passage: Member states of the Commonwealth of Nations
The Commonwealth was first officially formed in 1931 when the Statute of Westminster gave legal recognition to the sovereignty of dominions. Known as the "British Commonwealth", the original members were the United Kingdom, Canada, Australia, New Zealand, South Africa, Irish Free State, and Newfoundland, although Australia and New Zealand did not adopt the statute until 1942 and 1947 respectively.[4] In 1949, the London Declaration was signed and marked the birth of the modern Commonwealth and the adoption of its present name.[5] The newest member is Rwanda, which joined on 29 November 2009.[6] The most recent departure was the Maldives, which severed its connection with the Commonwealth on 13 October 2016.
passage: Commonwealth of Nations
The Commonwealth developed from the imperial conferences. A specific proposal was presented by Jan Smuts in 1917 when he coined the term "the British Commonwealth of Nations" and envisioned the "future constitutional relations and readjustments in essence" at the Paris Peace Conference of 1919 by delegates from the Dominions as well as Britain.[11][12] The term first received imperial statutory recognition in the Anglo-Irish Treaty of 1921, when the term British Commonwealth of Nations was substituted for British Empire in the wording of the oath taken by members of parliament of the Irish Free State.[13]
