The '''Oregon Territory''' is the name applied both to the unorganized [[Oregon Country]] claimed by both the [[United States]] and [[United Kingdom|Britain]] (but normally referred to as the [[Oregon Country]]), as well as to the [[Organized incorporated territories of the United States|organized U.S. territory]] formed from it that existed between 1848 and 1859.
The Territory of Oregon was organized on [[August 14]], [[1848]], by an act of [[United States Congress|Congress]] out of the U.S. portion of the Oregon Country below the [[49th parallel north]]. It originally included all of the present-day states of [[Idaho]], [[Oregon]] and [[Washington]], as well as [[Montana]] west of the [[Continental Divide]], and [[Wyoming]] west of the Continental Divide and north of the [[42nd parallel north]], the boundary of the [[Adams-Onis Treaty]] of 1819.
The first territorial capital was [[Oregon City, Oregon|Oregon City]] from 1848 to 1851, followed by [[Salem, Oregon|Salem]] from 1851 to 1855. [[Corvallis, Oregon|Corvallis]] served briefly as the capital in 1855, followed by a permanent return to Salem later that year.
In 1853, the portion of the territory north of the lower [[Columbia River]] and north of the 46th parallel east of the river was organized into the [[Washington Territory]].
On [[February 14]], [[1859]], the territory entered the Union as the [[U.S. state]] of [[Oregon]] within its current boundaries. The remaining eastern portion of the territory (the portions in present-day southern Idaho and western Wyoming) was added to the Washington Territory.
In 1861 and then 1863, portions to the east were organized into the [[Nebraska Territory]] and [[Idaho Territory]] (respectively.)
