The U.S. Department of the Interior was made a United States cabinet in 1849, at a time when the U.S. cabinet was small.[1][2] The Secretary of the Interior joined the President, Vice President , Secretary of War, Secretary of State, and Treasury Secretary.
The new department was sometimes colloquially called "The Department of Everything Else", and included loosely related agencies responsible for things like relations with Native Americans, land management, the US census.[2]
