'' chuffing up the Mississippi through
Dubuque, Iowa, ca. 1865. The symbols presented on the seal reflect things important to early Iowa settlers. •
Citizen soldier. The seal was approved during the
Mexican–American War of 1846–1848, and the citizen soldier depicted with a "liberty cap" represents volunteer soldiers from Iowa. Battles of the Mexican-American war are memorialized in several Iowa place names, including the counties of
Buena Vista,
Palo Alto and
Cerro Gordo. As is traditional in official symbols, weapons are held in the soldier's left hand, and items of peace and freedom in the right. •
Liberty Cap. A "liberty cap", also called a
Phrygian cap, is a brimless hat resembling a tall beret that is an ancient Greek symbol of freedom. However, the soldier on the seal typically wears a wide-brimmed hat that resembles a Civil War-era Cavalry hat. Most versions of the seal put the liberty cap on top of the flag staff, in imitation of a
Liberty pole. •
Wheat. Early settlers in the 1840s primarily planted wheat, and it was not until the introduction of the railroad in the 1850s and 1860s that
corn became the primary crop grown in Iowa. •
Lead. Lead mining in the
Dubuque region was an early economic force; no lead is mined in Iowa today. A "pig" is a large slab of lead shaped in a furnace mold, with four corners protruding slightly to facilitate handling; thought to resemble the animal
pig. •
Steamer Iowa. The
Steamboat Iowa was revered as one of the largest and fastest boats on the Mississippi; it set the speed record from
Galena, Illinois to
St. Louis in 1843, making the trip in 44 hours, a record that held until 1849. The Mississippi was the primary route of transportation in Iowa in the 1840s, and most large Iowa towns were on or near the Mississippi. •
Eagle. The federal eagle was used in the earlier Seal of the Iowa Territory, and this symbol holding a banner with the motto of Iowa on it was incorporated into the
flag of Iowa. =="Plow in his rear" controversy==
