Balfour Declaration of 1926

The Balfour Declaration of 1926 was issued by the 1926 Imperial Conference of British Empire leaders in London. It was named after Arthur Balfour, who was Lord President of the Council. It declared the United Kingdom and the Dominions to be:

The Inter-Imperial Relations Committee, chaired by Balfour, drew up the document preparatory to its unanimous approval by the imperial prime ministers on 15 November 1926. It was first proposed by South African Prime Minister J. B. M. Hertzog and Canadian Prime Minister William Lyon Mackenzie King.

The declaration accepted the growing political and diplomatic independence of the Dominions in the years after World War I. It also recommended that the governors-general, the representatives of the King in each dominion, should no longer also serve automatically as the representative of the British government in diplomatic relations between the countries. In following years, high commissioners were gradually appointed, whose duties were soon recognised to be virtually identical to those of an ambassador. The first such British high commissioner was appointed to Canada in 1928.

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. In the statute, the British Parliament provided that it would not enact a law which applied to a Dominion as part of the law of that Dominion, unless the law expressly stated that the Dominion government had requested and consented to the enactment of that law.
