Fort Leavenworth () is a
United States Army installation located in
Leavenworth County, Kansas, in the city of

Leavenworth's instructions had been the following:
Colonel Leavenworth of the 3d Infantry, with four companies of his regiment will ascend the Missouri and when he reaches a point on its left band near the mouth of Little Platte River and within a range of twenty miles above or below its confluence, he will select such position as in his judgment is best calculated for the site of a permanent cantonment. The spot being chosen, he will then construct with the troops of his command comfortable, though temporary quarters sufficient for the accommodation of four companies. This movement will be made as early as the convenience of the service will permit.

Leavenworth was to report that spot around the confluence on the east side of the Missouri River (near present-day
Farley, Missouri) would be prone to flooding and on 8 May 1827 recommended the location upstream on the west bank in the bluffs above the river.

of 1830 attempted to remove all Indians west of the Missouri–Kansas border, the fort which is west of the border assumed even more importance. In 1832, it was renamed "Fort Leavenworth".
Between 1832 and 1834, the Rookery was built as bachelor officer quarters. The Rookery is the oldest building in Kansas and would be the office of the first territorial governor and thus the first capitol in Kansas from 1854 to 1855 when the capitol was moved to
Pawnee, Kansas.
In 1836,

Platte Purchase which involved the entire northwest corner of Missouri.

Andrew Reeder set up executive offices on post and lived for a short time in the quarters now known as the Rookery.
During the 1850s, troops from Ft. Leavenworth were mobilized to control the "Mormon Problem" in what became known as the
Utah War.

From 1858 to 1874 Fort Leavenworth was also home to the Fort Leavenworth Arsenal (originally called the Leavenworth Ordnance Depot) which supplied
ordnance to the army in the western United States which was located at what today is the Combined Arms Center headquarters complex on what is called Arsenal Hill which was reached by Arsenal Avenue (which today is called Scott Avenue). The arsenal moved in 1874 to the
Rock Island Arsenal in Illinois. Two surviving buildings from the arsenal are Sherman Hall and Sheridan Hall which are now in the same complex as Grant Hall and are among the most iconic buildings of the fort.

, Camp Lincoln was established on post as a reception and training station for Kansas volunteers. In 1864, news of the approach of
Confederate General
Sterling Price prompted construction of Fort Sully, a series of earthworks for artillery emplacements on Hancock Hill, overlooking what is now the
Fort Leavenworth National Cemetery. (See
Fort Sully (Fort Leavenworth)). However, Price's forces never reached Fort Leavenworth, having met defeat at
Westport, which is now part of
Kansas City. During its long history, the post was never subject to enemy attack.
For three decades following the war, the Army's chief mission was control of the
American Indian tribes on the Western plains. Between 1865 and 1891, the Army had more than 1,000 combat engagements with

The fort's first Catholic church was built in 1871 and was later replaced by St. Ignatius Chapel in 1889. St. Ignatius Chapel was destroyed by fire in December 2001. The first Protestant chapel, Memorial Chapel, was built by prison labor in 1878 of stone quarried on post. The round window behind the chapel's front altar was intentionally installed slightly askew by an inmate who was angry at his work boss. This chapel has brass cannon embedded in the walls at the sides of the church, and photos of many of the officers involved in the early history of the fort, including some of the Custer family.
In 1881, Gen.
William T. Sherman established the School of Application for Cavalry and Infantry. That school evolved into the
U.S. Army Command and General Staff College.
