Early French explorers who traveled through Iowa in the late 1600s encountered the Fox, Sauk, and Pottawatomie Indians. Julien Dubuque began mining lead in 1798. Though his fellow French-Canadians abandoned the settlement upon Dubuque’s 1810 death, a city bearing his name would rise there.
The United States acquired the land in 1803 as part of the Louisiana Purchase. In 1808, Iowa became part of Illinois Territory; in 1812, it became part of Missouri Territory. From 1821 to 1834, Iowa was not attached to any territory.
The Black Hawk War broke out in 1832. When it was over, the Fox and Sauk Indians were forced to relocate to Kansas, leaving Iowa open for legal settlement. The first settlements were in Eastern Iowa in 1833. After Indian claims to the land were extinguished in 1851, settlers poured into the area. The southern part of the state saw arrivals mostly from Kentucky and Tennessee. Settlers in the north were primarily from New England and the Mid- Atlantic, Ohio, Indiana and Illinois.
Iowa became part of Michigan Territory in 1834 and Wisconsin Territory in 1836. In 1838, Iowa Territory was formed; it included what would become Minnesota and parts of the Dakotas. In 1846, Iowa was the 29th state with Iowa City as its capital. In 1857, Des Moines became the capital.
During the 1850s, more people moved into Iowa from Ohio and Indiana, and many immigrants from Germany, Britain, and Ireland arrived. Iowa’s population tripled. The Amana colonists settled in Iowa. The last part of the 19th century saw heavy immigration from the Scandinavian countries.
