Iowa(/ˈaɪ.əwə/EYE-ə-wə)is a doubly landlockedstatein the upperMidwesternregion of theUnited States.It borders theMississippi Riverto the east and theMissouri RiverandBig Sioux Riverto the west;Wisconsinto the northeast,Illinoisto the east and southeast,Missourito the south,Nebraskato the west,South Dakotato the northwest, andMinnesotato the north.

Iowa is the26th largestin total area and the31st most populousof the50 U.S. states,with a population of 3,190,369,according to the2020 census.The state'scapital,most populous city,and largestmetropolitan areafully located within the state isDes Moines.A portion of the largerOmaha, Nebraska, metropolitan areaextends into three counties of southwest Iowa.Iowa has been listed as one of the safest U.S. states in which to live.

During the 18th and early 19th centuries, Iowa was a part ofFrench LouisianaandSpanish Louisiana;itsstate flagis patterned after theflag of France.After theLouisiana Purchase,people laid the foundation for an agriculture-based economy in the heart of theCorn 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,andgreen energyproduction.As of 2018, 22.6 million hogs outnumbered Iowans by more than 7 to 1 in 8,000 facilities large enough to require manure management plans.

Etymology

Likemany other states,Iowa takes its name from its predecessor,Iowa Territory,whose name in turn is derived from theIowa River,and ultimately from theethnonymof the indigenousIoway people. The Ioway are aChiwere-speakingSiouan Nation,who were once part of theHo-ChunkConfederation that inhabited the area now corresponding to severalMidweststates. The Ioway were one of the manyNative Americannations whose territory comprised the future state of Iowa before the time of European colonization.

Prehistory

Main articles:Iowa archaeologyandAmerican Indians of Iowa

Excavation of the 3,800-year-oldEdgewater Park Site

WhenIndigenous peoples of the Americasfirst arrived in what is now Iowa more than 13,000 years ago, they were hunters and gatherers living in aPleistoceneglacial 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 theArchaic 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 theLate Archaic period,Native Americans in Iowa began utilizing domesticated plants. The subsequentWoodland periodsaw 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 prehistoricOneotainclude theDakota,Ho-Chunk,Ioway,andOtoe.Tribes which arrived in Iowa in the late prehistoric or protohistoric periods include theIlliniwek,Meskwaki,Omaha,andSauk.

Iowa in 1718 with the modern state area highlighted

The first known European explorers to document Iowa wereJacques MarquetteandLouis Jollietwho traveled theMississippi Riverin 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 theFrench 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 theMississippiandDes Moines Rivers.

Iowa was part of a territory known asLa LouisianeorLouisiana,and European traders were interested in lead and furs obtained by Indigenous people. TheSaukandMeskwakieffectively controlled trade on the Mississippi in the late 18th century and early 19th century. Among the early traders on the Mississippi wereJulien Dubuque,Robert de la Salle,andPaul Marin.Along theMissouri Riverat least five French and English trading houses were built before 1808.In 1800,Napoleon Bonapartetook control of Louisiana from Spain in atreaty.

After the 1803Louisiana Purchase,Congress divided the Louisiana Purchase into two parts—the Territory of Orleans and the District of Louisiana, with present-day Iowa falling in the latter. TheIndiana Territory,created in 1800, exercised jurisdiction over this portion of the District;William Henry Harrisonwas its first governor. Much of Iowa was mapped byZebulon Pikein 1805,but it was not until the construction ofFort Madisonin 1808 that the U.S. established tenuous military control over the region.

War of 1812 and unstable U.S. control

Main article:Missouri Territory

Fort Madisonwas 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 Madisonwas defeated by British-supported Indigenous people in 1813 during theWar of 1812,andFort ShelbyinPrairie du Chien, Wisconsin,also fell to the British.Black Hawktook part in the siege of Fort Madison.Another small military outpost was established along the Mississippi River in present-dayBellevue.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 ofFort Armstrong,Fort SnellinginMinnesota,andFort AtkinsoninNebraska.

Indian removal, 1814–1832

See also:Indian removal

The United States encouraged settlement of the east side of the Mississippi and removal of Indians to the west.A disputed1804 treatybetweenQuashquameandWilliam Henry Harrison(then governor of theIndiana Territory) that surrendered much ofIllinoisto the U.S. enraged many Sauk and led to the 1832Black Hawk War.

TheSaukandMeskwakisold their land in theMississippi Valleyduring 1832 in theBlack Hawk Purchaseand sold their remaining land in Iowa in 1842, most of them moving to a reservation in Kansas.Many Meskwaki later returned to Iowa and settled nearTama, Iowa;theMeskwaki Settlementremains to this day. In 1856 the Iowa Legislature passed an unprecedented act allowing the Meskawki to purchase the land.However, in contrast to the unprecedented act of the Iowa Legislature, the United States Federal Government, through the use of Treaties, forced theHo-Chunkfrom Iowa in 1848,and forced theDakotafrom Iowa by 1858.Western Iowa around modernCouncil Bluffswas used as an Indian Reservation for members of theCouncil of Three Fires.

Bellevuealong the Mississippi, 1848

The first American settlers officially moved to Iowa in June 1833.Primarily, they were families fromOhio,Pennsylvania,New York,Indiana,Kentucky,andVirginiawho settled along the western banks of theMississippi River,founding the modern day cities ofDubuqueandBellevue.On July 4, 1838, theU.S. Congressestablished theTerritory of Iowa.PresidentMartin Van BurenappointedRobert Lucasgovernor of the territory, which at the time had 22 counties and a population of 23,242.

Almost immediately after achieving territorial status, a clamor arose for statehood. On December 28, 1846, Iowa became the 29th state in the Union when PresidentJames K. Polksigned Iowa's admission bill into law. Once admitted to the Union, the state's boundary issues resolved, and most of its land purchased from Natives, Iowa set its direction to development and organized campaigns for settlers and investors, boasting the young frontier state's rich farmlands, fine citizens, free and open society, and good government.

Iowa has a long tradition of state and county fairs. The first and secondIowa State Fairswere held in the more developed eastern part of the state atFairfield.The first fair was held October 25–27, 1854, at a cost of around $323. Thereafter, the fair moved to locations closer to the center of the state and in 1886 found a permanent home in Des Moines. The State Fair has been held annually since then, except for a few exceptions: 1898 due to theSpanish–American Warand theWorld's Fairbeing held in nearbyOmaha, Nebraska;from 1942 to 1945, due toWorld War II,as the fairgrounds were being used as an army supply depot; and in 2020 due to theCOVID-19 pandemic in the United States.

Civil War, 1861–1865

Main article:Iowa in the American Civil War

Iowa supported the Union during theCivil War,voting heavily forAbraham Lincoln,though there was an antiwar "Copperhead"movement in the state, caused partially by a drop in crop prices caused by the war.There were no battles in the state, although theBattle of Athens,Missouri, 1861, was fought just across the Des Moines River fromCroton, Iowa,and shots from the battle landed in Iowa. Iowa sent large supplies of food to the armies and the eastern cities.

Much of Iowa's support for the Union can be attributed toSamuel J. Kirkwood,its first wartime governor. Of a total population of 675,000, about 116,000 men were subjected to military duty. Iowa contributed proportionately more soldiers to Civil War military service than did any other state, north or south, sending more than 75,000 volunteers to the armed forces, over one-sixth of whom were killed before theConfederatessurrendered atAppomattox.

Most fought in the great campaigns in theMississippi Valleyand in theSouth.Iowa troops fought at Wilson's Creek inMissouri,Pea RidgeinArkansas,Forts Henry and Donelson, Shiloh, Chattanooga, Chickamauga, Missionary Ridge, and Rossville Gap as well as Vicksburg, Iuka, and Corinth. They served with the Army of the Potomac inVirginiaand fought under Union GeneralPhilip Sheridanin theShenandoah Valley.Many died and were buried at Andersonville. They marched on GeneralNathaniel Banks' ill-starred expedition to the Red River. Twenty-sevenIowanshave been awarded theMedal of Honor,the highest military decoration awarded by the United States government, which was first awarded in the Civil War.

Iowa had several brigadier generals and four major generals—Grenville Mellen Dodge,Samuel R. Curtis,Francis J. Herron,andFrederick Steele—and saw many of its generals go on to state and national prominence following the war.

Agricultural expansion, 1865–1930

Following the Civil War, Iowa's population continued to grow dramatically, from 674,913 people in 1860to 1,624,615 in 1880.The American Civil War briefly brought higher profits.

In 1917, the United States entered World War I and farmers as well as all Iowans experienced a wartime economy. For farmers, the change was significant. Since the beginning of the war in 1914, Iowa farmers had experienced economic prosperity, which lasted until the end of the war.In the economic sector, Iowa also has undergone considerable change. Beginning with the first industries developed in the 1830s,which were mainly for processing materials grown in the area,Iowa has experienced a gradual increase in the number of business and manufacturing operations.

Depression, World War II and manufacturing, 1930–1985

The transition from an agricultural economy to a mixed economy happened slowly. TheGreat Depressionand World War II accelerated the shift away fromsmallholderfarming to larger farms, and began a trend of urbanization. The period after World War II witnessed a particular increase in manufacturing operations.

In 1975, Governor Robert D. Ray petitioned President Ford to allow Iowa to accept and resettleTai Damrefugees fleeing the Indochina War.An exception was required for this resettlement as State Dept policy at the time forbid resettlement of large groups of refugees in concentrated communities; an exception was ultimately granted and 1200 Tai Dam were resettled in Iowa. Since then Iowa has accepted thousands of refugees from Laos, Cambodia, Thailand, Bhutan, and Burma.

Thefarm crisisof the 1980s caused a major recession in Iowa, causing poverty not seen since the Depression.The crisis spurred a major, decade-long population decline.

Reemergence as a mixed economy, 1985–present

After bottoming out in the 1980s, Iowa's economy began to reduce its dependence on agriculture. By the early 21st century, it was characterized by a mix of manufacturing, biotechnology, finance and insurance services, and government services.The population of Iowa has increased at a slower rate than the U.S. as a whole since at least the1900 census,though Iowa now has a predominantly urban population.The Iowa Economic Development Authority, created in 2011 has replaced the Iowa Department of Economic Development and its annual reports are a source of economic information.

Topography of Iowa, with counties and major streams

Iowa is bordered by theMississippi Riveron the east along with theMissouri Riverand theBig Sioux Riveron the west. The northern boundary is a line along 43 degrees, 30 minutes north latitude.The southern border is theDes Moines Riverand a not-quite-straight line along approximately 40 degrees 35 minutes north, as decided by theU.S. Supreme CourtinMissouri v. Iowa(1849) after a standoff betweenMissouriand Iowa known as theHoney War.

Iowa is the only state whose east and west borders are formed almost entirely by rivers.Carter Lake, Iowa,is the only city in the state located west of the Missouri River.

Iowa has 99counties,but 100county seatsbecauseLee Countyhas two. The state capital,Des Moines,is inPolk County.

Geology and terrain

Iowa terrain

Iowa's bedrock geology generally decreases in age from east to west. In northwest Iowa,Cretaceousbedrock can be 74 million years old; in eastern IowaCambrianbedrock dates to c. 500 million years ago.The oldest radiometrically dated bedrock in the state is the 2.9 billion year old Otter Creek Layered Mafic Complex.Precambrianrock is exposed only in the northwest of the state.

Iowa can be divided into eightlandformsbased onglaciation,soils,topography,and river drainage.Loesshills lie along the western border of the state, some of which are several hundred feet thick.Northeast Iowa along theUpper Mississippi Riveris part of theDriftless Area,consisting of steep hills and valleys which appear as mountainous.

Several natural lakes exist, most notablySpirit Lake,West Okoboji Lake,andEast Okoboji Lakein northwest Iowa (seeIowa Great Lakes). To the east liesClear Lake.Man-made lakes include Lake Odessa,Saylorville Lake,Lake Red Rock,Coralville Lake,Lake MacBride, and Rathbun Lake. Before European settlement, 4 to 6 million acres of the state was covered with wetlands, about 95% of these wetlands have been drained.

Ecology and environment

Main article:Environment of Iowa

Landforms of Iowa

Iowa's natural vegetation istallgrass prairieandsavannain upland areas, with dense forest and wetlands in flood plains and protected river valleys, and pothole wetlands in northern prairie areas.Most of Iowa is used for agriculture; crops cover 60% of the state, grasslands (mostly pasture and hay with some prairie and wetland) cover 30%, and forests cover 7%; urban areas and water cover another 1% each.

The southern part of Iowa is categorized as theCentral forest-grasslands transitionecoregion.The Northern, drier part of Iowa is categorized as part of theCentral tall grasslands.

There is a dearth of natural areas in Iowa; less than 1% of thetallgrass prairiethat once covered most of Iowa remains intact; only about 5% of the state's prairie pothole wetlands remain, and most of the original forest has been lost.As of 2005Iowa ranked 49th of U.S. states in public land holdings.Threatened or endangered animals in Iowa include theinterior least tern,piping plover,Indiana bat,pallid sturgeon,theIowa Pleistocene land snail,Higgins' eye pearly mussel,and theTopeka shiner.Endangered or threatened plants includewestern prairie fringed orchid,eastern prairie fringed orchid,Mead's milkweed,prairie bush clover,andnorthern wild monkshood.

The explosion in the number ofhigh-density livestock facilitiesin Iowa has led to increased rural water contamination and a decline in air quality.

Other factors negatively affecting Iowa's environment include the extensive use of oldercoal-fired power plants,fertilizer and pesticide runoff from crop production,and diminishment of theJordan Aquifer.

The2020–2023 North American droughthas affected Iowa particularly: As of January 2024, Iowa was in its 187th consecutive week of at least moderatedrought,the longest stretch since the 1950s. 96% of areas are affected by drought.

As of 2008, Iowa averaged about 50 days ofthunderstormactivity per year.As of 2015, the 30-year annual average of tornadoes in Iowa was 47.In2008,twelve people were killed by tornadoes in Iowa, making it the deadliest year since1968and also the second most tornadoes in a year with 105, matching the total from 2001.

Iowa summers are known for heat and humidity, with daytime temperatures sometimes near 90 °F (32 °C) and occasionally exceeding 100 °F (38 °C). Average winters in the state have been known to drop well below freezing, even dropping below −18 °F (−28 °C). As of 2018, Iowa's all-time hottest temperature of 118 °F (48 °C) was recorded at Keokuk on July 20, 1934, during a nationwide heat wave;as of 2014, the all-time lowest temperature of −47 °F (−44 °C) was recorded inWashtaon January 12, 1912.

Precipitation

Iowa has had a relatively smooth gradient of varyingprecipitationacross the state; from 1961 to 1990, areas in the southeast of the state received an average of over 38 inches (97 cm) of rain annually, and the northwest of the state receiving less than 28 inches (71 cm).The pattern of precipitation across Iowa is seasonal with more rain falling in the summer months. Virtually statewide, the driest month is January or February, and the wettest month is June owing to frequent showers and thunderstorms some of which produce hail, damaging winds or tornadoes. In Des Moines, roughly in the center of the state, over two-thirds of the 34.72 inches (88.2 cm) of rain falls from April through September, and about half the average annual precipitation falls from May through August peaking in June.

Settlements

Percent population changes by counties in Iowa, 2000–2009; dark green counties have gains of more than 5%

See also:List of cities in IowaandList of largest Iowa cities by population

Iowa's population is more urban than rural, with 61 percent living in urban areas in 2000, a trend that began in the early 20th century.Urban counties in Iowa grew 8.5% from 2000 to 2008, while rural counties declined by 4.2%.The shift from rural to urban has caused population increases in more urbanized counties such asDallas,Johnson,Linn,Polk,andScott,at the expense of more rural counties.

Iowa, in common with other Midwestern states (especiallyKansas,Nebraska,North Dakota,andSouth Dakota), is feeling the brunt ofrural flight,although Iowa has been gaining population since approximately 1990. Some smaller communities, such asDenisonandStorm Lake,have mitigated this population loss through gains in immigrant laborers.

Another demographic problem for Iowa is thebrain drain,in which educated young adults leave the state in search of better prospects in higher education or employment. During the 1990s, Iowa had the second highest exodus rate for single, educated young adults, second only to North Dakota.

Ethnic origins in Iowa

TheUnited States Census Bureaudetermined the population of Iowa was 3,190,369 on April 1, 2020, a 4.73% increase since the2010 United States census.

Of the residents of Iowa, 70.8% were born in Iowa, 23.6% were born in a different U.S. state, 0.6% were born in Puerto Rico, U.S. Island areas, or born abroad to American parent(s), and 5% were foreign born.

Immigrationfrom outside the United States resulted in a net increase of 29,386 people, while migration within the country produced a net loss of 41,140 people. 6.5% of Iowa's population were reported as under the age of five, 22.6% under 18, and 14.7% were 65 or older. Males made up approximately 49.6% of the population.The population density of the state is 52.7 people per square mile.As of the2010 census,thecenter of populationof Iowa is inMarshall County,nearMelbourne.The top countries of origin for Iowa's immigrants in 2018 wereMexico,India,Vietnam,ChinaandThailand.

Germans are the largest ethnic group in Iowa. Other major ethnic groups in Iowa include Irish people and the British. There are also Dutch communities in state. The Dutch can be found in Pella, in the centre of the state, and in Orange City, in the northwest. There is a Norwegian community in Decorah in northeast Iowa; and there is Czech and Slovak communities in both Cedar Rapids and Iowa City. Smaller numbers of Greeks and Italians are scattered in Iowa's metropolitan areas. The majority of Hispanics in Iowa areMexican.African Americans,who constitute around 2% of Iowa's population, didn't live in the state in any appreciable numbers until the early 20th century. Many blacks worked in the coal-mining industry of southern Iowa. Others blacks migrated to Waterloo, Davenport, and Des Moines, where the black population remained substantial in the early 21st century.The African-American population in Des Moines experienced a significant increase with the establishment of the Colored Officers Training Camp at Fort Des Moines in 1917. Following the conclusion of World War I in 1918, numerous African-American families made the decision to remain in Des Moines. This marked the inception of a thriving community that eventually became a residence for numerous African-American leaders.

Presidential caucus

Main article:Iowa caucuses

The state gets considerable attention every four years because theIowa caucus,gatherings of voters to select delegates to the state conventions, is the first presidential caucus in the country. The caucuses, held in January or February of the election year, involve people gathering in homes or public places and choosing their candidates, rather than casting secret ballots as is done in apresidential primaryelection. Along with theNew Hampshire primarythe following week, Iowa's caucuses have become the starting points for choosing the two major-party candidates for president.The national and international media give Iowa and New Hampshire extensive attention, which gives Iowa voters leverage.In 2007 presidential campaign spending was the seventh highest in the country.

Civil rights

In a 2020 study, Iowa was ranked as the 24th easiest state for citizens to vote in.

Racial equality

TheUnion Blockbuilding inMount Pleasant,scene of early civil rights and women's rights activities

In the 19th century Iowa was among the earliest states to enact prohibitions against race discrimination, especially in education, but was slow to achieve full integration in the 20th century. In the first decision of theIowa Supreme Court—In Re the Matter of Ralph,decided July 1839—the Court rejected slavery in a decision that found a slave named Ralph became free when he stepped on Iowa soil, 26 years before the end of the Civil War.The state did away with racial barriers to marriage in 1851, more than 100 years before the U.S. Supreme Court would banmiscegenation statutesnationwide.

The Iowa Supreme Court decidedClark v. The board of directorsin 1868, ruling that racially segregated "separate but equal" schools had no place in Iowa, 85 years beforeBrown v. Board of Education.By 1875, a number of additional court rulings effectively ended segregation in Iowa schools.Social and housing discrimination continued against Blacks at state universities until the 1950s.The Court heardCoger v. The North Western Union Packet Co.in 1873, ruling against racial discrimination in public accommodations 91 years before the U.S. Supreme Court reached the same decision.

In 1884, the Iowa Civil Rights Act apparently outlawed discrimination by businesses, reading: "All persons within this state shall be entitled to the full and equal enjoyment of the accommodations, advantages, facilities, and privileges of inns, restaurants, chophouses, eating houses, lunch counters, and all other places where refreshments are served, public conveyances, barber shops, bathhouses, theaters, and all other places of amusement." However, the courts chose to narrowly apply this act, allowing de facto discrimination to continue.Racial discrimination at public businesses was not deemed illegal until 1949, when the court ruled inState of Iowa v. Katzthat businesses had to serve customers regardless of race; the case began whenEdna Griffinwas denied service at a Des Moines drugstore.Full racial civil rights were codified under the Iowa Civil Rights Act of 1965.

Women's rights

As with racial equality, Iowa was a vanguard in women's rights in the mid-19th century, but did not allow women the right to vote until theNineteenth Amendment to the United States Constitutionwas ratified in 1920, Iowa legislature being one of the ratifying votes.In 1847, theUniversity of Iowabecame the first public university in the U.S. to admit men and women on an equal basis.In 1869, Iowa became the first state in the union to admit women to the practice of law, with the Court ruling women may not be denied the right to practice law in Iowa and admittingArabella A. Mansfieldto the practice of law.Several attempts to grant full voting rights to Iowa women were defeated between 1870 and 1919. In 1894 women were given "partial suffrage", which allowed them to vote on issues, but not for candidates. It was not until the ratification of the Nineteenth Amendment that women had full suffrage in Iowa.Although Iowa supported the FederalEqual Rights Amendment,in 1980 and 1992 Iowa voters rejected an Equal Rights Amendment to the state constitution.Iowa added the word "women" to the Iowa Constitution in 1998. After the amendment, it reads: "All men and women are, by nature, free and equal, and have certain inalienable rights—among which are those of enjoying and defending life and liberty, acquiring, possessing and protecting property, and pursuing and obtaining safety and happiness."

In May 2018 Iowa signed into law one of the country's most restrictive abortion bans: the requirement that a doctor cannot perform an abortion if they can detect a fetal heartbeat, which in many cases would restrict abortions pregnancies less than six weeks old.It was struck down in January 2019, when an Iowa state judge ruled that the "fetal heartbeat" law was unconstitutional.

LGBT rights

Main article:LGBT rights in Iowa

The state's law criminalizing same-sex sexual activity was repealed in June 1976, 27 years beforeLawrence v. Texas.In 2007, the Iowa Legislature added "sexual orientation" and "gender identity" to the protected classes listed in the Iowa Civil Rights Act.

On April 3, 2009, the Iowa Supreme Court decidedVarnum v. Brien,holding in aunanimousdecision,the state's law forbiddingsame-sex marriagewasunconstitutional.This made Iowa the third state in the U.S. and first in the Midwest to permit same-sex marriage.
