History

The county had been established from the combination of Cragin and Wetmore Counties, which had both been formed in 1873. The county commission first met on August 29, 1881, and named Plankinton the county seat, an act which was ratified by voters in November 1882. Aurora County was reduced in size in 1883, when the northern part of the county was established as Jerauld County.
