Royal Canadian Mounted Police
The Royal Canadian Mounted Police (RCMP) was formed in 1920 by the merger of the Royal Northwest Mounted Police (RNWMP), founded in 1873, with the Dominion Police founded in 1868. The former was originally named the North West Mounted Police (NWMP), and was given the "Royal" prefix by King Edward VII in 1904. Much of the present-day organization's symbolism has been inherited from its days as the NWMP and RNWMP, including the distinctive Red Serge uniform, paramilitary heritage, and mythos as a frontier force. The RCMP-GRC wording is protected under the Trade-marks Act.
Despite its name, the RCMP is no longer an actual mounted police force, with horses only being used at ceremonial events. The predecessor NWMP and RNWMP had relied on horses for transport for most of their history, though the RNWMP was switching to automobiles at the time of the merger.
RCMP Security Service
In 1950, the Royal Canadian Mounted Police's Special Branch was formally established to conduct its counterintelligence operations. Prior to that, the branch was a component of the RCMP's Criminal Investigation Branch, where political security operations and criminal investigations were not distinct before 1936. The Mounties carried out extensive security service work since the force was reconstituted in 1920, when it merged with the Dominion Police and became the federal police agency solely responsible for national security. Between the wars, this work was overwhelmingly directed at the Communist Party and labour and the left more generally.
