Map of North Dakota

North Dakota ( də-KOH-tə) is a landlocked U.S. state in the Upper Midwest, named after the indigenous Dakota and Sioux peoples. It is bordered by the Canadian provinces of Saskatchewan and Manitoba to the north and by the U.S. states of Minnesota to the east, South Dakota to the south, and Montana to the west. North Dakota is part of the Great Plains region, characterized by broad prairies, steppe, temperate savanna, badlands, and farmland. North Dakota is the 19th-largest state by area, but with a population of just under 800,000, the fourth-least populous and fourth-least densely populated. The state capital is Bismarck and the most populous city is Fargo, which accounts for nearly a fifth of the state's population; both cities are among the fastest-growing in the U.S., although half of North Dakotans live in rural areas.

The area of North Dakota was inhabited for thousands of years by Native American tribes, including the Mandan, Hidatsa, and Arikara along the Missouri River; the Ojibwe and Cree in the northeast; and several Sioux groups (the Nakota, Dakota, and Lakota) in the rest of the state. European explorers and traders first arrived in the early 18th century, mostly in pursuit of furs.

The United States acquired the region in the early 19th century, gradually settling it amid growing resistance by increasingly displaced natives. The Dakota Territory, established in 1861, became central to American pioneers, with the Homestead Act of 1862 precipitating significant population growth and development. The traditional fur trade declined in favor of farming, particularly of wheat. The Dakota Boom of 1878 to 1886 saw giant farms stretched across the rolling prairies, with the territory becoming a regional economic power. The Northern Pacific and Great Northern railway companies competed for access to lucrative grain centers; farmers banded together in political and socioeconomic alliances that were central to the Midwest's broader Populist Movement.
