The Balfour Declaration of 1926 was a report by the Committee on Inter-Imperial Relations at the 1926 Imperial Conference in London that clarified a new relationship between Great Britain and the Dominions of Canada, South Africa, Australia, New Zealand, and the Irish Free State. The report declared that Britain and its Dominions were constitutionally equal to each other, and it defined the group of self-governing communities composed of Great Britain and the Dominions as "autonomous Communities within the British Empire, equal in status, in no way subordinate one to another in any aspect of their domestic or external affairs, though united by a common allegiance to the Crown, and freely associated as members of the British Commonwealth of Nations". The conclusions of the Imperial Conference of 1926 were re-stated by the 1930 conference and incorporated in the Statute of Westminster of December 1931. The Balfour Declaration of 1926 was named after Arthur Balfour, who was Lord President of the Council and chaired the Inter-Imperial Relations Committee that drew up the document.
