History of Trempealeau County

Early Times and Native Americans

Long ago, this area was covered with light forests and brush. Native Americans lived here. They would sometimes burn parts of the woodlands. This helped berries grow better. By 1837, most Native Americans had left the area. The land was given up by the Dakota people in a treaty signed that year.

French Explorers and the County's Name

French fur traders were the first Europeans to explore this land. They traveled by river. When they reached where the Trempealeau River meets the Mississippi River, they saw a bluff. It was a tall hill surrounded by water. They called it La Montagne qui trempe à l’eau. This means "mountain steeped in water."

Today, this bluff is known as Trempealeau Mountain. The name was later shortened to Trempealeau. The county was created in 1854 and officially started in 1855. It was named after the river.

Immigration and New Communities

In the 1800s and 1900s, many Norwegian people came to Trempealeau County. They were looking for cheap land, a better life, and more chances. Many people in the county today are still of Norwegian background. They celebrate their heritage by making traditional Norwegian foods. They also take part in Norwegian Constitution Day events.

In the late 1850s, Polish settlers from a region called Upper Silesia also came. They wanted to escape problems in their homeland. They built churches, schools, and new communities. This area became the second-largest Polish settlement in the United States. These settlements were mainly around Independence, Arcadia, Whitehall, and Pine Creek. Many people in Trempealeau County today are still of Silesian Polish descent.

More recently, in the early 2000s, many Hispanic and Latino people moved to the county. Trempealeau County continues to be a place where different cultures come together.
