The oldest branch of the United States military is the United States Army, established on June 14, 1775, by the Second Continental Congress during the American Revolutionary War. This date marks the official founding of the Continental Army, with George Washington appointed as its commander-in-chief. The Army’s creation predates the formal establishment of the United States as an independent nation, reflecting its critical role in securing the country’s freedom from British rule.
Historical Context and Evolution

Its establishment was a pivotal moment in American history, as it marked the colonies' collective decision to unite militarily against a common enemy. After the Revolutionary War, the Continental Army was disbanded in 1783, but its legacy was carried forward by the creation of the United States Army under the Constitution in 1789.
