Short answers, pulled from the story.
Cincinnati was founded in 1788 when Mathias Denman, Colonel Robert Patterson, and Israel Ludlow landed at the northern bank of the Ohio River opposite the mouth of the Licking River and established a settlement. The settlement was originally named Losantiville before Governor Arthur St. Clair renamed it Cincinnati on the 4th of January 1790.
Cincinnati was named in honor of the Society of the Cincinnati, a fraternal organization of Continental Army officers from the Revolutionary War. Governor Arthur St. Clair, who was president of the Society at the time, changed the name from Losantiville in 1790. The Society itself was named for Lucius Quinctius Cincinnatus, a Roman dictator who saved Rome from a crisis and then returned to farming rather than retain power.
Cincinnati was a major crossing point for the Underground Railroad because of its location on the Ohio River, which marked the border between the free state of Ohio and the slave state of Kentucky. Levi Coffin made the Cincinnati area the center of his anti-slavery efforts from 1847, and the city had numerous Underground Railroad stations. The National Underground Railroad Freedom Center opened in 2004 along the riverfront to commemorate this history.
Cincinnati earned the nickname Porkopolis because of its prominence as a center for pork processing throughout the 19th century. The city became a regional hub for exporting pork products via the Ohio River. In 1988, the city embraced the nickname when it commissioned British artist Andrew Leicester to create a sculpture for Bicentennial Commons featuring winged pigs atop steamboat smokestacks, which later inspired the city's Flying Pig Marathon.
Cincinnati is home to multiple Fortune 500 companies including Kroger, Procter and Gamble, Western and Southern, Fifth Third Bank, and American Financial Group. GE Aerospace is headquartered in the nearby suburb of Evendale. Kroger is the largest employer in the city with more than 20,000 local workers. The region's economy ranked 28th largest in the United States with a gross domestic product of $127 billion in 2015.
The Cincinnati Subway was approved by voters in 1917 with a $6 million budget for a 16-mile loop through the city and suburbs. World War I delayed construction until 1920, and inflation drove costs past $13 million. Mayor Murray Seasongood halted the project on affordability grounds, and the Wall Street Crash of 1929 ended construction entirely. The tunnels remain unfinished and unused beneath the city today.
