The Secretary of State for Commonwealth Relations was a British Cabinet office existing between 1947 and 1966, responsible for dealing with British relationship with members of the Commonwealth of Nations (its former colonies). The position was created out of the old position of Secretary of State for Dominion Affairs. In 1966, the position was merged with that of the Secretary of State for the Colonies to form that of Secretary of State for Commonwealth Affairs, which was in turn merged with the Secretary of State for Foreign Affairs in 1968 to create the new position of Secretary of State for Foreign and Commonwealth Affairs.
