HistoryEdit

Most of Hamilton County was originally owned and surveyed by John Cleves Symmes, and the region was a part of the Symmes Purchase. The first settlers came down the Ohio River in 1788, and established the towns of Losantiville (later Cincinnati) and Cleves.

In 1790, Hamilton County was organized as the second county in the Northwest Territory. At that time its area included about an eighth of Ohio, and had 2,000 inhabitants (not counting Native Americans). Since then, other counties have been organized and its area reduced to its current size. Rapid growth occurred during the 1830s and 1840s as the area became a magnet for German and Irish immigrants.

During the Civil War, Morgan's Raid (a Confederate cavalry assault) passed through the northern part of the county in 1863.
