Fort Larned was established in 1859 as a base of military operations against hostile Indians of the Central Plains, to protect traffic along the Santa Fe Trail and as an agency for the administration of the Central Plains Indians by the Bureau of Indian Affairs under the terms of the Fort Wise Treaty of 1861. With nine restored buildings, it survives as one of the best examples of Indian Wars period forts. Most of the buildings including: barracks, commissary, officers quarters and more, are furnished to their original appearance. Fort Larned National Historic Site takes visitors back to this turbulent era in our nation's history.

Promises made and broken! A town attacked at dawn! Thousands made homeless by war! Soldiers fighting settlers! Each of these stories is a link in the chain of events that encircled Fort Scott from 1842-73. All of the site’s 20 historic structures, its parade ground, and its five acres of restored tallgrass prairie bear witness to this era when the United States was forged from a young divided republic into a united and powerful transcontinental nation. It is the mission of the National Park Service at Fort Scott National Historic Site to preserve, protect and interpret nationally significant historic resources related to the opening of the West, the Permanent Indian Frontier, the Mexican-American War, Bleeding Kansas, the Civil War and the expansion of railroads.

This area preserves, protects and interprets the only remaining western town established by African Americans during the Reconstruction Period following the Civil War. The town of Nicodemus is symbolic of the pioneer spirit of African-Americans who dared to leave the only region they had been familiar with to seek personal freedom and the opportunity to develop their talents and capabilities.

On October 26, 1992, Congress passed Public Law 102-525 establishing Brown v. Board of Education National Historic Site to commemorate the landmark Supreme Court decision aimed at ending segregation in public schools. On May 17, 1954, the Supreme Court unanimously declared that separate educational facilities are inherently unequal" and, as such, violate the 14th Amendment to the United States Constitution, which guarantees all citizens "equal protection of the laws." The site consists of the Monroe Elementary School, one of the four segregated elementary schools for African American children in Topeka, and the adjacent grounds.

On November 12, 1996, legislation was passed creating Tallgrass Prairie National Preserve in the Flint Hills region of Kansas. The preserve protects a nationally significant example of the once vast tallgrass ecosystem. Of the 400,000 square miles of tallgrass prairie that once covered the North American Continent, less than 4 percent remains, primarily in the Flint Hills. Tallgrass Prairie National Preserve is a new kind of national park. The preserve offers a historic ranch headquarters area with buildings dating from the late 19th century; a late 19th century one-room school house; two nature trails that offers some magnificent views of the Flint Hills landscape; and acres of prairie lands.

The Pony Express National Historic Trail was used by young men on fast paced horses to carry the nation's mail across the country, from St. Joseph, Missouri to Sacramento, California, in the unprecedented time of only ten days. Organized by private entrepreneurs, the horse-and-rider relay system became the nation's most direct and practical means of east-west communications before the telegraph. Though only in operation for 18 months, between April 1860 and October 1861, the trail proved the feasibility of a central overland transportation route, and played a vital role in aligning California with the Union in the years just before the Civil War. Most of the original trail has been obliterated either by time or human activities. Along many segments, the trail's actual route and exact length are matters of conjecture. However, approximately 120 historic sites may eventually be available to the public, including 50 existing Pony Express stations or station ruins.
