Fort Langley dates from a time when the boundary between British and American possession of the trans-montan west, known as the Columbia District to the British and Oregon Country to Americans, had not yet been decided. Sir George Simpson, Governor of the Hudson's Bay Company, realized that Fort Vancouver opposite of present-day Portland, Oregon might be lost to the Americans if the border did not follow the Columbia River. Fearing the 49th parallel north could become the demarcation line, Simpson ordered the Hudson's Bay Company to construct the original Fort Langley in 1827 at a location 4 km downstream from its present site. Fort Langley was intentionally constructed on the south bank of the Fraser River in the event that Fort Vancouver was lost to the Americans, then Fort Langley would secure British claims to both sides of the Fraser. By 1830, Fort Langley had become a major export port for salted salmon in barrels, as well as cedar lumber and shingles to the Hawaiian Islands. The Cowlitz Portage overland route connected Fort Langley to Fort Vancouver with a mid-way stop at Fort Nisqually on Puget Sound. As Simpson feared, when the Oregon Boundary Dispute was finally settled in 1846, the border was established as 49 N. In the days before the Colony of Vancouver Island and the Colony of British Columbia united, Governor Sir James Douglas chose Fort Langley to be the provisional colonial capital.
