The Oregon Treaty between the United States and the British. Signed by President James K. Polk on June 15, 1846. Frederick Merk`s statement that „the entire British press” greeted the news of the Senate`s ratification of lord Aberdeen`s proposed treaty with „a sigh of relief” and „universal satisfaction” is almost true. The Whigs, Tory and independent newspapers agreed with the treaty in their statements of satisfaction. Although some newspapers had reservations that were mild to say the least, the harsh condemnation that had hosted the old Webster Ashburton Treaty (which fixed the northeastern border between the United States and Canada) was totally missing. Lord Aberdeen had been determined to prevent such a reaction to the Oregon Treaty and, apparently, he was very successful in this work.

Vancouver Island, along with all the coastal islands, was founded in 1849 as a colony on Vancouver Island. ==.
