Losantiville grew over the subsequent years as more settlers arrived. In 1790, the town was named the county seat of Hamilton County by Arthur St. Clair, the Northwestern Territory governor. St. Clair renamed Losantiville, bestowing upon the growing settlement the name of Cincinnati.
Cincinnati got its name from the 5th-century BC Roman soldier and hero, Lucius Quinctius Cincinnatus. After leading the republic’s army to victory over invaders, he denied rewards, returning to a farm where he lived out the remainder of his days instead. For many people, and especially Revolutionary War-era Patriots, Cincinnatus embodied self-sacrifice, patriotic loyalty, integrity, and civic virtue. In particular, his history represented for new Americans the promise of democracy and the possibility of overcoming tyranny.
Cincinnatus’ bravery inspired both Governor St. Clair and the founders of the Society of the Cincinnati, also named after the same Roman “people’s hero.” The Society of the Cincinnati, to which the name of the city of Cincinnati was also a nod, was founded by Continental Army officers in Newburgh, New York, in 1783. The Society still exists today as a fraternal philanthropic and patriotic organization dedicated to what its members describe as the values and memory of the American Revolution.
In 1790, Governor St. Clair was the President of the State Society of the Cincinnati of Pennsylvania, explaining his deep connection to the name and its origins. Many members of the Society had settled throughout the territory he governed, making Cincinnati a particularly suitable name for the growing region.
Cincinnati was subsequently incorporated as a town in 1802 and officially recognized as a city in 1819. It would eventually become, for a time, the most densely populated city in the United States and a major center of industry and commerce.
