History

Barnes City was founded under the name of New Barnes until the town of Barnes City was chartered in 1898. Barnes City came about as a result of the Chicago, Rock Island, and Pacific Railroad needing a central link between Montezuma and Thornburg. It was decided that a small depot be built halfway in between these two communities, and this happened to be on the property owned by James Barnes in 1881; hence the name Barnes City.
