Iowa Territory[]

On July 4, 1838, the Iowa Territory was organized. Most of the area comprising the territory was originally part of the Louisiana Purchase and was a part of the Missouri Territory. When Missouri became a state in 1821, this area (along with the Dakotas) effectively became unorganized territory. The area was closed to white settlers until the 1830s, after the Black Hawk War ended. It was attached to the Michigan Territory on June 28, 1834, and was split off with the Wisconsin Territory in 1836 when Michigan became a state.

The Iowa Territory was the "Iowa District" of western Wisconsin Territory – the region west of the Mississippi River. The original boundaries of the territory, as established in 1838, included part of Minnesota and parts of the Dakotas, covering about 194,000 square miles (500,000 km²) of land.
