History
Indian presence
What is now Grant County was largely uninhabited prior to contact with Europeans, as it was a border region between the territories of the Kickapoo, Menominee, and Illinois tribes. The only Native Americans to have a permanent settlement in the area were the Fox tribe, who had a temporary village in what is now the extreme northeast of the county during the mid-1700s.
Colonial period
Between 1520 and 1620 this area was nominally ruled by Spain, although the lack of explorers left the region completely untouched by Spanish authority. 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, after setting 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 settlement was a temporary trading post that Pierre Marin founded in 1725.
The British technically ruled the region during the period between the French and Indian War and the American Revolution, though no effort was made to settle or administer the region. After the abandonment of Marin’s trading post, the region went unvisited until the expedition of Jonathan Carver, a Connecticut Yankee who passed through what is now Grant County in 1766 during an attempt to discover the Pacific Ocean.
American 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. American and European traders visiting the region over the next decades were yet as nomadic as the Indians, and no records survive. Grant County was created as part of Wisconsin Territory in 1837. It was named after an Indian trader; his first name, origins, and eventual fate are all unknown.
