The work of the Leavenworth County Historical Society is vital to preserving the unique history of the First City of Kansas. For more than 70 years, our progress has been made possible through dedicated volunteers, members, donors, and community partners. With continued support, the Society can care for the Carroll Mansion Museum, expand exhibits and programming, and preserve archival collections—including rare historic photographs and documents that tell Leavenworth County’s story.
Whether you give online, sponsor a project, attend an event, or become a member, every contribution helps protect local history and share it with the public.
