The Vancouver area was inhabited by a variety of Native American tribes, most recently the Chinook and Klickitat nations, with permanent settlements of timber longhouses. The Chinookan and Klickitat names for the area were reportedly Skit-so-to-ho and Ala-si-kas, respectively, meaning "land of the mud-turtles." First European contact was made in 1775, with approximately half of the indigenous population dead from smallpox before the Lewis and Clark expedition camped in the area in 1806. Within another fifty years, other actions and diseases such as measles, malaria and influenza had reduced the Chinookan population from an estimated 80,000 "to a few dozen refugees, landless, slaveless and swindled out of a treaty." Meriwether Lewis wrote that the Vancouver area was "the only desired situation for settlement west of the Rocky Mountains." The first permanent European settlement did not occur until 1824, when Fort Vancouver was established as a fur trading post of the Hudson's Bay Company. From that time on, the area was settled by both the US and Britain under a "joint occupation" agreement. Joint occupation led to the Oregon boundary dispute and ended on June 15, 1846, with the signing of the Oregon Treaty, which gave the United States full control of the area.
