It succeeded the First Continental Congress, which met between September 5, 1774 and October 26, 1774, also in Philadelphia. The second Congress managed the colonial war effort, and moved incrementally towards independence, adopting the United States Declaration of Independence on July 4, 1776.
The document, called the Declaration of Independence, was treasonous against the crown and the fifty-six men who signed it were in danger of being executed. Independence Day is celebrated on July 4 because that is the day when the Continental Congress adopted the final draft of the Declaration of Independence. From July 8, 1776, until the next month, the document was read publicly and people celebrated whenever they heard it.
