Some Métis from the British territory to the north settled in Montana in the latter half of the 19th century. For a time, Louis Riel, the Métis leader from Manitoba in exile, taught school at St. Peter's Mission in Montana and was active in the local Republican Party. Democrats alleged he helped Métis men, who were not American citizens, to vote for the Republicans. In the summer of 1884, a delegation of Métis leaders including Gabriel Dumont and James Isbister, convinced Riel to return north, where in the following year he led the Métis revolt against Canadian rule, known as the North-West Rebellion. Following the defeat of the Métis rebels and the imprisonment and later hanging to Riel, Gabriel Dumont fled to exile in Montana.
