Cadiz was founded in 1803 at the junction of westward roads from [[Pittsburgh]] and [[Washington, Pennsylvania]], and named after [[Cádiz, Spain]].

In the early and mid nineteenth century, several local families operated stations and served as conductors in the [[Underground Railroad]], helping runaway slaves escape to Canada.<ref name="villageofcadiz.com"/>

By 1880 population had nearly doubled and the town had three newspapers and three banks.<ref name="ohiohistorycentral.org"/>

Early industry was based on agriculture and processing farm products. In 1889, a brief oil boom began with the shipment of 120 barrels of oil produced in nearby Green Township.<ref>Harrison Historians, "Harrison County, Ohio 1813- 1963", Harrison County, Ohio Celebrates Its 150th Year 1813- 1963, Freeport, OH: The Freeport Press, 1963 pp. 21-22</ref> Coal mining, both underground and surface, became the prominent industry through most of the twentieth century. More recently the development of the Marcellus Shale in the surrounding area has made Cadiz a center for natural gas production. The MarkWest Complex, opened in 2012, processes more than 180 million cubic feet of natural gas per day for shipment via pipeline to Mont Belvieu, Texas.<ref name="villageofcadiz.com"/><ref>{{cite web|url=http://marcellusdrilling.com/2013/04/good-progress-on-markwests-cadiz-oh-processing-plant/|title=Good Progress on MarkWest's Cadiz, OH Processing Plant|date=April 16, 2013|website=Marcellusdrilling.com|access-date=August 14, 2018}}</ref><ref>{{cite web |url=http://www.marcellus-shale.us/Cadiz-Ohio_complex.htm |title=Cadiz Ohio Complex |access-date=June 8, 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150624003814/http://www.marcellus-shale.us/Cadiz-Ohio_complex.htm |archive-date=June 24, 2015}}</ref>
