==History==
Jefferson County was organized on July 29, 1797, by proclamation of Governor Arthur St. Clair, six years before Ohio was granted statehood. Its boundaries were originally quite large, including all of northeastern Ohio east of the Cuyahoga River, but it was divided and redrawn several times before assuming its present-day boundaries in 1833, after the formation of neighboring Carroll County.

In 1786, the United States built Fort Steuben to protect the government surveyors mapping the land west of the Ohio River. When the surveyors completed their task a few years later, the fort was abandoned. In the meantime, settlers had built homes around the fort; they named their settlement La Belle. When the county was created in 1797, La Belle was selected as the County seat. The town was subsequently renamed Steubenville, in honor of the abandoned fort.

During the first half of the 19th century, Steubenville was primarily a port town, and the rest of the county consisted of small villages and farms. However, in 1856, Frazier, Kilgore and Company erected a rolling mill (the forerunner of steel mills) and the Steubenville Coal and Mining Company sank a coal shaft, resulting in Jefferson County becoming one of the leading centers of the new Industrial Revolution.

==Politics==
[[File:Steubenville2020.svg|thumb|Results from the 2020 Presidential Election in Steubenville, the county's largest city.]]
Like many [[Appalachia]]n counties, Jefferson County was a strong [[Democratic Party (United States)|Democratic]] county in the 20th century. However, since the turn of the 21st century, it has become much more competitive and even moved towards the [[Republican Party (United States)|Republicans]] during the Democratic years of 2008 and 2012. In 2012, [[Mitt Romney]] became the first Republican candidate to win the county since it voted for [[Richard Nixon|President Nixon]] in the [[1972 United States presidential election in Ohio|1972 presidential election]].
