This bill designates the Quindaro Townsite in Kansas City, Kansas, as a **National Historic Landmark**, recognizing its profound historical significance. The site played a crucial role in the **Free-State movement** during the "Bleeding Kansas" conflict, serving as a safe port of entry for those opposed to slavery and as a key stop on the **Underground Railroad**. Its archaeological integrity and potential for further discoveries underscore its exceptional value in illustrating United States history, building upon significant local preservation efforts. To support the Landmark, the legislation authorizes the Secretary of the Interior to enter into **cooperative agreements** with public or private entities, providing technical and financial assistance for resource protection and public education programs. Importantly, the bill ensures that this designation does not restrict actions by property owners within the Landmark area, nor does it affect the existing administration of the site by Kansas City, Kansas, or the State.
