The county was formally organized in 1871; up to this time, it had been administered from, and taxed by, Saline County, its neighbor to the east. In April, an election was held to choose officers to organize the county; at this time, it was decided to place the county seat in the county's center. The town site was surveyed and platted, and given the name "Henry". It could not be occupied, since it was on school land owned by the State; an act of the Legislature was necessary before the land could be sold.
