Cincinnati, located in southwestern Ohio on the Ohio River, is the third-largest city in the state. Founded in 1788 and incorporated as a city in 1819, it was named after the Society of the Cincinnati, which honored George Washington, whom they likened to the Roman General Cincinnatus. The city saw dramatic growth in the mid 1830s with the development of steamships and the completion of the Ohio and Erie Canal. It soon became a major shipping center, primarily for the pork industry.
