Commanding General of the United States Army

Prior to the institution of the Chief of Staff of the United States Army in 1903, there was generally a single senior-most officer in the army. From 1783, he was known simply as the Senior Officer of the United States Army, but in 1821, the title was changed to Commanding General of the United States Army. The position was abolished with the creation of the Chief of Staff of the United States Army in 1903.
