The United States Army was officially founded on June 14, 1775, when the Second Continental Congress passed a resolution to establish the Continental Army as a unified colonial fighting force against the British during the American Revolutionary War. This date marks the birth of the U.S. Army as the first national institution of America. George Washington was appointed as its commander the following day, June 15, 1775. After the Revolutionary War, the Continental Army was disbanded, and on June 3, 1784, the United States Army was created to replace it as the standing army of the nation. Thus, the key founding dates are:
- Continental Army: June 14, 1775
- United States Army in its current form: June 3, 1784.
