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.
Ratification Day in the United States is the anniversary of the congressional proclamation of the ratification of the Treaty of Paris, on January 14, 1784, at the Maryland State House in Annapolis, Maryland, by the Confederation Congress, which marked the official end of the American Revolutionary War.
The Treaty of Paris, signed in Paris by representatives of King George III of Great Britain and representatives of the United States on September 3, 1783, officially ended the War of American Independence and recognized the Thirteen Colonies, which had been part of colonial British America, to be free, sovereign and independent states.
Great Britain, also known as the Kingdom of Great Britain, was a sovereign state in Western Europe from 1707 to the end of 1800. The state was created by the 1706 Treaty of Union and ratified by the Acts of Union 1707, which united the Kingdom of England and the Kingdom of Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands, with the exception of the Isle of Man and the Channel Islands. The unitary state was governed by a single parliament at the Palace of Westminster, but distinct legal systems—English law and Scots law—remained in use, as did distinct educational systems and religious institutions, namely the Church of England and the Church of Scotland remaining as the national churches of England and Scotland respectively.
January 14 is the 14th day of the year in the Gregorian calendar; 351 days remain until the end of the year.
