Why Your Support Matters

The Leavenworth County Historical Society works every day to preserve and share the rich history of Leavenworth County—known as the First City of Kansas. Our organization maintains the historic Carroll Mansion Museum and protects thousands of artifacts, documents, and photographs that tell the story of our community and its role in American history.

For more than seventy years, the work of the Society has been made possible through the dedication of volunteers, members, and supporters who believe that preserving our past is essential for future generations.

Preserving Our Local Heritage

Leavenworth played an important role in the early history of Kansas and the expansion of the American West. From the days of riverboats and pioneer trails to the development of industry and the growth of Fort Leavenworth, the stories of this region are part of the broader story of our nation.

The Society safeguards these stories through:

  • Historic artifacts and archival collections
  • Educational exhibits and public programs
  • Research resources for historians, students, and genealogists
  • The preservation of the Carroll Mansion Museum, one of the region’s most significant historic buildings

Among the Society’s most remarkable collections are 30,000 historic glass plate negatives taken by early photographers—an archive considered a national treasure for documenting life in early Kansas.
