United States federal executive departments

The United States federal executive departments are among the oldest primary units of the executive branch of the federal government of the United States—the Departments of State, War, and the Treasury all having been established within a few weeks of each other in 1789.

Federal executive departments are analogous to president and normally act as an advisory body to the presidency.

Since 1792, by statutory specification, the cabinet constituted a line of succession to the presidency, after the Speaker of the House and the president pro tempore of the Senate, in the event of a vacancy in both the presidency and the vice presidency. The Constitution refers to these officials when it authorizes the President, in Article II, section 2, to "require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices." In brief, they and their organizations are the administrative arms of the President.
