The future county's first permanent settlement was Rushville, founded in 1846 by persecuted members of the Church of Jesus Christ of Latter-day Saints as they were being driven out of Nauvoo, Illinois. This is not to be confused with the state's present-day Rushville in Jasper County. A nearby settlement, also founded by the Mormon settlers, was called Coonsville after Dr. Liberius Coons, one of the first arrivals. That settlement continued after the Mormons moved on; its name was changed to Glenwood in 1853.
In Glenwood, the first courthouse was a small frame building which served until 1857. It was replaced by a two-story building, which was enlarged in the 1900s and received a clock tower in 1910. In 1959 this building was replaced with the present building, dedicated on August 29, 1959.[5]

Politics
Mills County is one of the most consistently Republican counties in Iowa. It has backed the Republican in all but five elections in its history, its inaugural election in 1852 prior to the founding of the Republican Party, in 1912 when former Republican turned ProgressiveTheodore Roosevelt caused a split in the vote, allowing Democrat Woodrow Wilson to take the county with a sub-40% plurality, in the two landslide victories for Franklin D. Roosevelt in 1932 and 1936, and for Lyndon B. Johnson in his 1964 landslide, who even then barely took Mills County by only 39 votes and less than 1%.
