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.
