Anaconda was founded by Marcus Daly, one of the Copper Kings, who financed the construction of the Anaconda smelter on nearby Warm Springs Creek to process copper ore from the Butte mines. In June 1883, Daly filed for a town plat for Copperopolis, but that name was already used by another mining town in Meagher County. Instead, Daly accepted the name Anaconda, suggested by the United States postmaster of the time, Clinton Moore. Moore chose the name because of the important mine already existing in the area. When Montana was admitted as a state in 1889, Daly lobbied to have the capital moved here, but it stayed in Helena, a location supported by rival William Andrews Clark.
