Iowa was the 29th state in the USA; it became a state on December 28, 1846. - State Capital is Des Moines. - Nickname is Hawkeye State. - Iowa's official flag was adopted in 1921. The flag was designed by by Mrs. Dixie Gebhardt, of The Daughters of the American Revolution of Iowa. The flag has a red, white and blue background, like the French flag; this symbolizes the fact that Iowa became a part of the United States as part of the Louisiana Purchase (this area had been part of France, but was sold to the USA in 1803). On the white central portion of the flag, a bald eagle holds a flowing ribbon that reads, "OUR LIBERTIES WE PRIZE, AND OUR RIGHTS WE WILL MAINTAIN."
