Mankato, Minnesota

Mankato (/mænˈkeɪtoʊ/ ^ⓘ man-KAY-toh) is a city in Blue Earth, Nicollet, and Le Sueur counties in the U.S. state of Minnesota. It is the county seat of Blue Earth County. It is the 21st-largest city in Minnesota and fourth-largest outside of the Minneapolis–Saint Paul area with a population of 44,488 at the 2020 census, while the Mankato–North Mankato metropolitan area has an estimated 105,000 residents.

Mankato lies along a large bend of the Minnesota River at its confluence with the Blue Earth River. The city is home to Minnesota State University, the state's second-largest university by enrollment.

Mankato Township was not settled by European Americans until Parsons King Johnson in February 1852, as part of the 19th-century migration of people from the east across the Midwest. New residents organized the city of Mankato on May 11, 1858, the day Minnesota became a state. The city was organized by Johnson, Henry Jackson, Daniel A. Robertson, Justus C. Ramsey, and others. A popular story says that the city was supposed to have been named Mahkato, but a typographical error by a clerk established the name as Mankato. According to Warren Upham, quoting historian Thomas Hughes of Mankato, "The honor of christening the new city was accorded to Col. Robertson. He had taken the name from Nicollet's book, in which the French explorer compared the 'Mahkato' or Blue Earth River, with all its tributaries, to the water nymphs and their uncle in the German legend of Undine...No more appropriate name could be given the new city, than that of the noble river at whose mouth it is located." While it is uncertain that the city was intended to be called Mahkato, the Dakota called the river Makato Osa Watapa ("the river where blue earth is gathered"). The Anglo settlers adapted that as "Blue Earth River". Frederick Webb Hodge, in the Handbook of American Indians North of Mexico, said the town was named after the older of the two like-named chiefs of the Mdewakanton nation of the Santee Dakota, whose village stood on or near the site of the present town.

Ishtakhaba, also known as Chief Sleepy Eye, of the Sisseton band, was said to have directed settlers to this location. He said the site at the confluence of the Minnesota and Blue Earth Rivers was well suited to building and river traffic, and yet safe from flooding.

On December 26, 1862, United States Volunteers of the State of Minnesota carried out the largest mass execution in U.S. history at Mankato after the Dakota War of 1862. Companies of the 7th, 8th, 9th, 10th Minnesota Infantry Regiments, and Minnesota Cavalry oversaw the hanging of 38 men: 35 Santee Sioux and 3 biracial French/native American, for their involvement in the war crimes committed during the uprising. A USV military tribunal reviewed nearly 500 cases, of which 303 received a death sentence, but President Abraham Lincoln requested the court files. He reviewed them, placing the rape cases at the top, and pardoning 265. Episcopal Bishop Henry Benjamin Whipple urged leniency to which Lincoln responded that he had to take a balanced approach. His position and dismissals were unpopular in Minnesota. To commemorate the 50th anniversary of the event a large granite marker was erected that stood at the site until 1971, when the city took it down. Today, a different monument marks the execution site. Across the street are two monuments to the Native Americans in what it called Reconciliation Park. The Blue Earth County Library, Main street and Reconciliation Park cover the immediate vicinity of the execution site.

In 1880, Mankato was Minnesota's fourth-most populous city, with 5,500 residents.

Former Vice President Schuyler Colfax died while traveling through Mankato on January 13, 1885.

According to the United States Census Bureau, the city has a total area of 20.229 square miles (52.39 km²), of which 19.879 square miles (51.49 km²) is land and 0.350 square miles (0.91 km²) is water. The Minnesota, Blue Earth, and Le Sueur rivers all flow through or near the city.
