The proud heritage of the Adjutant General Corps dates to the formation of the American Army, when on June 16, 1775, the Continental Congress established the position of Adjutant General on the staff of General George Washington. On June 17, 1775, Congress selected Horatio Gates, a former officer in the British Army, to become the first Adjutant General of the Army with the rank of Lieutenant General. He made good use of his knowledge of military organization by bringing good order and regularity to the Army by transforming militia units from the 13 colonies into one “American Army.”

On June 16, 2026, the Adjutant General Corps celebrated its 251st birthday. Over the course of its history, the Adjutant General Corps has assumed responsibility for several critical personnel and administrative support functions serving to sustain America’s Army in peace and war.
