Alaska boundary dispute

The Alaska boundary dispute was a territorial dispute between the United States and the British Empire over the Canada–United States border regarding Alaska between the 1890s and 1900s. As Canada was then a British dominion, the United Kingdom held the responsibility of negotiating with the American government over the dispute, which had existed since 1825 between Britain and Russia. Following the United States' acquisition of Alaska from Russia in 1867, the Canada–Alaska border continued to be disputed, which intensified following the 1897 Klondike Gold Rush in Yukon.

Eventually, Anglo-American negotiations led to the dispute being resolved by arbitration in 1903. The final resolution favored the American position, as Canada did not get an all-Canadian outlet from Yukon's gold fields to the Pacific Ocean. News of the dispute's outcome was met with widespread anger in Canada, which viewed the British government as betraying them by prioritizing better Anglo-American relations over Canadian interests.
