July 4, also known as Independence Day, marks the day the Declaration of Independence was adopted and the 13 North American colonies officially separated from Great Britain. As the Fourth of July draws nearer, here's a brief rundown of what happened that day in 1776, approximately 249 years ago.

On a hot, steamy day in Philadelphia, a group of delegates to the Continental Congress gathered to celebrate the final approval of the Declaration of Independence.

Many are grabbing their lighters to ignite sparklers and fireworks for the Fourth of July, but still do not know the history of why Americans celebrate the holiday with light shows.
