# Secretary of State for Dominion Affairs

The position of secretary of state for dominion affairs was a secretary of state in the Government of the United Kingdom, responsible for British relations with the Empire’s dominions – Canada, Australia, New Zealand, South Africa, Newfoundland, and the Irish Free State – and the self-governing Crown colony of Southern Rhodesia.
When initially created in 1925, the office was held in tandem with that of Secretary of State for the Colonies; this arrangement persisted until June 1930. On two subsequent occasions the offices were briefly held by the same person.
The secretary of state was supported by an Under-Secretary of State for Dominion Affairs. In 1947, the name of the office was changed to the Secretary of State for Commonwealth Relations.
