy, and global governance.

The institute conducts research, hosts conferences and seminars, and publishes analysis on pressing global challenges. It maintains strict independence from government and corporate influence, operating as a registered charity. Chatham House has become one of the world's most influential think tanks, with its rule adopted by thousands of conferences and meetings globally as a standard for encouraging candid dialogue on sensitive topics.
