Independence Day, commonly called Fourth of July, has been a federal holiday in the United States since 1941.
On June 1776, representatives of the 13 colonies fought in the American Revolutionary War and then declared their independence from Great Britain.
According to History.com, the Continental Congress voted on July 2 which many argue that the celebration of freedom should be on that day. The Declaration of Independence, a historic document drafted by Thomas Jefferson, was adopted two days later on the Fourth of July.
Since the day independence was declared, Fourth of July has been celebrated as the birth of American independence, with festivities ranging from fireworks and parades to more casual family gatherings and barbecues.
