Initially, both the Americans and the British saw the conflict as a kind of civil war within the British Empire: To King George III it was a colonial rebellion, and to the Americans it was a struggle for their rights as British citizens.
However, Parliament remained unwilling to negotiate with the American rebels and instead purchased German mercenaries to help the British army crush the rebellion. In response to Britain’s continued opposition to reform, the Continental Congress began to pass measures abolishing British authority in the colonies.
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 Revolutionary War 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.
