Macdonald then renamed the force the North-West Mounted Police (NWMP) when formed in 1873. The force added Royal to its name in 1904. It merged with the Dominion Police, the main police force for all points east of Manitoba, in 1920 and was renamed as the Royal Canadian Mounted Police. The Royal Canadian Mounted Police (RCMP; French: Gendarmerie royale du Canada (GRC), Royal Gendarmerie of Canada; colloquially known as the Mounties, and internally as the Force) is both a federal and a national police force of Canada.
