Iowa ( EYE-ə-wə) is a landlocked state in the upper Midwestern region of the United States. It borders the Mississippi River to the east and the Missouri River and Big Sioux River to the west; Wisconsin to the northeast, Illinois to the east and southeast, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north. Iowa is the 26th largest in total area and the 31st most populous of the 50 U.S. states, with a population of 3.19 million. The state's capital, most populous city, and largest metropolitan area fully located within the state is Des Moines.
During the 18th and early 19th centuries, Iowa was a part of French Louisiana and Spanish Louisiana; its state flag is patterned after the flag of France. After the Louisiana Purchase, pioneers laid the foundation for an agriculture-based economy in the heart of the Corn Belt. In the latter half of the 20th century, Iowa's agricultural economy began to transition to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production.
Politically, Iowa is notable for the Iowa Caucuses, an influential event in national politics, as well as its high levels of voter turnout and foundational leadership in civil rights including early adoption or support of black suffrage.
Like many other states, Iowa takes its name from its predecessor, Iowa Territory, whose name in turn is derived from the Iowa River, and ultimately from the ethnonym of the indigenous Ioway people.
The Ioway are a Chiwere-speaking Siouan Nation, who were once part of the Ho-Chunk Confederation that inhabited the area now corresponding to several Midwest states. The Ioway were one of the many Native American nations whose territory comprised the future state of Iowa before the time of European colonization.
Meanwhile, the state nickname, being called the "Hawkeye State" comes from James Fennimore Cooper's second book in his Leatherstocking Tales pentalogy, The Last of the Mohicans: A Narrative of 1757 (published in 1826). Several influential people in Iowa at the time promoted the nickname, including Judge David Rorer and Newspaper editor James G. Edwards, who renamed his newspaper to The Hawk-Eye and Iowa Patriot and eventually to just the Hawk-Eye. The name received official recognition by Iowa Territory Governor Robert Lucas in 1838, when he and several members of his cabinet agreed upon its appropriateness.
When Indigenous peoples of the Americas first arrived in what is now Iowa more than 13,000 years ago, they were hunters and gatherers living in a Pleistocene glacial landscape. By the time European explorers and traders visited Iowa, Native Americans were largely settled farmers with complex economic, social, and political systems. This transformation happened gradually. During the Archaic period (10,500 to 2,800 years ago), Native Americans adapted to local environments and ecosystems, slowly becoming more sedentary as populations increased.
More than 3,000 years ago, during the Late Archaic period, Native Americans in Iowa began utilizing domesticated plants. The subsequent Woodland period saw an increased reliance on agriculture and social complexity, with increased use of mounds, ceramics, and specialized subsistence. During the Late Prehistoric period (beginning about AD 900) increased use of maize and social changes led to social flourishing and nucleated settlements.
The arrival of European trade goods and diseases in the Protohistoric period led to dramatic population shifts and economic and social upheaval, with the arrival of new tribes and early European explorers and traders. There were numerous native American tribes living in Iowa at the time of early European exploration. Tribes which were probably descendants of the prehistoric Oneota include the Dakota, Ho-Chunk, Ioway, and Otoe. Tribes which arrived in Iowa in the late prehistoric or protohistoric periods include the Illiniwek, Meskwaki, Omaha, and Sauk.
Early colonization and trade, 1673–1808
The first known European explorers to document Iowa were Jacques Marquette and Louis Jolliet who traveled the Mississippi River in 1673 documenting several Indigenous villages on the Iowa side. The area of Iowa was claimed for France and remained a French territory until 1763. The French, before their impending defeat in the French and Indian War, transferred ownership to their ally, Spain. Spain practiced very loose control over the Iowa region, granting trading licenses to French and British traders, who established trading posts along the Mississippi and Des Moines Rivers.
Iowa was part of a territory known as La Louisiane or Louisiana, and European traders were interested in lead and furs obtained by Indigenous people. The Sauk and Meskwaki effectively controlled trade on the Mississippi in the late 18th century and early 19th century. Among the early traders on the Mississippi were Julien Dubuque, Robert de la Salle, and Paul Marin. Along the Missouri River at least five French and English trading houses were built before 1808. In 1800, Napoleon Bonaparte took control of Louisiana from Spain in a treaty.
After the 1803 Louisiana Purchase, Congress divided the new land into two parts—the Territory of Orleans and the District of Louisiana, with present-day Iowa falling in the latter. The Indiana Territory, created in 1800, exercised jurisdiction over this portion of the District; William Henry Harrison was its first governor. Much of Iowa was mapped by Zebulon Pike in 1805, but it was not until the construction of Fort Madison in 1808 that the U.S. established tenuous military control over the region.
War of 1812 and unstable U.S. control
Fort Madison was built to control trade and establish U.S. dominance over the Upper Mississippi, but it was poorly designed and disliked by the Sauk and Meskwaki, many of whom allied with the British, who had not abandoned claims to the territory. Fort Madison was defeated by British-supported Indigenous people in 1813 during the War of 1812, and Fort Shelby in Prairie du Chien, Wisconsin, also fell to the British. Black Hawk took part in the siege of Fort Madison. Another small military outpost was established along the Mississippi River in present-day Bellevue. This poorly situated stockade was similarly attacked by hundreds of Indigenous people in 1813, but was successfully defended and later abandoned until settlers returned to the area in the mid-1830s.
After the war, the U.S. re-established control of the region through the construction of Fort Armstrong, Fort Snelling in Minnesota, and Fort Atkinson in Nebraska.
The United States encouraged settlement of the east side of the Mississippi and removal of Indians to the west. A disputed 1804 treaty between Quashquame and William Henry Harrison (then governor of the Indiana Territory) that surrendered much of Illinois to the U.S. enraged many Sauk and led to the 1832 Black Hawk War.
The Sauk and Meskwaki were forced to sell some of their land in the Mississippi Valley to the U.S. in 1832 under the Black Hawk Purchase Treaty and sold their remaining land in Iowa in 1842, most of them moving to a reservation in Kansas. In 1837, some the Potawatomi from Illinois were resettled in Iowa, while many Meskwaki later returned to Iowa and settled near Tama, Iowa; the Meskwaki Settlement remains to this day. In 1856 the Iowa Legislature passed an unprecedented act allowing the Meskwaki to purchase the land. The federal government, in contrast, used treaties to force the Ho-Chunk and the Dakota from Iowa by 1848 and 1858, respectively. Western Iowa around modern Council Bluffs was used as an Indian Reservation for members of the Council of Three Fires.
