The Fourth of July — also known as Independence Day or 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. On July 2nd, 1776, the Continental Congress voted in favor of independence, and two days later delegates from the 13 colonies adopted the Declaration of Independence, a historic document drafted by Thomas Jefferson. From 1776 to the present day, July 4th has been celebrated as the birth of American independence, with festivities ranging from fireworks, parades and concerts to more casual family gatherings and barbecues.
When the initial battles in the Revolutionary War broke out in April 1775, few colonists desired complete independence from Great Britain, and those who did were considered radical. By the middle of the following year, however, many more colonists had come to favor independence, thanks to growing hostility against Britain and the spread of revolutionary sentiments. On June 7, when the Continental Congress met at the Pennsylvania State House (later Independence Hall) in Philadelphia, the Virginia delegate Richard Henry Lee introduced a motion calling for the colonies’ independence. Amid heated debate, Congress postponed the vote on Lee’s resolution, but appointed a five-man committee - including Thomas Jefferson of Virginia, John Adams of Massachusetts, Roger Sherman of Connecticut, Benjamin Franklin of Pennsylvania and Robert R. Livingston of New York—to draft a formal statement justifying the break with Great Britain.
On July 2nd, the Continental Congress voted in favor of Lee’s resolution for independence in a near-unanimous vote (the New York delegation abstained, but later voted affirmatively). On that day, John Adams wrote to his wife Abigail that July 2 “will be celebrated, by succeeding Generations, as the great anniversary Festival” and that the celebration should include “Pomp and Parade…Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other.”
On July 4th, the Continental Congress formally adopted the Declaration of Independence, which had been written largely by Jefferson. Though the vote for actual independence took place on July 2nd, from then on the 4th became the day that was celebrated as the birth of American independence.
