Ho-Chunk and Blue Earth, 1855–1863

In 1855, a federal treaty moved the Ho-Chunk (Winnebago) people from their reservation near Long Prairie to a site along the Blue Earth River. The Ho-Chunk farmed the area's rich soil with some success, but drew the hostility of settler-colonist neighbors who wanted the land for themselves. Though they did not participate in the U.S.-Dakota War of 1862, they were exiled from Minnesota during the conflict's aftermath.

Ho-Chunk and Long Prairie, 1846–1855

In 1848 the U.S. government removed the Ho-Chunk (Winnebago) from their reservation in the northeastern part of Iowa to Long Prairie in Minnesota Territory. The Ho-Chunk found the land at Long Prairie a poor match for their needs as farmers. In 1855 they were moved again, this time to a reservation in southern Minnesota.

Hobart, Harriet Duncan (1825–1898)

After New York City schoolteacher Harriet Duncan came to Minnesota in 1868, she became an advocate for temperance and women's suffrage. She was president of the Minnesota Woman's Christian Temperance Union (WCTU) for seventeen years and urged the WCTU to work on behalf of women's rights more broadly.

The 1889 death of inmate Taylor Combs led to a scandal, and then major reforms, at the Rochester State Hospital for the Insane.

Honeywell Round Thermostat

The world's most iconic home thermostat was created in Minneapolis. The Round, designed by engineer Carl Kronmiller and designer Henry Dreyfuss, was introduced in 1953 by the company then known as Minneapolis-Honeywell.

Horsecars of the St. Paul and Minneapolis Street Railway Companies

With the rapid growth of the cities of St. Paul and Minneapolis in the mid-nineteenth century, the need for a reliable form of public transportation became apparent. Horse-drawn streetcars provided the answer and sparked the growth of what would become one of the most extensive streetcar systems in the country.

Hot Ponds

The heated mill pond, or "hot pond," was invented around 1890. This innovation in Minnesota logging made it possible for logging companies to run their sawmills year-round.

Hubbard, Lucius F. (1836–1913)

Young Red Wing newspaper editor Lucius F. Hubbard backed his words with action when he enlisted as a private in the Fifth Minnesota Volunteers during the Civil War. He emerged from the fighting as a general and a war hero, and became wealthy through wheat marketing, milling, and railroads. He was elected governor in 1881.

Hubert H. Humphrey Metrodome, Minneapolis

As enthusiasm for professional sports grew in Minnesota during the mid-twentieth century, Metropolitan Stadium, designed for baseball, became too small and had too few amenities to continue to attract professional teams. By the early 1970s, Minnesota's teams, seeking greater profits, began to demand a bigger and better venue. The Hubert H. Humphrey Metrodome ("The Dome"), a covered, multi-purpose stadium built in downtown Minneapolis, served this purpose for thirty-one years.

Hudson’s Bay Company Trading Post, Georgetown

In 1859, the Hudson’s Bay Company built a trading post and steamboat landing near the meeting point of the Red and Buffalo Rivers in Minnesota. They named the post and the surrounding town Georgetown. The traders left the post during the US–Dakota War of 1862 but returned when the war ended. When the Northern Pacific and other railroad companies built lines through Clay County in the 1870s, the Hudson’s Bay Company abandoned its post at Georgetown.

Humphrey, Hubert H. (1911–1978)

Hubert H. Humphrey, a giant of Minnesota politics, was one of the most influential liberal leaders of the twentieth century. His political rise was meteoric, his impact on public policy historic. His support for the Vietnam War, however, cost him the office he most sought: president of the United States.

Hutterian Brethren, Cottonwood County

South Dakota Hutterite families with roots in the Anabaptist Reformation of the sixteenth-century moved to Cottonwood County in 1994. There, they established the Neuhof Hutterian Brethren Colony and the Elmendorf Hutterian Brethren Colony south of Mountain Lake, Minnesota.

Hydroelectricity in Minneapolis, September 5, 1882

Centralized hydroelectric power came on for the first time in the United States in downtown Minneapolis on September 5, 1882. Minnesota Brush Electric Company produced the power, beating a similar effort in Appleton, Wisconsin, by twenty-five days.

Illustrated Historical Atlas of the State of Minnesota, 1874

When Alfred T. Andreas chose Minnesota as the subject for his new atlas, the state was only fifteen years old. Andreas's publication of An Illustrated Historical Atlas of the State of Minnesota changed the way state atlases were written, illustrated, and distributed. The atlas also put the social and cultural landscape of early Minnesota literally on the map.

Imdieke Brickyard

From 1883-1915, Imdieke Brickyard in Meire Grove produced bricks using traditional European methods. Residents supported this business venture by purchasing materials to create structures that represented their German culture.

Immanuel Baptist Church, Westbrook

The European immigrants who moved into southwestern Minnesota in the mid-1800s brought their religious faiths with them. The founders of Immanuel Baptist Church in Westbrook (Cottonwood County) moved into the first church building erected in the village after the members of that original congregation moved on to other areas, leaving the building vacant.

Immigration to Goodhue County

By 1880, Goodhue County held within its borders four significant Euro-American immigrant enclaves: Minnesota's largest group of Swedish settler-colonists; the second largest assembly of Norwegians; one of the most densely populated German tracts; and an Irish colony at the county's center. The colonizing of Goodhue County serves as a case study of the state's early immigration patterns.

Immigration to the Iron Range, 1880–1930

During the early twentieth century, the population of the Iron Range was among the most ethnically diverse in Minnesota. Tens of thousands of immigrants arrived from Finland, Austria-Hungary, Italy, Sweden, Norway, Canada, England, and over thirty other places of origin. These immigrants mined the ore that made the Iron Range famous and built its communities.

Independent Order of Odd Fellows in Polk County

The Independent Order of Odd Fellows (IOOF) is a service-oriented fraternal organization. Started in England in the 1700s, it spread to the US in the early 1800s and to Minnesota in 1849. In Polk County, though Crookston Lodge No. 73 disbanded in the 1910s, members of Fisher Lodge No. 87 met regularly for over a hundred years.

Indian Mounds Park, St. Paul

The six burial mounds at St. Paul’s Indian Mounds Park are among the oldest human-made structures in Minnesota. Along with mounds in Crow Wing, Itasca, and Beltrami Counties, they are some of the northernmost burial mounds on the Mississippi River. They represent the only ancient American Indian burial mounds still extant inside a major U.S. city.

Indochinese Refugee Resettlement Office, 1975–1986

Between 1975 and 1986, about 750,000 refugees from Vietnam, Cambodia, and Laos resettled in the U.S. They passed through two initiatives: the Refugee Parole Program and the Orderly Departure Program. Voluntary agencies, sponsors, and programs managed by the Indochinese Refugee Resettlement Office offered help. As a result, Minnesota was one of ten states that accepted the largest numbers of refugees.

Industrial Exposition Building, Minneapolis

Built in less than a year, the Industrial Exposition Building in Minneapolis housed the city's first Industrial Exposition in 1886 and the Republican National Convention of 1892. It dominated the Mississippi riverbank east of St. Anthony Falls for decades.

Interstate State Park

The Interstate State Park, located on 295 acres in Taylors Falls, is the second-oldest state park in Minnesota. Created in 1895, its unique topography and geological history draw many visitors to the area. It is the first park in the United States to be located in two states, Minnesota and Wisconsin, with the St. Croix River serving as the border. The two parks are operated separately by the states’ Departments of Natural Resources.

Inyan Ceyaka Otunwe

Inyan Ceyaka Otunwe (“Village at the Barrier of Stone”), also called Little Rapids or simply Inyan Ceyaka, was a summer planting village of the Wahpeton Dakota. Located near present-day Jordan on the Minnesota River, the village was occupied by the Wahpeton during the early 1800s, and likely before. Burial mounds indicate that Paleo-Americans—possible ancestors of the Dakota—lived at the site as early as 100 CE.
