Harlan Township, Warren County

How Harlan Township, Warren County began

Harlan Township was carved out of the southern part of Salem Township by the Ohio General Assembly on March 16, 1860, and named for Aaron Harlan of Xenia, a Warren County native who had represented the district in Congress and earlier served in both houses of the Ohio legislature. It sits in the southeast corner of Warren County and has never held a large town of its own: its small places — Edwardsville, Rossburg, Butlerville, Pleasant Plain and Level — grew up around a turnpike, a tannery and a railroad rather than a county seat. Its largest community, Blanchester, was platted in 1832 on the Clinton County side of the line the Blancett brothers' town would later straddle, and only the township's edge of that village lies in Warren County. The township remains rural and agricultural today, drained by tributaries of the East Fork of the Little Miami River.

Incorporated 1860-03-16, by Ohio General Assembly, dividing Salem Township.

Where the name comes from

The township is named for Aaron Harlan (September 8, 1802 – January 8, 1868), who was born in Warren County, admitted to the bar in 1825, and practiced law in Xenia. He served in the Ohio House of Representatives (1832-1833) and Ohio Senate (1838-1840, 1849-1850), was a presidential elector in 1844, and represented Ohio's 7th district in the U.S. House from 1853 to 1859 as a Whig, then Anti-Nebraska, then Republican. The township was named for him when the General Assembly created it in 1860. He later moved to San Francisco, where he died in 1868.

Before the town

No village, mound, or treaty line specific to the land that became Harlan Township is recorded in the sources checked; the 1882 Beers county history states plainly that no tribe of Indians permanently lived within the bounds of what became Warren County, though extensive ancient earthworks showed the region had been occupied by mound-building peoples long before. The nearest historic-era Native settlement the same history names was the Shawnee town of Old Chillicothe (Chalahgawtha), on the Little Miami near present Oldtown in Greene County — outside the township but within a day's travel, occupied 1774-1780 and destroyed by George Rogers Clark's militia in 1780. Through the 1700s the Miami confederacy claimed most of western Ohio, including this ground, before the Shawnee moved onto the upper Miami rivers around 1765; both nations, along with the Wyandot, Lenape (Delaware) and others, ceded their claim to lands including the future Warren County at the 1795 Treaty of Greenville after General Anthony Wayne's victory at Fallen Timbers. The Adena and Hopewell mound-building cultures (about 800 BC to AD 500) are well attested elsewhere in the county, notably at Fort Ancient in Washington Township and the Stubbs Earthworks in Hamilton Township, but no mound or earthwork specific to Harlan Township turned up in the sources searched.

Nations recorded here: Shawnee, Miami, Wyandot, Lenape (Delaware), Adena culture, Hopewell culture.

3. 1824 — Edward Thomas laid out Edwardsville in March 1824 along the old State road of 1822, the first town regularly platted within what is now Harlan Township; it was never built up beyond its recorded plat of 42 lots.

5. 1833 — A post office was established at Rossburg under postmaster Jefferson Stevens.
6. 1834 — A post office called Level, later a station on the Marietta and Cincinnati Railroad, opened in southern Harlan Township; it operated until 1905.

Stories

A village split by a county line

Blanchester was never platted with Harlan Township in mind at all. In March 1832, brothers Joseph and John Blancett recorded a plat of twenty-four lots in the southwestern corner of Marion Township, Clinton County, on land well south of the line that would one day separate Clinton from Warren. They named the streets Broadway and Main and named the town for themselves, and it grew steadily through additions in 1832, 1834 and a resurvey in 1835 before incorporating in 1865. As the village spread, its edge crossed the county line, and today Blanchester is legally 'a village in Clinton and Warren counties' — one of only a handful of Ohio villages split between two counties, run as a single municipal government but reported in two different courthouses. The available sources do not say precisely how much of the built-up village, if any, sits on the Warren County side today, only that the Harlan Township portion is real; that gap is noted below rather than guessed at.

The tannery that never became a town

Before Harlan Township existed, before Blanchester's plat was recorded, a settlement called Rossburg was already doing business on the old State road near the Salem line. Enoch A. Ross opened the township's first tannery there about 1820, and by the mid-1820s the crossroads had a Methodist Episcopal church, a store run by Daniel Holmes and his brother, and, from 1833, its own post office under Jefferson Stevens. Rossburg was never formally platted as a town — it simply grew around the tannery — and it never got the boost of a turnpike or a railroad the way Butlerville and Level later did. The Beers county history records its decline in a single blunt sentence: other towns, with better advantages, superseded it. A few miles away, Edwardsville tells the mirror-image story — Edward Thomas laid out 42 lots along the 1822 State road in March 1824, the first town regularly platted in what became Harlan Township, but the lots never sold and nothing was ever built beyond the recorded plat.

Naming a township for the sitting congressman

Harlan Township is not an old name inherited from a pioneer settler or a river crossing; it was assigned in 1860 by the Ohio General Assembly, to honor a man who had served in both of its houses. Aaron Harlan was born in Warren County in 1802, read law and set up practice in Xenia, and worked his way from the Ohio House and Senate up to the U.S. House of Representatives, where he sat for three terms, 1853 to 1859, shifting from Whig to Anti-Nebraska to Republican as the party system broke apart around him. When the legislature split the southern half off from Salem Township in March 1860, its members named the new subdivision for their former colleague. Harlan never lived to see much of the Ohio he'd represented change further than the Civil War: he moved his practice west and died in San Francisco in January 1868.
