In many ways the story of the Anaconda Copper Mining Company, through the first seven decades of the Twentieth Century, best illustrates trends in the Montana economy. The Anaconda Company dominated the state’s metals industry and influenced other business sectors. It developed a ‘copper press’ to manage journalism in the state, played a major role in the Montana legislature, and teamed with the Montana Power Company on many fronts. The Company’s ultimate demise tells a larger tale about the shift in Montana’s economic base. To many Montanans, the story of the Anaconda Company is the story of Twentieth Century Montana.
