The year 1858 is the single most important year in British Columbia’s history. It was on 2 August of that year that an imperial act established the mainland colony of BC under the authority of Governor James Douglas. Beginning that spring, the Fraser River Gold Rush unleashed a chain of events that culminated a dozen years later in British Columbia joining the new Canadian Confederation. Without 1858, it is very possible there would have been no British Columbia, but rather an American state. Without 1858, Canada today might not extend from the Atlantic to the Pacific.
