Answer:
The City of Cincinnati is named for the Society of the Cincinnati. This was an association of American and French officers who had served the cause of the rebelling colonies during the US War for independence. They formed the society in part for mutual support, but also to take note of the fact that they had not atttempted to exert poliitical control over the new country through use of the army.
