Blue Earth County is a county located in the State of Minnesota. As of the 2010 census, the population was 64,013.[2] Its county seat is Mankato.[3] The county is named for the Blue Earth River and for the deposits of blue-green clay once evident along the banks of the Blue Earth River.

Blue Earth County is part of the Mankato–North Mankato, MN Metropolitan Statistical Area.

History[edit]

The area of Blue Earth County was once known as the "Big Woods" and was occupied by the Dakota Indians. It was started by a French explorer, Pierre-Charles Le Sueur. He was one of the first White people in this area, arriving at the point where the Minnesota and Blue Earth rivers meet. There, he made an unsuccessful attempt to mine copper from the blue earth found in the area. The area remained under French control until 1803, but soon after was passed to the United States by the Louisiana Purchase. When Minnesota became a territory in 1849, the territorial government became interested in having the river valley for settlement. In 1850 the first steamboat trip, starting in St. Paul, traveled on the Minnesota River and came to the Blue Earth River. The first White settlers, P.K. Johnson and Henry Jackson came off the boat and settled in present day Mankato. The ratification of the Mendota and Traverse des Sioux Treaties in 1851 effectively forced the Dakota to leave the area for nearby reservations.

The county of Blue Earth was finally created after a division of the Minnesota Territory on March 5, 1853 from portions of Dakota County and free territory. It was named after the Blue Earth River. The first government officials were appointed by Alexander Ramsey, who was the territorial governor at that time. That October the first election was held for government officials with a total of 22 ballots being taken.

Unfulfilled treaty promises and starvation on the Indians reservation led to the Dakota War of 1862, which resulted in Dakota defeat and the largest mass execution in US history in Mankato. In 1868 the railroads arrived. They helped with the growth and development of many areas, including Blue Earth. The railroads allowed many different White ethnic immigrants and Yankee settlers into the area. Blue Earth has grown into a very good county for agriculture, industry, business, education, and culture, and still continues to grow today.

Native vegetation based on NRCS soils information[5]

There are many "closed forest savannas" that some call the big woods in the northeastern part of the county. The rivers that flow out of the northeastern part are surrounded by these big woods. Most of the county is grassland prairie but scattered parts of it are wet prairie. Some spots that surround the rivers are oak openings and barren brushland.
