History

The southern portion 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), North Bend, and Columbia.

Hamilton County was organized in 1790 by order of Arthur St. Clair, governor of the Northwest Territory, as the second county in the Northwest Territory. Cincinnati was named as the seat. Residents named the county in honor of Alexander Hamilton, who was the first Secretary of the Treasury of the United States and a founder of the Federalist Party. Its original boundaries were those defined for the Symmes purchase contract in 1788:[5] the Ohio River in the South, Great Miami River to the west, the Lesser Miami River to the east, and the Cayuhoga River to the North. Its area then included about one-eighth of Ohio, and had about 2,000 inhabitants (not including the remaining Native Americans). The county was greatly expanded in 1792 to include what is today the lower peninsula of Michigan. Since 1796, other counties were created from Hamilton, reducing the county to its present size.

The county was the location of much of the Northwest Indian War both before and after its organization.

The United States forcibly removed most of the Shawnee and other Indian peoples to move to locations west of the Mississippi River in the 1820s. 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.

During the Civil War, Morgan's Raid (a Confederate cavalry campaign from Kentucky) passed through the northern part of the county during the summer of 1863.

Geography
Château Laroche in Symmes Township lies in the Little Miami Valley.

According to the U.S. Census Bureau, the county has a total area of 413 square miles (1,070 km2), of which 406 square miles (1,050 km2) is land and 6.7 square miles (17 km2) (1.6%) is water.[6]

Geographic features

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.[7] 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.[8]

The highest land elevation in Hamilton County is the Rumpke Sanitary Landfill at 1,045 feet (319 m) above sea level in Colerain Township.

Population

The County’s highest population was recorded in the 1970 U.S. Census. Since then, the County has lost population at an average rate of three percent per decade. Although Hamilton County is experiencing a decline in birth rates and has higher death rates in older age groups (cohorts), out-migration of residents is the key factor in population loss. In the last decade, this population loss has been reversed, and it is estimated that both Hamilton County and the City of Cincinnati have grown their populations. [19] The Cincinnati Metropolitan Statistical Area, over the last three decades has seen a 19 percent increase in population. Much of the region’s growth has been through movement of Cincinnati and Hamilton County residents into neighboring counties.[19]

Government

As of 2020, the members of the Hamilton Board of County Commissioners are Denise Driehaus, Stephanie Summerow Dumas, and Victoria Parks.[20][21]

Since 1963, the Board has employed an administrator to run the day-to-day operations of the county; the current administrator is Jeffrey Aluotto. Other elected officers include Dusty Rhodes (Auditor), Joe Deters (Prosecutor), Jim Neil (Sheriff), Theodore B. Hubbard, (Engineer), Norbert Nadel (Recorder), Robert A. Goering (Treasurer), and Lakshmi Sammarco (Coroner).

As of 2018, the elected Common Pleas Court include: Judge Charles J. Kubicki, Jr., Judge Lisa Allen, Judge Kim Wilson Burke, Judge Thomas O. Beridon, Judge Elizabeth A. Callan, Judge Ethna M.

Politics

Hamilton County historically elected Republican candidates in national elections, but has trended 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. In the 2018 midterm elections, with the election of Democrat Stephanie Summerow Dumas, the Hamilton County Board of Commissioners was completely under Democratic control for the first time ever.[23] They had previously regained a 2/3rds majority control of the Board of Commissioners in 2016 with the election of Denise Driehaus. In 2019, longtime Democratic Commissioner Todd Portune announced his resignation from the Board due to health problems. Portune's Chief of Staff, Victoria Parks, was appointed to serve the remainder of his term (through the November 2020 general election). With Parks' appointment, the Board of Commissioners became for the first time all-female and majority black.[20]

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.[24] 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."[25]
