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 rafted down the Ohio River in 1788 following the American Revolutionary War. They established the towns of Losantiville (later Cincinnati) and Cleves.
Hamilton County was organized in 1790, as the second county in the Northwest Territory. Its area then included about one-eighth of Ohio, and had about 2,000 inhabitants (not including the remaining Native Americans). The United States persuaded most of the Shawnee and other Indian peoples to remove in the 1820s to locations west of the Mississippi River.
Since then, other counties were created from Hamilton, reducing the county to its present size. Rapid growth occurred during the 1830s and 1840s as the area attracted many German and Irish immigrants, especially after the Great Famine in Ireland and the revolutions in Germany in 1848.
The county lies in a region of gentle hills formed by the slopes of the Ohio River valley and its tributaries. The Great Miami River, the Little Miami River, and the Mill Creek also contribute to this system of hillsides and valleys. No naturally occurring lakes exist, but three major manmade lakes are part of the Great Parks of Hamilton County. The largest lake by far is Winton Woods Lake covering 188 surface acres followed by Miami Whitewater Lake covering 85 surface acres and Sharon Lake covering 36 surface acres.
The county boundaries include the lowest point in Ohio, in Miami Township, where the Ohio River flows out of Ohio and into Indiana. This is the upper pool elevation behind the Markland Dam, 455 feet (139 m) above sea level.

Hamilton County has typically elected Republican candidates in national elections, but has begun to lean Democratic in recent years. In 2008, Barack Obama was the first Democratic presidential candidate to win the county since 1964. The county continued to lean Democratic, voting for Obama again in 2012 and for Democratic candidate Hillary Clinton in 2016. In fact, it was one of the few counties in Ohio to swing toward the Democrats in 2016 even as the state as a whole had swung toward the Republicans.
Due to its tight races and its position in the swing state of Ohio, Hamilton County is regarded as a crucial county to win in presidential elections. In 2012, The Washington Post named Hamilton as one of the seven most important counties in the country for that year's election. Time characterized Hamilton County's political scene as "a battle between conservative suburbs and a Democratic urban center, though Cincinnati is one of the most conservative metro areas in the Midwest."
Public elementary and secondary education is provided by 21 school districts:
In 2016, Cincinnati Public Schools had 35,000 students, 63% of which were African-American.
