History

The U.S. Constitution, drafted in Philadelphia, Pennsylvania in 1787 and ratified by the states the following year, gave the President the responsibility for the conduct of the nation's foreign relations. It soon became clear, however, that an executive department was necessary to support the President in the conduct of the affairs of the new federal government.

The House of Representatives and Senate approved legislation to establish a Department of Foreign Affairs on July 21, 1789, and President Washington signed it into law on July 27, making the Department of Foreign Affairs the first Federal agency to be created under the new Constitution. This legislation remains the basic law of the Department of State. In September 1789, additional legislation changed the name of the agency to the Department of State and assigned to it a variety of domestic duties.

President George Washington signed the new legislation on September 15. Most of these domestic duties of the Department of State were eventually turned over to various new Federal departments and agencies that were established during the 19th century.

On September 29, 1789, President Washington appointed Thomas Jefferson of Virginia, then Minister to France, to be the first United States Secretary of State, although John Jay had been serving in that capacity as a holdover from the Confederation since before Washington had taken office and would continue in that capacity until Jefferson would return from Europe many months later.
