Tierra de Santander (in OTL, Columbia or the Oregon Territory) was a region which was colonized relatively late in the colonization race (colonization started only in 1805 under Spaniard hands). The colonization of the region was slow and difficult, and by 1875, the territory was divided in British Rupert's Land, USPK Alaska, and Hispanic Tierra de Santander (part of the Kingdom of Mexico). The land was disputed by all three powers.
