Louis Riel [SEP] Introduction
Because of this new religious conviction, Catholic leaders who had supported him before increasingly repudiated him. He married in 1881 while in exile in Montana in the United States; he fathered three children. In 1884 Riel was called upon by the Métis leaders in Saskatchewan to articulate their grievances to the Canadian government. Instead he organized a military resistance that escalated into a military confrontation, the North-West Rebellion of 1885. Ottawa used the new rail lines to send in thousands of combat soldiers. It ended in his arrest and conviction for high treason. Despite protests and popular appeals, Prime Minister Macdonald rejected calls for clemency, and Riel was executed by hanging.
