In 1884, while visiting Australia, Lord Rosebery described the changing British Empire, as some of its colonies became more independent, as a 'Commonwealth of Nations'. Conferences of British and colonial prime ministers had occurred periodically since the first one in 1887, leading to the creation of the Imperial Conferences in 1911. The commonwealth developed from the Imperial Conferences. A specific proposal was presented by Jan Christiaan Smuts in 1917 when he coined the term 'the British Commonwealth of Nations,' and envisioned the 'future constitutional relations and readjustments in the British Empire'. Smuts successfully argued that the Empire should be represented at the all-important Versailles Conference of 1919 by delegates from the dominions as well as Britain. In the Balfour Declaration at the 1926 Imperial Conference, Britain and its dominions agreed they were 'equal in status, in no way subordinate one to another in any aspect of their domestic or external affairs, though united by common allegiance to the Crown, and freely associated as members of the British Commonwealth of Nations'.
