On June 14, 1775, in the middle of the American Revolutionary War, the Continental Congress decided that to better organize the fight against the British, the colonies should all be unified under one force. Thus, the American Continental Army was founded. Now, every year, in the United States, people celebrate the Army's Birthday on June 14.
Army Birthday is not a federal holiday, so businesses and schools remain open.
When the American revolutionary war started on April 1775, the fighters that enlisted to fight the British forces were militia groups paid and equipped by the colonies, but without any organization, command or strategy. Different groups fought under different banners which didn't give the American side of the war a sense of unity against the common enemy.
In June, while a battle in Boston was approaching, it became clear that Congress should find a solution for the militia strategy, which wasn't working. After the Committee of the Whole reached a consensus, the American Continental Army was created, with George Washington as its commander.
This allowed riflemen to enlist and serve in the army, and a committee was appointed to create the rules and regulations for said army. The first branch of the American military to be founded on that day was the Infantry. Over the year, the U.S. Army has significantly expanded its forces.
The first Army service training program for new recruits took place between 1777 and 1778. In 1787, with the signing of the United States Constitution, it became defined that the acting President of the United States also acts as the Commander-in-Chief for the army.
With the United States Declaration of Independence only having been enacted on July 4, 1776, this means that the American army is older than the country it serves.
How Army Birthday is celebrated
Branches of the Army usually celebrate Army Birthday on their base, by organizing special events such as having their families visit for celebratory lunches and dinners and holding commemorative ceremonies.
Around the U.S. Military bases of the world, there is the Army Birthday Ball, a black-tie event where attendees pay their respects for those who lost their lives serving in the U.S. Army and also welcome the newest recruits.
