The history of the department dates back to the American Revolution, when the Second Continental Congress established the Board of War and Ordnance in 1776. The board was responsible for the administration of the Continental Army and was headed by John Adams, Thomas Jefferson, and Benjamin Franklin. After the Treaty of Paris was signed in 1783, the department was reorganized and became the Department of War in 1789. The department played a significant role in the Indian Wars, Quasi-War, and the Barbary Wars, working closely with George Washington, Thomas Jefferson, and James Madison. The department also worked with the United States Department of State and the United States Department of the Treasury to negotiate treaties such as the Treaty of Ghent and the Adams-Onís Treaty.
The department was headed by the Secretary of War, who was a member of the Cabinet of the United States. The secretary was responsible for the administration of the department and reported directly to the President of the United States. The department was organized into several bureaus, including the Adjutant General's Office, Quartermaster Corps, and the Ordnance Department. The department worked closely with other government agencies, such as the United States Department of the Interior, United States Department of Agriculture, and the United States Department of Commerce. The department also had a close relationship with the National Guard Bureau, United States Army Corps of Engineers, and the United States Military Academy.
