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.
Kansas City Royals
The name Royals pays homage to the American Royal, a livestock show, horse show, rodeo, and championship barbeque competition held annually in Kansas City since 1899 as well as the identical names of two former negro league baseball teams that played in the first half of the 20th century (one a semi-pro team based in Kansas City in the 1910s and 1920s that toured the Midwest and a California Winter League team based in Los Angeles in the 1940s that was managed by Chet Brewer and included Satchel Paige and Jackie Robinson on its roster). The Los Angeles team had personnel connections to the Monarchs but could not use the Monarchs name. The name also fits into something of a theme for other professional sports franchises in the city, including the Kansas City Chiefs of the NFL, the former Kansas City Kings of the NBA, and the former Kansas City Monarchs of the Negro National League.
