The Commonwealth Foundation (CF) is an intergovernmental organisation that was established by the Commonwealth Heads of Government in 1966, a year after its sister organisation, the Commonwealth Secretariat. The Foundation is located at Marlborough House in London, a former royal palace which was assigned for the use of these Commonwealth institutions by Her Majesty Queen Elizabeth II, the Head of the Commonwealth. As the Commonwealth agency for civil society, the Foundation is funded by 49 member states to support participatory governance through its programmes. The Foundation provides resources, grants and access to platforms to encourage better engagement between civil society and institutions of governance. Membership of the Commonwealth Foundation is voluntary and is separate from membership of the Commonwealth of Nations.
