Final answer:
The National Policy led to the Métis uprising as the Métis, under Louis Riel, feared the loss of their lands and culture. They formed a provisional government to demand the protection of their rights, resulting in the creation of Manitoba after the conflict.
Step-by-step explanation:
The National Policy, implemented by the Canadian government, aimed to promote economic development through high tariffs, railway expansion, and settlement of the West. This policy directly impacted the Métis, who were largely French-speaking and Roman Catholic. They feared the loss of their land and culture under the Dominion's English-speaking Protestant majority, leading to an uprising. Louis Riel united and led the Métis to oppose the government's attempts to survey Rupert's Land. He formed a provisional government demanding protection for Métis rights including the right to establish French-language schools.
Following the resistance, the Canadian Parliament granted the Métis 200,000 hectares of land, leading to the formation of the province of Manitoba in 1870. This occurrence was part of a larger pattern of Indigenous resistance and conflict on the North American continent, as seen in other events such as Pontiac's Rebellion and the Northwest Indian War, where Native American tribes fought against colonial or American expansion and control over their lands, trade, and sovereignty.
