An influx of American gold-miners prompted Great Britain to proclaim the crown colony of British Columbia in 1858. The southern part of what is now the province was known as the Columbia Department during the fur-trade era, after the Columbia River. Although the major portion of British Columbia was called New Caledonia by the fur-traders, this name (duplicated in the South Pacific) was discarded by Queen Victoria in favor of the present name.

The name appear on the 1859 Arrowsmith map, entitled “Provinces of British Columbia and Vancouver Island; with portions of the United States and Hudson’s Bay Territories.”

“British Columbia / Colombie-Britannique” is among the 75 “Pan-Canadian names,” large and well-known Canadian features and areas designated in Treasury Board Circular 1983-58 to require presentation in both official languages of Canada on federal maps.
