Chatham-Kent (2021 population: 104,316) is a single-tier municipality in Southwestern Ontario, Canada. It is mostly rural, and its population centres are Chatham, Wallaceburg, Tilbury, Blenheim, Ridgetown, Wheatley and Dresden. The current Municipality of Chatham-Kent was created in 1998 by the amalgamation of Blenheim, Bothwell, Camden, the City of Chatham, the Township of Chatham, Dover, Dresden, Erie Beach, Erieau, Harwich, Highgate, Howard, Orford, Raleigh, Ridgetown, Duart, Thamesville, Tilbury East, Tilbury, Wallaceburg, Wheatley and Zone.
 The Chatham-Kent census division, which includes the independent Delaware Nation at Moraviantown First Nation, had a population of 102,042 in the 2016 census.
 The area of Chatham-Kent is part of the traditional territory of the Odawa, Potawatomi, Ojibwe and Wyandot First Nations of Canada. After the Treaty of Paris in 1763 ceded control of the area from the French to the British, it became part of the Territory of Quebec. The title to the Chatham-Kent area was surrendered to the British as part of the 1790 McKee's Purchase, (named for Alexander McKee) to provide land for settlers. McKee's Purchase was designated an Event of National Historic Significance in Canada in 1931. A historical plaque for the purchase is located in Blenheim Park in Blenheim. Indigenous persons remain resident in the area today at the Delaware Nation at Moraviantown and Walpole Island First Nation.
 European settlement of the former city of Chatham area began with a naval dockyard in 1792, at the mouth of the Thames River. The town was named after William Pitt, 1st Earl of Chatham.  It was built as a naval dockyard, a characteristic shared by Chatham, Kent, England. In England, the name Chatham came from the British root ceto and the Old English ham thus meaning a forest settlement. Following the American Revolution and the Gnadenhutten massacre, a group of Christian Munsee settled in what is now the Moraviantown reserve. In the War of 1812, the Battle of the Thames took place between Moraviantown and Thamesville on October 5, 1813.
 During the 19th century, the area was the northern terminus of the Underground Railroad. As a result, Chatham-Kent is now part of the African-Canadian Heritage Tour. Josiah Henson Museum for African-Canadian History, formally known as Uncle Tom's Cabin Historic Site is a museum of the Dawn Settlement, established in 1841 by Josiah Henson near Dresden as refuge for the many slaves who escaped to Canada from the United States. John Brown, the abolitionist, planned his raid on the Harpers Ferry Arsenal in Chatham and recruited local men to participate in the raid. He held in Chatham a Convention of Colored Men on May 8–10, 1858. The small village of North Buxton, part of the African Canadian Heritage Tour, also played an important role in the Underground Railroad. By the 1850s, the city of Chatham was referred to as the "black mecca of Canada". A museum in the city, the Black Mecca Museum, still bears this name. Chatham was home to a number of black churches and business, with Black Canadians making up one-third of the city's population and controlling a significant portion of the city's political power. Nearby Dresden and Buxton were also home to thousands of land-owning black residents. However, after the abolition of slavery in the United States, many black families left the area. Today the city of Chatham is just 3.3% black, with Chatham-Kent as a whole being 2.1% black. Few of the black-owned institutions are still in operation.
 In 1846, the town of Chatham had a population of about 1,500, with part of the town being called Chatham North. There were four churches, a theatre, a weekly newspaper and a cricket club. The road between London and Amherstburg was open, and transportation by stagecoach was available. A fast boat also provided transportation to Detroit and Buffalo. Chatham had many tradesman, a foundry, two banks, three schools, a tavern and a library where one could read books and newspapers. By 1869, the population was 3,000 in this industrial area with several mills, foundries, and breweries; a great deal of wood was being produced. A steamboat offered transportation to Windsor and Detroit. There was one bank office.
 Between 1906 and 1909, the city was home to the Chatham Motor Car Company, and from 1919 to 1921, Denby Motor Truck Company of Canada. It was also where the Hyslop and Ronald steam fire engine manufacturer was located; the factory would be taken over by Chatham Motor Car. In addition, it hosted meat packer O'Keefe and Drew.
 The Hawaiian pizza is claimed to have been invented in Chatham in 1962 at the Satellite Restaurant by Sam Panopoulos. In the U.S., former Ohio Governor Jim Rhodes proposed building a bridge across Lake Erie linking Cleveland to the southern coast of Kent County.
 Before 1998, Kent County consisted of the townships of Camden, Chatham, Dover, Harwich, Howard, Orford, Raleigh, Romney, Tilbury East and Zone. In some of Canada's earliest post-Confederation censuses, some residences in Kent County were incorrectly reported as being in Bothwell "County", which was a separate electoral district comprising parts of Kent and Lambton counties but not a distinct county in its own right.
 In 1998, the County of Kent and the city of Chatham were amalgamated by the Province of Ontario to form the Municipality of Chatham–Kent. Most services were also combined. Since then, bus service has begun to serve all of Chatham-Kent. Starting in 2007, routes were set up to include the former towns of Wallaceburg and Dresden. Before 1998, each town had their own fire department. It then became the Chatham-Kent Fire Department upon amalgamation. The county also had separate police departments until 1998. The city of Chatham, as well as the towns of Wallaceburg, Dresden, and Tilbury, each had their own departments. The Chatham-Kent Police Service was formed on September 1, 1998. Many residents opposed amalgamation, as 18 city councillors boycotted the official vote, and the final decision to amalgamate was imposed on the County by a provincial commissioner. In a study on amalgamations in Ontario from 2003, 48% of respondents in Chatham-Kent felt the value they received as taxpayers became worse after amalgamation, and 64% of respondents still did not think of the community as "the Municipality of Chatham-Kent."
 Chatham-Kent has many historic festivals throughout the year, such as the Battle of Longwoods reenactment, which takes place on Labour Day weekend at Fairfield Museum on Longwoods Road. Chatham Kent is also home to many historic buildings which are part of an annual ghost tour offered each year at Halloween. The participants go on a guided walk of downtown while the guide informs them of various ghost stories tied to the local buildings in which they pass. Chatham-Kent was a major part of the Underground Railroad and as such hosts the Buxton Homecoming each September. This celebrates the area's black culture and the roots laid by early black settlers in the Buxton area.
