Hamilton was created on January 8, 1857 from Webster County. The County was named for William W. Hamilton, a president of the Iowa state senate who was influential in the creation of the county. The County Seat is Webster City.
Counties adjacent to Hamilton County are Wright County (north), Hardin County (east), Story County, Boone County (southwest), Webster County (west). Hamilton County Cities and Towns Include Blairsburg, Ellsworth, Jewell Junction, Kamrar, Randall, Stanhope, Stratford, Webster City, Williams.
When the county was originally organized in 1847 it was named Risley, after Colonel Risley who was killed in the Mexican War. It was later changed to Webster. Finally, Webster County was divided in half, and the eastern half was given the name of Hamilton in December 1856.
The same Legislative Act that established Hamilton County also named Webster City as the county seat in 1857. At an April 1858 election, it was proposed that the county use swamp land funds to construct the county’s first courthouse. The motion passed by a wide margin, and construction of the building began in the summer of 1858. But due to the lack of public support, funds, and county seat battles, the $50,000 building was never completed.
The first courthouse that was completed was in 1866. It was a temporary structure that cost $1,934 and was used until 1877. The second courthouse was originally to cost around $50,000, but was revised to $35,000. The winning bid of $30,000 and 1,360 acres of swamp land was submitted by John M. Rice of Chicago. The building was completed in June, 1877.
In 1974 the courthouse of 1877 was condemned. Construction of a $1.25 million building was begun later that same year and it was dedicated on December 4, 1976. It is a split-level brick building faced with Georgia black stone.
