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 Treaty of Paris of 1783 (which ended the American Revolutionary War), and facilitated ten years of peaceful trade between the United States and Britain in the midst of the French Revolutionary Wars, which began in 1792. The Treaty was designed by Alexander Hamilton and supported by President George Washington. It angered France and bitterly divided Americans. It inflamed the new growth of two opposing parties in every state, the pro-Treaty Federalists and the anti-Treaty Jeffersonian Republicans.

The Treaty was negotiated by John Jay and gained many of the primary American goals. This included the withdrawal of British Army units from forts in the Northwest Territory that it had refused to relinquish under the Paris Peace Treaty. The British were retaliating for the United States reneging on Articles 4 and 6 of the 1783 treaty; American state courts impeded the collection of debts owed British creditors and upheld the continued confiscation of Loyalist estates in spite of an explicit understanding that the prosecutions would be immediately discontinued. The parties agreed that disputes over wartime debts and the AmericanCanadian boundary were to be sent to arbitrationone of the first major uses of arbitration in modern diplomatic history. This set a precedent used by other nations. The Americans were granted limited rights to trade with British colonies in the Caribbean in exchange for some limits on the American export of cotton.

The Jay treaty was signed on November 19, 1794, during the thermidorian reaction in France, and submitted to the United States Senate for its advice and consent the following June. It was ratified by the Senate on June 24, 1795, by a two-thirds majority vote of 2010 (exactly the minimum number necessary for concurrence). It was also ratified by the British government, and took effect February 29, 1796, the day when ratifications were officially exchanged.

The treaty was hotly contested by Jeffersonians in each state. An effort was made to block it in the House, which ultimately failed. The Jeffersonians feared that closer economic or political ties with Great Britain would strengthen Hamilton's Federalist Party, promote aristocracy, and undercut republicanism. This debate crystallized the emerging partisan divisions and shaped the new "First Party System", with the Federalists favoring the British and the Jeffersonian republicans favoring France. The treaty was for ten years' duration. Efforts failed to agree on a replacement treaty in 1806 when Jefferson rejected the MonroePinkney Treaty, as tensions escalated toward the War of 1812.

Detroit (, locally also ; French: Détroit) is the largest city in the U.S. state of Michigan. It is also the largest U.S. city on the United States–Canada border, and the seat of government of Wayne County. The city of Detroit had a population of 639,111 at the 2020 census, making it the 27th-most populous city in the United States. The metropolitan area, known as Metro Detroit, is home to 4.3 million people, making it the second-largest in the Midwest after the Chicago metropolitan area, and 14th-largest in the United States. Regarded as a major cultural center, Detroit is known for its contributions to music and as a repository for art, architecture and design, along with its historical automotive background.Detroit is a major port on the Detroit River, one of the four major straits that connect the Great Lakes system to the Saint Lawrence Seaway. The City of Detroit anchors the second-largest regional economy in the Midwest, behind Chicago and ahead of Minneapolis–Saint Paul, and the 14th-largest in the United States. Detroit is best known as the center of the U.S. automobile industry, and the "Big Three" auto manufacturers General Motors, Ford, and Stellantis North America are all headquartered in Metro Detroit. As of 2007, the Detroit metropolitan area is the number one exporting region among 310 defined metropolitan areas in the United States. The Detroit Metropolitan Airport is among the most important hubs in the United States. Detroit and its neighboring Canadian city Windsor are connected through a highway tunnel, railway tunnel, and the Ambassador Bridge, which is the second-busiest international crossing in North America, after San Diego–Tijuana.In 1701, Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit, the future city of Detroit. During the late nineteenth and early twentieth century, it became an important industrial hub at the center of the Great Lakes region. The city's population became the fourth-largest in the nation in 1920, after only New York City, Chicago and Philadelphia, with the expansion of the auto industry in the early 20th century. As Detroit's industrialization took off, the Detroit River became the busiest commercial hub in the world. The strait carried over 65 million tons of shipping commerce through Detroit to locations all over the world each year; the freight throughput was more than three times that of New York and about four times that of London. By the 1940s, the city's population remained the fourth-largest in the country. However, due to industrial restructuring, the loss of jobs in the auto industry, and rapid suburbanization, among other reasons, Detroit entered a state of urban decay and lost considerable population from the late 20th century to the present. Since reaching a peak of 1.85 million at the 1950 census, Detroit's population has declined by more than 65 percent. In 2013, Detroit became the largest U.S. city to file for bankruptcy, which it successfully exited in December 2014, when the city government regained control of Detroit's finances.Detroit's diverse culture has had both local and international influence, particularly in music, with the city giving rise to the genres of Motown and techno, and playing an important role in the development of jazz, hip-hop, rock, and punk. The rapid growth of Detroit in its boom years resulted in a globally unique stock of architectural monuments and historic places. Since the 2000s conservation efforts have managed to save many architectural pieces and achieved several large-scale revitalizations, including the restoration of several historic theatres and entertainment venues, high-rise renovations, new sports stadiums, and a riverfront revitalization project. More recently, the population of Downtown Detroit, Midtown Detroit, and various other neighborhoods have increased. An increasingly popular tourist destination, Detroit receives 19 million visitors per year. In 2015, Detroit was named a "City of Design" by UNESCO, the first U.S. city to receive that designation.
