American Revolutionary War: British forces led by Lord Cornwallis officially surrendered to Franco-American forces under George Washington and the comte de Rochambeau, ending the Siege of Yorktown.

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war. But Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war in the Treaty of Paris two years later, in 1783, in which the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.

Charles Cornwallis, 1st Marquess Cornwallis was a British Army officer, Whig politician and colonial administrator. In the United States and United Kingdom, he is best known as one of the leading British general officers in the American War of Independence. His surrender in 1781 to a combined Franco-American force at the siege of Yorktown ended significant hostilities in North America. Cornwallis later served as a civil and military governor in Ireland, where he helped to bring about the Act of Union; and in India, where he helped to enact the Cornwallis Code and the Permanent Settlement.

George Washington was a Founding Father and the first president of the United States, serving from 1789 to 1797. As commander of the Continental Army, Washington led Patriot forces to victory in the American Revolutionary War against the British Empire. He is commonly known as the Father of the Nation for his role in bringing about American independence.
