Which nonprofit serves as the administrative secretariat for the United States Semiquincentennial Commission?

The American Battlefield Trust serves as the administrative secretariat for the United States Semiquincentennial Commission.

The Trust was selected as the commission's nonprofit partner to help administer the planning effort. Its responsibilities include preparing reports for Congress and helping raise funds for anniversary observances.

The organization is best known for preserving and interpreting American battlefields. That background in historical education, preservation, fundraising, and large commemorative projects made it a suitable partner for a nationwide anniversary program.

The secretariat role is distinct from the commission itself. The commission is the congressional body responsible for national planning, while the American Battlefield Trust provides administrative and organizational support. The National Park Service is also involved in federal historical preservation but is not the commission's named nonprofit secretariat.
