After the American Revolutionary War was settled, the fledgling nation created the Northwest Territory, tentatively divided into two counties. The area that would become the state of Indiana in 1816 was included in the original Knox County. As the area became more settled, Knox was partitioned into smaller counties, the last of which was the present-day Daviess, authorized on 2 February 1818. The boundaries of Daviess were reduced on 21 December 1818 by the formation of Owen County, and on 17 January 1820 by the formation of Martin County. It has retained its present boundary since 1820. Daviess County was named for Major Joseph Hamilton Daveiss, U.S. District Attorney for Kentucky, killed at the Battle of Tippecanoe in 1811. The earliest settlements were along the White River, which allowed crops and timber to be transported to distant markets. The northeast part of the county was heavily forested, and timber industry flourished in the first half of the nineteenth century. Daviess County shares its namesake with another nearby Daviess County of Kentucky. Both Counties are in the Illinois-Indiana-Kentucky Tri-State Area.

The county government is a constitutional body, and is granted specific powers by the Constitution of Indiana, and by the Indiana Code. The county council is the legislative branch of the county government and controls spending and revenue collection in the county. Representatives are elected from county districts. The council members serve four-year terms. They are responsible for setting salaries, the annual budget, and special spending. The council also has limited authority to impose local taxes, in the form of an income and property tax that is subject to state level approval, excise taxes, and service taxes. A board of commissioners constitutes the county's executive body. Commissioners are elected county-wide, in staggered four-year terms. One commissioner serves as president. The board executes the council's legislative acts, collects revenue, and manages the county's government functions. The county maintains a small claims court that can handle some civil cases. The judge on the court is elected to a term of four years and must be a member of the Indiana Bar Association. The judge is assisted by a constable who is also elected to a four-year term. In some cases, court decisions can be appealed to the state level circuit court.
