The United States takes possession of Detroit from Great Britain under terms of the Jay Treaty.

Detroit is the most populous city in the U.S. state of Michigan. It is situated on the bank of the Detroit River across from the Canadian city of Windsor, Ontario. It is the 26th-most populous city in the United States and the largest U.S. city on the Canada–United States border with a population of 639,111 at the 2020 census, while the Metro Detroit area at over 4.4 million people is the 14th-largest metropolitan area in the nation and second-largest in the Midwest. The county seat of Wayne County, Detroit is a significant cultural center known for its contributions to music, art, architecture and design, in addition to its historical automotive and industrial background.

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.

The Treaty of Amity, Commerce, and Navigation, Between His Britannic Majesty and the United States of America, commonly known as the Jay Treaty, and also as Jay's Treaty, was a 1794 treaty between the United States and Great Britain that averted war, resolved issues remaining since the 1783 Treaty of Paris, and facilitated ten years of peaceful trade between Americans and the British in the midst of the French Revolutionary Wars, which had begun in 1792. For the Americans, the treaty's policy was designed by Treasury secretary Alexander Hamilton, supported by President George Washington. It angered France and bitterly divided American public opinion, encouraging the growth of two opposing American political parties, the pro-Treaty Federalists and the anti-Treaty Democratic-Republicans.
