The correct answer is: September 3, 1783.

Explanation:

On September 3, 1783, by signing the Treaty of Paris, the American Revolutionary War was officially ended, resulting in American independence. The Revolution was ended when General Cornwallis surrendered the British position at Yorktown, Virginia in October 1781. Two years later, the Treaty of Paris officially announced the independence of America. The Treaty was signed by representatives of King George III (Great Britain) and representatives of the U.S.

The Revolutionary War (1775 – 1783) arose from growing tensions between Thirteen North American colonies and the colonial government under the British crown. The Revolution was caused by colonial opposition to the British government and their attempts to impose control over the colonies. The other reasons for Revolution include many taxes and laws imposed on the colonies, French and Indian War, Boston Blockade, etc.
