Grant County is a county in the southwestern part of Wisconsin, a state in the United States. In 2020, about 51,938 people lived here. The main town, called the county seat, is Lancaster. The biggest city in the county is Platteville.

The county got its name from the Grant River. This river was named after a fur trader who lived in the area a long time ago. Grant County is part of a special area called the Platteville Micropolitan Statistical Area. This means it's a smaller city area that is connected to a larger economy.

Grant County is located where three states meet: Wisconsin, Illinois, and Iowa. Many people travel through Grant County. They might be going to Madison, Wisconsin from Iowa, or heading to the Twin Cities or La Crosse, Wisconsin from northern Illinois.

History of Grant County

Early Native American Life

Before Europeans arrived, the area that is now Grant County was mostly empty. It was a border area between the lands of the Kickapoo, Menominee, and Illinois tribes. The only Native Americans who lived here permanently were the Meskwaki people. They had a temporary village in the northeast part of the county in the mid-1700s.

European Explorers and Claims

Between 1520 and 1620, Spain technically ruled this land. However, no Spanish explorers ever visited the area. The first French explorers to reach Grant County were Jacques Marquette and Louis Joliet in 1673. They explored the region but did not build any permanent settlements.

Later, in 1689, Nicholas Perrot claimed the land for the King of France. The first temporary trading post was set up by Pierre Marin in 1725. After the French and Indian War, the British took control. But they also did not settle or manage the area. An explorer from New England, Jonathan Carver, passed through in 1766. He was trying to find the Pacific Ocean.

Becoming Part of the United States

In 1783, the British government agreed that the United States owned the land east of the Mississippi River. This included what is now Grant County. For many years, American and European traders visited the area. They moved around a lot, just like the Native Americans.

Grant County was officially created in 1837. It became part of the Wisconsin Territory. The county was named after an Indian trader, but we don't know his first name or what happened to him.

Ghost Towns and Interesting Stories

Some places in Grant County used to be towns but are now gone. They are called "ghost towns."

Fair Play

Fair Play was a settlement started by a person looking for valuable minerals. Within two years, this person found ore! The settlement was built near Highway 11 and Sandy Hook Road. It was a very lively place, and arguments over money were common. The town got its name from a big fight. One person didn't have a weapon, but the other did. The crowd started yelling "Fair Play! Fair Play!" until the fight stopped. So, the town, which used to be called 'Hard Town', became 'Fair Play'. By 1846, the settlement was abandoned.

Paris

Paris was a small settlement near Dickeyville, close to Highway 151/61. It was built on the Platte River between 1838 and 1843. The person who started the town had a sickness called malaria. He named the place after his home city, Paris, France. He built the county's first bridge across the river. The founder, Detantabaritz, faced money problems. He challenged a person he owed money to a duel with swords, because he used to be a soldier. The other person backed down. Later, the founder sadly took his own life because of his money worries. Today, only a tavern remains there, selling ribs.
