In 1905, a short stretch of Alaska`s southeastern border, not defined by the price and later agreed by the commissioners, was officially accepted by the two countries in an exchange of notes. The 1818 treaty provided for the expansion of British North America and the United States, where the border stretched west along the 49th parallel, from the northwest corner of Lake of the Woods to the Rocky Mountains. The treaty erased British claims south of this line to the Red River Valley, which was part of Rupert`s Land. The treaty also wiped out U.S. claims to land north of that line in the Missouri River watershed, which was part of the Louisiana Purchase. Fortunately, Solomon`s wisdom finally prevailed. President Polk, the bellicose expansionist, proved about 120 years earlier that only Nixon could go to China, and simply agreed to open the border on the 49th anniversary of the war. Latitude to continue west. Basically, the border dispute between Britain and the United States revolved around which side Puget Sound Land and the rest of Washington State west and north of the Columbia River would get. In this competition, the British initially had by far the strongest hand. After all, Englishman George Vancouver was the first non-Native to discover and explore Puget Sound. And British fur traders, particularly in the service of the Hudson`s Bay Company, had established permanent bases in western Washington as part of the organization of the entire region into a commodity resource economy. By the 1830s the H.S.
Bay Company had established posts at Fort Vancouver and Fort Nisqually and along the Cowlitz Rover, and had also established cordial relations with the Native Americans. Many of George Simpson`s designs for the Columbia Department between 1824 and 1840 were based on the assumption that the British would retain western Washington and lose eastern Washington, Oregon, and Idaho. .
