title: Montana Vigilantes
context: The history of vigilante justice and the Montana Vigilantes began in 1863 in what was at the time a remote part of eastern Idaho Territory. Vigilante activities continued, although somewhat sporadically, through the Montana Territorial period until the territory became the state of Montana on November 8, 1889. Vigilantism arose because territorial law enforcement and the courts had very little power in the remote mining camps during the territorial period.
