Native American period

What is now Grant County was largely uninhabited prior to contact with Europeans as it was a border region, it was in between the territory of the Kickapoo, Menominee and Illinois tribes. the only Native American group to have permanent settlement in what is now Grant County were the Meskwaki, sometimes known as the Fox Tribe, who temporarily had a village in what is now the extreme North East of the county during the middle of the 1700s.

Spanish period

Between 1520 and 1620 this area was nominally ruled by Spain, though no Spaniard or anyone who claimed loyalty to Spain had ever come within five hundred miles of the region during this time, and as such, Spanish authority went completely unfelt in what is now Grant County, Wisconsin.

French period

The first Frenchmen to reach what is now Grant County were Jacques Marquette and Louis Joliet who explored the region in the spring of 1673, when they set out from what would later become Green Bay. No permanent settlement was made. In 1680 Louis Hennepin also passed through the region that would later become Grant County, also making no permanent settlement. In 1689 Nicholas Perrot passed through the territory and claimed it for the King of France. The first known settlement by a European came in 1725 when a trading post was established by Pierriere Marin. Later the French would abandon it.

British period

The British technically ruled the region during the period in between the French and Indian War and the American Revolution, though no effort was made to settle or administer the region which would eventually become Grant County. After the French abandoned the trading post established by Marin, the next person of European descent to see what is now Grant County was Captain Jonathan Carver, an English colonial from Connecticut who passed through what is now Grant County in 1776 during an attempt to discover the Pacific Ocean.

United States period

In 1783 the British government acknowledged the jurisdiction of the United States over the land east of the Mississippi River, including what is now Grant County. There were no permanent settlers of either European or Native American descent in what is now Grant County since the French trading post established by Marin was abandoned, both Native Americans of the region and the European and White American fur traders who passed through were nomadic, and left no records. Grant County was created as part of Wisconsin Territory in 1837.[3] It was named after an Indian trader; his first name, origins, and eventual fate are all unknown.[4]


According to the U.S. Census Bureau, the county has a total area of 1,183 square miles (3,060 km2), of which 1,147 square miles (2,970 km2) is land and 36 square miles (93 km2) (3.1%) is water.[5]
