After gold was discovered in the Klondike region in 1896, the area saw a large influx of prospectors enter into the region in search of gold. Due to the large influx of prospectors into the region, the western portion of the Northwest Territory was split from the rest of the territory in 1898 to form Yukon. Although the gold rush ended by the turn of the century, mining developments continued to take place in the territory during the early 20th century. During the Second World War, the Alaska Highway was built through the territory in order to facilitate the transportation of supplies to Alaska. In 1953, the capital of the territory was moved from Dawson City to Whitehorse. From the late-20th century, a number of First Nations in Yukon have entered into land claim negotiations with the government of Canada.
