Iowa () is a U.S. state in the Midwestern United States, bordered by the Mississippi River to the east and the Missouri and Big Sioux rivers to the west. It is bordered by six states; Wisconsin to the northeast, Illinois to the east, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north.
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 is the 26th most extensive in land area and the 30th most populous of the 50 U.S states. Its capital and largest city by population is Des Moines. Iowa has been listed as one of the safest states in which to live. Its nickname is the Hawkeye State.
