Imperial Conferences (Colonial Conferences before 1907) were periodic gatherings of government leaders from the self-governing colonies and dominions of the British Empire between 1887 and 1937, before the establishment of regular Meetings of Commonwealth Prime Ministers in 1944. They were held in 1887, 1894, 1897, 1902, 1907, 1911, 1921, 1923, 1926, 1930, 1932 and 1937.
All the conferences were held in London, the United Kingdom, the seat of the Empire, except for the 1894 and 1932 conferences which were held in Ottawa, the capital of the most senior dominion. The 1907 conference changed the name of the meetings to Imperial Conferences and agreed that the meetings should henceforth be regular rather than taking place while overseas statesmen were visiting London for royal occasions (e.g. jubilees and coronations).
Originally instituted to emphasise imperial unity, as time went on, the conferences became a key forum for dominion governments to assert the desire for removing the remaining vestiges of their colonial status. The conference of 1926 agreed to the Balfour Declaration, which acknowledged that the dominions would henceforth rank as equals to the United Kingdom, as members of the 'British Commonwealth of Nations'.
