The Territory of Washington was an organized incorporated territory of the United States that existed from March 2, 1853, until November 11, 1889, when the territory was admitted to the Union as the State of Washington. It was created from the portion of the Oregon Territory north of the lower Columbia River and north of the 46th parallel east of the Columbia. At its largest extent, it also included the entirety of modern Idaho and parts of Montana and Wyoming, before attaining its final boundaries in 1863.
