Iowa (, Lakota: Ayúȟwa) is a state in the upper Midwestern region of the United States, bordered by the Mississippi River to the east and the Missouri River and Big Sioux River to the west. It is bordered by six states: 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.
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, people 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 transitioned to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production.
Iowa is the 26th most extensive in total area and the 31st most populous of the 50 U.S. states, with a population of 3,190,369, according to the 2020 census. The state's capital, most populous city, and largest metropolitan area fully located within the state is Des Moines. A portion of the larger Omaha, Nebraska, metropolitan area extends into three counties of southwest Iowa. Iowa has been listed as one of the safest U.S. states to live in.
Etymology
Iowa derives its name from the Ioway people, 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.
History
Prehistory
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.
