Nationally Important in the American West
Recognized by the National Park Service in the National Underground Railroad Network to Freedom program and the National Register of Historic Places, the Keeper of the National Register states:
The Topeka Constitutional Convention
In October 1855, forty delegates elected from across the Kansas Terrritory gathered here to write the antislavery Topeka Constitution, also known as the Free State Constitution. In 1856, this passed the U.S. House of Repsentatives, but was prevented from consideration by the proslavery Senate.
Dispersion of the Free State Legislature
In 1856 on the Fourth of July, four-hundred U.S. Army troops on horseback assembled in front of Constitution Hall. Calling it the most painful duty of his life, Col. Edwin V. Sumner dispersed the legislators.
The Lane Trail to Freedom
This was a free trade route used for escapes to freedom in the North and Canada. Constitution Hall was the "Quartermaster's Depot" on the Kansas Underground Railroad.
Capitol of Kansas, 1863-1869
Constitution Hall was the first Kansas Capitol while the current Statehouse was built five blocks to the south.
