Kansas City, Missouri
Kansas City is the largest city in the U.S. state of Missouri. According to the U.S. Census Bureau, the city had an estimated population of 488,943 in 2017, making it the 37th most-populous city in the United States. It is the central city of the Kansas City metropolitan area, which straddles the Kansas–Missouri state line. Kansas City was founded in the 1830s as a Missouri River port at its confluence with the Kansas River coming in from the west. On June 1, 1850 the town of Kansas was incorporated; shortly after came the establishment of the Kansas Territory. Confusion between the two ensued and the name Kansas City was assigned to distinguish them soon after.

The natural wharf proved to be quite popular but the land surrounding it belonged to Gabriel Prudhomme, a farmer. After Prudhomme was murdered in 1831, his property was auctioned in 1838 to settle the estate. McCoy and 13 others formed a company to buy the property. Their company was called the Town of Kansas after the French description of the area around the town, "chez les Canses" ("home of the Kansa" Indians). In 1853, when the town was officially charted by the state of Missouri, the English pronunciation of the French name was applied to the new "City of Kansas," which later became known as Kansas City.
