April 3 – On this day in Montana history in 1885 in Miles City, Montana Territory, the Eastern Montana Livestock Association founded in 1883 and the Montana Stockgrowers Association founded in 1884 merged their operations under the name of the Montana Stockgrowers Association. The purpose of the group was “to unite cattle and horse growers in Montana Territory; first, for the enforcement of livestock laws; second, for the protection against rustlers; third, to devise plans to protect the open range against fires; fourth, for the uniformity in just claims against railroads and other corporations; and fifth, to promote harmony in range work and roundups.”
