Variously known as the Fourth of July and Independence Day, July 4th has been a federal holiday in the United States since 1941, but the tradition of Independence Day celebrations goes back to the 18th century and the American Revolution (1775-83).
In June 1776, representatives of the 13 colonies then fighting in the revolutionary struggle weighed a resolution that would declare their independence from Great Britain. On July 2nd, the Continental Congress voted in favor of independence, and two days later its delegates adopted the Declaration of Independence, a historic document drafted by Thomas Jefferson.
Falling in mid-summer, the Fourth of July has since the late 19th century become a major focus of leisure activities and a common occasion for family get-togethers, often involving fireworks and outdoor barbecues. The most common symbol of the holiday is the American flag, and a common musical accompaniment is “The Star-Spangled Banner,” the national anthem of the United States.
