Why was Louis Riel never able to take his seat?

Louis Riel was never able to take his seat in the Canadian Parliament due to his controversial status as a leader of the Métis people and his role in the Red River and North-West Rebellions. After leading the Red River Rebellion in 1869-70, he was elected as a Member of Parliament for Provencher in 1871, but he was in exile in the United States at the time and faced significant opposition, particularly from English-speaking Canadians who viewed him as a rebel. His mental health issues and the political climate of the time further complicated his return to Canada, preventing him from fulfilling his parliamentary duties. Ultimately, Riel's political career was overshadowed by his efforts to advocate for Métis rights and his tragic fate following the North-West Rebellion in 1885.
