Grant County was formed in 1831 by migrants from Kentucky and Virginia. It was named for Captains Samuel and Moses Grant of Kentucky, who were killed fighting Indians north of the Ohio River.  Their home county was also named in memory of them: Grant County, Kentucky.
In 1831, Martin Boots and David Branson each donated 30 acres of land to begin a settlement called Marion. This land was on the north side of a fast-flowing and scenic river the Miami Indians called Mississinewa. Marion was designated as the County Seat. 
As the county was developed for agriculture, the county seat became a center of trade and business, as well as government and the court system. On August 7, 1930, a white mob of an estimated 5,000 people took three African-American men, Thomas Shipp and Abram Smith, both 19, and James Cameron, 16, from the county jail. They were suspects in a robbery/murder and rape. The first two young men were lynched and hanged from trees in the courthouse square. Cameron was spared and later became a civil rights activist. This was the last lynching in Indiana. 
In 1982, Stephen Johnson was elected as Grant County's first full-time prosecutor. He served for five consecutive terms, from 1983 through 2002. 
According to the 2010 census, the county has a total area of 414.90 square miles (1,074.6 km2), of which 414.07 square miles (1,072.4 km2) (or 99.80%) is land and 0.82 square miles (2.1 km2) (or 0.20%) is water.

County Council: The county council is the legislative branch of the county government and controls all the 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.  
Board of Commissioners: The executive body of the county is made of a board of commissioners. The commissioners are elected county-wide, in staggered terms, and each serves a four-year term.

The commissioners are charged with executing the acts legislated by the council, collecting revenue, and managing the day-to-day functions of the county government.  
Court: 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.
