where does the name british columbia come from
The province's name was chosen by Queen Victoria, when the Colony of British Columbia (1858 -- 66), i.e., "the Mainland", became a British colony in 1858. It refers to the Columbia District, the British name for the territory drained by the Columbia River, in southeastern British Columbia, which was the namesake of the pre-Oregon Treaty Columbia Department of the Hudson's Bay Company. Queen Victoria chose British Columbia to distinguish what was the British sector of the Columbia District from the United States ("American Columbia" or "Southern Columbia"), which became the Oregon Territory on August 8, 1848, as a result of the treaty.
