Dominion Police
The Dominion Police Force was the federal police force of Canada between 1868 and 1920, and was one of the predecessors of the Royal Canadian Mounted Police. It was the first federal police force in Canada, formed the year following the Canadian Confederation to enforce federal laws and perform policing duties for the Federal Government of Canada. On 1 February 1920, the Dominion Police was merged with the North-West Mounted Police to form the Royal Canadian Mounted Police as the new federal police force of Canada.
Mounted police
The French Maréchaussée—direct predecessors of the gendarmerie and the first national police force in a modern sense—were a corps of completely mounted constabulary from their establishment in the early 18th century. Poor roads and extensive rural areas made horse-mounted police a necessity in European states until the early 20th century. The establishment of organized law-enforcement bodies throughout Africa, Asia and the Americas during the colonial and post-colonial eras made the concept of predominantly horse-police accepted almost world-wide. Notable examples included the Royal Canadian Mounted Police, the Mexican Rurales, the British South African Police, the Turkish/Cypriot Zapiteh and the "caballeria" (mounted branch) of the Spanish Civil Guard.
