Iowa Territory's At-large congressional district
Iowa Territory's At-large congressional district is an obsolete congressional district that encompassed the area of the Iowa Territory, which was split off from the Wisconsin Territory in 1838. After Iowa's admission to the Union as the 29th state by act of Congress on December 28, 1846, this district was dissolved and replaced by Iowa's At-large congressional district.
On June 12, 1838, an act of Congress gave Iowa Territory the authority to elect a delegate to Congress.
