Why did the Metis seize fort garry?

The Métis seized Fort Garry in 1869 as a response to concerns over the Canadian government's plans to annex the Red River area without addressing their rights and interests. Led by Louis Riel, they aimed to protect their land, culture, and political autonomy. The seizure was also motivated by fears that the influx of settlers would undermine their way of life. This action ultimately set the stage for negotiations that led to the creation of Manitoba as a province.
