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.

Known now as a day of patriotism and enjoying time off from work, the Fourth of July began the journey to becoming a quintessential American holiday in 1776, when the Second Continental Congress adopted the Declaration of Independence.

In Huntington Beach, some parade-goers staked out their prime spots before dawn today to watch the famed march down Main Street, this year celebrating 121 years. The event is dubbed the biggest Fourth of July parade west of the Mississippi River.
