The Declaration Of Independence was signed in Philadelphia in 1776.
On July 2, 1776, the Continental Congress voted to approve a Virginia motion calling for separation from Britain. The dramatic words of this resolution were added to the closing of the Declaration of Independence. Two days later, on July 4, the declaration was formally adopted by 12 colonies after minor revision. New York, the 13th colony, approved it on July 19. On August 2, the declaration was signed. The American War for Independence would last for five years. Yet to come were the Patriot triumphs at Saratoga, the bitter winter at Valley Forge, the intervention of the French and the final victory at Yorktown in 1781.
