Boone County is a county in the U.S. state of Iowa. As of the 2020 census, the population was 26,715. ^[1] Its county seat is Boone. ^[2]

Boone County comprises the Boone, IA Micropolitan Statistical Area, which is included in the Des Moines-Ames-West Des Moines, IA Combined Statistical Area.

History

The land that now forms Boone and several other Iowa counties was ceded by the Sac and Fox nation to the United States in a treaty signed on October 11, 1842.

On January 13, 1846, the legislative body of the Indiana Territory authorized creation of twelve counties in the Iowa Territory, ^[3] with general descriptions of their boundaries. ^[4] Boone County's name referred to Captain Nathan Boone, ^[5] son of Daniel Boone, an American pioneer who formed the Wilderness Trail and founded the settlement of Boonesborough, Kentucky.

County residents selected Boonesboro as the county seat in 1851. The first building erected in the new settlement was a double log house, to be used as interim county office and courthouse. It was supplemented by a two–story building erected in 1856, then replaced by a three-story building in 1868.

The nearby settlement of Montana was incorporated in 1866, when a railway station was built there. ^[6] It was renamed to Boone in 1871. ^[7] It continued to grow, and it annexed the settlement of Boonesboro (which had also been incorporated in 1866) in 1887, thus becoming the county seat. ^[7]

After the second courthouse became too small for the county's expanding populace, a new building (the present courthouse) replaced it. It was completed in 1917. ^[8]

Politics

Prior to 1932, Boone County was primarily Republican in presidential elections, aside from 1912 when the county backed Bull Moose candidate & former Republican President Theodore Roosevelt. From 1932 to 1980, the county was a swing county, voting for the national winner in all elections in that period aside from 1960. From 1984 to 2012, the county was consistently Democratic in presidential elections, but swung hard in 2016 by 20.7 points to back Republican Donald Trump similar to many other counties in Iowa. ^[19] In Republican presidential primaries, it holds the distinction of having the longuest streak of voting against the future nominee, having done so since the 1980 primary.
