The U.S. Army was founded on June 14, 1775, when the Continental Congress authorized the creation of the Continental Army to fight the British. This makes it the oldest branch of the U.S. military, predating the Declaration of Independence by over a year. The Army Birthday is celebrated annually on June 14, coinciding with Flag Day.
The United States Army was born on June 14, 1775, when the Second Continental Congress passed a resolution to raise armed forces to defend the American colonies against British aggression. This action created the Continental Army, with George Washington appointed as its commander-in-chief the following day. The establishment of the Army marked a pivotal step toward American independence, unifying colonial militias under a single command structure.
Over the centuries, the Army has evolved from a small, temporary force into a permanent, professional military organization. The Army Birthday was first officially celebrated in 1861, during the Civil War, and has since become a tradition. Modern celebrations include military ceremonies, parades, and public events at Army installations worldwide. The day is also used to honor the service and sacrifice of soldiers, past and present, and to highlight the Army's role in national security.
