Which territories were acquired under James K. Polk's administration ?

With the Oregon Treaty of 1846, Polk managed another significant land acquisition–this time without going to war–when his administration diplomatically settled a border dispute with the British and gained full control of the present-day states of Washington, Oregon and Idaho, as well as parts of Montana and Wyoming.
