In 1873, the North-West Mounted Police were established to maintain law and order in the North-West Territories. They undertook a trek from Fort Dufferin, south of Winnipeg, to Fort Whoop-up, near present-day Lethbridge, Alberta. The force raised the flag and proclaimed the Queen's Law, ensuring that the Canadian West would not become a lawless, American-style frontier.
