The North-West Mounted Police (NWMP) was established in 1873 as a law enforcement agency in Canada's western territories, primarily tasked with maintaining order and enforcing laws during the settlement of the West. Created under Prime Minister John A. Macdonald, the NWMP played a crucial role in the development of Canada's western regions and the enforcement of treaties with Indigenous peoples, reflecting Macdonald's vision of national unity and expansion.
