The North-West Mounted Police, the forerunner of the Royal Canadian Mounted Police, was established to bring law and order to and assert Canadian sovereignty over the Northwest Territories.

The North-West Mounted Police (NWMP) was a Canadian paramilitary police force, established in 1873, to maintain order in the new Canadian North-West Territories (NWT) following the 1870 transfer of Rupert's Land and North-Western Territory to Canada from the Hudson's Bay Company, the Red River Rebellion and in response to lawlessness, demonstrated by the subsequent Cypress Hills Massacre and fears of United States military intervention. The NWMP combined military, police and judicial functions along similar lines to the Royal Irish Constabulary. A small, mobile police force was chosen to reduce potential for tensions with the United States and First Nations. The NWMP uniforms included red coats deliberately reminiscent of British and Canadian military uniforms.

The Royal Canadian Mounted Police is the national police service of Canada. The RCMP is an agency of the Government of Canada; it also provides police services under contract to 11 provinces and territories, over 150 municipalities, and 600 Indigenous communities. The RCMP is commonly known as the Mounties in English.

The Northwest Territories is a federal territory of Canada. At a land area of approximately 1,127,711.92 km² (435,412.01 sq mi) and a 2021 census population of 41,070, it is the second-largest and the most populous of the three territories in Northern Canada. Its estimated population as of the first quarter of 2025 is 45,242. Yellowknife is the capital, most populous community, and the only city in the territory; its population was 20,340 as of the 2021 census. It became the territorial capital in 1967, following recommendations by the Carrothers Commission.
