Iowa (steamboat)
steamboat

The Steamboat Iowa was revered as one of the largest and fastest boats on the Mississippi in the mid 19th century; it is incorporated into the official Seal of Iowa. Built in 1838, the Iowa was the first vessel named for the newly formed Territory of Iowa. It weighed 112 tons, could pull 10 keelboats, and 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 Iowa sank after a collision with the steamboat Declaration on Oct. 1, 1847 while traveling from New Orleans to St. Louis. This liability for this collision was ultimately decided by the U.S. Supreme Court case John Walsh v. Patrick Rogers (54 U.S. 283–1852). However, the Iowa was apparently rebuilt, or a new steamboat was later rechristened Iowa, since similar side-wheeler appeared twice in Barber and Howe's 1865 Loyal West in the Time of Rebellion, and there is reference to the Iowa being used as a troop transport during the Civil War.
This brief starts where responsible research should: with the source description of “Iowa (steamboat)” as steamboat. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as steamboat. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q6064232. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1838, 1843, 1849 and 1847.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
