In colonial times, 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 made the transition to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production.
Iowa has been listed as one of the safest states in which to live. Its nickname is the Hawkeye State.

Iowa is the only state whose east and west borders are formed entirely by rivers.
Geology and terrain
Iowa's bedrock geology generally increases in age from west to east. In northwest Iowa, Cretaceous bedrock can be 74 million years old, in eastern Iowa Cambrian bedrock dates to c. 500 million years ago.
Iowa is generally not flat; most of the state consists of rolling hills. Iowa can be divided into eight landforms based on glaciation, soils, topography, and river drainage. Loess hills lie along the western border of the state, some of which are several hundred feet thick.
Northeast Iowa along the Mississippi River is part of the Driftless Zone, consisting of steep hills and valleys which appear almost mountainous.
Several natural lakes exist, most notably Spirit Lake, West Okoboji Lake, and East Okoboji Lake in northwest Iowa (see Iowa Great Lakes). To the east lies Clear Lake. Man-made lakes include Lake Odessa, Saylorville Lake, Lake Red Rock, Coralville Lake, Lake MacBride, and Rathbun Lake. The state's northwest area has many remnants of the once common wetlands, such as Barringer Slough.
Ecology and environment
Iowa's natural vegetation is tallgrass prairie and savanna in 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.
Threatened or endangered animals in Iowa include the interior least tern, piping plover, Indiana bat, pallid sturgeon, the Iowa Pleistocene land snail, Higgins' eye pearly mussel, and the Topeka shiner. Endangered or threatened plants include western prairie fringed orchid, eastern prairie fringed orchid, Mead's milkweed, prairie bush clover, and northern wild monkshood.
Iowa has a humid continental climate throughout the state with extremes of both heat and cold. Winters are often harsh and snowfall is common.
Iowa summers are known for heat and humidity, with daytime temperatures often near 90 °F (32 °C) and sometimes exceeding 100 °F (38 °C).
By the time European explorers and traders visited Iowa, American Indians were largely settled farmers with complex economic, social, and political systems. American Indians adapted to local environments and ecosystems, slowly becoming more sedentary as populations increased.
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 Indian 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 exploration 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 Indian 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 Indians. The Sauk and Meskwaki effectively controlled trade on the Mississippi in the late 18th century and early 19th century.
After the 1803 Louisiana Purchase, Congress divided the Louisiana Purchase into two parts -- the Territory of Orleans and the District of Louisiana. The latter, of which in was placed. Iowa was placed under United States jurisdiction of the Territory of Indiana.
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 Ho-Chunk, many of whom allied with the British, who had not abandoned claims to the territory.
Fort Madison was defeated by British-supported Indians 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.
Trade and Indian removal, 1814–1832
The U.S. encouraged settlement of the east side of the Mississippi and removal of Indians to the west.
Trade continued in furs and lead, but disease and forced population movement decimated Indian cultures and economies. A disputed 1804 treaty between Quashquame and William Henry Harrison that surrendered much of Illinois to the U.S. enraged many Sauk and led to the 1832 Black Hawk War. As punishment for the uprising, and as part of a larger settlement strategy, treaties were subsequently designed to remove all Indians from Iowa.
The Sauk and Meskwaki were pushed out of the Mississippi valley in 1832, out of the Iowa River valley in 1843, and out of Iowa altogether in 1846. 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 Meskawki to purchase the land; Indians were not usually permitted to do so. The Ho-Chunk were removed from Iowa in 1850, and the Dakota were removed by the late 1850s. Western Iowa around modern Council Bluffs was used as a way station for other tribes being moved west, including the Potawatomi.
U.S. settlement and statehood, 1832–1860
The first American settlers officially moved to Iowa in June 1833. On July 4, 1838, the U.S. Congress established the Territory of Iowa. President Martin Van Buren appointed Robert Lucas governor of the territory, which at the time had 22 counties and a population of 23,242.
On December 28, 1846, Iowa became the 29th state in the Union when President James K. Polk signed Iowa's admission bill into law.
Iowa has a long tradition of state and county fairs. The State Fair has been held every year since except for the year 1898 due to the Spanish–American War and the World's Fair being held in nearby Omaha, Nebraska. The fair was also a World War II wartime casualty from 1942–1945.
Civil War, 1861–1865
Iowa supported the Union during the Civil War, voting heavily for Abraham Lincoln. There were no battles in the state, although the battle of Athens, Missouri, 1861, was fought just across the Des Moines River from Croton, 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 to Samuel J. Kirkwood, its first wartime governor.
Agricultural expansion, 1865–1930
Following the Civil War, Iowa's population continued to grow dramatically. The introduction of railroads in the 1859s and 1860s transformed Iowa into a major agricultural producer.
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. In the economic sector, Iowa also has undergone considerable change. Beginning with the first farm-related industries developed in the 1870s, Iowa has experienced a gradual increase in the number of business and manufacturing operations.
Depression, World War II, and the rise of manufacturing, 1930 to present day
The transition from an agricultural economy to a mixed economy happened slowly. The Great Depression and World War II accelerated the shift away from smallholder farming to larger farms, and began a trend of urbanization that continues. The period since World War II has witnessed a particular increase in manufacturing operations. While agriculture continued to be the state's dominant industry, Iowans also produce a wide variety of products including refrigerators, washing machines, fountain pens, farm implements, and food products.
The Farm Crisis of the 1980s caused a major recession in Iowa, causing poverty not seen since the Depression. The crisis spurred a major population decline in Iowa that lasted a decade.
After bottoming out in the 1980s, Iowa's economy began to become increasingly less dependent on agriculture, and by the early 21st century was characterized by a mix of manufacturing, biotechnology, finance and insurance services, and government services.

Race and ancestry
According to the 2010 Census, 91.3% of the population was White (88.7% non-Hispanic white), 2.9% was Black or African American, 0.4% American Indian and Alaska Native, 1.7% Asian, 0.1% Native Hawaiian and other Pacific Islander, 1.8% from two or more races. 5.0% of the total population was of Hispanic or Latino origin (they may be of any race).
Iowa's population included about 97,000 foreign-born (3.3%). Iowans are mostly of Western European descent. The five largest ancestry groups in Iowa are: German (35.7%), Irish (13.5%), English (9.5%), American (6.6%), and Norwegian (5.7%).
English is the most common language used in Iowa, used by 94% of the population.
After English, Spanish is the second-most-common language spoken in Iowa, with 120,000 people in Iowa of Hispanic or Latino origin and 47,000 people born in Latin America. The third-most-common language is German, spoken by 17,000 people in Iowa; two notable German dialects used in Iowa include Amana German spoken around the Amana Colonies, and Pennsylvania German, spoken among the Amish in Iowa.
The only indigenous language used regularly in Iowa is Meskwaki, used around the Meskwaki Settlement.
While Iowa is often viewed as a farming state, in reality agriculture is a small portion of a diversified economy, with manufacturing, biotechnology, finance and insurance services, and government services contributing substantially to Iowa's economy.
Manufacturing is the largest sector of Iowa's economy. Major manufacturing sectors include food processing, heavy machinery, and agricultural chemicals.
Directly and indirectly, agriculture has been a major component of Iowa's economy.
Iowa's main agricultural products are hogs, corn, soybeans, oats, cattle, eggs, and dairy products. Iowa is the nation's largest producer of ethanol and corn and some years is the largest grower of soybeans.
In 2008, the 92,600 farms in Iowa produced 19% of the nation's corn, 17% of the soybeans, 30% of the hogs, and 14% of the eggs.
Ethanol production consumes approximately one-third of Iowa's corn production, and renewable fuels account for 8% of the state's gross domestic product. A total of 39 ethanol plants produced 3.1 billion US gallons (12,000,000 m3) of fuel in 2009.
Renewable energy has become a major economic force in northern and western Iowa, with wind turbine electrical generation increasing exponentally since 1990. In 2010, wind power in Iowa accounted for 15.4% of electrical energy produced, and 3675 megawatts of generating capacity had been installed at the end of the year.
Iowa ranked first of U.S. states in percentage of total power generated by wind and second in wind generating capacity behind Texas.
Des Moines is the largest city in Iowa and the state's political and economic center. It is home to the Iowa State Capitol, the State Historical Society of Iowa Museum, Drake University, Des Moines Art Center, Greater Des Moines Botanical Garden, Principal Riverwalk, the Iowa State Fair, Terrace Hill, and the World Food Prize. Nearby attractions include Adventureland and Prairie Meadows Racetrack Casino in Altoona, Living History Farms in Urbandale, Trainland USA in Colfax, and the Iowa Speedway and Valle Drive-In in Newton.
