In 1776, as every child has learned from school the Continental Congress drafted, edited and then signed the Declaration of independence.
Here's what they didn't tell you:
It was actually July 2, 1776 that the Continental Congress actually voted on freedom from Britain. The Declaration of Independence was a formality.
It was read out loud to the public in three locations: Philadelphia, PA; Trenton, NJ; Easton, PA on July 8, 1776.
The document was approved and went into effect on July 4th, but wasn't fully signed by all members of congress until August 2, 1776. The dispute arise from the fact that certain members weren't all present. Jefferson, Adams and Franklin recall it differently.
There were thought to be 200 copies of the Declaration of Independence. Today only 25 copies are known to exist.
