The United States Army is the largest branch of the United States Armed Forces and performs land-based military operations. It is one of the seven uniformed services of the United States. As the largest and senior branch of the U.S. military, the modern U.S. Army has its roots in the Continental Army, which was formed to fight the American Revolutionary War before the U.S. was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784, to replace the disbanded Continental Army. The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775.
