With the Federation dissolved, Barbados reverted to its former status, that of a self-governing colony. The island negotiated its own independence at a constitutional conference with Britain in June 1966. After years of peaceful and democratic progress, Barbados finally became an independent state on 30 November 1966, with Errol Barrow its first Prime Minister, although Queen Elizabeth II remained the monarch. Upon independence Barbados maintained historical linkages with Britain by becoming a member of the Commonwealth of Nations. A year later, Barbados' international linkages were expanded by obtaining membership of both the United Nations and the Organization of American States.
