 In 1790, Arthur St. Clair, the governor of the Northwest Territory, changed the name of the settlement to "Cincinnati" in honor of the Society of the Cincinnati, made up of Revolutionary War veterans, of which he was a member; which was in turn named for Lucius Quinctius Cincinnatus, a dictator in the early Roman Republic who saved Rome from a crisis, and then retired to farming because he did not want to remain in power.The introduction of steamboats on the Ohio River in 1811 opened up the city's trade to more rapid shipping, and the city established commercial ties with St. Louis, Missouri and New Orleans downriver.Cincinnati was incorporated as a city on March 1, 1819.
