American Revolutionary War: The war ends with the signing of the Treaty of Paris by the United States and the Kingdom of Great Britain.

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.

September 3 is the 246th day of the year in the Gregorian calendar; 119 days remain until the end of the year.
