Iowa Statehood
Iowa entered the Union as the agricultural interior was becoming central to the country's future, linking prairie settlement to equal state membership.
How This State Entered The Union
Statehood is where constitutional structure meets regional history: the point where a place entered the Union as an equal state.
Admission To The Union
Iowa became the twenty-ninth state on December 28, 1846, during the great era of Mississippi Valley settlement and growth.
Path To Statehood
Its route followed territorial organization, migration, and rising agricultural settlement across the prairie interior.
Why It Matters
Iowa matters because it shows how quickly productive interior land moved from frontier space to equal participation inside the Union.
