Final answer:
Louis Riel led the Métis in the Red River Rebellion in 1870 and the Northwest Rebellion in 1885, which resulted in the establishment of the province of Manitoba and the protection of Métis rights.
Step-by-step explanation:
The leader of the Métis in the rebellions at Red River in 1870 and in the northwest in 1885 was Louis Riel.
The Métis, who were largely French-speaking and Roman Catholic, feared the loss of their land and culture under the Dominion's English-speaking Protestant majority.
Under the leadership of Louis Riel, they formed a provisional government to negotiate with Canada, leading to an outbreak of violence.
The Canadian government eventually granted the Métis 200,000 hectares of land, which led to the creation of the new province of Manitoba in 1870.
