The Declaration of Independence
In January 1776, Thomas Paine published Common Sense, an influential political pamphlet that convincingly argued for American independence and sold more than 500,000 copies in a few months. In the spring of 1776, support for independence swept the colonies, the Continental Congress called for states to form their own governments, and a five-man committee was assigned to draft a declaration.
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 approved it on July 19. On August 2, the declaration was signed.
The American War for Independence would last for five more 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. In 1783, with the signing of the Treaty of Paris with Britain, the United States formally became a free and independent nation.
Coincidentally, Jefferson and Adams both died on July 4, 1826, 50 years after the Declaration of Independece was approved.
