Cincinnati, Ohio's third-most populous city with 309,317 residents in the 2020 census, is the county seat of Hamilton County and serves as the economic and cultural hub of the tri-state metropolitan area, home to over 2.3 million people and ranked as the nation's 30th-largest metro area. Founded in 1788 by Mathias Denman, Colonel Robert Patterson, and Israel Ludlow at the confluence of the Licking and Ohio rivers, the city was renamed from "Losantiville" to Cincinnati in 1790 by Northwest Territory Governor Arthur St. Clair in honor of the Society of the Cincinnati. Steamboat introduction in 1811 and the Miami and Erie Canal (completed to Toledo by 1840) transformed Cincinnati into a major inland port and pork-processing center, propelling it into the top 10 most populous U.S. cities throughout much of the 19th century. The city earned the nickname "Paris of America" in the late 19th century for architectural landmarks including the Music Hall, Cincinnatian Hotel, and Roebling Suspension Bridge, and today hosts the 28th-largest U.S. economy with Fortune 500 companies like Procter & Gamble, Kroger, Fifth Third Bank, and Cintas. Cincinnati's cultural and educational institutions include Xavier University and the University of Cincinnati, while its major sports franchises are the Cincinnati Bengals, Cincinnati Reds, and FC Cincinnati. Hamilton is a city in Butler County, Ohio, located 20 miles north of Cincinnati along the Great Miami River, with a 2020 population of 63,399 making it the second-most populous city in the Cincinnati metropolitan area and the tenth-most populous in Ohio. The city originated as Fort Hamilton, constructed in September-October 1791 by General Arthur St. Clair and named to honor Alexander Hamilton, the first Secretary of the Treasury, serving as a supply station during the Northwest Indian War before being abandoned in 1796 after the Treaty of Greenville. Hamilton was platted as Fairfield in 1794, incorporated in 1810, designated the county seat, and became a city in 1857, gaining national attention when Abraham Lincoln delivered a campaign speech there on September 17, 1859. The Hamilton Hydraulic system, a canal and reservoir network built beginning in 1842 and delivering water power from the Great Miami River starting in January 1845, catalyzed major industrial and population growth from 1840 to 1860 by powering mills and shops throughout the city. Today, Hamilton serves as the county seat of Butler County and is part of the Cincinnati metropolitan region, with most residents served by the Hamilton City School District. Middletown is a city in Butler and Warren counties in southwest Ohio, located 29 miles northeast of Cincinnati and 20 miles southwest of Dayton, with a 2020 population of 50,987. Founded in 1802 by Stephen Vail on land purchased from the 1788 Symmes Purchase, the city was incorporated in 1833 and designated a city in 1886, becoming known for the Miami and Erie Canal (opened 1825) before developing into a major steel town. George Verity's American Rolling Mill Company (ARMCO), established in 1900, transformed Middletown into a steel manufacturing center whose operations continue today under Cleveland-Cliffs ownership. The city, named an All-America City in 1957, also features Hook Field Municipal Airport, a Miami University regional campus, and a Canal Museum opened in 1982 commemorating its transportation heritage. Middletown is part of the Cincinnati metropolitan area and adjoins the Great Miami River across a total area of 26.43 square miles.
