Commemorating America’s Semiquincentennial

The United States will commemorate its 250th (or “Semiquincentennial”) anniversary in 2026. AASLH is providing key leadership for the history community as we all prepare for this once-in-a-generation event. We are monitoring national, regional, and state commemoration plans as they develop, serving as a clearinghouse of information for history organizations and practitioners at the local, state, and national levels, particularly through the publication of an annual report on the status of commemoration efforts. We are in communication with other national initiatives, including the U.S. Semiquincentennial Commission, to help ensure that the values and goals of the history community are represented well in national commemoration efforts. We have organized a national coordinating committee, facilitating communication and collaboration among major organizations, institutions, and agencies. Finally, we are outlining major goals for the anniversary that can help align the work of a diverse and dynamic field over the next several years.

After holding listening sessions about these goals at major conferences, including AASLH, National Council on Public History, Association of African American Museums, and the Association of Tribal Archives, Libraries, and Museums, AASLH has convened working groups to help consider them more deeply. These working groups will provide ideas and action plans to help guide the work of the field.
