Cincinnati

City and port in southwestern Ohio, on the northern bank of the Ohio River; seat of Hamilton County; population (2000 est) 331,300. The city is an important inland port on the Ohio–Mississippi system, and a major manufacturing centre; its chief industries include aircraft and car machinery, clothing, furniture making, wine, chemicals, and meatpacking. Founded in 1788 as Losantiville, Cincinnati was incorporated as a city in 1819. It attracted large numbers of European immigrants, particularly Germans, during the 19th century.

History
The city was called Cincinnati from 1790 after a society of revolutionary army veterans (formed 1783). In the 1850s the leading industry here was meat packing, which led to Cincinnati being nicknamed ‘Porkopolis’. Located on the Mason–Dixon Line, Cincinnati was a focal point for anti-slavery activity and it provided shelter for many escaped slaves before 1862.
