Butte County was established in 1883. The county was formed as an outgrowth of a fight over the location of the capital of the Dakota Territory. In January 1883 a session of the Territorial Council was held to determine if Yankton would remain the capital of the Dakota Territory. The session created 59 new counties and a bill passed to divide Lawrence County into two counties, Lawrence and Butte. Governor Ordway designated Minnesela as the county seat. By 1894 Minnesela was a defunct community. Belle Fourche had built a 2-story building and offered it to Butte County if they would move the county seat to Belle Fourche. Following a brief fight, Belle Fourche won by a landslide.
