Richland was one of the original three townships of Clinton County. It was erected by the County Commissioners on April 6, 1810 with the boundaries: :all that part of Clinton County east of the old boundary line of
Warren County shall be one township known by the name of Richland. On August 10, 1813, the Commissioners defined the boundaries more precisely: :Beginning at a large hickory at the corner of
Green Township in the line of
Union Township, thence running with the line of Green Township to the southerly corner of the county and at the corner of
Fayette County, thence north with the county line to the northeast corner, then west with the county line to the original line of Warren County, then south with the said original line to the line of Union Township, then with the line of Union Township to the place of beginning. The townships of
Wilson,
Wayne, and Green were created entirely from Richland Township. Parts of
Union and Green were taken from it on August 21, 1813. On July 15, 1817, part was taken to create
Liberty Township. In March 1837, Wayne Township was erected from it and Wilson in August 1850. ==Government==
