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 being established within a few weeks of each other in 1789.
Federal executive departments are analogous to ministries common in parliamentary or semi-presidential systems but, with the United States being a presidential system, their heads otherwise equivalent to ministers, do not form a government (in a parliamentary sense) nor are they led by a head of government separate from the head of state. The heads of the federal executive departments, known as secretaries of their respective department, form the traditional Cabinet, an executive organ that serves at the disposal of the president and normally act as an advisory body to the presidency.
Since 1792, by statutory specification, the cabinet constituted a line of succession, after the Speaker of the House and the president pro tempore of the Senate to the presidency in the event of a vacancy in both that office 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.
